HPE Zerto Software Reviews

We are using it for disaster recovery. 

Zerto provides near-synchronous replication, but more importantly, we can see the status at seven seconds, six seconds, five seconds, and four seconds when we log in to the Zerto console. I found that amazing. There is probably no other disaster recovery solution available in the market that is providing this functionality. It is great and definitely a huge plus point for Zerto.

We do get alerts if suspicious activity is detected on a VPG, but we did not get an actual case where there was ransomware or any other kind of attack and we had to prevent that. I have not come across that with either of my clients, but we do get alerts when Zerto finds something suspicious. We go in and look at it. In some instances, because the application was writing more files, Zerto marked it as suspicious, but we never had to do recovery for security reasons.

We use Zerto with AWS as the target. We do the failover of the on-premises VMware virtual machines to the AWS cloud. I do not deal with the implementation. I only do the administration of the tool, but whatever I did as part of AWS administration in Zerto, it was pretty seamless and straightforward. I did not get any issues there. The documentation is helpful in identifying any issues.

We have about 70 virtual machines that are being protected by using Zerto. Zerto has drastically improved our RPO. It was 15 minutes previously, whereas now, it is in seconds.

Zerto has not had much impact on our RTO. RPO has changed, but RTO has been the same for us.

Zerto has not helped to reduce downtime in any situation. We have only done tests. We have not done any actual production failover because there was no need. Similarly, Zerto has not saved us any recovery time because we never had a requirement to do a recovery since we implemented the tool. It is a pretty new environment for us, so we have not had time.

Zerto has not reduced the number of staff involved in overall backup and DR management. It has remained the same for us.

The simplicity of use is valuable. It is easy. We just click Failover and do it. It is pretty straightforward. If someone wants to do a test failover, they log in to the console and do a test failover. 

As a power user, I find the customization lacking. I feel it could be customized a little bit more, but Zerto is simple to use. It is easy to use. That is my main reason for using Zerto.

I would like to request better reporting in Zerto. I can see the data that I need in the console, but if I need to put the data or the history into a report, it is difficult. It is something that auditors might require, so reporting is something that needs to be improved.

The UI does crash a lot, and that is something that can be improved.

It has been about a year. I support multiple clients with multiple backup and disaster recovery products. I was a Storage and Backup engineer, but now, I am covering the solutions for the entire infrastructure. I work on Zerto for multiple clients. We have two clients who are using Zerto as a disaster recovery solution.

The UI does crash, but it does not affect the functionality of the software.

It is scalable. There could be 10 machines or 100 machines. I did not find any issues. It is pretty scalable.

There were some issues for which we had to get responses from them. They were pretty much on the point. There were no issues. The response time was a bit slow, but their support was pretty good. I would rate them an eight out of ten.

Positive

We used to use Azure Site Recovery to protect all of the production instances, SAP databases, some file servers, and some basic application servers. We used to first replicate to Azure and then do a test failover and a production failover. It was a bit slow. The RPOs and RTOs were not that great, and the rate of change that Azure Site Recovery supported was not completely meeting the business requirements. The third part was that Azure Site Recovery was not application-agnostic. What we loved about Zerto was that it was application-agnostic. It did not matter to Zerto what was running behind the application. It will replicate everything across any cloud. That was our main point for going for Zerto.

Zerto was also much easier. Azure Site Recovery was a little bit hard to set up and maintain, but Zerto is pretty straightforward and easy.

I did not find much difference between Zerto and other solutions in terms of the speed of recovery. The RPO is great, but when we do a failover, it is basically the same as any other solution.

Zerto has not replaced our legacy backup solutions. Our legacy backup solution is in the same place. We are only using Zerto for DR.

Our environment is hybrid. We are using Zerto to protect our on-prem as well as the cloud environment, but I was not involved in its deployment. 

In terms of maintenance, I never had any requirements to maintain it.

Evaluation was done by someone else in the organization.

