HPE Zerto Software Reviews

We are using it to protect all our on-premise virtual workloads, which includes mission-critical applications, line of business applications, and several unstructured data type repositories for disaster recovery.

It is our sole disaster recovery solution for what it does. It is protecting all the workloads at SmartBank. 

Both of our data centers are on-premise and in colocations. Our plan over the next year or two is that we will very likely be shifting to DR in the cloud.

We had a ransomware event on one of our file servers. We detected that event very quickly using other methodologies. However, because we had Zerto in place on that server, within about 30 minutes from seeing the problem, we were able to go back and recover that machine before that ransomware event had happened. This is a great example of the solution's ability to restore so quickly that it really helped us.

Because of its ease of use, it has increased the number of people in IT who can failback or move workloads. This used to be something that was done only by our infrastructure team, because it was manual processes and complex. We now have the virtual protection setup so effectively, and Zerto does it so effectively, that we have now been able to get another three or four people from other groups of our IT company trained on how to do recovery operations. This helps us tremendously when we are doing recovery because there are just a lot more people who might be available to do it. On average, we have saved two hours per workload, and we have hundreds of workloads. We have taken about a two-hour process down to about 10 minutes in terms of recovery. Zerto is really good at what it does. It has been tremendous.

We can have a single person restoring scores of machines as well as doing DR. Backups are still managed separately. In our case, we did not reduce staff. Our staff was already kind of a limiting factor. We put Zerto in to enable our staff to do more, not to reduce our staff. Therefore, we have tremendously reduced the amount of workloads being handled by specialists.

The most valuable features are the ease of use, i.e., the relatively low complexity of the solution, as well as the speed and effectiveness of the solution. This allows us to protect our workloads with extremely small latency, making it very easy for us to monitor and recover. So, we are very happy with it.

In terms of Zerto providing continuous data protection, I would rate it as a nine out of 10. It is incredibly effective at what it does. I really have no complaints.

I would like to see more managed service= options. While Zerto isn't doing this a lot, there are a ton of third-parties who are doing managed services with Zerto.

For this company, we have only been using it for about six months. However, I have used it at two other companies for a total of about four years.

It is stable.

For our current needs, the scalability seems excellent. The scalability of the solution is really more of a function of your bandwidth and the amount of virtual resources you can point at it. I don't think there is any conceivable scalability limit.

Probably 10 people on my team touch Zerto in a meaningful way: 

• Four of them are infrastructure and data center engineers. They support the storage, users, communications, the software, and the configuration of most of the back-end system as well as monitor the solution. They do a lot there. 
• The other six people are our technical support director, enterprise applications team, and information security officer. Those people also get into Zerto. They generally do failover testing and monitor certain VPGs for parts of our system that they are responsible for, and they do some protection configuration. 

The heavy lifting is done on the infrastructure side, but the other teams monitor, maintain, and most importantly, test it. This is a big deal because we previously had the infrastructure team do all the testing for us before Zerto. Now, the business unit managers directly in IT can do their own testing, which is a big change for us.

Their technical support is excellent. They have a great support portal, which is easy to use. They are very responsive and generally able to help us with any configuration or performance issues that we run into.

Our previous product was VMware Site Recovery Manager. We switched to get a less complex system that could protect our workloads better and enable faster recovery. Those were kind of the main reasons why we switched. 

The initial setup was straightforward.

We deployed Zerto initially with a VAR. They explained the process very well. It was just an initial installation service which included some training. Then, we took over the management of it and have been managing it in-house ever since.

We have seen ROI. The biggest way that we have seen it is in avoided downtime. We have had outages before, and we count downtime in terms of dollars spent. We have cut that down so dramatically, which provides us a very quick ROI. We have drastically reduced the amount of time it takes us to recover workloads, from an average of two hours to an average of 10 minutes.

We measure our downtime in thousands of dollars per minute. While it depends on what is down and who it is impacting, we take in an average of $1,000 a minute at a minimum. So, 120 minutes of downtime at $1,000 is $120,000 per workload that is down, and that can add up very quickly.

My only business complaint is the cost of the solution. I feel like the cost could be a tad lower, but we are willing to pay extra to get the Premium service.

Zerto does a per-workload licensing model, per-server. It is simple and straightforward, but it is not super flexible. It is kind of a one size fits all. They charge the same price for those workloads. I feel like they could have some flexible licensing option possibly based on criticality, just so we could protect less important work. I would love to protect every workload in my environment with Zerto, whether I really need it or not, but the cost is such that I really have to justify that protection. So, if we had some more flexibility, e.g., you could protect servers with a two-, three-, or four-hour RPO at a certain price point versus mission-critical every five minutes, then I would be interested in that.

The costs are the license and annual maintenance, which is the only other ongoing fee. I would imagine a lot of customers also have an initial project cost to get it implemented, if they choose to go that direction, like we did.

We do not currently use it for long-term retention. We have another solution for long-term backup retention, but we are in the second year of a three-year contract, so we will evaluate Zerto when those contracts are up. We will probably test it out. It is certainly something that we will look at. We will also plan to vet having backup and DR in one platform.

The incumbent was Site Recovery Manager, so we evaluated them as an incumbent. We also evaluated Veeam Disaster Recovery Orchestrator. We use Veeam for data backup, and they have a disaster recovery piece. It would have been an add-on to our Veeam, so we evaluated that while also looking at Zerto.

It would be ideal to integrate your backup and disaster recovery into a single solution, so that is a pro whichever way you go with it. Zerto certainly has an answer for that, but so did Veeam. Zerto's replication is superior to anyone else's out there. It's faster, simpler, and effective. I don't think I could get as low an RTO and RPO with any other solution other than Zerto.

When comparing this solution to Site Recovery Manager, pay special attention to the fact that Zerto is hypervisor-agnostic and hardware-agnostic. It is a true software-based solution, which gives flexible options in terms of the types of equipment that they can recover on and to. Ultimately, it is very flexible. It is the most flexible platform for system replication. 

I would definitely advise them to give Zerto a chance and PoC it, if they desire. It is the best solution in the marketplace currently and has maintained that for quite some time.

I would give them a nine (out of 10). I really love the solution. I want more Zerto, but I can't afford more Zerto. I would love to protect everything in our environment, but we do have to make a business decision to do that because there is a requisite cost.

We use the solution for two different data center sites. Inside the data centers we use VMware virtualization, NSX stretched VLANs and Dell servers. There are many servers, storage, virtualization, and a myriad of operating systems such as Red Hat and Windows Servers. 

We use Zerto to replicate our VMs from one site to the other, where we don't want to have to pay for two licenses of the same thing. We also do this to have high availability or to have the disaster recovery version of a piece of software. It is a benefit to be able to use Zerto to replicate that VM at the second site, and not have to power it on or anything. We know that it's always replicated on the other site. We currently use the solution for disaster recovery only but we are looking at longterm backup retention in the future.

I think it's perfect for providing continuous data protection for us, it is excellent. 

The most valuable feature is how simple it is to implement and how quickly you can get up and running at the second site. The solution is also extremely easy to use, for example, You just log onto the console and you can do a test failover with a few clicks. You can run a failover test for your auditors or your management. Afterwards, you can get a report on how easy it was to failover a specific application and the VMs associated with that application.

In future releases, doing backups of the environment we need to be able to do hot backups of the database. Granular based backups of the OS, versus taking a backup of the entire VMDK. Currently, I don't think we are able to do all that right now. Having an agent-based backup is a benefit because you can back up the OS files, and If you have an agent for the database, you can do a hot backup of the database and restore it. You then would have the ability to do an entire VMDK backup. I don't think that they have the ability to do a hot backup of a database itself via an agent or something similar.

I have been using this solution for four years.

We have a couple hundred people using the solution within the organization. The solution is very stable, you set it up and you can forget it. When we have had issues where we lost the connectivity to a data center, we were easily able to bring up the VMs of a data center that was available using Zerto.

It's very easy to add new hosts and the VRAs get to pull it out automatically. It's very easy to scale, at more sites. We are already increasing and adding more data centers that Zerto can protect for us. We are very pleased with it.

The customer service is stellar. They always answer and they are very helpful. I have had very good relationships with the sales executives and sales engineers. If the team at the technical support cannot get an issue solved, then our pre-sales engineers will get on calls with us and help us sort through problems. They have been great.

We were using SRM, VMware's Site Recovery Manager before we switched to Zerto. We did the switch because we were impressed with the demo that was given to us. Additionally, SRM was very complicated and cumbersome.

