Saves millions and we can roll back by seconds or minutes
Pros and Cons
  • "Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."
  • "While going in, we were looking at the backup tool so that we had a DR tool and a backup tool, but they stopped developing their backup solution built into it. That was a bummer for us, so now, we have a DR solution, and we have a backup solution."

What is our primary use case?

We use Zerto for the disaster recovery capabilities that it provides us. It is for our Tier 1 applications. 

How has it helped my organization?

Zerto allows us to protect individual VMs. With the other solutions, we are protecting the storage that the VMs live on, which is costly, so Zerto does save us money.

Zerto has near-synchronous replication. It works very well. Our RPO or recovery point objective time was 20 minutes, and we were doing thousands of VMs. We not only met the RPO; we exceeded it. There were many times when it was just seconds behind.

We have used Zerto to help protect thousands of VMs in our environment. Zerto has had a good effect on our RPO. It has helped to exceed our RPO. Our RPO on some of our critical systems is 20 minutes, and we exceed that. Most of the time, we are under 2 to 3 minutes.

It is very easy to migrate data. We ended up migrating from one data center to another data center, and we moved 20,000 virtual machines with Zerto. It was great.

Zerto lowered our RTOs as well. As a part of the solution analysis that we did for the RPO and RTO, Zerto's interface to do a DR test or a DR recovery was the fastest. We had a 24-hour window to recover 5,000 virtual machines, and we were doing them in three to four hours.

Zerto has helped us to reduce downtime multiple times. We had one incident where we used it to do a recovery. The downtime was roughly about 20 minutes. We do not have a value on that because it is customers' health information. I do not know how it affected the end users or customers outside of our company, but it does affect them.

Zerto has saved us time. When files were deleted, we were able to recover the files quickly. While doing OS patching on the servers, when the servers failed on the reboot, we were able to recover all good things when it came to quick recovery on it. As opposed to pulling it from our backup, it has cut our time probably in three quarters.

Zerto has helped to reduce our organization's DR testing. A DR test or a recovery used to take us days, whereas now, it takes us hours. The system that we were using before took multiple engineers to do the DR test, whereas today, a single engineer can do the DR test, and then we need just a couple of engineers to do checks on it, so it saves us a lot.

Zerto has reduced the number of staff involved in a data recovery situation. Instead of a group of people, we now just need one.

We used Zerto for immutable data copies. It was good, and they were on a course, but they shifted their focus. They were doing DR specifically, and then Zerto started shifting over towards doing backups. We were very excited about their long-term backups, but when HPE bought them, HPE stopped that part of it because they were directly competing against their solution. At the time they were doing it, we were very excited about it.

What is most valuable?

The DR testing capabilities that it has are valuable. 

Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great.

What needs improvement?

While going in, we were looking at the backup tool so that we had a DR tool and a backup tool, but they stopped developing their backup solution built into it. That was a bummer for us, so now, we have a DR solution, and we have a backup solution.

For the actual application itself, we have put in our request for certain features, and so far, they seem to be adding those features. In their latest one going to version 10, they did an appliance, which we had asked about 6 years ago. It is great to see that they are doing an appliance. There would be even more savings for us now because we do not have to pay licensing for a Windows VM.

Learn what your peers think about Zerto. Get advice and tips from experienced pros sharing their opinions. Updated: January 2025.
838,533 professionals have used our research since 2012.

For how long have I used the solution?

I have been using Zerto for about 7 years. I have used Zerto a few times at different companies.

What do I think about the stability of the solution?

We have seen very few issues. It is one of the few solutions that actually runs. If you do your leg work and implement it right and go through all the design and other things, you do not have to babysit the solution. Care and feeding is what it amounts to. That is all you have to do, whereas with a lot of the other solutions, you have to babysit them.

What do I think about the scalability of the solution?

Its scalability is very good. It scales very easily.

How are customer service and support?

They could do better in regards to escalating an issue. I would rate them an 8 out of 10. In defense of support, I know it is hard because they are talking to somebody who has got 28 years of IT support. When I get on the call, I am probably dealing with someone who is just starting out. He has to go through his standard process. However, somebody like me is looking for faster support and would like to get to a real smart guy quicker.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

For disaster recovery, we were using VMware Site Recovery Manager, and it was not able to provide the recovery, the RTO, or the RPO that the company required. I went out and did a discovery for different DR solutions, and that is where I came across Zerto. Zerto replaced VMware Site Recovery Manager, and it saved us millions.

How was the initial setup?

Our deployment model is hybrid. I was involved in the initial deployment. It was straightforward. It was a lot easier than VMware Site Recovery Manager. It took us a week to deploy it.

In terms of maintenance, other than typical patching and upgrades, it does not require any maintenance. VMware Site Recovery Manager required a lot of ongoing maintenance.

What about the implementation team?

We implemented it in-house. There were just three of us involved in its implementation.

What's my experience with pricing, setup cost, and licensing?

The pricing is based on virtual machines. They need to do better in regards to their tiering pricing rather than one price per VM. A lot of times we have VMs that are lower tier, such as Tier 2 or Tier 3, but we pay the same price as for Tier 1. I know they are developing this out, but it would be nice if they could provide a little better pricing in regards to their tiering protection.

Which other solutions did I evaluate?

We tested four different solutions, and Zerto was the only one that was able to meet our requirements. We did PoC on Zerto and two other solutions. Zerto was by far the leader when it came to disaster recovery.

What other advice do I have?

To those evaluating this solution, I would recommend doing a PoC on it. Deploy it in your environment and test it. Most of the problems you are going to see are due to the replication, and that is the site-to-site connection. One of the problems that I have experienced with Zerto has been related to replication, not the solution itself.

We have not used Zerto for blocking unknown threats and attacks. Thankfully, we have not had that. We do not have experience of that, thankfully.

We have used Zerto to do DR to both AWS and Azure, but the ability to do disaster recovery (DR) in the cloud is not something critical for us because the health insurance requirements for certification do not allow us to put our Tier 1 data in the cloud. Also, because our applications are multi-tiered where they reach out to the mainframe, Solaris, and other equipment outside of the virtual environment, it did not make sense to go to the cloud with it, but we do have it. We have a development environment there. A lot of times, we will use it to refresh the development environment. So, it is important, but in our case, it is not critical for us. 

We have not had any issues utilizing Zerto to support DR on AWS, but AWS is on the slower side. The reason is that for the connection to AWS, even though it is a direct connection, the speed does vary for us.

I would rate Zerto a 10 out of 10.

User-friendly interface and automation help with recovery and DR tests
Pros and Cons
  • "I am quite familiar with the user interface. It is easy for me to operate and perform different operations because I am an experienced user. In my opinion, the user interface is easy to understand and operate. The user interface is user-friendly."
  • "Zerto helps with quick recovery and integration with other processes."
  • "One improvement could be addressing the market segment related to physical servers. I understand this is a limitation of Zerto's technology. Still, from a customer's perspective, I would ask the vendor to find a solution to use Zerto for virtualized physical systems, such as physical servers."
  • "As a user who used Zerto for eight years, there are specific issues that it cannot address. For instance, recovering physical servers is directly connected to the virtualized solution in use, meaning your infrastructure needs a VMware or Hyper-V solution."

What is our primary use case?

We implemented Zerto because we wanted a flexible and quick tool that allowed us to recover in different situations. This purpose was successfully fulfilled by Zerto during the proof of concept phase, so we implemented it.

How has it helped my organization?

Zerto helps with quick recovery and integration with other processes. Providing as a service approach allows end-users to operate and perform recovery operations on their own assets based on their requirements and schedule preferences. It helps not only with recovery but also with DR tests that need to be executed at specific time frames, such as out-of-business hours. We had a few different requirements during its implementation, and Zerto helped us very well with all these needs.