I would rate Zerto an eight out of ten. Simplicity is an advantage, but customization and reporting can be better.

We primarily use Zerto for disaster recovery.

Zerto ensures a smooth transition during a disaster when we need to automatically switch from our primary environment to our recovery one. Zerto offers us disaster recovery in the cloud, which is essential because we don't need to pay upfront costs for infrastructure when doing the DR process. Zerto helps to protect our VM-based applications. 

The solution has also reduced our RPO. The RPO during testing was less than 15 minutes. Zerto reduces the amount of work we need to do because some of the steps are automated. It takes about five to 15 minutes to test. Zerto has decreased the number of staff needed for backup and DR. It only requires one or two. 

The core backup and disaster recovery features are the most valuable. The near-synchronous replication ensures we will be able to keep the business running if something happens. 

There's a mandatory VMware version, so we need to update our VMs in order to access our data. Zerto should work with all VMware versions. 

I rate Zerto nine out of 10 for stability. 

I rate Zerto eight out of 10 for scalability.

I rate Zerto support eight out of 10.

Positive

We are using Zerto and Acronis. 

Our IT team handled the deployment, but I don't think it was complicated. 

Zerto is a little expensive.

I rate Zerto eight out of 10. 

We use it for disaster recovery. We do disaster recovery in the cloud as well. We also do routine testing of the disaster recovery functionalities.

We do disaster recovery in the cloud. Having DR in the cloud is absolutely fundamental. Backups are great, and disaster recovery is quick. If something is down, with the click of a button, we would be able to spin up multiple assets. Zerto allows us to do that.

We primarily have Azure, but we also have some integration with AWS. We found it pretty seamless. There are a couple of pain points every now and then with setting up policies and getting things to work as expected, but their support is very helpful for any of the cases that we run into. Whether it is running against RTO or having issues with certain VMs and certain workloads, we have been able to work through these issues and get it functioning as expected.

Zerto has been very helpful for RPOs. It definitely keeps us at our target recovery point. It is definitely the most important toolset for us to meet the RPOs.

Zerto definitely helps our engineers sleep better at night because we know that we can meet our RPO. We have an immediate button if we have to do a restore. Sometimes, we look in Zerto first rather than having to dig out of backup. That is probably Zerto's highest value-add.

It does near-synchronous replication. CDP has definitely come a long way. They were the first ones to do it, and they have definitely done it the best in my opinion. Other solutions that are out there are trying to emulate it, but in our stack, Zerto will always be the one on which we rely the most for continuous replication. For production workloads, this continuous replication is absolutely critical. We have a lot of SQL data and things that are constantly changing. It is sometimes a little bit of a struggle for Zerto to keep up with that much change rate, but with the tweaks that we have made, it has definitely been more possible. It is definitely something that is important to us, and for production apps, it is absolutely key. 

There are a lot of features. The UI is straightforward. It makes it very simple to group our resources and understand that our production workloads are covered because we can set them up as granular or as non-granular as we want. If we want to select an entire cluster, we can do that, or we can group it by application, which is the best practice and what we do as an organization.

The biggest pain points we have experienced are related to some of the SQL-intensive workloads just because the VPGs struggle a little bit to keep up. That might be because we are pushing too many transactions. That might be on us, but that would be my main suggestion. There might be a way to tweak the settings. There is an option to exclude scratch disks or temp disks in SQL, and that helps, but we still struggle a little bit with the databases with high transaction volume for the VPGs to keep up. We have done a little bit of work with the monitoring features that they have in the portal to identify whether ZVM or something else is overloaded and then allocate more resources to it, but there can be a little bit more transparency. If there is something they can do along those lines, that would be awesome.

Deployment is an area that can be improved a little bit. Sometimes deploying new ZVMs and things can be a little confusing. Also, with the supportability matrix, there is a little bit of a gray area sometimes as to which version is supported. There is some opportunity there to improve transparency around versioning and what to use moving forward for all workloads.