The setup was easy and demo replication was simple too. The initial process started by us building out the VMs of the virtual machines, as per their requirements. We deployed the manager, based on all the log information of the vCenter. You then select the data storage and it installs the VRA out on your environment. Once that is done, you put together the virtual protection groups and you build out your replication site, it is very easy.

Our deployment took about a month to go through everything with three different staff members and for the maintenance, we have one technician. Make sure that we grouped everything properly together, based on the network and its functions, and how it should be brought back up etc.

I have saved days and even weeks of working time from using the solution. We are in the process right now of designing a new cloud infrastructure for one of our environments to utilize Zerto to replicate our VMs to our cloud. It is going to be a huge time saver, probably saving us a couple hundred thousand dollars. We've definitely seen some good return on investment with it. Our auditors are impressed by it. 

This solution is far less expensive than SRM and NetBackup. After the standard licencing cost there is an annual support contract, nothing that we were shocked about.

We have also used NetBackup but Zerto was much easier to set up.

When trying to think of improvements I cannot think of anything to critiques at this time because it does behave so amazingly well. I've been involved with other SRM implementations and SRM is very complicated to put together and to configure, whereas Zerto is just so easy out of the box. Overall, the solution probably has saved us hundreds of thousands of dollars or maybe millions.

Some of the important lessons we have learned are you need to plan your DR carefully. That is the most important. Also, make sure that your applications are grouped together, be cognizant of the different virtual networks they go into. For example, If you have a web frontend DMZ that goes into one component, where the application and the database are in another place. You need to be careful on what networks you are sending them to at the replication site, be aware of that.

I highly recommend Zerto. I speak about the product all the time. I think that it is priceless what it does for us. 

I rate Zerto a ten out of ten.

We are using it for disaster recovery for our day-one applications that need to be up first, upon failover.

We previously had our Microsoft SQL Servers set up as clustered pairs, with the primary in one data center and the secondary in the other, and they were staying in sync via SQL Server Log shipping. That was not a very efficient way to get SQL servers failed over. There were also some things that weren't replicated through log shipping, such as the SQL Server Agent jobs that are defined on the server, or the custom permissions that are set up for the different roles. Zerto was able to replicate the entire server, including the jobs and the permissions, and eliminate the need for us to have that secondary server. We were able to break all of our SQL clusters and just have standalone SQL Servers. It helped to increase our efficiency with failover and reduced our overall compute and storage footprint around SQL by about 40 percent.

When failing back or moving workloads, the solution saves time and reduces the number of people involved. The time from the initiation of a failback to the completion is about five minutes for us. We've also made some tweaks in the DNS to help that to update and replicate quickly so that we're not waiting for that, even if the resource is available. As for the number of people involved, for SQL especially, it used to require getting the SQL team involved and they would do everything manually. Now, anybody can just click through the recovery wizard and perform the failover.

Our savings from Zerto are around licensing and how we structure our current environment. We were able to save money with our on-prem deployment, but we don't use it for cloud.

And in terms of downtime, every time we test a failover it's non impactful to operations, because we're able to do testing in an isolated environment. Before, if we wanted to test our failover processes it was going to create a production outage. That is no longer the case. Before, when we were doing regular DR tests, I would estimate the cost of the downtime to have been about one weekend per quarter. That's the time we would have to take to do that. Only if we were to do a live failover as a test, which would probably not be done more than once a year, would we really have to worry about impacting any operations.

The most valuable features would be the

• granular configuration of your SLAs
• built-in WAN compression as part of the replication 
• easy wizard-based failover.

The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively.

The replication piece with the built-in WAN compression is important because the network circuit that we send our replication traffic across isn't actually behind our normal WAN accelerators. We were able to use Zerto's built-in WAN acceleration to help those workloads compress.

The failover is important because that way I can delegate initiating a failover to other people without their having to be an expert in this particular product. It's easy enough to cross-train people.

Continuous data protection is Zerto's bread and butter. They do all of their protection through your journaling and that continuous protection gives you countless restore-point opportunities. That's extremely important for me because if one restore point doesn't work, because it is a crash-consistent restore point, you have so many others to choose from so that you really don't have to worry about having an app-consistent backup to recover from.

Zerto is also extremely easy to use, extremely easy to deploy, and extremely easy to update and maintain. The everyday utilization with the interface is very easy to navigate, and the way in which you perform testing and failover is very controlled and easy to understand.

The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover.

My other main inconvenience is fixed in version 8.5. That issue was moving virtual protection groups to other hosts, whenever a host goes into maintenance mode. That's actually automated in the newer version and I am looking forward to not having to do that any longer.

I've been using Zerto for coming up on four years.

My impression of its stability is very positive. It doesn't seem to have any issues recovering after you shut down any of the particular components of the application. It seems everything comes back up and comes back online well. 

Sometimes the replication appliances will stop functioning, for one reason or another, and most of the time a power cycle will resolve that. But anytime that I do have a sync issue, support will generally be back in touch with me within the first half hour after opening a ticket. They're very responsive.

The scalability is able to take on any size environment. We don't have a huge environment here. We only use it across 20 hosts, 10 at each site. They're very large hosts. If you have more than a certain number of virtual disks protected on a single replication appliance, the replication appliance will automatically make a clone of itself on that host to accommodate the additional virtual disks. It seems to be built to scale in any way that you need it to.

While our hosts are very large hosts, we don't have any current plans to extend that deployment because we have capacity to grow within our current infrastructure footprint, without having to add on resources.

I rate their technical support very highly. They're very responsive. Usually within the first 30 minutes of opening the case, someone has tried to reach out to me. I will just get a screen share, or a reply to my call with an answer, or a KB article. I have a very positive impression of their support.

We were using Site Recovery Manager for several years, and I always struggled with keeping that functioning and reliable. Every time something changed within the vCenter environment, Site Recovery Manager would tend to break. I wanted to switch to a DR product that I could rely on.

In addition to Site Recovery Manager, we were also using NetApp SnapMirror. We are still using that for our flat file data which is non VM-based. We have Rubrik as our backup solution because, while we replicate our backups, there's not any automation behind bringing those online in the other sites. So it's a manual process to do disaster recovery.

We were having to utilize those solutions to do the failovers for our day-one application in SQL and they were inefficient and ineffective for that. Zerto was able to come in and target those workloads that we needed better recovery time for, or where we needed a more aggressive replication schedule. Zerto is supplementing those other solutions.

Zerto is easier to use than the other solutions. There's definitely more automation and there are more seamless failover activities.

When I deployed the solution, it took certainly less than a day to get it up and running. The upgrade process has been fairly seamless and painless, in the past, as we have gone from one version to the next. That includes some of the features they've enhanced, where it automatically updates the replication appliances as well as the management pieces.

We have two data centers and they're both Active-Active for one another. Our deployment strategy for Zerto was to stand up a site server at each one, pair them together, and then start identifying the first workloads to add into Zerto protection. We started with our SQL environment. 

I was the only one involved in the deployment. If I had questions I would ask my account team. My sales engineer and the account rep are both very knowledgeable. But I actually didn't need to open a support ticket as part of the deployment. It was very easy and straightforward.

About five of us utilize Zerto. I am the infrastructure engineer, focusing on the compute side of the house. We've got a storage engineer. My manager is an applications delivery manager who uses it. We've got another senior network engineer who focuses more on the runbook side of things, and he uses it. And my backup, who is our Citrix guy, is starting to use it.

Zerto doesn't really require any particular care and feeding. Whenever a new version comes out that has features sets, I'll decide when I'm going to update it and do that myself. It doesn't really even require a support call. It's pretty straightforward. For each management appliance, updates have taken 10 to 15 minutes, in the past. And it's just a couple of minutes for each replication appliance.

Our ROI is quite significant. The SQL cost savings alone would be in the hundreds of thousands of dollars per year. That's due to the fact that we don't need to have our SQL clustering set up as an always-on cluster, which would need to be a higher tier of Microsoft licensing. We're able to use SQL standard for everything, and that wouldn't be possible without a third-party like Zerto to do the replication and failover.

Get the Enterprise Cloud license because it's the most flexible, and the pricing should come in around $1,000 per VM.

Support is an additional cost. We are currently doing three years of support. There's an additional 15 or 20 percent of overhead during each year of additional support for each license.