Zerto has some specific options for replication, but it is mainly for virtual machines. We mainly use it for virtual machines. Zerto is not suitable for physical servers, but it can be used for virtual solutions such as OpenShift, Kubernetes, etc. In terms of its effect on our RPO, as I have not used a similar solution previously, the RPO value that we are getting is very good. It fits the requirements that we have from our customers because what we provide to our customers needs to be proven by the tests that we perform. Usually, their expectations are much lower than what we receive from Zerto. For example, we have application owners for whom 24 hours duration is enough to recover the business as compared to the 10 minutes that I have using Zerto. We use Zerto in real DR exercises and ask our customers to verify the results and the status of the recovered system and answer if the recovery was successful. We provide them the time needed to recover their system, and often, it is much quicker than what they require, so from our perspective, Zerto is very good. However, we cannot verify everything because we have some limitations in our DR test scenario. I can be 100% sure of the results of recovery only in the case of a real disaster on my infrastructure. At this time, based on the DR tests, it meets my customer needs.

We conduct DR exercises at least twice a year to measure the downtime we would have in the case of a real disaster. We simulate the disaster in a controlled environment and perform all related exercises. Once all activities are performed, we measure the time needed to recover systems from the data center that is down due to a natural disaster or technical issue. We get an idea of the downtime but the actual downtime varies depending on the issue type. It might not always be predictable or reduced through tooling as network or server issues can arise. In some specific scenarios, the downtime could be lower by using Zerto, whereas in some cases, Zerto would not help much. Based on the results of disaster recovery exercises and the RTO measured not only for one application but for recovering all of the applications in affected data centers, we can say that the time we need to recover the full data center is much lower than using traditional backup recovery solutions. Recovery with Zerto is much faster because we can recover in parallel many systems.

What is most valuable?

I am quite familiar with the user interface. It is easy for me to operate and perform different operations because I am an experienced user. In my opinion, the user interface is easy to understand and operate. The user interface is user-friendly.

Another important feature is the tool's automation capabilities, as it provides an external API to integrate with other tools and processes. This allows for a comprehensive IT ecosystem within a single dashboard, tailored to specific needs. Some operations can be limited for end-users. All of this can be provided not only through the GUI but also using the API. You can create your own application, integrate it with Zerto API, and develop features in your own application. You can use the API to integrate with your application and provide only the features that you want to end-users, facilitating custom application development. You can split the responsibilities based on the roles provided as well as based on your requirements. It is very flexible. From my point of view, the end-user experience is very good as an administrator of the tool and as the person responsible for the disaster recovery process.

What needs improvement?

As a user who used Zerto for eight years, there are specific issues that it cannot address. For instance, recovering physical servers is directly connected to the virtualized solution in use, meaning your infrastructure needs a VMware or Hyper-V solution. It cannot be used for bare metal physical server solutions. One improvement could be addressing the market segment related to physical servers. I understand this is a limitation of Zerto's technology. Still, from a customer's perspective, I would ask the vendor to find a solution to use Zerto for virtualized physical systems, such as physical servers. 

A second area for improvement relates to the speed of implementation. There should be a more streamlined process for enterprise applications.

For how long have I used the solution?

I have used Zerto for about eight years.

What do I think about the stability of the solution?

I did not encounter any issues during the operations, so I would rate it a nine out of ten for stability, so there is room for improvement on the vendor's side.

What do I think about the scalability of the solution?

From my perspective, given the size of my infrastructure and the limitations based on the vendor's requirements and documentation, it fulfills my needs. Therefore, I would rate it a ten out of ten because I have not faced a situation where I needed more than what it provides.

It is being used at multiple locations.

How are customer service and support?

I have the opportunity to use Zerto support, and I have used it many times for various questions and solving different issues or problems I encountered in my infrastructure. I would give them a rating of ten because it represents the highest level of support based on the technical knowledge of the support team, response time, and effectiveness of the provided resolutions.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Zerto was the first tool I started using once I took on the disaster recovery manager role in my company. I did not have experience with other tools.

How was the initial setup?

The speed of implementation is an area for improvement. While deployment on straightforward infrastructure is easy, an enterprise company with strict access and vulnerability limitations requires manual configurations. This is neither easy nor quick. 

Implementation depends on the environment and customers. From an enterprise perspective, I expect a more streamlined implementation process, as many steps require manual action. This challenge is specific to my company due to limited access and port blockages. Implementing such tools is a one-time task. My intention is to provide feedback related to the installation process, not the operation.

What's my experience with pricing, setup cost, and licensing?

I do not have much experience with different tools, so I cannot directly compare Zerto with other solutions. While conducting our proof of concept, I compared prices with just one other vendor. At the time, the price for Zerto was more favorable. Since I only use this tool and I do not have the need for others, it is difficult to compare the price now.

What other advice do I have?

Zerto is an asynchronous replication solution. It provides what they call near-zero RPO value. There is a delay of a few seconds depending on the parameters of your infrastructure, such as the bandwidth, the workload in your infrastructure, the distance between data center latencies, and the speed of the network connections. There is no one solution that meets all the needs. You need to decide whether you need a synchronous or asynchronous solution. You should be aware of the pros and cons of both and the requirements of your organization. Synchronous replication might be risky in some specific situations. What looks good on paper might not always be good in reality. Zerto meets our needs for flexibility. It mitigates different problems related to infrastructure, even though there is always the possibility of losing some data.

I would rate Zerto a ten out of ten considering the features, support, feature development roadmap, and the frequency of new features provided to customers.

Which deployment model are you using for this solution?

With Zerto we can pick and choose what we want to fail over and at what time
Pros and Cons
  • "We have seen ROI. It reduced the time for failover and failback by 90%."
  • "You can create a VPG and put anywhere from one to 17 servers in that group. We build them one by one. If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up. When you change them now, it only applies to the copies from the points when you changed it. I wish it would purge that older data from the past. Right now, we have to build a new VPG, which is not a big deal as it is just a few screens."

What is our primary use case?

We are failing over approximately 250 systems. In many ways, this could impact 3,800 insurance agents across 11 states. 

There are two sites: the source site and the production site. Those are failing over to another data center about 150 miles north of my location.

How has it helped my organization?

When we went from the original DR plan that we had with Double-Take to SRM, we were able to fail over in an hour and a half. We did all the storage groups in bundles, and we are like, "Wow, this is unbelievable. This is awesome." Then, we went to Zerto, and it was like, "Oh wow, we can pick and choose how we want to do this." So, Zerto provided us with a lot of value. 

We went from testing in a week, e.g., we would say, "Alright, we are going to set aside Monday through Thursday to test all the apps which have been deemed 'need to be tested', and make sure for DR purposes that they are working correctly." We went from that to a day. We can do it whenever we want much easier than before. Instead of having to do it in a group, you could have it where there is scratch space and all the things that are needed, where all the changes and deltas are being cached. Now, we can do a small group of people anytime that we want, or whenever. 

We haven't done it all in a day. Our plan is to have it fail over where we can get it done quickly enough in that morning, e.g., if we have all the testing, testers, and developers lined up, then they can test and we can have it done all in one day.

It has reduced staff stress. We are not big on cutting staff because we run pretty thin. We have even seen growth in the amount of staff involved in backup and DR management. There will be two leads going forward, sharing the primary duties.

What is most valuable?

The most valuable feature is the failover testing and being able to do that in a granular fashion. We can pick and choose what we want to fail over and at what time, then how quickly it fails over. We fail them over into a bubble, which means our developers and other testers can go in and do whatever they want. They are not impacting production outside of the bubble.

The reporting function is a big thing that we like. Our upper management and execs are always like, "Hey, we need to report about what you did." So, we can print out a report that is 200 or 300 pages long, and go, "Here you go." It was a little overwhelming the first time they got it. They were like, "What?" I am like, "You asked for a report. This is the report."

For the last three years, I was a secondary admin. We got into a situation where they were like, "Hey, you're the lead. You need to immediately be the lead." I was like, "Okay, alright." So, I was able to go in and create the protection groups and replication servers. We run VMware so we were able to push that out to the hosts, uninstall and decommission stuff. I was able to get that squared away within a day or two. It is very easy to use. If I can do it, anybody can do it.

