HPE Zerto Software Reviews

Its primary use case is for disaster recovery of 10 servers that we have in-house.

The testing of failover and failback is critical to any company, especially if they're certified in some platform like we are with ISO 27001. It is a necessity, and one of the main reasons I purchased Zerto.

Live replication and up to the second type of failover are valuable. The fact that we can do test failovers and failbacks is important for our ISO certification.

More user support would be best for me because I'm not in the product all the time. So, having strong support is probably the most important decision on any products that we buy.

The price is another thing that they definitely need to work on unless it has changed. I purchased mine a while back. 

When it is up and running, it is just always running, but because we're changing our infrastructure, basically, everything has to be destroyed and rebuilt.

I know it is scalable with the backup solution. I don't understand why that wasn't there early on, but it is neat that they've added that functionality in there.

It has been a long time since I've worked with them. So, I would rate them a 7 out of 10.

It is rare that I have to contact them. We are in the process of redoing our VMware infrastructure. We have to reinstall the whole product, which we haven't done for a long time. So, I'm not that familiar, and we're probably going to have to pay for services where I would like that to be handled by support to help us.

It has been quite a while, but we used to use Double-Take to replicate some servers between offices. Zerto is much better at doing that functionality, and that's why we switched. 

The ease of use is definitely better with Zerto. The data recovery with Zerto is very fast. You just push buttons for recovery and flip back.

The initial setup was straightforward, but I had a team, probably from Zerto and not the consultant, that helped us with the installation. So, I had somebody right there holding my hand, and it was very easy to do.

That's hard to say because we haven't had a catastrophe. If we have a failure, hands down, I can't complain about that, but we haven't had any incidents.

Even though there is a fast speed of recovery and ease of use, I haven't measured the time savings and resource savings with Zerto. That's analytics, and we're not that detailed. We're user support focused.

It is very expensive. It is overpriced. No doubt. What held us up for many years from committing to buying it was always the cost. That's also why we only have 10 licenses.

We probably looked at other solutions, but I don't recall what they were at this time.

I know that they have a backup now, which they didn't have when I purchased originally, but we don't use that today. It may be something we'll look into. 

The solution is great. I'd rate it a 10 out of 10.

We have customers who come in for DR as a service, but we also do inter-cloud DR.

It has brought customers into our cloud, since this was a barrier to get in. We have used the migration model a lot to bring customers in. We just brought in a customer from Microsoft Hyper-V into our VMware file. That would have been a difficult challenge if we did not have Zerto as a tool.

Zerto has helped to reduce downtime with several customers. For example, we had a customer who had many of their VMs encrypted. They had about 40 to 60 terabytes worth of data. To recover that from backup would have taken days. We were able to bring them up at the DR site, getting them up and running, within hours. This would have cost the customer millions if they had been down. As a title company, if they would have been down, that would have disrupted a whole title industry, where people are trying to buy houses. If you can't get the title for the house, then you can't move forward. Other people wouldn't have been able to sell their house. There would have been a ripple effect. So, that was huge.

It has definitely helped our customers reduce their DR testing. We can do failover tests live in the middle of the day and generate a report, and they are comfortable with it. 

Journaling is by far the most valuable feature. We have used it several times for customers who have gotten ransomware and had to do a rollback. Having the right time period was important. Some of them had their backups encrypted. So, they didn't encrypt the Zerto machine seven days previously, and we were able to bring that back up.

I have been using Zerto for about seven years.

It is very stable.

It is very scalable. All the workloads go on hosts. So, in order to grow, you will need to have more hosts anyway.

From the relationship standpoint, we have never had a local rep in South Bend, Indiana. It has always been somebody in Boston, and there is not a lot of communication. That is one of the big things. We would like help driving the business and talking to our sales people as well as more involvement from them. We could really utilize it more, drawing more customers in, but we need help with that.

I would rate the technical support as seven out of 10. Where it becomes difficult is if Tier 1 can't help you, then it takes a long time to get to Tier 2 or the development side, if something is beyond their capabilities.