Definitely take the free trial and put it through its paces, because you really can't break anything with it, given the way that you can do the testing. It gives you a good opportunity to play with the tools without having to worry about causing any problems in the environment.

We have plans to evaluate the solution for long-term retention. I'm going to start testing some of their features once we upgrade to version 8.5, and then we'll evaluate if it makes sense to do that or not. We do have other backup products that we're evaluating alongside of that though.

The solution has not reduced the number of staff involved in overall backup and DR management. We already run a very lean engineering team.

I got what I expected. I'd actually been trying to bring the product in since 2014 but I kept not getting budget funding for it. I feel satisfied with what I ended up with and I'm glad that we were able to move forward with the project.

It's on-prem only, and we're replicating part of production data centers to the DR location. We use it 100 percent for DR. Zerto, as a product, has a lot of capabilities, but we're only using it to replicate servers for disaster recovery, on-prem.

Providing DR for the entire organization is a big improvement, compared to the previous way we did DR. With the old DR tool we identified the systems that we wanted to protect and we installed agents and installed a server in the remote location and pretty much treated every physical and virtual server the same way. That tool was agent-based and required installation and maintenance of a server on the remote site. Now, the effort involved is a fraction of what it was before. We just click the VMs that we want to protect and they are protected.

Zerto has reduced the number of staff involved in DR.

It has also helped to reduce downtime. With our old solution, something that took 10 to 15 minutes of outage, required one reboot, which took less than a minute, with Zerto. That amount of downtime would have cost our company a couple of thousand dollars.

Zerto's support for different hypervisors is a valuable feature because we have a mixed bag. We have VMware and we have Hyper-V. For us, that was extremely critical when we made the decision. We wanted a single tool that is able to replicate all our virtual servers. At this point, I think the only tool on the market that can do that on-premise is Zerto.

It does a great job of continuous data protection. That's why we're using it for DR. It has the journal, the recovery points. It's doing its job. It's a good tool.

It's extremely easy to use with a very intuitive interface. You can set up a VPG (virtual protected group) and add VMs to it in a couple of clicks. Everything is in a single dashboard and you can do everything from there. If you need some granular information, you click the Analytics and get your RPO or RTO and how much data you would lose if you do a DR at this point in time. 

They definitely have room for improvement in a couple of areas. One is role-based access control. Right now, they don't have an identity source so they use the identity of the vCenter or the VMM. If they connected to an identity source like Active Directory and allowed for granular roles and permissions, that would be an improvement.

Another area of improvement is support for clusters. They have very limited support for Microsoft clustering.

Also, integration with VMware could be improved. For example, when a VM is created in vCenter, it would be helpful to be able to identify the VM, by tags or any other means, as needing DR protection. And then Zerto should be able to automatically add the VM to a VPG. 

There is definitely room for improvement. But what they have implemented so far, works pretty well.

I have been using Zerto for about five years.

It's pretty stable. 

We're always one version behind. The current version is 8.5 and we're running 8. We always wait until at least Update 1 before we upgrade. So when v9 is out, we'll probably upgrade to 8.5, Update 1, or whatever the current update is. Because we are a little bit behind and we're running on a very stable, mature version, we rarely experience issues.

We're running thousands of hosts. Scalability is not a problem.

We plan to keep the product. It's doing a good job.

Our experience with their technical support has been good. But keep in mind that we have a pretty high-level, Premium Support agreement with Zerto. We have a dedicated technical account manager from Zerto, and he has direct access to the developers.

We used Double-Take DR which treated all the physical and virtual servers exactly the same way with agents. Zerto replaced it.

We switched because it is a little bit inefficient to treat all the virtual machines as separate physical servers, because on the DR site you need to install them, you need to configure them. You need to put the agents on both sites and configure the replication relationship. It's very complex. And whenever you need to patch or do some maintenance on the target site, it's double the work because you patch the source and you patch the target—you have a live server at the remote site. With Zerto, as soon as I patch the VM at the source, the updates are replicated to the target immediately.

Zerto's ease of use is very good compared with other similar solutions for replication.

The initial setup of Zerto is quite simple. You build a SQL instance. You build a Windows VM and install the ZVM on it. You integrate it with vCenter and then, from the ZVM, you make sure your firewall ports are open and you push the VRAs down.

Deployment takes a couple of hours, for a relatively big environment. It would typically require 30 minutes of DBA time, an hour or two of Windows engineering time, and another person from VMware for another hour.

It doesn't require any staff for day-to-day maintenance. It's used by our operations team, which is close to 100 people; those are people who have access to it.

It's quite easy and straightforward. We do it with internal labor.

The way we use it there is no return on investment. You can think of Zerto as an insurance policy. We use it to protect our business, but we actually hope that we'll never put it into action.

It's not the cheapest tool, it's expensive. But it's doing a good job.

We pay the standard license, maintenance every year, and we pay for our technical account manager, which is pretty much Professional Services, with our Premium Support.

We looked at other solutions. We own another solution called VMware Site Recovery Manager, SRM. We have licenses for our entire environment and we still decided not to use it. That's how big the difference was in the experience that Zerto provides. 

We also compared Zerto with our previous disaster recovery solution, which was called Double-Take DR.

Zerto is much better. It is not a cheap solution. The fact that we decided to buy it when we already had all the licenses for VMware, bundled in our ELA with VMware, should tell you how big of a difference there was.

My advice would be that when you need a tool to bet your business on, as a last resort, make sure you evaluate all the options, test them, and don't be cheap.

The biggest lesson I've learned from using Zerto is that a third-party company can do a better job of protecting the workloads than the vendor. It does a better job than VMware and Microsoft together.

In terms of using the solution for long-term retention, we're evaluating Zerto's offering. It's a new feature. We already have an established backup system, using Symantec. In a couple of years, when we need to refresh Symantec, we might consider it. But at this point we don't use it and we aren't considering it.

We use the Veritas NetBackup solution. They split from Symantec so Veritas is separate, but it was a Symantec solution for backup. We don't use Veeam, we don't use Cohesity, we don't use Rubrik. The only potential is to replace our Veritas/Symantec backup product, in the future, with Zerto Long Term Retention.

If we have a DR situation, we are not planning to fail back. It's not part of our DR strategy. If we need to fail-over a production data center, it means that this data center has been destroyed, it's a smoking hole in the grass. We will be running continuously from the DR data center, which is a full-scale data center.

I would rate Zerto at nine out of 10. There are new features that they're working on, which will be nice to have. That's why I won't rate it a 10, but overall it's a really good, stable, easy-to-use product.

We needed Zerto in order to provide a disaster recovery solution for the entire organization. We use it to replicate some resources on-prem and for quick recovery. We also use Azure to replicate for disaster. If we ever have a catastrophic failure or attack at our main headquarters, we could failover and run our resources in Azure. 

We don't use Zerto for backup, we use Veeam. Once the new long-term retention features are added to Zerto, then we will investigate using it for that and possibly dropping Veeam.

There wasn't anything in place that compares to what we're getting from Zerto. Before Zerto, we didn't have a proper disaster recovery program or application in place. We had a simple backup solution where we could back up our data every 24 hours. So we went from that to being able to recover full systems within a matter of minutes. With Zerto, if we do have an event or disaster, we know that we can recover from that much quicker than we were able to before.

We use Veeam Backup for data and not for replication so this is purely just for disaster recovery and replication. We don't use it for data backup, we're still using Veeam for that.

Zerto definitely decreases the time and people it takes when we need to failback or move workloads. The benefit of using it with the Cloud is that we don't have to maintain extra hard work or an extra infrastructure for disaster recovery. With Zerto and Azure, it can all be done essentially by one person. If we're restoring data and systems from the cloud, it can all be controlled from the Zerto interface, whether it's on-premise or in the Cloud. To move the data back, depending on the size of the disaster, if we were to have to rebuild our hardware on-premise, that would obviously require more people. But if it's just a matter of restoring data from the Cloud, it would only need one person. Whereas before, you could probably still do it with one person, but the amount of time that would take would be a lot longer. We would have had to rebuild servers to restore the data. With Zerto, we can restore entire servers from our Cloud repository and have them up and running, it would just be dependent on the speed of the internet. Zerto could easily save us days of time.

It saves us time in data recovery situations due to ransomware. If we had a ransomware attack, we could have our systems available for investigation and run our environment entirely in Azure, separate from our on-prem network. With Zerto as well, we could also recover our systems to the point in time before the ransomware attack happened, ensuring that it doesn't happen again. With our resources in the Cloud, we can scan it for infections and pull it out if it's been lying dormant. The big benefit against ransomware is that we can easily just go back in time to the point before the attack.