I have been using Zerto for about five years between multiple organizations.

It is very stable. We have no issues. We do not have to worry that Zerto will go down. We shifted most of our on-prem into Azure, and it works flawlessly.

It is definitely scalable. It just works. We can add more VMs. We can add more ZVMs to scale with the business needs.

We are using it mostly for the production workloads. We have a couple thousand VMs.

I would rate them a nine out of ten. It is hard to get a ten out of ten. There is always more that you can do with support, but they are always very responsive. They helped us through multiple issues with different VPG replications. We have had some issues there, and they were always very good at guidance. They always have a solution and a lot of good documentation as well to reference before opening a case. That is helpful. 

Positive

I have only used Zerto in the past. That is the one I am the most familiar with and comfortable with. I can compare it to other backup tool sets that I have used in the past, but I know Zerto is not exactly a backup solution. 

Its UI is very simple. I always find what I am looking for relatively easily. As they have evolved the web portal, it has only gotten better. The UI is definitely on point today.

I believe we have seen an ROI, but I do not know the exact number. We are definitely seeing a good return from what we have put into the Zerto product. Our business users said that it is very important to them to have disaster recovery and for us to be able to perform quarterly tests with all these different application stacks. We can show them what it is like to bring up a bubble environment and do full testing.

It was a little before I joined the company, so I cannot comment on the solutions they evaluated. 

I would rate Zerto a nine out of ten. There is always room for improvement. There could be a little bit more transparency around releases and what version to use. They have done some rebranding in the past such as ZRA and ZVM. There is some confusion there sometimes related to some of the internal terminology when you do not work on it every day, but overall, we are very happy with the product. It does what it is intended to do, and as a customer, that is all you can ask for.

Our primary use cases include replication and disaster recovery. 

We use Zerto to help protect VMs in our environment. We are really happy with RPOs (Recovery Point Objectives).

Both the Recovery Point Objective (RPO) and Recovery Time Objective (RTO) are fine. They always meet our requirements. Their significance is not driven by a single factor but rather by the customers. Some customers require an RPO of a few hours, while others require up to 24 hours. It depends on the specific needs of the customer.

The most valuable feature for us and for my company is that we are replicating most of our production customers to the DR site, and we can do testing whenever we want. The customers are very happy with the way we do the testing while the primary is still running. There's no disturbance to the primary production site. 

The most important function right now is that we have another DR site, which is in a very old environment that is non-Zerto. We were log shipping there through another method. We are migrating over to the Zerto platform so we can replicate it to the new DR site so we can shut it down. That's going to be a lot of savings for us, shutting down the old replication with the other way. That will be one of the benefits too.

Zerto offers near-synchronous replication, which is always on and constantly replicates only the changed data to the recovery sites within seconds. It doesn't really bother us because we have enough bandwidth. Since we do a 24-hour recovery, it does not take a lot of disk space. It's an issue sometimes because I have to constantly increase the space on the disks at the DR site. On the VPG (Virtual Protection Groups), I have to constantly increase the space. That's where the alerts are being generated too.  

Someone suggested to me that I should turn off this feature, but that's not the way to do it. Turning it off temporarily is similar to applying a bandage.

Moreover, we have plans for DR recovery in the cloud. That's our next step, and it's likely to be on the agenda. We probably will use the license we have for that, which we can use as of today.

Zerto generates many false positive alerts, which is annoying. I still have thousands of alerts in my inbox, and those are false alerts. When I check there's actually no problem.

I have been using Zerto for four-plus years. 

It's very stable as far as we're running. Even though I'm running it on a very old Windows Server 2012 server, it's still running fine without any issues. 

Scalability-wise, it's pretty good, too, but we're not there yet. We are using it for small 50+ VMs we are protecting right now, but we are continuously growing. We may have to expand with multiple ZVMs (Virtual Managers). We're going to install multiple. We just have one on each side, which we don't have an issue with.