The Zerto’s near-synchronous replication is very important. We used to say, "Hey, if we don't have this and if the building blew up from a gas leak, then what would we do?" Now, it is not just disaster recovery, but there are departments of insurance requirements for federal requirements going, "Hey, do you have a disaster plan in place that will successfully run? Can you provide me with those reports?" It also checks that box since we have requirements that need to meet for customer data. They need to be able to retrieve that data, either at the running site or production site. Or, in the case of a disaster, we will need to provide them with that information. So, it checks multiple boxes.

What needs improvement?

You can create a VPG and put anywhere from one to 17 servers in that group. We build them one by one. If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up. When you change them now, it only applies to the copies from the points when you changed it. I wish it would purge that older data from the past. Right now, we have to build a new VPG, which is not a big deal as it is just a few screens. 

For how long have I used the solution?

We have been in the Zerto world for four years, and I am the lead on Zerto now.

What do I think about the stability of the solution?

Stability-wise, I would probably give it 10 out of 10. It is very stable. If there is something not running correctly, then it is an outside factor. It is either the admin or a connection to the other site. With the dashboard, it will show you that you have this many protection groups built. Everything is an individual green square, but when there is a problem, then you will see red. It is very simple. If it has a problem, you will see something. I have not dealt with a problem where Zerto is just not working. It is usually user error or sort of outage. It is reliable.

As far as Zerto replication and DR purposes, it has not caused us any outages.

I have answered stuff for Zerto before, and they are like, "Why do you like it?" We say, "Because it works." For so long, we had stuff that didn't work for so long, and this solution works.

What do I think about the scalability of the solution?

As long as you have the license to protect the VMs, then you can scale it as big as you want. 

We are currently protecting 325 VMs. We have plans to expand in the future.

How are customer service and support?

My dealings with the technical support have been top-notch. They are very good. I would rate them as 10 out of 10.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

We had Double-Take and were replicating to a site with SunGard, then we swapped. It was kind of a nightmare for us to get it working the way that we wanted. I am sure it is a great product, but the way that we needed it to work was just not working. Then, we went to VMware SRM, which worked great and went off without a hitch.

We then wanted something with a quicker recovery point objective (RPO), and that is when Zerto came in. They allowed us to failover in a granular fashion. We could pick and choose how we wanted to fail over in DR tests. That is a big part of our DR testing. Enterprises want to be able to know that they have a successful test and can run in a failed over environment, so the test is 50% of that. The other half is, “If we had to declare a disaster, where would we be?” The RPO is two to three seconds with Zerto. I have talked to people with Unitrends and several other companies who say that you can’t get an RPO that low, but that is what we have. Today, it is very fast today.

When we need to do our DR test on a specific day, Zerto has allowed us to be able to do that in granular fashion. With SRM, you had to fail a group of servers over. While that may have changed, at the time you could only do them by storage volumes. With Zerto, it didn't really matter. It has been like, “Which ones do you want to fail over? Do you want to do just your SQL servers?” This has allowed us to have a more granular approach to testing and DR testing. It ensures that we can do it in a certain way and confirms that our actual DR plan is a good plan.

We didn't have anything that worked for so long. I think Zerto kind of showed up and was in the great spot where they couldn't be any worse than what we had.

How was the initial setup?

I was not involved in the initial setup. This has been kind of thrown in my lap, and it has not been a nightmare at all.

What about the implementation team?

The prior admin hired services for updates. Going forward, I will probably do them myself.

What was our ROI?

We have seen ROI. It reduced the time for failover and failback by 90%. I am not saying that the products I mentioned earlier are bad products. They just didn't work well for what we wanted.

Zerto has had a significant impact on our RPO. It is a double-edged sword where our RTO and RPO have allowed us to almost not miss a beat. In a DR test, we are more staging and moving systems over, and this is more of a tactical approach. With some of the moves that we are making with SQL and using blue-green environments, I don't think we see a problem at all. We feel very good about it. 

What's my experience with pricing, setup cost, and licensing?

We bought it through a reseller.

We are very fortunate because our budget is pretty big, and I am not making that up. Staffing may be a little thin at times, but as far as budgeting what we buy, the price for this solution has not been so outrageous that we don't buy it.

I think there is a support cost.

Which other solutions did I evaluate?

I was a big proponent of using SRM because I manage the VMware environment. Being a VMware product, I was more in their corner. So, it was mainly between SRM and Zerto. We also might have looked at Rubrik.

With other vendors that we used, we would sometimes start on the weekend, e.g., on a Saturday morning at 6:00 AM, then we would go through at least Thursday of the next week. It would be a long, arduous process. Sometimes, we would go only two days because we could never get past a single spot, then the entire test would be a failure. With Zerto, it has reduced our DR testing time drastically. It went down to where we think we can do a test in a single day. We were able to pull it off last year in two days with failover and failback tests as well as reports.

Zerto provides ease of use when building out jobs, then having them failover as you want, one by one or selecting five or six VPGs at a time. One of the big things that we do is with SQL. We want our databases online before doing any testing. There also needs to be domain controllers turned on for people to be able to log in. It is like, "Alright, we are going to fail over the domain controller." Next, they go, "Alright, we are going to fail over our SQL stuff." Before, when we had those SRM groupings, it would be a bit harder. You had to wait for everything to finish. Now, it is granular, where you can pick and hit one by one what you want. The database administrators can go in, and say, "Alright, we are online. There are three more that just came online." They are able to test it, and it just works. Having something that works was a big thing for us.

It has not replaced any of our legacy backup solutions. We use Veeam for any backups or system restores at this point. So, Zerto's role is just for DR.

We have luckily not had to use Zerto in a data recovery situation for ransomware. We have had one instance where we were in a spot like that, which was about two years ago, and we were able to restore it back with Veeam.

Until the last few cases, VMware support is some of the sorriest support that I have had.

What other advice do I have?

I would recommend Zerto because it works. You will need to do a PoC first though.

Immutable data copies are something that we are looking into. For example, if I have a recovery point of two, nine, or 10 seconds, then we get hit with some sort of ransomware attack or something like that. We would like to have immutable data that is unchanged. So, we are looking into this feature now.

I am sure it has enabled us to do DR in the cloud, but we are not a big fan of putting that stuff in the cloud. We are not a fan of putting it on somebody else's computer if we can put it on our computer. We have been very happy having a DR site approximately 150 to 200 miles north of our main site. We are kind of running it in our own hybrid cloud at the moment.

As far as testing, there are probably 70 people who test.

I would give it a nine out of 10. It has done what we wanted. We have been very satisfied with it. We are Zerto fans.

Gives us business continuity capabilities during hurricane season and in case of ransomware
Pros and Cons
  • "If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection."
  • "If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."

What is our primary use case?

We have two primary use cases. One would be to use it in reaction to a cyber-terror event, particularly ransomware, because Zerto has point-in-time backup. If we find an area that needs to be restored, as long as we figure it out within 24 hours, which is approximately the amount of time we have replicated, we can go back to a point in time. Let's say the files got encrypted at 9:30 AM. We can say restore our 9:29 AM copy of what the data looked like at that point. We have not needed to use that, thankfully, because we've been educating our users very well.

The other case that we would use it for is because we're in a hurricane area. Our particular office is actually in an evacuation area, typically, meaning that we're close enough to the coast that should a hurricane event come through, they generally force us out of the area. What we would do if we needed it, and thankfully we haven't yet, would be to shut down our primary on-prem services to make them a little bit more resistant to water damage. Obviously, if they're not running, they're a little bit less likely to get zapped if there is some water damage. Then we can bring up the copies that we have at our data center and run remotely from that if. It doesn't have a full copy of our entire environment, but it does have a copy of our ERP system, as far as sales are concerned. We wouldn't be able to ship anything, but we could look at orders and help our customers. We could even take orders if we needed to, although we wouldn't be able to process them.

Zerto is a replication solution. It copies our setup which is on-prem to our data center, which is also somewhat local, about 15 miles away. It doesn't really do anything in the cloud other than move data across it. We're not replicating to any cloud-based services like Amazon or Azure. Essentially, we're using it at two on-premises locations: Our primary location, which is what is being replicated, and the replicated copy is being stored at another on-premises location, nearby.