The ability to do DR in the Cloud rather than in a physical data center has enabled us to save money. It has saved us quite a bit of money by utilizing Cloud resources, instead of buying a whole new recovery site on-premise. We did an analysis of the buy and one of the reasons why we went with Zerto on Azure is because of the amount of money that we would save over a five-year period. Based on our analysis, it saved us roughly $25,000 a year.

The one-click failover feature is very valuable because of the ease of use as well as the little to no data loss with the constant replication in journaling technologies that it has.

The one-click failover feature is really valuable to us because we need a solution that's easy to use. There's the potential that myself or other staff may not be available at the point of the disaster and it would be possible to have somebody who may not know the technology be able to initiate a failover on our behalf by simply just asking them to click a button.

The important features of having little to no loss of data are extra valuable because if we do have a failover event or an event where we need to initiate a failover for disaster, having no data loss is really important because if we were to have a disaster where we needed to initiate the failover for recovery, and if there was data loss, that's lost time from staff. It's also really hard to tell what data is lost and what has to be made up. We have certain resources here that can't afford any sort of downtime or loss of data.

Its journaling technologies are always sending replicated data up so that we can view what the recovery point objectives would be in real-time. We can see it could be a matter of six seconds to a couple of minutes, and that gives us peace of mind that things are moving constantly so that when we do have a failure, we can go back to pretty much any point in time that we want and have our systems available again.

Zerto is very easy to use, the interface makes it really easy. The wizards that are available, the how-to guides, and the support from Zerto has made it really easy to use. With little to no training, we were able to get it up and running in the test environment in under a day. The interface makes it really easy to use from using it from day to day, setting up new jobs for replications, or even restoring data.

Long-term retention of files is a function that isn't available yet that I'm looking forward to them providing. The long-term retention is the only other thing that I think needs improvement.

We have been using Zerto for around nine months. 

Zerto is very stable, we have not had any issues with it so far.

Scalability is fantastic. It can go from a very small number of machines up to a very large number of machines without any issue. We started small and they included more and more to it and I haven't had any issues. We have not had any problems scaling across sites to other sites within the organization and integrating it all together. It's as advertised that it can be in any environment of any size. It scales very well.

Only one or two people are required for the maintenance of this solution. As the manager of technology and infrastructure, I and the system administrators do the maintenance. I mostly work with it. One of my other staff works with it from time to time, but for the most part, it just does its thing and we don't really need to do a whole lot with it.

Zerto is used extensively in my company in the sense that it is our primary disaster recovery solution. It is used for servers throughout the County for all departments. Every system that we have in place relies on Zerto for DR. As servers increase, we will add those servers to Zerto, for disaster recovery purposes. It's completely integrated into our system.

Zerto hasn't reduced the number of staff involved in overall backup and DR management only because we have a small team to begin with. Our infrastructure team that I'm in charge of is only six staff. So DR and backup is one job amongst many, for all the staff here. The amount of time dedicated hasn't changed a whole lot for us.

Their support is fantastic. Anytime we've had an issue, which has been not too many, they've been very good to resolve any issues.

We also use Veeam and it is really easy to use too. They're both easy programs to use. If anyone can use Veeam, they can use Zerto. I wouldn't say Zerto's any easier or Veeam's any harder. They do different things; Veeam does back up really well. If you need a backup solution, Veeam is far cheaper. Whereas Zerto is fantastic at disaster recovery and replication, but when it comes to backup, that's not really what it's made for. Moving forward that may change. But Zerto is definitely a much costlier program compared to Veeam but it does a lot more.

Zerto itself was straightforward to set up. There was good documentation available and we utilized some of their engineering services to help set up as well. For the size of the products and the complexity that it can do, the actual setup and operations over this are quite easy. It took a couple of days, which included getting everything in Azure set up properly.

The implementation strategy that we did was to create the on-premise environment for a dedicated network, virtual machines, and the installation. Then Azure would become our disaster recovery site in the event that we needed it if we had a disaster on-premise, we could failover all of our services and servers that we needed to in Azure. Then our client computers would connect to them while in the Cloud while be prepared for recovery on-premise.

We utilized a third-party consultant to assist with setting up our Azure environments and Zerto technicians helped us set up Zerto on Azure. Our experience was really good. There were some challenges and there was lots of learning to do, but overall, the experience was good. The staff from Zerto were exceptionally good. They really know the product well, helped quite a bit, and provided instructions and training on how to use it outside of that.

I think that return on investment will come in the event that we do have a disaster that we need to recover from. We have seen some ROI from Zerto by moving virtual machines between data centers, where that has saved us a lot of time. The technology not only is useful for disaster recovery, but also for server maintenance and moving resources between posts and impairments. Before, it could take hours to copy virtual machines, even days. We use Zerto to move resources around with little to no downtime in a lot quicker time. So we were able to save staff time and resources by using Zerto.

It wouldn't have cost us too much with the government. It's hard to equate a lot of downtime to dollars and cents for us because it's more so around staff time and convenience. We have long-term care homes that we need that are up all the time. And any of those maintenance windows we usually schedule after hours. So it's more of an inconvenience for IT staff to work overnight instead of during regular business hours.

Zerto is not cheap; however, it is worth the cost. The licensing model is easy. You buy based on the amount of virtual machines you want to protect and go from there. Even though it is not a cheap program, you do get what you pay for, but overall it became cheaper than maintaining a separate data center.

We looked at Cohesity, Rubrik, and Commvault. Veeam does replication as well, but it doesn't do it nearly as well. We looked at a few other solutions from Dell. We went with Zerto because it had all the disaster recovery functions that we needed, the ability to recover within minutes with minimal to no data loss, and is integrated well with Azure.

I would recommend doing the free proof of concept exercise with Zerto pre-sales engineers and work with them to discuss your environment and then review their recommendations on implementation. From time to time do the free training. I highly recommend doing that. Get your hands on this software and try it out first before doing the production implementation.

The biggest lesson I have learned is that disaster recovery doesn't have to be hard.

I would rate Zerto a ten out of ten. I don't rate many things ten, but Zerto offered me exactly what they're upfront with, what it will do, and it's doing exactly what they said it would do.

We use Zerto for DR purposes, we replicate what's critical to continue business. We replicate it from our headquarters to another state, a DR site. If something happens to the headquarters where we are located we could run the continued business from the DR site with Zerto.

It improved the way we function because we know that in the event of a disaster, we can easily recover our state of being in a rather quick amount of time. If there's malware, for example, we can go back to a point in time, up to five seconds before the malware started, and start production from that point on, undoing all the damage that the malware did. The ability to do that is a very good feature. It has replication and DR, but at the same time, if something happens with malware and it compromised your backups and compromised your offsite remote copies, you have that third option of saying, "We'll go to Zerto and see if we can reverse back from that point." That's pretty comforting.

If we need to fail back on work we would absolutely use Zerto for that. We'd probably do that first before we tried the backups. It's easier to do that than to try to look for the backups. 

Zerto decreases the amount of time spent trying to get everything back online. That's the most important part. If something happened, I could just go back. It would take me around 15 minutes to locate something and launch it fairly quickly. If you're doing it from a backup, you're probably going to look for a good backup, launch it, then it's got to set up. So you're looking at an hour, maybe, if you're lucky. It's a big difference.

We once had a server and there was some software and one of the controllers in the software wouldn't boot up and we did not have a copy. It was a brand new server, so we didn't have a backup copy of it just yet. We used Zerto to go back. It was in Zerto, but it wasn't on backups yet. We were replicating it just in case and we used that to restore the server back. I called support who walked me through it fairly quickly. The whole thing took around 15 to 20 minutes. It was easy. If we had used a different solution, it would have taken us an hour or maybe two. We would have needed to find the backup and then mount it. We would then launch code or a bunch of series of Wizards. Zerto is always running so if we need to get something, we just highlight, and then we go to more, and whatever we want to do, it's right there. We don't have to turn it on. We don't have to get it going. It's always running. Backups are in a stopped state, so we would have to get it going first, then look for something, then mount it, and then do whatever we're going to do. There are four steps there, versus with Zerto where it's, "Oh, it's in this VPG," go to more, it gives you all the actions you could do, clone, delete, copy and you just do it.