The customer service and support are really good. I wish they had phone support too right away, but we have to go through their website and open a ticket.

Moreover, there's always going to be something a person is not one hundred percent knowledgeable about. He has to escalate to the top tier. 

Positive

Somebody else did the deployment in the company and I took it over after that. I just recently upgraded to the latest version without any issues. Zerto is very easy to upgrade.

There is an area of improvement for Zerto folks. Every time we do an upgrade, if we are three or four releases behind, we have to go to the next level, then the next level, and then the latest. This is a pain. We would like the ability to skip to the newest version. 

ROI is pretty good compared to the recovery compared to the investment we have. The solution is worth it. If we go to the cloud, the ROI is definitely going to be much more.

The pricing is pretty decent. We got a good deal. 

I really like Zerto. I've been using it for many years. It's a quick recovery. I failed over the complete site to the DR many times and then failed back to the production without any issues. 

We have VMware SRM but we are not using it. We have a license, we can use it, but we're not using it because Zerto is our primary right now. 

Zerto is very easy to use. It's not dependent on the hardware. It can decouple from any hardware. You can use it, even if you have different hardware at the source and the destination. That was the biggest attraction when we got into Zerto. It's pretty decent. 

I would rate Zerto a ten out of ten.

We use it for disaster recovery. We were looking for faster recovery time objectives. Our primary use case is protecting virtual machines in our environment.

It's improved our testing frequency, and that has definitely helped.

And the effect on our RPOs has been very good because of the continuous replication; you get more checkpoints. Compared to other disaster recovery solutions that we've used, it's much more efficient when it comes to recovery. It's much more resilient and provides a better experience. It's a better product than the traditional backup and recovery methods we were using.

Zerto has also helped reduce downtime in some situations. We can recover systems in minutes, versus hours. There has been a significant improvement in our RTOs.

It has also definitely helped us to reduce our DR testing on the order of hours and days.

The ease of use is one of the most valuable features when it comes to making changes and configuring. It's very easy to set up and configure. It's a great product.

Another very important feature, because I work in a very high-transaction environment, is the near-synchronous replication, and it works well.

They just came out with improvements for ransomware protection last week. I haven't used them yet but, overall, security and preventing ransomware is really a hot topic these days. I would like to see it detect when the ransomware occurs and provide more information on it.

I have been using Zerto for approximately five years.

It's very stable.

It's scalable. I plan to increase our usage of the solution.

I have not contacted their tech support.

We were using typical backup recovery from tape or disk. Zerto is far easier to use, simpler, more efficient and reliable, and more effective than traditional disaster recovery tools.

It has not replaced all of our backup solutions. It's another tool to prevent a disaster.

Our deployment is on a private cloud. We have compute, storage, and network that we replicate to. The initial deployment of Zerto was straightforward. It took less than 30 days to get it fully operational.

We used it in our test environment first and, once we validated that everything was functional, we included our production environment.

The maintenance involves keeping the versions up to date and there are agents that have to be updated as well.

We had a managed service provider set it up and deploy it. On our side there were one or two people involved.

I can't quantify the ROI because we haven't used it in a disaster. It's more of a cost-avoidance solution, protecting the organization.

The pricing is very reasonable. There are no costs in addition to the standard fees.

We looked at Symantec, Veritas, CommVault, and Rubrik.

Have clear requirements on what your RTO/RPO requirements are, and which applications will be involved. You need to have clear business requirements and align Zerto with your business continuity plan.

Zerto is very innovative and they're constantly making improvements. It took some time to realize some of the benefits but it's been a great journey.

We use Zerto for disaster recovery and DR testing.

Zerto has improved our restoration time and made it easier to test software upgrades. It has simplified tasks like decommissioning a site and replicating virtual machines from one location to another. 