How has it helped my organization?

Zerto is purely a business continuity and disaster recovery tool. We don't want to have either one of our primary use case events happen, but if they should happen, it gives us an extra layer of protection. I've got Amazon backups with stuff in completely different regions, but Zerto is more for those two specific scenarios I mentioned. In addition, if somebody deletes a file and it's really important that they have the latest copy of it, Zerto gives us that option. But it really comes down to the ransomware reactions and the hurricane support, because hurricanes are fairly common in this area. The last hurricane event here was before I had Zerto and we had to shut everything down. We really couldn't do much while the hurricane came through. The business wanted something that would give us some protection in that scenario. That's the business continuity aspect. At least we can provide some business capabilities this way. With Zerto, they'll also be able to access a limited functionality version of our system. It definitely provides upper management with a little bit of comfort that we won't be completely down in either a ransomware or a hurricane event.

We're a smaller company. We're owned by a portfolio company, and they're the ones who made a lot of these extra layers of protection happen. Zerto provides me with the comfort of one of those layers. It enables me to make a strong case to my board of directors that, "Yeah, we're good." There's a guy in our board of directors who's something of a tech guy. I can look him in the eye and say, "Hey, we're not bulletproof. We can never be bulletproof, but we're about as close to bulletproof as we can be, especially for a company our size." That's important to the board because they have other companies that aren't as well-protected as we are. I've had conversations with a couple of the guys at those other companies, because they're interested in looking at something like Zerto, and I have been highly recommending it to them. It's a reasonable cost, it provides several layers of protection from ransomware, and if necessary, against natural disasters. I'm very happy to say that Zerto is one of those layers and provides us with very good protection for what it specifically does.

We had two ransomware events prior to being owned by the company that owns us now. Both were events where somebody clicked on a link that they shouldn't have and something ran and encrypted some of our stuff. Now we're much more solidly protected from that, and Zerto is definitely one of the big things protecting us.

If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection.

When you need to fail back or move workloads, Zerto significantly decreases the time it takes. As long as it's one of those scenarios in which we foresee using it, it's great. When we did our two failover tests, it was easy to failover to the other location where we have the replicated copies. The last time we had an actual ransomware event, which was before we had Zerto, it took me 30 hours to restore all the data that I needed to restore. I would imagine Zerto would take 10 to 20 percent of that time.

In terms of saving staff time, I only have three people on my staff, so I'm not going to save human resources by using Zerto. That being said, what it does save me is the trouble of having to use another solution that would take a lot of time. I only engage my guys who work on Zerto for six to 10 hours a year, versus having somebody on staff. That's a significant savings for us, because we don't need somebody on staff who knows how to do things with it. It is pretty easy to use for somebody who's familiar with it and uses it on a regular basis. For example, when I do the upgrade, I'll pay guys to do it because that's what they do.

We have secondary, older equipment where our Zerto backup copy resides. We moved that old hardware to our secondary location and got new stuff in our primary location. Our primary location now copies, via Zerto, to the other location that has our old equipment. It's not quite cloud, but it is in a different location. And it's definitely saving us money in the long-term by not having to pay for cloud storage because we have put it on our older stuff, and it works fine for that scenario.

We did a test turning it back on and rethinking it, and that took a reasonable amount of time. A lot of that is not actually limited by Zerto. It's more limited by your pipeline between your backup location and your primary location. Zerto was very helpful, and it's very easy to use from that standpoint. Once you reconnect the two sites, it does a snapshot check of where it left off and then it copies back over the changes that happened while it was running on your secondary site. That's not automatic. You have to touch it. But it's certainly not super-technical.

What is most valuable?

Our two primary use cases are Zerto's biggest features for us. That's what we use it for. There may be other situations where it can come in handy, but those are our two primary scenarios.

In terms of providing continuous data protection, Zerto has been great so far. Thankfully, we haven't had an event where we have really needed to rely on it, but we have done a couple of tests prior to hurricane season where we disconnect our primary facility. We then go over to our secondary facility where the replicated data is and we bring everything up and then we do remote access to that location to make sure that it's all working properly. It's very capable. I've also done a couple of test scenarios on ransomware reaction where I'll go in and restore a folder, after hours when nobody is in the system, to emulate a situation where we might need to go back and restore kit encrypted files. So far, it's been great.

Regarding the ease of use, there's a web portal that I use to verify that everything is working well. It has a lot of notifications and it emails me if there's anything going on that's out of the ordinary. For example, if the connection to one of my other sites goes down, it will let me know that it's not able to reach that site. I'm very happy with the way the interface works for my needs, and my tech has been pretty happy with it. Our installation is rather small. We only have 14 servers on it. I'm sure there are other companies that have hundreds, but I imagine that they would see the same capabilities. The web portal is pretty well organized and easy to navigate.

For how long have I used the solution?

I have been using Zerto for just about three years. We just re-upped the maintenance on it and, until that point, we had a three-year plan for it.

We're on version 7.5, but I've had some discussions with my partner where we have the replication stored. We're doing an upgrade, but we ran out of time before hurricane season so we decided to hold off until after that. We're going to move up to 8.5 as soon as hurricane season is over, but I didn't want to risk getting into a situation where we didn't have Zerto working at all. And version 7.5 has been working fine. There was no real need to do the upgrade, other than to stay current.

We're about a version behind. I generally stay at least a half-a-version behind to let everybody else do all the sorting out of anything that they might find with the new versions, and then I jump on the second-oldest version, once that's a little more mature.

What do I think about the stability of the solution?

The stability of Zerto itself has been fine. We have some network instability that affects it, but I see the alerts come through and it's not Zerto that is having trouble. Zerto itself is very stable.

What do I think about the scalability of the solution?

Scalability is not really applicable to our situation, but I would imagine that it would be easy to scale if needed. We would just buy additional licenses and strategize a little bit about how we were going to add them.

We only have 15 server licenses, but I expect we'll have some growth as we have a couple of projects upcoming. We're probably going to need another server, so even though we're retiring a few servers, I'll leave the licenses. I won't probably be in any position to make it bigger any time soon, but you never know. Our company always has its eye out for acquisitions. Last year we picked up two companies, although they didn't really result in any major increase in our infrastructure. Maybe we'll pick up somebody similar in size to us and all of a sudden we'll need to protect 10 more servers. I don't have any plans for downsizing Zerto.

How are customer service and technical support?

If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away.

I've only had to deal with their tech support a few times, and I would give them a nine out of 10. They've been pretty responsive. They've answered my questions. They've gotten things taken care of.

Which solution did I use previously and why did I switch?

Before Zerto, I just restored backups. We have Veeam as our primary backup system. Veeam is a traditional backup system. In those ransomware events I mentioned, I literally had to go through and restore a bunch of stuff from different servers from our backup repository, which is onsite. I had to go back and restore this folder and that folder and this folder and that folder. I would sort of have to do that with Zerto, but it would be a lot easier. I could just pick the folder and pick the time, and say, "Go." With Veeam it was definitely a much more complicated process.

We didn't "switch" to Zerto, we added it. We still have our other solution. While there is disaster recovery where you're recovering from a disaster, business continuity is how fast you recover from disaster; how quickly you get the business going again. Zerto reduces our RPOs. It was more a case of added protection and it reduces our recovery times—even though thankfully we've never had to use it—compared to the last time we had to recover.

Zerto came highly recommended from our primary VAR, which is Presidio, the place we bought it from. They said it would do exactly what we needed it to do, and the price was reasonable. I took the recommendation, did some research on them. It's possible I looked at reviews on IT Central Station and someone there said, "Oh yeah, Zerto is great." That's good enough for me. I didn't need to spend a ton of time on it. As long as they've got good reviews from multiple sources, which I did find when I researched Zerto, and it came highly recommended from our VAR, those were two pros and I didn't need to go looking for a con.

What about the implementation team?