Zerto has reduced the number of staff involved in data recovery because it's only two people who manage the Zerto platform. It's mostly me. I do about 80% to 90% and then 10% is my supervisor. He's more into the meetings anyway. We require two people.

The replication is the most valuable feature. It's almost like a tape recorder. You can rewind if you need to, if something bad happens. You can rewind the tape and your production begins where your tape left off. Where you want it can be replayed for such a purpose.

Zerto is very good at providing continuous data protection. For replication purposes, it's definitely better than Veeam. Veeam doesn't do as good a job as Zerto does when it comes to replication. The other alternative would be to just have backups somewhere. But even with backups, you lose a lot of time because you have to set it all up. With Zerto, you failover, you just click a couple of buttons and you run from the other location.

It's very easy to use. Every morning I go into the dashboard and I can tell the health of the VPG groups. If there's a problem or anything, I'll see it in the active alerts. So the dashboard is pretty simple. There's a status that tells you if the RPOs are falling behind, or from what you set it to, there's a reminder that tells you when to do the failover test. I like that. If I'm going to add a server to a VPG, I just go to the VPG section of the menu, find our group, select it, and then edit it, go to VMs, and there it is. It gives it to me side by side. It tells me what is unprotected on the left, and then this is protected on the right. I can move from unprotected state to protected state or I can remove something that's in a protected state to an unprotected state. It always tells me at the dashboard from the bottom, how many licenses I have, and how many I'm using. I don't go over my license count where I might not be protected. It's pretty easy.

We've never had a situation where we had to go to Zerto for downtime. It's just protection, but we haven't had the situation where we've had to failover. Hopefully, we never do. It's like car insurance. You want car insurance, but you don't want to get into an accident.

The improvement that I would like to see is a little bit easier product knowledge, things like that. It's getting a lot better than it was before because it's not as old of a product as Cisco, but if you look for something like Cisco routing and networking, you'll find millions of articles out there and it's everywhere. It's prolific. So with Zerto, you have to find it within the Zerto application. Hopefully, as they grow, it'll be more out there on the net. Same thing with Microsoft. If you look for a problem with Microsoft, you're going to find millions of articles on it, maybe it's just because they've just been around for so long. I'm hoping that one day Zerto is just as prolific and can be found everywhere.

I have been using Zerto for two years. 

Zerto is very stable. There are very few errors. I just don't see any errors. The only one time we had an issue with it was with journals. We were filling up too much and we called support and they walked us through it. We found out that we were replicating a temporary drive and it's not good practice to back up temporary drives because they constantly change when it's not even necessary. So we removed the temporary drives and we never had that problem again.

I'm a system administrator.

If you were doing recovery from a backup, you'd probably want at least two people looking through backups quickly to speed up locating them. You might need somebody to set up a mount server to mount the backups on. You can get away with three people but you might need three depending on how urgently you want to get going. It depends.

For DR management, if I was with another solution I would require more people. If you have a Dell EMC, they have storage administrators that that's all they do. And so that's a dedicated position. I'm a system administrator, which means that I do the storage, I deal with the servers. It allows me to do a lot of things, not just one thing.

Scalability is excellent. We have one here, we have the one there. I know we could add another ZVM, another location, or another DR site if we wanted to. That's been in the talks for a long time. It's on pause now because of COVID-19. But if at some point we decide that we want to add a secondary DR site that is geographically opposed to where we are now, then we could replicate one, two, and three at the same time. It's got good potential to be increased.

We have about 20 to 50 servers in Maryland and we replicate all the critical, essential ones that would be required to continue to run business to North Carolina. Everything is virtual, which helps us out. We have one Zerto virtual manager here, we have a Zerto virtual manager in North Carolina, and we do failover every six months just to make sure that it works. As a matter of fact, we have a failover test coming up that we have a test of failover to make sure that it's continuing to work.

The support is very good. I've used them before. When we had the journal issues, it was easy to resolve the issue.  We've done upgrades on the versions and they've always been very responsive. If I do a P1, which is critical or they do a P4, which is just information, they respond fairly quickly. 

We've used Veeam for backup. Before Veeam, we used Unitrends, which is even worse. It didn't work. 

Zerto's good for DR replication. I don't think anybody does it better. Veeam is good for short-term backups. It doesn't do well with the replication part at all - even they say it. I've spoken to reps who agree and say that Zerto's better at it than they are.

The initial setup was pretty straightforward. You set up a ZVM here and there and tell it the direction you want it to replicate in to. You can create an EPG to the journal that goes attached.

Because we were setting it up in the middle of things, it took around one month. 

We did have a strategy of how to put those servers here, build servers there, and IP addresses we were going to assign to it. We did have some sense of where we were going to put things.

We used the reseller who helped us with the deployment. They were great. It was easy. No problems with it.

We bought it through CTI.

I think we do see ROI. We need a defensive posture to protect ourselves.

Pricing is okay. You don't use Zerto to put all of your servers in Zerto. The purpose of it is you take what is absolutely critical to continue running your business, whatever servers are in your business continuity plan. Those are the ones that you put in Zerto. Then you'll be fine in the licensing because if you just buy 200 licenses or 300 licenses and you're backing up a utility server or any server that's not essential, then your bosses are going to think you're spending too much money. But if you just zero in on what's critical and back that up with licensing, you'll be fine.

There are no additional costs that I'm aware of. We have the licensing fees that come up and then that's it, as far as I know.

We had a couple of proposals. We had the one from Veeam but we realized really quickly that it doesn't work for replication. The other alternative would have been to save the backups to the offsite location, have servers there, and load backups at the server location. That takes a lot of manual labor so we decided Zerto would the best option.

We don't know what we're going to do for long-term retention. We use it for DR purposes only. But we are still looking at the long-term retention and what to do with it.

I would say if you're looking for true DR protection with minimal recovery time, then Zerto is probably going to be the one. If the objective is minimum time to recover, then this is the product you need to buy. If you want to spend time trying to set up again in a disaster, then there are a lot of things out there and for ransomware too. We have about a five-minute window where once data is compromised beyond five minutes, it's useless. So we need to keep the window to about five minutes. Because of that, Zerto is really going to have to do that at this point in a cost-effective way to recover. 

I like Zerto. You learn different things as you use it more and more, so you become more competent with it as you use it. I know that if you do have an issue, as with most other vendors, the easiest solution is to provide the logs as soon as you can, and then they're better prepared to respond if you do it that way.

I would rate Zerto a nine out of ten. Nothing is perfect. 

We use it for DR as well as migration. We have four data centers and migrate workloads between them.

We don't use it for backup.

We had some ransomware that got on and infected the corporate shared drives. It was just one system and one user type of thing. It didn't spread because we had it locked down pretty well. So, I just bumped the server back entirely so we did not have to worry about it.

We have only had one instance, and it wasn't widespread, where we had ransomware. The RPO was approximately 20 minutes. We had an active snapshot from when the incident happened, because we couldn't really iron it down. Therefore, Zerto saved us time in this data recovery situation because I didn't have to rebuild the thing or do a SnapMirror. 

If we had used a different solution, it might have taken a week for our data recovery situation instead of 20 minutes with four or five technical folks (not including management), instead of just me. This is because we didn't have anything documented and just counted on Zerto to do it. I don't know what the company had set up previously since I'm new, but at the previous place that I've experienced malware, you would have to stand everything up from scratch and scrape through all your backups and differentials. 

We use in the data center if there is a live event that could cost the company millions of dollars, which I haven't experienced, e.g., if our data center were to explode or get hit with a meteor, then ceases to exist. We have the option to go in and flip a switch. That has never happened. However, our tests using SRM went from a day to minutes when we switched to Zerto.

The most valuable feature is DR. In my opinion, there is nothing better at what it does.

The solution provides fantastic continuous data protection. We do a lot of spin up test environments depending on what happened, then make changes and rip it down. Or, if we got hit with malware, then we use that to do a point-in-time recovery. We custom create software in-house, so we will spin up a test environment to test code deployments or do a copy to do the same thing, if we want it to be around longer than a test recovery. For example, somebody got hit with something, then they infected the server. We were able to restore it back to a point in time before the infection. 

It is super easy to use. A non-technical user can get it up in a day. I can get it up in 15 minutes. I've brought it to help desk guys and network operations center guys, and it's easily grasped.

While I am open to transitioning over to using Zerto for long-term retention, the problem is the alerting function in Zerto is very poor. That makes it a difficult use case to transition over.