It gives us peace of mind that we can recover our systems in minutes or hours instead of days. Zerto is also helpful for insurance purposes. Our insurer wants to know how long we'll be down in a disaster. Of course, the company owners love Zerto because we won't lose business if something happens.

When we had a firmware failure, it saved us time performing a failover to our DR site. It isn't easy to calculate, but it saved us days and possibly weeks of downtime. 

A firmware update on our SAN went wrong, crashing the entire device. We're in Rhode Island, and it failed over to our DR site in Tennessee within 18 hours. Our users didn't notice because it happened on a Sunday. They had all their data when they returned to the office, and we reverted the following weekend. Without Zerto, some applications would've been down for days, if not weeks. 

Zerto has also improved our DR testing. In the past, we had to test over the weekend, but we can now do it during the work week without any outages. Our IT staff doesn't need to come in over the weekends, so it doesn't affect their personal lives. Zerto has reduced our DR testing time by about 50 hours. 

The interface is easy to use. It's not intuitive per se, but the average IT expert will have no problems using it. A non-IT person might have a little difficulty at the beginning.

I love Zerto's near synchronous replication because I can get up-to-the-minute data back in a disaster. This capability is essential because a disaster could cost the company money and even cause it to go out of business. We can sleep better at night knowing we can restore our systems in minutes.

Surgical blocking of unknown threats is a feature that's available on the cloud, but we're on-premises. However, it's certainly a feature I'd like to have, especially with all the malware and vulnerabilities. It's great to know that Zerto offers this capability, but we don't take advantage of it because we're an on-prem customer.

Zerto is too reliant on VMware's vCenter. It's tough to upgrade, move, or do anything related to virtual servers with vCenter.

Zerto is highly stable. We haven't experienced any noticeable bugs. We're sometimes too stable. Sometimes I want to upgrade my VMware ESX host, and I can't because they have not approved it on their matrix. They usually take about a month or two to accept it as a supported system, which is probably the industry norm or better, but I want it faster. 

I rate Zerto support 10 out of 10. Zerto's support team is knowledgeable and goes out of its way to help. Instead of just throwing KB articles at you, Zerto support walks you through the solution.

Positive

We previously restored everything from scratch using tape backups, but we had no software disaster recovery solution. It hasn't replaced our legacy backup solutions because we do not use Zerto as a backup. Our hardware backups are still online and working. 

We do not use Zerto as a backup solution. It is mainly for recovery. However, we use Zerto/Keepit for Office 365 backups. We still back up to tape and restore using Zerto. It has made the recovery around 20 times faster. 

Deploying Zerto was straightforward, and I did the job by myself.

We've seen a solid return with Zerto

Zerto costs more than most, but we negotiated a fair price. 

We have Veeam Backup and Replication, but we don't use it for disaster recovery. We also tried another solution for Office 365 backup. We prefer Zerto replication for the speed and support. 

I rate Zerto 10 out of 10. When implementing Zerto, you should consider your internet speed and the difference between the WAN connections at the sites you want to replicate. You need enough bandwidth to handle the volume. 

We mostly use it for disaster recovery purposes. We do a lot of migrations as well, e.g., VM from one site to another. We use Zerto for that, as we have hundreds of VMs that we protect as our main DR position using Zerto.

In general, our DR position is entirely based around Zerto. We use it for everything. We just have a couple things that we don't put on it. There are a couple of Oracle things that we replicate with different methods, but we pretty much do everything related to DR with Zerto.

We are not using it for backup. We are using it for continuous DR and replication between two on-prem sites. 

We have two data center sites with bidirectional replications. Each site protects the other site and we have our VPGs that go back and forth.

We perform more DR testing now because it is so easy. For example, what we are doing right now is baselines on our recovery time objectives, determining, "Okay, if we recover one VM, it takes this long. If we recover another VM this size, it is this long." Then, we recover 10, 100, and 800. That way, we get kind of a forecast, when we add VMs, about how that will affect our DR stance.