I didn't actually set up the software. I had to pay somebody else to do that because it was a little beyond my team's capabilities. Our deployment took about six hours from start to finish. The guy that I worked with said that he was pretty happy with it. He had to send in a couple of help tickets, and they were very responsive and were able to help him get through the issues that he had.

He's from an IT support firm called Creative Network Innovations, and they also have an onsite data center, so they offer data center support services in addition to regular IT support services. In this case, Zerto is data-center related. We use Creative Network Innovations because it's related to what they do for us, and they have people on staff who are comfortable working with it. Even though they don't necessarily do Zerto all the time, they were able to step in, take a look at it, and sort it out for us, so that was good.

I wouldn't necessarily say that they're experts in the software, because they learned it for us. They're not typical Zerto implementers, but that speaks to how easy Zerto is to use. They had never really used it, but they were able to pick it up, plug it in, and get it working for us.

In terms of deployment time, the Zerto piece didn't take long. It was about six hours. What we had to do in terms of setting up networking, that was a little different. The whole project, including Zerto, took about 12 to 16 hours. And when we did our first failover test, that probably took another six hours, because we had to figure out all the nuances of how to make it handle the various servers that we have.

It depends on the size of your installation. Because we're fairly small, it didn't require a lot of involvement. Most of it is Windows-based, so it's not that hard to install and set up. Things like getting access through the VPN, which weren't necessarily Zerto-specific, are what took a little time, but the Zerto piece was pretty fast.

It's a backup piece for us. We didn't really get that fancy. We basically identified the servers we needed to replicate offsite. Then we installed Zerto on our primary location and we installed Zerto on our secondary location. And we created the communication.

In terms of users, I'm the only one in our organization who monitors Zerto, and I do very little of that.

What was our ROI?

I would estimate that if I had to recover from a scenario like the last one that affected us, it would take me 10 to 20 percent of the time it took me at that time. That reduces the amount of time that our system is down and, therefore, the amount of money we're losing because our system is down. It does provide some cost-benefit, but it's hard to quantify, because nobody has said, "In our company, we lose $X an hour when we're down." But when things are down, people are not happy. If nothing else, it means I hear less griping, and that makes me happier.

What's my experience with pricing, setup cost, and licensing?

They have an enterprise-type of licensing scenario, which we didn't qualify for because we don't have enough. Ours is pretty straightforward. It is site-based, but the payment concepts are based on the number of servers. In our case, we have a quantity of 15. When we bought it, there was an initial purchase amount plus maintenance. When it came up for renewal, we did three more years, and it was under $10,000 for my 15 servers.

It's very reasonably priced. It's a little more than $3,000 annually. That works out to about $20 per server per month.

Which other solutions did I evaluate?

Our backup recovery software, Veeam, is working on a product that will compete with Zerto. But it's still very new. It has not been out for very long, so I don't anticipate us going away from Zerto any time soon. That being said, when our renewal comes up with Zerto, I might reevaluate and look at Veeam and see if their solution is going to cover what Zerto does, because then I have one vendor to deal with, not that I dislike dealing with Zerto. It's just sometimes it's nicer to put all of your stuff into one package because the interfaces are uniform.

At this point in time, Zerto is safe with us. We've got them for three more years, and it does exactly what we need it to. Is it going to be our daily backup and our long-term retention? At this point in time, no. I'm pretty happy with what Veeam does and how it integrates with VMware, not that Zerto does a poor job. Zerto covers a different area.

It's kind of like if you were wearing armor, as a knight of old, but you were missing a piece on your back. If somebody stabbed you in the back, if you had armor there, you wouldn't worry about it. Zerto covers our "back." It covers stuff that Veeam doesn't. It handles point-in-time backups and it gives us a faster recovery in certain scenarios. It's not going to necessarily protect us from a full on-premises failure, because I don't have it doing that. I bought it specifically to defend us from certain types of attacks. We have Zerto handling 14 servers but we have a total of 20 servers. It's not backing up the other six, Veeam is, but that's because I don't need those to be protected from ransomware. I need them to be protected from system failure or catastrophic disaster where our primary location is under 20 feet of water from a hurricane, or the whole thing burns down. Zerto is not going to protect us from that, although it possibly could. We just don't use it for that.

It provides us some niche protection and we're happy with the niche that it protects.

What other advice do I have?

Because we're a smaller company, I would never need a full-time person to do disaster recovery, whereas a company with several thousand employees and multiple billions of dollars of revenue would probably have a team for that. I would imagine those guys would save people if they had Zerto, but that's just me imagining that, rather than it being fact.

If I had 1,000 servers, it might require more of my time, but we have 14. We have a board of directors that wants things to be bulletproof, and they're willing to pay for it. Do we need Zerto? Probably not. Is it nice to have? For sure. But we certainly don't use it in the typical use environment, which I'm sure is a lot more servers than we have. That being said, we still use it, and I highly recommend it, even for companies of our size, although it's probably not the sweet spot for a lot of companies like ours. It's kind of pricey for smaller companies, but for what it does, I think the value is exceptional.

For companies of our size, if you don't have somebody on staff who can use Zerto, you want to find the right help. Your VMware person should be able to help you with it. Make sure that you're comfortable with what you're trying to accomplish. I thought it was a pretty smooth implementation, as you can tell from the time that it took. That might be in part due to the people we enlisted to help us. I can't say that everybody's installation will go that smoothly, but I would imagine that if you have a pretty solid VMware-type person, you should be pretty good with the Zerto piece. It's really a matter of working on the VMware side of it. There is also a little bit of networking, depending on where you're backing up to.

If you're backing up to the cloud, you obviously need somebody who is cloud-savvy who can get the proper connections to your AWS and secure them.

Overall, make sure you have somebody who is VMware-savvy. You don't necessarily need somebody who is specifically Zerto-savvy. The guys that I worked with said that it was pretty easy to work with, even though they hadn't worked with it before. But again, ours was a smaller installation. A Fortune 500 company is going to need a little bit more capability. They're going to want to look for a Zerto-certified implementer, which I presume there are. We didn't bother with that because we're smaller and we didn't really have anything particularly difficult in our implementation.

In terms of preventing downtime, in our situation Zerto hasn't helped reduce that, but it's not because Zerto is not capable of doing so. It's just that we haven't had a situation like that in which it has needed to be used. We haven't had any incidents that required the use of the Zerto fallback.

The biggest lesson I've learned from using Zerto is that I wish I had known about it six years ago. I wish that I had known about its capabilities. Given that it's on version 8.5, it's been around for a while. I really wish we would have had it when we actually had a need for it.

If we ever need it, we're confident in it, given the test scenarios we've gone through where it's been great. It's a nice "warm blanket," and it's good to "cuddle" underneath it, because I don't have to worry about it. If I have an event, I'm pretty confident that I can get us back up and running quickly. Is it going to be instantaneous? Of course not. But it's going to take significantly less time than it would take if I had to react via a manual backup.

Zerto is "the bomb." I'm definitely happy we got it. Overall, it's reasonably priced. It's one of the less expensive business continuity and disaster recovery layers that we have. That being said, it doesn't do everything. We're a smaller shop. There are only three people on my IT team, including me. It's definitely been a very helpful tool and comforting to know that we have it in place. It makes it easier to sleep at night. For what we need it for, it does everything we need.

Zerto is a nine out of 10 and maybe even close to a 10. It's solid. It's a good product. It does what we need it to do. Since we haven't actually had a live event, I can't say that it's perfect, but in the tests we have run it through it has been great. The only blemish has been dealing with the account manager, which could be situational. I've only had to deal with him a few times. The last time he didn't even respond to me. That being said, it's been three years, and maybe he's moved on and nobody is monitoring his email box. And when I reached out to support, they took care of me right away. So the account management is a minor blemish. Everything else, as far as the product and support go, has been fantabulous.

Is user-friendly, saves us time, and costs
Pros and Cons
  • "Zerto's most valuable features include its user-friendly interface, multi-tenancy capabilities, and near-zero downtime recovery."
  • "We encountered some issues during Active Directory recovery."