Neutral

We use VMware High Availability, which is one of the options in our cloud. It is a less expensive option. So, we have customers who want that. Also, we have tried Veeam Backup & Replication, which is not cloud-native, so we don't use that. However, a company, whom we acquired, was using it. So, we tried it out.

Zerto is a lot easier to use. It has a lot more features, as far as orchestration, than VMware High Availability. The reallocation of IPs and the networking part of it are not that great in VMware High Availability. Plus, the retention that you get with Zerto is better than High Availability. Veeam didn't get into that much, and there is no orchestration into the cloud. 

The initial setup is very straightforward. The wizard that you run through is just very straightforward. If it is a DR-as-a-service customer on my end, then I am just deploying it as sort of a cloud connect, which is very easy.

I deploy it for all our customers.

We have absolutely seen ROI. Over time, we make money off of the CPU, RAM, and storage of Zerto usage. We benefit that way.

In a world where others are catching up, e.g., VMware High Availability, there needs to be a less expensive option as well. When a customer has approximately 100 VMs, if you multiply by 40, we aren't charging a very high margin on it at all since the license is so expensive. We feel their pain. That is the most expensive part of it. The storage, CPU, and RAM are a lot less. It is the licensing that is really expensive. Whereas, with an option like VMware High Availability, it is a couple dollars per month. That is our spend that we are charged by VMware, then our margin is higher on those VMs. Giving us some ability to have higher margins, as an MSP, would be a good thing.

I would rate Zerto as nine out of 10.

Our use cases are disaster recovery and long-term retention against ransomware.

Zerto was part of our technology transformation initiative about five years ago, not only to protect our customers' intellectual property that we create for them, but also to protect our organization as a whole.

In a way, it has reduced the number of staff involved in a data recovery situation since we are contracted with insurance companies to help us recover. This solution allows us to be more self-sufficient, using our existing staff to recover.

Zerto has helped reduce our organization's DR testing to seconds to minutes. We have been able to save probably close to 200 hours a year.

If something happens, and we are out and about, I would like to be able to interface with it on our mobile phones. That would be great.

I have been using it for about five years.

Their technical support is really good. They do quarterly tests to make sure everything is working and spot on. Our Zerto engineer is local, so we work with him quite often just to make sure everything is working.

I would rate the technical support as 11 out of 10.

Positive

It replaced Veeam. Zerto is a lot easier.

Prior to Zerto, when we were looking at our traditional disaster recovery, we were looking at 30 days plus.

We have been able to reduce our RPO and RTO to a matter of seconds to minutes versus what our technology committee established as our metrics, which was 30 minutes versus a few days.

Knock on wood, we have never had downtime. However, it has given us better peace of mind.

I would rate Zerto as 11 out of 10.

We use Zerto primarily for disaster recovery replication between two sites.

We started to use this solution to help with disaster recovery planning and fast recoverability.

The solution is deployed on-premises. We have two different SANS by EMC, VMware as our DOS network operating system, and we have a mixture of Windows, Linux, Red Hat, and Cisco switches.

We haven't done DR in the cloud because we don't do anything in the cloud.

We haven't used Zerto for immutable data copies because everything is on-premises. We just use it in a VM environment for the VMDK replication.

It's made us feel more secure, and we used it a couple of times for failover, so it's an essential part of the business operations.

Zerto's overall effect on our RPOs has been business critical. It's almost as important as a running production server.

It reduced our downtime. We can recover in five to six minutes versus 12 hours. That amount of downtime would have cost our organization $30,000.

The solution saved us time in a data recovery situation due to ransomware. We got infected, noticed the infection within seven minutes, and restored it to a point in time. We failed over to our disaster site, deleted the infected server, and 24 hours later we replicated back to our corporate site.

It helped to reduce our organization's DR testing. It's easier to plan, and the procedure is the same no matter the operating system or the applications installed.

It reduced the amount of staff involved in data recovery. It also reduced the number of staff involved in overall backup in DR management, but we have not reduced our workforce because of it.