When we need to move a VM from one data center to another, it is replicated there. We don't need to do any snapshots of storage. We just make a VPG for it, do a move action, and it is just there. It works really well.

The test features have been really good for us. Our DR testing goes very quickly and easily now for all our stuff with Zerto. We have our priority recovery process, where we cover our databases for our app servers and web servers. All our teams pretty much get their VMs very quickly. The RPOs are very low. 

It is very easy to use. There are a lot of training materials online on the Zerto portal, which make it very simple to learn and use. You could go from not knowing how to use it to fully understanding all of it in a day. This can be done by using the Zerto University, getting your little certification and making your boss happy. It is pretty easy to set up VPG-wise.

You have a 24-hour journal. The amount of disasters and things that you can recover from using a 24-hour journal is huge, e.g., ransomware. We haven't had to do that yet, but the possibility is there. It is good to know that you can go back as far as you need.

I would like to see the app be more like the analytics site. Right now, when you go into the analytics, you need to zoom in real tight on your browser. You get a lot more from the analytics site than you do from the app. If they made those two more similar, it would be really useful for day-to-day monitoring of your stuff.

I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet.

I have been using it for at least three years in my job function.

We have had no problems with it. Stability-wise, I can only say positive things because we haven't had any real negatives with it.

It is very scalable. If you add a data center, then you just add a ZVM at that data center, link it up, and add your vRAs. After that, you are ready to start making VPGs. It is very simple to set up.

We don't have issues with scaling. If a vRA is getting a bit overloaded, it makes little vRAs. So, it kind of handles itself. We have our vRAs at the maximum size, as far as CPU and memory, that they can be. Our RPOs are really short, so we are doing pretty well for our size.

Zerto's support is always responsive. I have never had any problems with it. Our lead Zerto engineer does a lot more stuff than I do as far as with support. Typically, I will escalate to her. If there is an issue, then I defer to her. However, as far as my experience with support, I have experienced nothing but good things. The learning portal, myZerto portal, and analytics are very good. I don't have to use support very often, which is a good thing.

If I were to rate it, I would probably rate it as 10 out of 10. Every time that I have needed them, they have been responsive and quick. I haven't used them that much, but when I have, they have been very responsive.

Positive

We have used SRM, who is Zerto's main competitor. 

SRM was pretty quick. However, the speed of recovery with Zerto is so simple. It can failover, e.g., do whatever kind of failover you want it to do. You choose your VPGs, then you are off. It is really fast and simple. A lot of people could handle using it pretty easily.

I haven't found it to be hard. When you add a new host, you just go to set up and add a new host, then it builds a vRA. It is pretty easy to manage alerts. It will tell you exactly what is wrong, e.g., this doesn't have enough scratch disk, so you need to go update that. Or, this host is offline, e.g., you forgot to evacuate it, so then you need to take it out of Zerto. So, it will alert you to that stuff.

I have done my share of deploying vRAs. Though, our lead Zerto engineer handled most of that stuff from the initial setup.

We have definitely seen a return on investment. We can move any of our VMs from either of our data centers back and forth very easily, bringing them back and doing tests as frequently as we want. We will be doing two tests next week. At previous companies, we did one test a year. Now, we are doing different stacks, e.g., if we do 20, 100, or 700 VMS, then it will be this long. So, we can forecast additional workload and how much that will affect our DR position.

Zerto is definitely a lot easier to manage. My whole team knows how to use it, since it is very simple to use and intuitive. There are a couple people who use it and I am the secondary person. We have someone who basically lives in Zerto. She adds stuff on a daily basis and we are always on top of our updates. We are always looking at whatever new features come out. We try to maximize our journals. We are up to 24 hours on a lot of them. Our average RPO is eight seconds, and that is pretty good since we have 1,500 VMs and 280-plus VPGs. We have a pretty big on-prem environment. So, the good thing about it is the frequency and ease of testing because Zerto is very simple to use. DR has enough problems to deal with and Zerto makes things a lot easier.