What is our primary use case?

We utilize Zerto as part of our disaster recovery toolset. We employ a multi-tiered model, catering to a select group of customers, primarily hospital clusters. These customers maintain on-premise networks with cloud-based disaster recovery. In this managed service offering, we leverage Zerto to facilitate their cloud recovery.

How has it helped my organization?

The replication is quick. We encountered some challenges replicating the data during the first full copy. Since we weren't using Zerto, I suspect the bandwidth requirements for replication were a bottleneck for us. However, once the initial copy was complete, the process became seamless. The recovery was near zero after the first replication. Zerto worked perfectly.

We implemented Zerto because it supports a multi-tenant model, which was a critical requirement for us. We have five tenants located on-premises across five different data centers. However, we only have a single disaster recovery site in the cloud. Zerto's solution enabled us to consolidate our disaster recovery needs. Previously, managing five separate data protection solutions for each data center and five different cloud recovery subscriptions would have been incredibly expensive. Zerto significantly reduced our costs. Additionally, Zerto provides a single-pane-of-glass dashboard, allowing us to manage our infrastructure efficiently and effectively. This comprehensive view offers full control over our applications and complete visibility into all our tenants. As an infrastructure manager, I believe these features are the most valuable contributions Zerto has made to our organization.

Zerto has helped save around 30 percent of our time.

Zerto has helped achieve significant cost savings.

In the VMS portal, we had a relatively small amount of data overall. We also had multiple tenants, each with a maximum of 20 to 30 virtual machines on-premises. These VMs weren't particularly large. As a result, recovery was quick, typically taking less than a minute. My Recovery Time Objective would be less than a minute for any VM, even for a complete migration of all on-premises VMs to the cloud.

While I wasn't privy to the details of the client's previous DR solution before implementing Zerto, our discussions revealed significant time savings with Zerto's recovery process. Compared to their prior on-premises DR approach, Zerto offers a substantial reduction in recovery time – at least 15 to 20 minutes faster. This improvement stems from eliminating the need to coordinate with personnel and the time required for on-premises recovery procedures at their dedicated DR site. Previously, they relied on manual, on-premises to on-premises recovery, which inherently took longer. However, a direct comparison between their old solution and Zerto wouldn't be entirely accurate. Zerto offers significant efficiency gains, boasting up to 200 percent improvement.

Migrating data through Zerto is straightforward with careful planning. Our first experience involved Zerto's support throughout the process. While initially challenging due to our lack of experience, we were able to navigate the initial setup. One hurdle we faced was optimizing network traffic for the initial data replication from on-premises to the cloud. However, we embraced the learning curve, documenting everything as we gained control of the environment. This ensured a smooth integration for subsequent tenants. While the first migration presented some difficulties, as is to be expected, Zerto's excellent support made the process manageable. Their responsiveness in explaining and resolving issues made it a positive experience overall.

The RPO was very close to zero, meaning there was minimal data loss between replications. However, this could be impacted by the specific database being hosted and other factors. For application servers or virtual machines replicated on-premises to the cloud, I believe there was negligible lag or delay, assuming no network issues. Bandwidth and network traffic did play a role – we observed instances of slower RPO due to traffic spikes or network events. However, with Zerto providing the recommended data bandwidth, we encountered minimal challenges. In most cases, I'd say 90 percent of the data was synchronized almost constantly. The only exception was when network issues arose.

Our data center experienced an issue, necessitating a disaster recovery procedure. Fortunately, data loss seems minimal, and the impact on our clients appears negligible. This is partly due to the managed service we provide for a tenant, who fortunately didn't perceive any significant data loss. The success of the recovery is also attributed to our user-friendly, always-in-sync system. Upon receiving alerts and notifications, we promptly informed the client, who then quickly authorized the recovery process. From our perspective, the recovery went smoothly with minimal challenges. In the actual scenario, we believe data loss was negligible. While some data loss might have occurred technically, it wasn't significant enough to cause any noticeable impact on the client. It's important to note that our monitoring team maintained complete control of the situation, allowing for swift decision-making and a speedy recovery.

In a data recovery scenario, we'll still have our database administrator, Linux administrator, storage administrator, and Zerto operator available. While Zerto can automate disaster recovery and VM restoration, it's important to remember that it's not a foolproof solution. Even though Zerto streamlines the process, a well-prepared organization will always maintain backups and ensure a dedicated team is in place for data recovery. Zerto doesn't reduce the number of personnel involved; rather, it enhances their productivity by freeing them up for other tasks during a recovery event. During a recovery, it's still recommended to have everyone on call. While Zerto handles most recoveries, there may be situations where manual intervention is necessary. By being fully prepared, our organization can effectively address any data recovery situation.

It is easy to manage and monitor the DR plans using the Zerto GUI. 

What is most valuable?

Zerto's most valuable features include its user-friendly interface, multi-tenancy capabilities, and near-zero downtime recovery. Zerto is easy to learn and use, even for those with limited technical experience. Additionally, Zerto's failover testing functionality allows us to run tests in real time without impacting production systems.

What needs improvement?

We encountered some issues during Active Directory recovery. When we implemented Active Directory, we provided feedback to Zerto regarding the challenges of recovering AD from the on-premises environment to the disaster recovery site. Unlike other virtual machines, AD recovery presents unique difficulties due to its active-active nature. It's unclear whether these challenges stem from Zerto itself or limitations within Microsoft Active Directory. However, in our experience using Zerto for AD recovery compared to other technologies, we faced data discrepancies that necessitated workarounds to bring AD online at the DR site.

Certain applications we migrated from production relied on Active Directory authentication. To ensure successful application functionality at the DR site, a functional AD environment was a prerequisite to application migration. Therefore, our initial step involved copying and guaranteeing a running AD instance on the DR side before application recovery.

However, upon attempting application authentication on the DR side, data inconsistencies prevented successful authentication. To address this, we created an isolated clone of the AD environment and conducted tests. Through trial and error, we were able to develop workarounds to resolve the issue. Notably, these challenges were specific to Active Directory; other VMs didn't exhibit similar problems.

For how long have I used the solution?

I have been using Zerto for over 3 years.

What do I think about the stability of the solution?

Zerto has been very stable for us. We do apply patch releases and upgrades whenever necessary to ensure continued stability. Fortunately, we haven't encountered any major bugs or issues that would cause significant downtime, unlike what we've experienced with some other tools. Zerto has been a reliable choice for us.

I would rate the stability of Zerto 9 out of 10.

What do I think about the scalability of the solution?

I would rate the scalability of Zerto nine out of ten.

How are customer service and support?

The technical support is fantastic. They offer same-day assistance, and their documentation is clear and comprehensive.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

Before implementing Zerto, the client's disaster recovery relied on an on-premises to on-premises failover strategy. Seeking a cloud-based solution, they chose Zerto to leverage its expertise in this area.

We previously used another tool for DR orchestration. While Zerto can also perform recoveries, it focuses on virtual machines and doesn't extend to the operating system or database level for starting and stopping applications within those VMs. Despite these limitations, Zerto excelled in its support. The Zerto team provided excellent assistance whenever we faced challenges, joined calls to help us troubleshoot, and offered clear timelines for resolving issues. Their documentation was also thorough. In contrast, the previous DR tool lacked comparable support and documentation. This stark difference in support quality is why we favored Zerto and ultimately removed the other tool from our project. Currently, we rely solely on Zerto for our existing tenants, and we plan to continue using it for future ones as well.

How was the initial setup?

We encountered some challenges during the initial setup. Zerto offers several data replication options, I believe 2 or 3. These include copying data to our hard drive or storage box, copying it to the DSR site, and replicating it over the network. However, only network replication worked for us.

The issue might have been related to bandwidth requirements. It's possible that either Zerto itself or our network infrastructure wasn't up to par. We faced some challenges during that initial phase.

However, after the initial setup and the application of delta copying, which happens daily, we rarely experienced any replication issues. Most of the time, network glitches and fluctuations caused brief disconnections, but overall, replication ran smoothly.