Real-time or near real-time replication is the most valuable feature. Our RTO is generally between six and eight seconds. The impact on our RTO is essential.

The ease of use is great. You just have to be familiar with it, know how to set up your virtually protected groups, and know what fits your environment the best.

I love the solution's near synchronous replication. It's business critical to our organization.

We use Zerto to help protect VMs in our environment.

It would be nice to have the option to do automatic failover, but right now the only option is manual.

Zerto hasn't replaced all of our legacy backup solutions.

I have been using this solution for about nine years.

I would rate the stability 10 out of 10.

I haven't had any issues with scalability. We don't have any plans to increase usage and buy more licenses, but we will if we need to.

Technical support is really good. We've used the solution for more than eight years, and we've only needed to call them three or four times.

I would rate technical support 10 out of 10.

We previously used VMware DRS. We made the switch to Zerto because of reporting and ease of use.

There was a learning curve, but the setup was pretty easy. For our deployment model, we have one VPG per server, so it's one-to-one.

For maintenance, there are quarterly patches, and we set up testing of our VPGs every six months.

Deployment was done in-house.

We've seen ROI in active disaster recovery and failover.

I wish it were cheaper, but I would purchase it again at the same price.

We haven't reviewed any other product in the last eight years, but if I can say that I can get six to eight seconds RPO and RTL, that's incredible.

Compared to other solutions, Zerto is just easier to use, it's not as cumbersome, it's straightforward, and training is easy.

I would rate this solution 10 out of 10.

For those who are interested in this solution, my advice is to evaluate it, test it, and buy it.

We're solving the issues of disaster recovery with it. So, our main use case is disaster recovery. We use it to do real-time replication of our data so that if we needed to failover for whatever reason or we had a disaster at our primary data center, we would be able to spin up in our colo disaster recovery location with minimum downtime. Our delay is about five seconds. So, if something negative were to happen to our data center, our DR copy would be within five seconds of the original copy, which is pretty good. We are also using it for testing.

Our setup is on-prem. It enables you to do DR in the cloud rather than in a physical data center, but we didn't go that route. We went the route of creating our own colo location. So, instead of leveraging Azure or AWS, we decided to maintain our own facility. Our primary data center is on-prem, and our disaster recovery location is a colo location that we control.

The current version that we're using is 9.5, which is the latest. When we installed it, it was probably version 8.

The mere fact that we're able to do live testing has definitely helped us with deployment times. It has helped us with troubleshooting as well.

It saves effort, time, and money. It saves us the effort of having to make sure that information is replicated. It saves us the time that would be required to build that ad hoc, and it allows it to be more of a point-and-click operation than something for which we have to dedicate more time and effort. Especially in our use case, we're not replicating a crazy amount. We're only replicating about 40 virtual machines and about 13 terabytes of data. It's not a small amount, but it's not a crazy large amount either. To be able to load all those 40 machines at one time with one click and then bring them up either in production failover or production test is fantastic. We haven't really been able to find any competitor that can do that at least as easily as Zerto. That was the driving force.

It has helped to reduce our organization's disaster recovery testing. We can now do it in minutes, whereas previously, we could never do a valid test. We could only test that our backups were copied. We could never spin them up and run them all. Barracuda would do point-in-time backups, but we didn't have any place where we could actually deploy and test them all. That's not necessarily a hundred percent on Barracuda, but from basically not being able to do it, we are now able to do it within a few minutes. 

It has saved all the time that would've been spent validating copies of virtual machines. It can now be used to actually test that everything is connected, everything is spun up properly, and everything is connecting and speaking properly. So, there has been a tremendous amount of time savings. People who were responsible for doing it have saved time because they don't have to spend an entire day testing to make sure that the backup is copied properly so that they can be recovered. Now, we can do a test failover in a few minutes and be able to validate it like that.

It helps to protect VMs in our environment. It has been great in terms of RPOs. Prior to using Zerto, depending upon the level of disaster, it took us hours, days, or weeks to recover. Now, the average recovery is nine seconds. That's pretty big. We went from hours, days, or weeks to seconds and minutes to recover.