The alerting has room for improvement as it is the biggest pain point with the software. It is so bad. It is just general alerting on or off. There are so many emails all the time. You have no control over it, which is terrible. It is the worst part of the entire application. I have voiced this to Zerto hundreds of times for things like feature changes. Apparently, it's coming, but there is nothing concrete as to when you can do it.

Four years.

The stability is fantastic. It has gotten a lot better as far as the maintenance. Initially, it required a lot of prodding and poking. As it sits today, it is really stable, though you sometimes need to mirror the changes in the application to what you have changed in your own infrastructure.

The management once it is already deployed is easy to moderate. Things can get a little goofy with the DRS and if you're shuffling things around. If your infrastructure is pretty static, you're not going to have any problems with Zerto. But, if you move things around or do any updates, you have to come in and make sure everything is good to go. It is not difficult, but sometimes you are required to go in and maintain it. Because we turn off the alerting in most places, you don't know its status without going in and manually looking.

I am the primary Zerto administrator. Therefore, I own the product for my company and use it every day.

Scalability is great. It will scale essentially one-to-one with your virtual infrastructure. However, if you have more hosts and VMs, then you have to go in and manage that many more hosts and VMs.

Four people know it and use it to do things. I'm the primary, then there is another guy who is the direct backup on my team. Then I have trained a couple other people who know how to utilize it in the event of an emergency, e.g., "This is how you would failover X environment." Because it won't automatically do failovers, somebody has to pull the trigger. Therefore, we have documentation in order to do that. It is very simple.

We don't use it for everything, not in both instances where I implemented it or been in charge of running it over. However, it definitely has freed people up to do other things in that space. It only takes me to entirely administer Zerto, instead of a backup and recovery operations team with two or three people.

We are at about 60 percent of use. I would like to see more. We don't do persistent long-term backups or use any of the cloud functionality, though I think we will as we're in the midst of looking at AWS to potentially migrate workloads there. I also very interested in using it as cold storage.

Initially, years ago, the technical support was very poor. We were promised one thing that was physically impossible with the software. I spent a lot of time fighting everybody in support. Since then, the support has been really good. In my experience, they are all mostly stateside. They understand the product inside and out to help you with your needs or come up with some type of creative solution.

At my previous company, we were using SRM and our DR tests would take one to two days. For our primary customer, we switched to Zerto, then it took 15 to 20 minutes instead of days. It was a huge difference. That was from Boise to North Carolina, then back. It was approximately 30 terabytes of data with 19 virtual machines. It was a pretty large orchestration.

SRM was replaced by Zerto due to simplicity. SRM is very complicated. It is also not easy to use and set up. Zerto is better for implementation and ease of use. So, it was a no-brainer.

The initial setup was straightforward, though it could be more straightforward. Now, you just install the software on a Windows system. It would be nice if they had an appliance that autodeployed in VMware. That would make it simple. But if you can install Office or any kind of application on Windows, you can do this. It is super easy to set up with minimal front-end learning required. 

The deployment takes about an hour for an experienced person. If it is your first time, then it will take a couple hours.

You need to know your use case for an instance where you need something to be backed up. Once that need is identified, you need to know where it is and where you want it to go. Once you already have those questions answered, the implementation is simple. Through the installation progress, you just plug in those values of where is it, what is it, and where do you want it to go, then you're done.

At the company I'm with now and at my previous company, I was the architect and implementer. Zerto generally requires one person for the setup.

The RTO and RPO are unparalleled. In the event you do have an issue, you can be back up and running (depending on the size of your infrastructure) within minutes. Your RTO can be 15 minutes and data loss be five minutes. I don't think that's matched by anybody else in the field.

It has helped decrease the number of people involved in data center moves. For the infrastructure pieces, which is my primary responsibility, I am the sole person. Whereas, we use to have an OS guy and a network person before to manually configure the pieces. We also had application teams, but they are still relevant. Previously, it took four people because we were touching each environment and machine. Since we wanted it done fast, we would stack a bunch of people on it. Now, it's just me and it's done faster.

When migrating data centers, we have saved a lot of time on my team. Something that takes an hour or two used to take a week or two.

There is big ROI for ease of use, management, and labor overhead versus other solutions.

Zerto is more expensive than competitors, making the price difference pretty high. While it is very expensive, it's very powerful and good at what it does. The cost is why we are not leveraging it for everything in the organization. If it was dirt cheap, we would have LTR and DR on everything because it would just make sense to use it.

We currently use Veeam and Commvault.

In general, moving VMs through VMware using site-to-site is not as easy than with Zerto because the data has to go on flight, and Zerto just sends it over. I like that aspect of it. During our data center moves, we move from one location to another (San Jose) with a two-hour total downtime from start to finish: From powering the systems down, getting them over, getting a live feed changed, and back up and running to the world. This would be way slower with a different product.

For long-term retention, we do Veeam to spinning disk. While the LTR is something I am interested in, I think Veeam has the upper hand with alerting and job management. Both Veeam and Zerto are easy to use, but Zerto is easier to use.

I am not a big Commvault fan.

It could replace Veeam and Commvault, but not at its current price point.

Most people assume catastrophic failures have a long-term data impact. However, with Zerto, it doesn't have to be that way. If you spend the money to protect everything, you are going to get that low data recovery time. Whereas, if you are cheap and don't buy Zerto, it's going to be hours to days of data loss. With Zerto, it is in the minutes. Thus, how valuable is your data? That is where the cost justification comes in.

If you are thinking about implementing this type of solution:

• How important is your data? 
• Would your company go bankrupt if you were unable to do what your company does for a week? 
• Do you have contract requirements which say you need to have a DR plan up and running? 
• Do you want to spend a week doing it or 20 minutes doing it? 

It's that value of time, money, and data. I can implement Zerto and use it in an emergency situation anywhere. If you're talking to somebody like me who understands data protection and disaster recovery, the question is how much is your data worth to you and how fast do you need it back?

Currently, we are doing our own storage as the target for protection, but there is interest in enabling DR in the cloud, e.g., to do Glacier or something cheap in Azure.

I would rate this solution as an eight (out of 10).

We have servers in Houston and we have servers at a DR site, we need to be able to make sure that they're replicated in some form or fashion. That's what we use Zerto for, to replicate between our primary site and our DR site.

The biggest improvement for us was going from a possible 24-hour lag on our backups to real-time lag. With the hurricanes here in Houston, buildings losing power, and so on, it was nice having the ability to just go flip a switch and we're live with current data as opposed to we're live with what happened yesterday.

Zerto has helped to decrease the number of people involved when we need to failback workloads. It's a much smaller number. It's time-consuming because of the way it works, but it's not overly overbearing. Instead of taking a better part of the day or two to get everything up and running, it really only takes us three or four hours. It has also decreased the number of people we need. It would take three or four of us to bring up servers, make sure they're all running, test them, and all that stuff. Now, it takes one person to bring them all up and then there's a couple of us to test it, so we have half or less of what it used to take. 

We've never had a ransomware issue. The reasons for our failover has typically been natural disaster caused.

Pretty much all of the features are valuable. The biggest thing we use it for is replication, so the ability to set up our virtual server, set it to replicate, and Zerto handling everything else is the biggest feature that we like.

The continuous data protection is great. We love it because we can see exactly how many seconds behind real-time we are, which is usually under 10 seconds. It keeps things up to date. We love the product.

We currently don't use it for long-term retention. It's something we may look at in the future, but that's not the product we're using for that.

Zerto is very easy to use once everything's set up, which isn't difficult. It takes a little bit of time to make sure all the network stuff is all set up properly, but once everything's set up, using it day to day is very simple.

Zerto has saved us money by enabling us to do DR in the cloud rather than in a physical data center. Our DR is to a physical data center. We don't put our data in the cloud.

For what we got it for, it does it great. I use a different solution for my disk-to-disk local backups to where I can have a local backup of files. I don't think Zerto does that well to where it keeps a memory of the files that are there. Basically, when something is deleted on Zerto, it gets deleted on the replicated version. So, some sort of snapshotting or something where I could have backups at different points in time of files would be a really helpful tool.

We have been using Zerto for five years. 

Stability is great. The only downtime we have is during upgrades and patches. I really haven't had any problems with the platform or stability.

The time it takes to update or patch depends on the size of the patch. Major upgrades take a little bit longer, but I mean, it's typically a couple of hours at the most. It's not a huge thing.