We went into the Zerto deployment with a clean slate. Both team members were new to Zerto, so we were all learning as we went. This initial deployment was challenging, but it gave us valuable hands-on experience. Once we had a firm grasp of the environment, onboarding subsequent tenants became seamless. We developed a clear plan and approach, which streamlined the process for future deployments. Technically, the challenges weren't ongoing. The main hurdle was understanding how to integrate Zerto with our existing infrastructure. While that initial learning curve was steep, Zerto's excellent support helped us navigate it successfully.

The deployment time for Zerto varies depending on the complexity of your environment. More complex environments will require a longer replication process. However, on average, we can onboard a new customer within 1 month. This timeframe encompasses the entire process, from the initial planning phase to the deployment of up to 30 VMs within a tenant.

Our project involved 2 separate IT teams at 2 different locations. One team acted as the managed service provider, while the other represented the client side. The client-side team, located on-premises, provided us with essential information about their data centers. This included details on virtual machines, such as their size, quantity, and basic data collection metrics. They also helped us identify their storage requirements. Based on this information, we planned our cloud storage procurement and other necessary actions. The project team comprised approximately 10 to 15 people, including project managers, IT personnel, storage specialists, network engineers, and development experts.

What other advice do I have?

I would rate Zerto 10 out of 10.

Our organization uses Zerto to manage the replication of data centers from 7 on-premises locations to the IBM cloud for our midsize clients.

Our environment consists of VMware, data storage, and a network, with Zerto deployed for disaster recovery. While VCDM and VMware are managed by our cloud provider, we maintain 5 additional technologies with a team of 8 people.

We experienced a brief on-premises outage. Fortunately, we were able to recover quickly using Zerto. The software triggered an alert, notifying our monitoring team. These features proved to be very helpful. Additionally, we were able to promptly contact our clients and explain the situation. They responded quickly and effectively, minimizing the impact on their end. Our clients were pleased with the response.

I recommend Zerto to others.

Instead of one mass disaster recovery exercise, we're easily able to perform up to 12 in the year
Pros and Cons
  • "In situations of failback or moving workloads, it saves us hours. If I were to have to move a four or five terabyte machine using something like VMware's virtual copy it has to install on the machine and copy the data over. Then it has to shut the machine down and do a final copy, which means there's a lot of downtime while it's doing the final copy."
  • "The interface is the only thing that we've ever really had an issue with. It's gone through some revisions. The UI, it's not clunky, but it's not as streamlined as it could be. Some of the workflow things are not as nice as they could be."

What is our primary use case?

We use it for disaster recovery and to migrate machines from one location to another.

How has it helped my organization?

The big thing for us was our disaster recovery. At that point, we were only able to do a disaster recovery test once a year. Now, we officially do a disaster recovery test once a quarter and we do a subsequent test once a month to verify that it's doing what it's doing and the IP address is changed. Instead of one mass disaster recovery exercise, we're easily able to perform up to 12 in the year.

It allows us to verify in a much more granular aspect whether our data is being migrated or not. Once a year, if we find some issues, we're at least 11, 12 months behind at that point. Every 30 days, if we do a test and we find an issue, we're able to correct that. The time between tests is shorter, which means that if there is a problem we're able to resolve it in a much shorter amount of time versus an entire year, and then waiting another year to see if everything is working again.

When we need to failback or move workloads Zerto decreases the time it takes and the number of people involved. We are able to put a machine into Zerto, let it do its magic in migrating the data from one side to the other. We've had instances where we've got machines that are four or five terabytes that we can move from one side to another after it's done synchronizing in 15 minutes or less. Sometimes it takes DNS longer to update than it does for us to move the machine.

Instead of me having a server person, a network person, and a storage person, I can put it into Zerto, let Zerto do its job, fail it over, and then just have the application owner verify that the server is up and running, and away we go. So on a weekend, I don't have to engage a team of people, it can just be myself and one other person to verify that the machine is up and running. It really cuts down on overhead for personnel.

In situations of failback or moving workloads, it saves us hours. If I were to have to move a four or five terabyte machine using something like VMware's virtual copy it has to install on the machine and copy the data over. Then it has to shut the machine down and do a final copy, which means there's a lot of downtime while it's doing the final copy. As far as downtime from an application standpoint, with Zerto, we're from hours down to minutes, which is great when you have applications that are supposed to be the five nines of a time kind of thing.

We have not had any ransomware issues. But we have had an instance where somebody installed something that messed something up. It was a new version of Java and we were able to roll back. Thankfully they realized it fairly quickly because we only keep a 12-hour window. We were able to roll back to almost a per minute instance prior to that installation and recover the server in minutes. Our backup was as of midnight, but they did it at 8:00 in the morning. So we didn't lose eight hours' worth of processing.

If we were going to use our backup solution, it would have taken minutes to restore the actual server, but then from an SQL perspective, we would have had to roll the transaction logs from backups. I couldn't even tell how long that would have taken because we had to do all of the transaction logs, which are taken every five minutes from midnight, all the way to 8:00 AM in five-minute increments. It would have taken considerably longer using traditional methods versus Zerto.

Although it hasn't reduced the number of staff involved in overall backup and disaster recovery, what it has allowed us to do is actually focus on other things. Since Zerto is doing what it's doing, we're able to not have to stare at it all day every day and make sure that it's working. We have the screen up to make sure there are no errors, but we're able to focus on learning how the APIs work, working on the other products that we own for backup and storage. That's mainly what my group does, we do disaster recovery and storage backups. We have six pieces of our enterprise and before it was just the main piece that we were working on. Now, we're able to actually work with the other five or six entities and start doing their backups and disaster recovery because we have a lot more time.

What is most valuable?

The failover capabilities are definitely the high spot for us. Previously, when we did disaster recovery it would take us easily a day or two to restore all of our servers. We can do the same thing with Zerto in about an hour and a half.

We're about six or seven seconds behind our production site and it does a really good job of keeping up, making sure that we're up to date. That's one of the other things that we think is just phenomenal about the product, we're able to get in there and put a server in and within usually a few minutes we're protected. Six or seven seconds behind is a pretty good RPO.

Currently, we are using another product for longterm retention, so I don't think we really have any plans on switching over at this point.

Zerto is very easy to use. We did a proof of concept and it took longer to build the Windows servers that had to be installed than it did to actually install it and roll off the product. Our proof of concept became production in minutes.

What needs improvement?

The interface is the only thing that we've ever really had an issue with. It's gone through some revisions. The UI, it's not clunky, but it's not as streamlined as it could be. Some of the workflow things are not as nice as they could be.

I like the fact that Zerto does what it does and it does it very well. I have had Zerto since version four, so the longterm retention and things like that were never a part of it at that point. I just like the fact that I can install it, I can protect my virtual machines, and I'm comfortable and confident that it's doing things correctly because of the amount of testing that we've done with it.

For how long have I used the solution?

We have been using Zerto for a little over three years. 

What do I think about the stability of the solution?

It's very stable. Once a month we verify that the internal mechanisms of Zerto are working. When I do a test failover we check if VMware tools come up, if the IP addresses change, and the things that Zerto is configured to do automatically. Usually, if there's an issue, it's either I did something wrong when I configured it, or I put in the wrong IP address or the VM itself has an issue, the tools aren't loading correctly or at all, or it was trying to do an upgrade and failed. We've actually been able to identify other issues inside the environment that we would not have realized were an issue by doing these tests.

What do I think about the scalability of the solution?

Our next step is not so much increasing the capacity but protecting things to the cloud. We'd like to be able to take those same 350 machines or so do we have, and definitely, if not the important 50 that we have, but all of them, have them not only go to our disaster recovery site but also split to AWS. It's where we have both of the sites, one in one location and one in a vastly different location and if for some reason, one were to go offline, we would have those objects in AWS to be able to spin up and do what we need to do.