Its overall impact on our RTOs has been fantastic.

Its main feature is continuous replication. We are able to have continuous replication, and we are able to have the information available as per recovery point objectives (RPOs) and how much data to retain. The real selling point was to be able to have those statistics and be able to test and show that the replication is occurring properly and then to be able to do live passive testing.

We can spin up our environment in DR without affecting production, which is probably the biggest feature for us. We have the ability to do passive testing. We can even test scenarios, such as installing software or changing software. We can make modifications without affecting our production environment. So, the test functionality of being able to test the failover solution and being able to bring up our virtual machines in a test mode is the biggest benefit.

In general, the solution is pretty good, but because it is geared toward simplicity, sometimes, when things go wrong, the answer is not very detailed so that things can be solved quickly. If things do go wrong, it does require a little bit deeper troubleshooting to resolve the issues. That's the only area where improvement could occur. There should be a little bit more details about if things go wrong, how to remedy them. 

Everything is meant to be simple. When something doesn't work, even though what you were trying to do appeared to be very simple, there are probably a lot of pieces behind the scenes. So, to be able to narrow down where in those 100 steps something went wrong can be a little tricky. When there is a failure, there should be a more detailed explanation of what the error is and how to remediate it. Currently, it's a little vague. A part of that could be because we use Zerto on top of Hyper-V. VMware still has a very large market share over Hyper-V and a lot of the information and a lot of the deployment plans are geared towards VMware. So, sometimes, there are new features that first roll out to VMware and then come to Hyper-V.

I have been using this solution for about three years.

It's a very stable platform, but sometimes, we've had instances where we've upgraded versions and went from version 8 to 8.5 or to version 9 to 9.5, and there were issues. When you deploy, depending upon how many host machines you have, something might go wrong with the deployment to a host. In that case, you have to do a decent amount of work so that you can remove your virtual machine and restart the underlying host, which is something that you try to avoid doing, but sometimes, that's required in order to resolve the issue so that you can do the upgrade properly and allow that. When there is a problem like that, it can affect the performance of the system, but that falls more under maintenance and upkeep. In general, it does run pretty smoothly. It comes down to the fact that whenever there is a problem, it's a problem. That's the same with anything. Everything works until it doesn't, but in general, it works more than it doesn't, which is what you want. I would rate it a nine out of ten in terms of stability.

Their tech support is pretty good. We've had issues where we have reached out to them, and in general, they're pretty responsive and helpful. A few times, we've had them jump on to do screen shares and pull information and do deeper dives into some of those errors that didn't have detailed inputs about the area we need to look into, and their tech support has been pretty good. Based on the help that they provided for the issues we had, I would rate them a 10 out of 10.

Positive

We were using point-in-time backups provided by Barracuda. The issue with that was that we were taking point-in-time backups, and we were saving them in the cloud, but if we didn't have a location to restore the data to, the backups weren't very useful. They were useful from the backup standpoint but not from a disaster standpoint. In such a case, our primary data center would be wiped out. We would have our cloud copy, which would probably be a day old, and then we would have to take that cloud copy and download it somewhere where we don't have machines. So, we would have to buy servers or buy something to download our backup copies to and then spin them up. That could potentially take weeks. Now, we already have the hardware in place, or if it was a cloud, we would leverage the cloud, but we already have the hardware in place. So, at any point, it's a matter of enabling, going live, and saying failover, and then basically, having our DR copy become live. So, the time to recover was the main reason for going for Zerto.

We still have the Barracuda solution in conjunction. A lot of that is due to the fact that we already have a long-term contract. We have a five-year contract with Barracuda. We probably don't need to renew that, but there are benefits of both. We have kept both solutions because they do slightly different things. The way we use Zerto is that it's focused mainly on disaster recovery. Barracuda gives us more of a long historical recovery for easily recovering things such as files. We have backups of virtual machines that might go back four or five years. You might argue that it is not worth it because a lot of the data that is multiple years old might not be of value.