We have looked at Veeam and SRM. We examined the marketplace, Gartner, etc. This product that management chose, and we are pretty happy with it.

Give it a try. Move some VMs back and forth to see how easy it is to use. The one-to-many is pretty good. We have two sites, so it is not a very big deal for us to do that, but it is very useful. 

I would rate Zerto as 10 out of 10. I love Zerto's CDP solution. It is really easy to use. It does everything that we need it to do and scales easily.

We're currently doing a two-tiered on-site and off-site replication, with one long-term retention being displaced into a cloud and one long-term retention being displaced to a third data center. We were looking to make our recovery solution more streamlined and efficient, that's why we implemented this product.

We're not as huge as everybody else. We just have large devices. We have four SQL servers running, each of which is about six terabytes, so our continuous replication is a lot larger than others. We also have multiple secured file storages in the two-terabyte range, so we replicate around 140 terabytes continuously, utilizing about 60 VM servers. Our primary and secondary production is VMware, and our third-tier backup area is a hypervisor. 

The most significant improvement is the reduced stress of running our operation. Before deploying the solution, we had two people on-call 24/7, one on-shift and one off-shift. Now our workload has been reduced, and we only have to give support over the phone, which rarely happens.

For this deployment, I realized the benefits very quickly. I already knew how the solution would provide a reliable safety net and offer a better risk-reward profile for our cybersecurity insurance. I knew this three deployments ago. The main selling points I presented for this deployment are the continuous replication, plus the reduction in man-hours and cybersecurity risk.

The whole package is valuable. The most useful feature for the company is the rapid RTO, which offers a faster return to operations and brings us back online quicker. The last time we had an issue, we recovered within about 36 minutes, which was probably the most valuable thing for us because, previously, it took four to seven days.

I've worked with Zerto since the beginning; I think it was when we were still on version one. Having that continuous replication, as we call it, where we have just a small delta point is paramount to being able to create that multiple mine backup solution or recovery solution. It's absolutely the product's selling point. 

Zerto is the simplest disaster recovery and data recovery solution I've ever deployed, and I've been doing this for 30-plus years. 

We have used Zerto to protect VMs in our environment. That's the entire solution for us; it's all virtual. They can even calculate a number now, and I have 30-day testing documentation that gives them real-time data that shows a 15 to 40-minute recovery. It's astronomical because they now have a number they can guarantee to the stakeholders. 

There isn't much comparison with other disaster recovery solutions, though it depends on the configuration. A more dramatic or complex multi-tiered recovery would expand the time, but we went from four to seven days down to under an hour. For that reason, it's almost incomparable to other solutions. Depending on the deployment, even the VMware Site Recovery Manager takes four, eight, or even 12 hours. We can bring things back online in under an hour. I don't know any other solutions that can do cross-breed virtual environments or multi-hypervisors with VMware, with different types of cloud. We can go with Microsoft Cloud, VM Cloud, or Google Cloud. It's not even a comparison. If you have a good product seller and a buy-in from your network engineer and your software engineer, it's an easy sell. 

We currently have over 600 days of saved downtime. It's almost two years now without a single moment of downtime, because we utilized the failover to do maintenance cycles.  

Our last collapse was when we were hit by ransomware just about two years ago. It took out 80% of our systems, and we were back online in 36 minutes. 

I use the orchestrator for DR testing. I run a simulated test every 30 days, and we do two live tests a year. Before my arrival, they had never done a test, but that's what we do as a standard now. It only takes two members of staff, me and one other, for the entire test. It's very low-volume in terms of staff requirements.

The solution dramatically reduced the number of staff involved in recoveries. Before my deployment of Zerto in this organization, they had one disaster recovery and had to hire 19 people to do it. When we had the ransomware attack, two of us recovered the entire solution within an hour without having to hire anyone. The previous recovery costs were around $20,000 for the staffing alone, not counting the loss of revenue. I implemented the recovery during my regular work shift.