Scalability has been great. It continues to grow as we grow. I haven't had any problems with it.

Zerto is being used 100% across our environment. 

We've got about 11 servers doing backups in the 20 to 25 terabyte range most of the time.

Only I work with Zerto in my company. 

The two times that we've contacted technical support, we didn't have any problems. They've been helpful. They made sure we got the issue resolved and did very well with it.

We previously used Veeam. We switched because of real-time backups. Veeam was a point-in-time backup. We said, "You're going to back up at this time." It took a snapshot and backed it up. Zerto just continually backs it up and makes sure that we're currently up to date and matching the server at your primary.

We use Zerto primarily for disaster recovery to the DR site. We still use Veeam for our backup disk-to-disk local for file backups.

Once Zerto is set up and running it is much more hands-off. You don't really have to do anything. You just log in to check, make sure everything's going well, and you're pretty much done. With Veeam, I feel like I have to check in a little bit more often, make sure the backups are running properly, making sure all the files are there, and everything like that. There is a little bit more checking to do on a regular basis.

I don't know if we would have failed over with Veeam because of the amount of time it took and coming back online at the primary site. I don't know that we would have failed over, which would have been probably five or six days of downtime. If we had failed over, we'd probably have lost two or three days in one direction, and probably another two or three days coming back to the primary.

The initial setup was pretty straightforward. It took a little while to make sure we had everything connected right, and that it was going to the right place, but it's no more difficult than any other setup for something like this. I didn't find it difficult at all.

If you don't include seeding and you only include the setup and deployment, it only took us a day or two of planning and then another day of actually implementing it. The seeding took a while, but that's to be expected.

In terms of our implementation strategy, we were using a different product back then, which wasn't as up to date and live. We were just backing up at night, so we had a nightly snapshot that was being transferred to our DR site. Our strategy with Zerto was to get us to more of a real-time backup solution at the DR site and make sure everything was good. That was the entire purpose of going with Zerto.

We used a third-party integrator for the deployment. We used Centre Technologies and they were great. We've used them for other stuff and we didn't have any problems with it and never have.

The one time we had the failover and run at the DR site, instead of having two or three days of downtime, we really had less than one day of downtime. If you measure that in how much money we were able to make that day, it's around $200,000 to $300,000.

We are on the lowest license because we don't exceed the number of servers for the base license, so I don't have a lot of information about licensing. The price of it was comparable, if not better than what we were paying for Veeam. I have no problem with the pricing at all.

There are no additional costs to the standard licensing. 

Make sure you know how long it's going to take to do your initial seeding. If you've got a lot of data, and you're doing it over a pretty good distance, just make sure your pipe is big enough for the initial seeding. Once the seeding's done, pipe size doesn't matter, but the initial seeding can take a good amount of time over a small-ish pipe if you're replicating a lot of data.

For our largest servers to seed can take a full week or to 10 days for one server, for our large file server to seed is about seven terabytes, but we don't have a huge pipe at our DR site. We negotiated to increase the pipe size temporarily while we were doing the seeding, and that reduced the time drastically on how long it took to seed. I can't really give a number or what to look for. I would just have that conversation with Zerto about how long a certain pipe is going to take. How long is it going to take to seed using whatever pipe size based on the amount of data that they have.

Make sure all of your notifications are set up well when it fails. It takes a little tweaking and making sure that everything is set up right, but when you want to make sure you're notified if you get outside your SLA on how long the backups are trailing, making sure all that's set up properly is key.

I would rate Zerto a nine out of ten. 

We do a semiannual disaster recovery test, usually one in January and another in September, where we fail our entire company over to our Arizona DR facility. We run the business out of the Arizona location for the day. In order to be able to do that, the Zerto application allows us to migrate 58 machines over to that location and allows us to run our business from that location for the course of the day.

We are able to have a successful disaster recovery solution through using Zerto for our Disaster Recovery drills. We are able to fail over anytime, day or night, to run our applications out of our Arizona facility. Within a 15 or 20 minute time frame, we can have those application servers up and running in Arizona. It is just a huge help to have a successful, reliable disaster recovery solution that we know at any point in time, within 15 or 20 minutes, can be running out of a different location.

Most of the time, this is at least a two person job. Previously, when we had a disaster recovery drill it would take two of us working for three or four hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I'm able to finish my work in about 30 mins and be available onsite to help and assist anybody else as needed during the disaster recovery drill. Its ease of use and the ability to have a reliable solution for disaster recovery has become invaluable to us.

There is built-in active logging if needed for a longer retention period. If we fail a machine over and are just doing tests for it, we can fail it right back at the end of the failover without much issue. We couldn't do that with SRM. The ability to keep track within the activity log of what is going on with the VM, then fail it back prior to the one-hour time frame that we have set up without having to worry about it losing data during our tests or production failover drills.

The product is very easy to use. On a scale of one to 10, I'd say it's a nine as far as ease of use goes. In order to do an update in our old product (SRM), we basically had to take down almost our entire vCenter to be able to do the updates. Whereas, I can do updates to our Zerto product within 30 minutes to both our ZVMs in Massachusetts and Arizona. We haven't had problems troubleshooting after doing upgrades. Within five minutes, we can configure a whole new cluster solution and work on getting it synced out to Arizona.

It transfers up-to-the-minute files. Therefore, if something was to happen and the business was to go down Massachusetts due to a server failure, we could simply fire up those VMs in Arizona within approximately five minutes. The data protection level is top-notch. We haven't lost any machines, data, or VMs during the course of utilizing this product.

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue.

Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available.

It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution.

Almost two years.

The stability is rock-solid. Nothing has gone down since we installed it; there has been no downtime.

Typically, once a quarter, we have an update. Last year we were at version 7.5, then we recently went updates to 8.0. On top of that, they release security patches and other things to improve bugs they find in the program. Right now, there is a U4 version that's out, which we will be updating to this quarter.

In the U4 version, there are security enhancements because a lot of zero-day issues that are being found in a lot of the applications. Zerto is making more security modifications and enhancements to the encryption between one location and another, so somebody can't hack your data and access it while it's in transition.

Scalability is very easy. We are going through a POC right now because we want to branch out to the cloud. Just getting that set up and going through the process was about 60 minutes.

It's very scalable and extendable. We can do one to many solutions, as far as where our disaster recovery is going. This is what we wanted. We would never have been able to do that with our SRM product.

There are two engineers trained to use the product. I'm the primary contact for the application and do most of the work on the product. One of the storage guys handles a lot of the storage set up on the back-end with me. We have at least two people trained on each application that we have in-house. Both of us are in charge of making sure the application is up-to-date and doing what it's supposed to be doing. 

Zerto's technical support is very good. They are very reliable and always very pleasant to deal with. We've never an issue working with them. They usually come back with the precise solution to whatever we are troubleshooting.

Our issues are usually user self-inflicted. E.g., we remove a host out of the cluster to upgrade it or do something else with it and don't follow the correct procedure that's needed in order to be able to shut down the Zerto appliance correctly. If somebody doesn't follow that procedure, because they either don't know how, weren't aware of it, or just skip that step, then it causes problems inside of Zerto. This will pause jobs and the VPG will no longer be accessible on that host. Sometimes it's easy to get it back up and running again. Usually, when you put a new piece of hardware in the cluster that has a different set of parameters with its hardware, then the appliance will be missing because it was taken out with the old hardware. Usually, you need to get their technical support involved in order to be able to troubleshoot the issue with them to be able to get the VPG back online again on the new hardware. As I said its self-inflicted most of the time because steps are missed with our processes.

The documentation that we got from them was in depth and work well when needed, if you follow them correctly you will have success. If you don't follow the steps, that's when problems develop. Therefore, it's not a fault in their documentation, it's a fault of the user who's not following the proper steps for success. It doesn't happen often but I think we have contacted technical support only three times in the two years that we've had the product.

For eight years prior to using Zerto we used to use a product called SRM, which is part of VMware. We finally switched over to Zerto after having them come in and do a presentation for us. This was after trying for about a year to do that and convince our vice president to allow us to migrate over to a different platform.

The reason why we used SRM was because SRM was built into our VMware vCenter licensing. We never had a successful DR test during the previous couple of years with SRM. By switching over to the Zerto product a year and a half ago, we were able to run a successful disaster recovery test within three months of switching over. We had our first successful disaster recovery tests in two and a half years because Zerto made our life so much easier and helped getting servers over to a new location almost seamlessly. 