The way it would work with Zerto is that we could keep a live copy within Zerto for 30 days. After that, we would have to take that data and throw it somewhere else for long-term storage, which would incur additional costs and adds a little bit. Because we already had Barracuda, we leveraged Barracuda for long-term retention. We don't use Barracuda for disaster recovery anymore, but we use it for point-in-time recovery. We take a backup that gets shipped to the cloud to have an extra copy that is just there, which then becomes part of a historical backup where we could go back six or seven months, whereas Zerto is only for recovering files up to a few days. Anything older than those few days would be recovered via Barracuda.

Zerto can do a backup for or recover data longer than that period of time, but it becomes a little bit different process. When we looked at Zerto three years ago, the ransomware, journaling, and being able to go back a few hours and restore your entire environment back to a point in time were nice features, but they weren't the selling point. The selling point was disaster recovery. So, that's the main thing for which we're using it. We are not looking at the ability to go back 30 days to recover a file. I definitely see it as a plus, but because it wasn't the initial selling point, and the way that we architected things, we don't necessarily use that right now. However, when our contract with Barracuda ends, instead of renewing, we could consider just buying long-term retention through a cloud provider and then maintaining a longer history with Zerto.

There is a lot that goes into setting it up. So, the planning has to be done. We were pretty much able to have it up in a few hours, but it also depends on your use case and the complexity of your deployment. Like anything, there are a thousand ways to skin a cat. So, it depends upon how you want to have it set up. It depends on:

• How complex groundwork do you want to put in?
• How isolated do you want your test case to be?
• How isolated do you want different things to be set up?

There could be a little bit more complexity, but in general, it's pretty simple to get going. Obviously, there is a lot that goes into it, but the actual work of setting it up, once you have those decisions made, is pretty straightforward. It's pretty easy.

We definitely did a lot of planning, but we did the actual deployment or the actual configuration of it before we engaged with the professional services aspect of our deployment plan. When we bought the software, we had a project management plan and support from Zerto directly. We pretty much did all the setup ahead of time by ourselves. So, in our case, the setup was very simple and very easy.

It does require some maintenance. There are always service updates that are available, and occasionally, there will be little bumps in the road that require maybe reinstalling or updating something. In terms of general maintenance, as compared to other solutions, its maintenance is probably a little bit less than other solutions. Maintenance is still required, but it doesn't require an extreme amount of maintenance to keep things running smoothly.

When we went to locate this software, we worked with ePlus. They made several recommendations on different solutions, and from those recommendations, we narrowed it down and picked Zerto.

I liked them a lot at the time. The sales rep that we had there was fantastic. Unfortunately, a few months after our project was purchased, our sales rep left the company, and then we just never really connected with any of the new people. That has not necessarily something to do with ePlus. They're a large, great company, but what really separated them and made that project beneficial was the account manager that we had during that time period. He was fantastic.

In general, it's pretty fair because it is software. In our case, we built our own colo. So, the cost of the colo was very expensive, and that's where a lot of the equipment is. The same thing is there if we were going to spin up in the cloud, but as a solution, in general, it's pretty fair for what you get out of it and how it works. It's not cheap, but at the same time, you get what you pay for, and it's definitely worth the cost. You just have to understand that the cost of the software alone is not the total cost of the project of doing ransomware protection or disaster recovery. It's a piece of the pie, not the entire pie.

We did look at other similar solutions, but what made Zerto the solution that we went with was the fact that it included the recovery of the actual virtual machine. Other solutions had the ability to do the same kind of synchronous or near-continuous data replication. However, if we had the underlying data replicated but our virtual machine's copy or our virtual machine configuration was different or was not at that target location, we would have to then configure those machines to load the underlying data. The feature that made Zerto useful was that it handled that and replicated the virtual machine information as well. So, we didn't have to do that. Once we configure and specify it to replicate a virtual machine, all the data that's associated with it and its configuration is replicated. We don't have to deal with additional steps.