There are quite a few elements in the long-term retention areas that I wish were better. The bio-level recovery indexing of backups is the area I struggle with the most. That's probably because I desire to do tasks that ordinary users wouldn't do with the solution. The standard medium to the large customer would probably never ask for anything like I ask for, so I think it's pretty good the way it is. I'm excited to see some of the new improvements coming in the 9.5 version. Some of the streamlines and how the product presents itself for some of the recovery features could be better.

We have been using the solution for two and a half years, and I've assisted in the deployment at three other companies. I personally have close to ten years of experience with it.

I've been using Zerto for close to 10 or 11 years, and the stability is probably in the 95% to 98% range. That's pretty good, and I give it an A.

This is the smallest solution I've ever deployed. It scales very well across multiple platforms and at a long-range. It's very scalable; I've implemented substantial deployments and deployments over huge areas. I'm impressed with the solution's scalability, especially the integration with vCloud environments.

I dealt with them recently, and they're pretty solid. The process is mainly automated, they connect remotely, and I don't have to explain much as they can look at the logs. With that capability, it does work very nicely.

I replaced the VMware Site Recovery Manager and a Symantec backup solution when I came in. I also replaced the third-tier snapshot replication, which they had never successfully tested or recovered from.

We switched because I begged them to. I've used Zerto extensively, and the amount of fluidity and flexibility it offers is necessary. It gives me peace of mind and allows me to sleep well at night knowing it will be alright, which is uncommon in this business. I said as much to the company and was able to convince them within about six months.

I used Veeam and some other bare-metal backup solutions before. Since virtual servers have been in place, Veeam and SRM are pretty much the two standards, with Symantec being the tape backup solution or virtual hard drive backup solution. Since Zerto came around and I saw what the product could do, it's all I ever push for when I get called in for a company that needs a DR plan.

I designed it all and already knew what I wanted to accomplish and what the product could do. Once we knew what direction we were going in and where the critical applications aligned, it was just a point of picking things up and putting them into placeholders already in the required image I designed for our purposes. It was pretty easy. It might take a little longer without prior experience and an idea of what I want to accomplish. It would still be pretty easy as Zerto provides excellent documentation. This is one of the most straightforward designs out there. End-to-end, with testing and approvals at each step, I think it took two and a half weeks.

I implemented the solution on my own.

I can't give an exact figure, but I would say that protection from Ransomware tech alone paid for the initial startup process and most of the maintenance needed. 

I wouldn't say I like the licensing pricing structure. Every year, it increases exponentially, which bothers me a little. It's worth it in terms of the value, but I worry the price will increase even more often after the Zerto merger. I still think it's worth it and that the solution is cheaper than the others. 

We evaluated Symantec, and NetApp, and we brought in Veeam.

The main differences between Zerto and the other solutions are the continuous replication capabilities and the ability to have two continuous replications simultaneously. These were major selling points for the company. With snap replication from NetApp or even Veeam, there isn't that consistency between multiple divisions. I showed the company we don't have to have VMware at the low MBR; we can have a hypervisor at a much-reduced cost, as the price was the last hope for the other solutions. 

I would rate this solution an eight out of ten. I don't give anybody a ten, as nobody is perfect. The best score I give is an eight, and they get that.

We don't necessarily use Zerto for immutable data copies as it's never been a requirement. I know it's there and what we can do with it if we need to.

We only use the physical solution because of the nature of our business, but we do long-term retention in the cloud. It is nice to have that long-term cloud retention, as it gives us another tier of data available for worst-case scenarios. 

I wanted to replace our legacy solutions, but we still have old-school solutions for legacy data recovery. We use Symantec for backup exec. on our bare metal, but I don't think it's critical because it's more for our legacy data recovery. After all, we're not like most companies. We have to keep our data for 24 years.