In order to be able to have a successful disaster recovery, we need to be able to successfully migrate 58 servers from our Massachusetts location to Arizona. On previous attempts, we got about half the stuff over there, then we'd fail. In other scenarios we would get everything over there but some of the machines wouldn't come up because of the way they were configured. One time, the business was down for about half the morning because it took us that long to get the stuff back up and running using SRM. This was a real pain point for us, getting this product in place and working successfully. It took Zerto to be able to finally get us to do that. It's been a lifesaver. All we had with SRM was nothing but headaches.

The initial setup was very straightforward. We had everything running in half an hour. It got deployed with two virtual machines (ZVMs): One got deployed in Massachusetts and another in our Arizona location. From there, we deploy appliances to each one of the hosts that's inside of the clusters that we are managing for our disaster recovery solution.

Within 30 minutes, we had it deployed to our entire production cluster and the hosts in here. After that, we just started creating jobs, which took quite awhile to do because we have a lot of large servers. However, that's not the worry of the Zerto application, but the size of the VMs we have in production. 

For our implementation strategy, we just mimicked what we had in place for our SRM environment. Our 58 machines are spread across different clusters: some in our DMZ, some in our prod and some in our WebSphere clusters. After that, we ran two tests to ensure that we were able to fail over to our Arizona location then fail back without any changes or modifications to the VMs. Once we did that, we started rolling out to each of the clusters, one Virtual Protection Group (VPG) at a time. I think we now have 23 VPGs total.

We worked with an outside vendor (Daymark) who does a lot of our work through outside vendors. They work with Zerto directly. When we set it up originally, we had a Zerto technician on the call as well as a Daymark technician on-site working with us.

Our experience with Daymark has been very good. We love working with them and try to use them for our integration and infrastructure work. They are a very good company that are easy to deal with. We try to use them as much as we can. Thanks to Rick and Matt for a great working relationship.

We have seen huge ROI.

It used to be a three-person job, and now it only takes one person to manage and run the process. The fall back is the same thing. We've never had any issues with stuff coming back out of Arizona to our Massachusetts location. Within 15 to 20 minutes, we can have our servers successfully migrated back, then up and running just as they were originally without having too many conflicts or configuration issues. 

The solution has helped us reduce downtime in any situation that we have come across, thus far, for disaster recovery at a 4:1 ratio.

We are an insurance company therefore, if we're down for an hour, it's thousands of dollars being lost. E.g., people can't pay their insurance bills, open new policies or get the support they need for an accident.

These things have been invaluable to us:

• Not having to have so many bodies onsite during a disaster recovery drill.
• Not having to worry about multiple people dealing with the application.
• The product's reliability of always being up and running and not having any issues with it.
  

It's very equitable, otherwise we wouldn't do it. It's something that we utilize for the licenses per host used. Therefore, it's very cost-efficient as far as the licensing goes. For the amount of stuff that we have configured and what we're utilizing it for, the licensing is not very expensive at all.

There is a one-time cost for maintenance and support. We have a three-year contract that we will have to renew when those three years come up. There is also licensing on top of that for whatever product you are using it depending on the host configurations.

Right now, we use Veritas. We will be evaluating Veeam and Rubrik as a new solution for our backups in the next quarter or so, on top of the fact that we may decide to use Zerto. The three of them are in the mix right now for when we decide to switch over vendors for a better backup solution. 

Zerto gives you the ability to utilize it as a backup solution, but it's not a true backup solution because it can't do file level backups. If you want a particular file off of a server, it can't do that for you. What it can do is give you the whole server, then you need to go back and pull that file off it. Mainly for that reason, we haven't chosen to use Zerto and may never use Zerto as our backup solution. The other solutions allow us to get a file level backup.

Don't hesitate. Go out and do it now. Don't wait two years like we did. Push harder in order to be able to get the solution in place, especially since we know it will work better for you. Don't just take, "No," for an answer from senior management.

The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.

We don't plan to use the solution for long-term retention at this time, but we are looking at going into a hybrid cloud solution in the near future which we may be using long-term retention for to make a duplicate copy of everything we have in our Massachusetts data center into a cloud solution. Whether it be an Azure or Amazon location on the cloud.

While I can't really speak to whether it would allow us to do it, the application is set up to create a duplicate of the actual servers in Arizona. That's how it works so quickly. If we ever had a problem, I could always revert back from the duplicates that we have out in Arizona using the application, if necessary. Luckily, we haven't had a need for that, and hopefully never do.

I would rate this solution as a nine (out of 10).

We use Zerto for disaster recovery data replication from our headquarters to an offsite data center at another location.

It has replaced all of my legacy backup solutions.

The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location. So if we were to have a disaster, it takes about five seconds right now if I look at it. If we were to have a disaster, we would not only have current data, but we'd also be up and running within hours at our offsite data center, rather than days if we had a tape backup solution.

We have begun using it for longterm retention. We also replicate our file server. Our file server has archive or historical data that we have to restore occasionally. And restoring from long term retention is applicable to those types of scenarios, versus the streaming of the data, the real-time data. The longterm retention allows us to restore from further back in time. Real-time is more for recent changes to the data, and the longterm retention is for if we have to restore from further back.

It provides continuous data protection. It has been extremely effective. I've done failover testing, and the data is accurate and current. It works.

In terms of ease of use, Zerto is very intuitive. The graphical user interface of the application, both for monitoring VPG replication, longterm retention success, the configuration of VPG for longterm retention, and the analytics feature is intuitive and allows you to essentially analyze any changes to your environment. All of that requires some training but is not incredibly complex. It's presented in a very easy to use format. 

Zerto dramatically decreases the amount of time it takes to do a failover. I can essentially do it all by myself and I'm one person, I don't really need help. It allows me to restore our environment fully in a matter of seconds, literally. I can do that on my own from my desk very easily and with no outside help. 

Compared to other products, I would praise the intuitiveness of the product. But I think that can always be improved. The intuitiveness of the graphical user interface, while it is very solid and I don't have issues navigating it. I would say that it can always be improved.

I have been using Zerto for around three years. 

The stability is very solid. It just runs. It has not crashed or had issues. So long as you stay on top of the versions of the application and you have it installed on reliable hardware, you're going to be just fine.

It can scale into the cloud. I know it has that capability, but I have not done that yet.

It's essentially myself and I have one junior person that uses the application, but it's mostly myself.

It's used for all of our mission-critical servers. Not every single one of our servers, but probably about a third of our total servers.

I do not have plans to increase usage. 

The tech support is top-notch. I have an engineer who I work with on a regular basis that communicates with me anytime there is an issue. He has worked side by side with me on any issues, questions, and implementations that I have wanted to accomplish. They by far go above and beyond more than any of my other vendors and I have quite a few so that says a lot about them.

We previously used Asigra. We switched because of the cost, limitations, and complexity.

When we decided to go with Zerto, it was imperative that it provided both backup and DR in one platform. Granted, we didn't take advantage of it for a while but that's entirely my own fault. It was very important to have that functionality.

It was initially set up by a third party. But since then, I've had to re-set it up and it was pretty easy. It wasn't very complicated. It was quick. There were instructions that we followed pretty closely and there were no issues, so it was straightforward. There were a handful of steps, but nothing overly complex. The deployment took around 30 to 45 minutes. 

We haven't had a need to use it in an actual live disaster scenario, but we have that capability, which we did not before. But if we had to use it, it would save us a tremendous amount of money. Tremendous.

There are no costs in addition to the standard licensing fees. 

We also evaluated Veeam.

It has not saved us time in data recovery situation due to ransomware just because we thankfully haven't had any issues. I've done some testing and in those types of situations, it would be greatly beneficial. But I have not had any of those situations currently.

At this time it has not helped to reduce downtime in any situation.

We don't have it replicated in the cloud at this time so it has not saved use money by enabling us to do DR in the cloud, rather than in a physical data center.

I would recommend Zerto to anybody considering it. 

My advice would be to make sure that after implementing the product, go through and accomplish the training labs so you know how to use a product really well, develop a disaster recovery plan in the event that you should need to use the product, and work closely with your Zerto engineer to ensure that the implementation fits your business needs.

The biggest lesson I have learned is how valuable real-time replication of data can be in the event of a disaster and how valuable that functionality is in the event of a disaster. It has the potential to save the company many days' worth of lost business.

If I could rate it an 11 (out of 10), I would. But we'll go with 10.