Three years ago, when we were looking at disaster recovery options, a lot of the solutions were targeted at replicating the underlying data but not necessarily how to get that data usable. Getting the data usable part is often the trickiest and the most time-consuming part. So, when you don't have to take that into consideration because it's already being copied and it's current, your downtime associated with a failure event is reduced. That was definitely a selling point for us.

We looked at Veeam, and we looked at how we use Pure Storage for our underlying data storage. They have the capabilities of doing synchronous, real-time replication, which has improved a lot in the past three years. So, the limitations that made it less appealing a few years ago might have been removed now, but at the same point, that's only the underlying data. We would still have to recreate virtual machines that will spin up that data. There is no other real solution that I'm aware of that does this as nicely. Even some of the other Microsoft native solutions aren't as nice and user-friendly. They definitely don't give you the ability to do testing. We couldn't spin up a replicated copy without causing issues. Zerto allows us to spin up a test version of our production software or our production VMs without affecting the production copy.

There is a lot that goes into setting it up. So, the planning has to be done, but once it's running, it's very simple. If it's set up right, it literally involves a few clicks. Testing and failover can be done in a few clicks, which makes a very complex thing simple. So, if you set it up and you have the groundwork done, then with one or two clicks, you could do major testing, and you could do major failovers. From that standpoint, it's extremely simple to use once it's up and running.

They have a lot of other features that we don't really leverage 100%. We use it only for disaster recovery, but it also contains features for ransomware where you can recover files. Although we don't use that feature, that's definitely a benefit. We have recovered files from time to time but not because of ransomware. We maintain a history of up to 30 days for each of the virtual machines that we have. We have a different solution to recover files older than 30 days.

We don't really use Zerto for immutable data copies, which goes into the ransomware where you expect not to be corrupted by ransomware. We use it, but we've never had a case where we had to recover from a ransomware instance or anything like that. We use Zerto only for disaster recovery and continuous replication. We have a separate backup tool that takes point-in-time backups. In terms of the 3-2-1 rule for our organization’s recovery strategy, our separate point-in-time backups give us three locations. At a point, we have three copies of the data in different stages.

It hasn't reduced our downtime in any situations because we didn't need to do disaster recovery. So, from that standpoint, we don't have any baselines before or after.

It hasn't directly reduced the number of staff involved in data recovery situations, but the amount of time required per person or the time required by people for validation has greatly reduced. We never had anybody dedicated to it as their only function, but the amount of time that's required to do testing is significantly less. So, there has definitely been a saving of time. Similarly, there has been no change in the number of staff involved in overall backup and disaster recovery management. In theory, it wouldn't because, in most IT organizations, a lot of people wear different hats at different times. We didn't have a dedicated person or a dedicated team only to validate backup and recovery.

Compared to other solutions, I would rate it a 10 out of 10.

We use Zerto for our disaster recovery procedure and testing to ensure our servers and virtual machines can failover from a production environment if there's a catastrophe. We have a disaster recovery test twice a year and use Zerto to recover the environment.

We have two environments for Zerto. One is for the US, and the other is for Europe. We updated one last week to version 9.0, and the other still uses version 8.5 but I will update that today or tomorrow.

Zerto cut down the recovery time tremendously and improved our disaster recovery process. It made it easier for us to recover if needed during a disaster. Zerto definitely reduced downtime. The other software we used had a lot of manual steps. It was efficient, but our recovery time was longer. I estimate that Zerto cut our recovery time by at least 70 percent.

We had a disaster recovery four or five years ago. I can't remember what happened, but I believe something crashed in our data center, like a power outage. We did a failover of our network using Zerto from production to disaster recovery. We successfully completed the failover process in three or four hours without issue. The data was current, and the application owners could access their data and continue working while the issue was resolved. 

Zerto also brings down our costs. If we don't meet our SLAs, the clients are not happy and we get billed or fined. Every minute an application is down is costly for us. However, I don't think it has reduced our staff. We have a dedicated team for disaster recovery. While it doesn't cut down on the number of team members, It makes our jobs a lot easier.

Near-synchronous replication is an extremely powerful feature because it's like a mirror environment with almost real-time replication. Everything in my production environment is mirrored in the Zerto environment. I want the two to be as close as possible. 

If you have a disaster, we don't want your data to lag too far behind. You don't want to be an hour or two days behind. When you recover an environment in Zerto, the data is current.

I would like to see some graphical improvements in Zerto's interface. There's an option to export a list of all of our servers, but the information isn't presented the way we want. We want it in a specified sequence broken down by region, etc. We can't manipulate the data when we export it. Maybe they could change it to look more like an Excel sheet, and we can customize the graphics and data. We suggested these improvements to Zerto through their portal.

We've been using Zerto for six or seven years.

It's highly stable. We've had no issues. We haven't had an incident or any problems with Zerto being unavailable or maintenance that would cause an outage on our side. If anything is happening on Zerto's side, we're not affected and that is great.

We haven't seen any limitations so far. Zerto is constantly upgrading its products. There are upgrades every five months or so. They're constantly tweaking and making the product better.

I rate Zerto support nine out of ten. It's excellent overall. We've only had one issue in the past six or seven years. I think the person was maybe new to the team.

They prioritize calls based on severity. If the issue is affecting our environment and we can't get anything done, they'll escalate the ticket and help us immediately. If we just have general questions or a concern that isn't severe, they still respond quickly.

We previously used a site recovery manager from vCenter. It's effective, but it requires a lot of manual steps, especially when we deal with databases and so forth. Zerto is quicker, more efficient, and easier on the eyes. I'm a huge fan. 

We started using Zerto because vCenter required more steps to failover our environment. Zerto does all the steps that we would normally need to do manually, reducing our recovery time and procedure steps. Something that previously took 45 minutes takes Zerto 10 minutes.

The other solutions are still in place. We use vCenter and NetBackup for our legacy systems.

Zerto is user-friendly. When I set this up six or seven years ago, I knew nothing about Zerto. It was relatively straightforward to go from the vCenter SRM to the Zerto environment. It's intuitive, so I can log onto Zerto and figure it out without having to take a class or official training. I can log on and navigate through the screens. If I get stuck, Zerto support is always available.

There were two of us who set it up. I'm in the US, and the other guy is in the Philippines. He initiated it, and I finished it. We completed it in one day, but I don't remember how many hours it took. We did a quick check the following day to ensure everything was in line.

I contacted Zerto recently when I upgraded one of my environments to version 9. I had some general questions because a few of our VMs were not syncing. I was getting an error message because the recovery didn't progress, so I had to reach out to Zerto support. We actually figured that out on our own, but they pointed us in the right direction.

We tested one product for two or three months, but I can't think of the name of it. Zerto was easier for us to dive into and pick it up quickly. The leadership of the disaster recovery team made the final decision along with management. I don't know if cost played a factor, but Zerto was more efficient and easier to use. It was exactly what we needed.

I rate Zerto ten out of ten.

We've been using Zerto for data center migration, but we will begin using it for disaster recovery. Because of some data center issues, we're still using version 9.5. One of our data centers is at 6.5 and the other one is at 7, so we can't move any or upgrade to 10.

Zerto enables us to set the IPs and map everything out in our environment prior to migration. We can create VPGs and mass migrate applications, databases, and web clients. That was the selling point for us. The product is easy to use. We had a 30-minute onboarding process from our sales engineer, who showed us how to use it. 

We don't use near-synchronous replication yet. It will be essential when we start using Zerto for DR, but it isn't a big deal during our current migration. Once we have a DR site, it will be essential to have those time slots we can restore to in the event of malware and ransomware. 

Right now, if you have an error, it creates a link that takes you to a website to review information about the problem. It would be nice if Zerto could give you information within the app instead of referring you to a web application.

Zerto for two years.

Zerto is intuitive. We could set everything up in the environment within a day and a half and start migrating on the third day.

I rate Zerto 10 out of 10. 

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.

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.