We ramped up from that 50 to 350 within a year and Zerto just took it and kept on running. We are still about the same RPO as we were before, we're protecting 60 plus terabytes of data at this point with those 350. It did what it had to do to create new virtual machines, depending on how many disks there are. I think that I was able to scale with our needs really easily. 73 terabytes are what we're protecting right now across 357 VMs, and we have a seven-second RPO. It went from a small number to a very large number. The issues that we've had around Zerto protection has either been that networking wasn't sufficient, or the storage itself had to be increased.

There are three of us who work with Zerto, that's it. We do contact other teams, often our networking team to get an IP address for something. But when it comes to doing the testing, when it comes to doing the implementation, and when it comes to doing verification processes, it's all my team of three people.

I am the data management supervisor and then I have a lead storage administrator and a senior storage administrator.

Which solution did I use previously and why did I switch?

Prior to Zerto becoming our disaster recovery product, we were using Dell EMC's Avamar for backup recovery and for disaster recovery, which we quickly realized was not going to work out very well. We used it for about four or five years. When your disaster recovery test is five days and you take one and a half to two days to do restores only, that doesn't leave a lot of time for testing. Now, we're able to do the restore in an hour and a half. Then we actually can start testing the exact same day that we did the restores. In most instances, we're able to actually finish everything within 24 hours.

When we first purchased it, the backup portion did not exist. So having backup and DR in one platform really wasn't that important to us. We use Rubrik for backups and longterm retention at this point. We really don't have any intent on using Zerto for longterm retention, as we're extremely happy with Rubrik. But time will tell if we decide to switch over to the LTR portion of the product.

Compared to Avamar, Zerto is extremely easy to use. I can bring Zerto up and start recovering, failing over, or testing machines before I can even log into Avamar. Avamar was very clunky from its interface. It's very easy for Zerto to go in and recover a machine to a certain point in time. Where moving around in Avamar, since it was Java based, would take quite a long time to get from screen to screen. And the workflow was not user friendly at all.

We have different use cases for Zerto and Rubrik but I think that the interface and functionality, as far as what I get out of that particular product, what its purpose is, they're both about on par. Honestly, we've told both companies before, we would love for one to buy the other so that we can get the best of the disaster recovery with Zerto and the best of backup and recovery, longterm retention type things with Rubrik. Because they definitely are probably the two best products for their market segment.

Replacing Avamar has saved us on the cost needed to manage them. As far as management goes, we still use the same three people. But as far as renewal maintenance costs, definitely. Dell EMC is very proud of their products and their renewal maintenance costs were rather large compared to what we do with Zerto.

Initially, we saved about $1,000,000 three years ago by switching to Zerto. Zerto and Rubrik replaced Avamar. But buying both products together, versus what the renewal/upgrade costs would have cost us for Avamar, with all the hardware, was a savings of $1,000,000.

How was the initial setup?

The initial setup is very straightforward. I built a couple of virtual machines to run the manager on, deployed some VRAs, and then attached it to VMware and checked what I wanted to protect. We probably had it up and running in about an hour total. Then we tested protecting some machines, and we had some test boxes that we tested back and forth. It was a very easy setup. People are definitely sold about how easy it is to install and configure.

Initially, our deployment strategy was to protect a small subset of very important machines for an enterprise. And then once we saw how easy it was to implement, how easy it was to put things in there, and how easy it was to protect them, it went from a handful of machines to 350 or so. The initial intent was to protect a very small number. That went from that to a very large number very quickly. Zerto was able to handle it no problem. We actually had to end up buying more storage on the target side because we had not planned on doing that many machines from the initial implementation.

What about the implementation team?

We worked with our account team. We were able to get the proof of concept software, a link to download it. They gave us a key, they gave us a little Excel sheet stating how many machines and IP addresses we needed. Then they basically sat on the phone with us for the hour with WebEx. And we set it up just that moment. That's really the only implementation help that we've ever gotten from them. Everything else has just been pretty much us on our own.

Their support has been very, very good. We've had some technical issues that we've been able to work through with them. Nothing major, but if I have a question or if we run into an issue, we're able to either open up a support ticket and they respond fairly quickly, or we are able to do some searching in their knowledge base. We've had an instance where we did the upgrade to a new version and it caused some problems. But within, I'd say a few hours, we were able to correct it because they had already experienced that. And they had that logged in their internal database of issues. So, they were able to log in, and give us the fix that we needed and get us back on track.

What was our ROI?

It definitely is a very robust product. The feature set from 4.0, 4.5 to now has increased greatly. We do like the fact, even though we're not using it, that as long as I pay my maintenance when the new features come out like longterm retention, analytics, the monitoring, the reporting, the things that were not there when we first purchased it that are there now, is all part of maintenance. It's not a bolt-on price. They don't charge extra. It was one of the things with Dell EMC that was always a pain was. They had additional costs. With Zerto it's like, "You paid your maintenance, here's a new feature, enjoy!"

What's my experience with pricing, setup cost, and licensing?

They have licensing breaks as far as 50 users, or 50 VMs, 100 VMs, 250 VMs. We ended up with a bunch of 50 at first, and all of our maintenance renewal dates were all different. It ended up costing us more because we didn't just make the investment up front to say that we wanted 250. We had to end up going back and resetting all of our maintenance dates to the same date. It was just a nightmare for our maintenance renewal person. If you did a proof of concept and you like it, definitely make the license investment upfront. That way, you're not trying to piecemeal it afterwards.

Licensing is all-inclusive, there are no hidden fees.

Which other solutions did I evaluate?

We looked at RecoverPoint for VMs. A long time ago, one of the companies inside this enterprise had used RecoverPoint and it worked really well when it was the physical RecoverPoint. But as things became more virtual, it no longer was as good as it had been, so they had discontinued it. RecoverPoint for VMs was definitely not as easy to set up. It was not as easy to use. It took a lot more resources. This is three-year-old information, but I feel like we would have had to have had more people on our team than we do now with just the three of us. We didn't feel like it was as stable. It certainly wasn't as easy to use, test, or get to work as Zerto was.

What other advice do I have?

My advice would be to do the proof of concept. They're very willing to help you with the installation. Do a proof of concept. If you're not amazed by it, I would be surprised. Everybody that we've ever talked to about this and have done a test of it says, "I can't believe it's just that easy."

I would rate Zerto a ten out of ten.

Real-time information through the portal helps with security
Pros and Cons
  • "The portal is a valuable feature. I am here in Baton Rouge, and I can get into the Vegas data center and see real-time replication on the portal."
  • "We have kept renewing Zerto because it seems to get better."
  • "I always get some blowback about the cost. It does not seem too bad to me. We had to upgrade to a premium subscription to get some other features. Maybe a one-size-fits-all option would be better."
  • "I always get some blowback about the cost."

What is our primary use case?

We use it in our data center. We have two data centers, one in Baton Rouge and one in Las Vegas, and we use it for replication. It is all used in the data center.

How has it helped my organization?

We did not have replication previously. Once we got Zerto, we started seeing everything backed up and replicated, and we saw its benefits pretty early. Over the years, we have kept renewing Zerto because it seems to get better. There have not been any issues with it.

Near-synchronous replication works very well. We use pretty big storage with them and never had a problem. If it is close to going over, we always get an email, and it is easy to keep up with all that, which is pretty important here at Credit Union. I have nothing but positive to say about Zerto.

Zerto is easy to use. When we first started using it, we used the emails they sent at the end of the night to see everything was fine. About five years ago, they got their own portal. Since then, we have been able to see everything in real-time. It has been super easy. I automatically get notifications on my phone or email. That has been a real high point for me with them.

We have several VMs, and Zerto has been a part of the protection plan for them.

Knowing what is going on in real-time has helped with breaches and things like that. Recently, there have been no issues. Luckily, over the last year or two, we have not had any security issues. Zerto and VMware are what we count on in our data center. As long as the data center is up and running safely, we are good here at the branch.

We run reports on XDR and get an idea of anything that has been going on. Luckily, we have been safe for the last year or two, but in 2022, there was an issue. Zerto was right on it, and we were able to get it cleaned up. Zerto has definitely helped in the ransomware aspect.

What is most valuable?

The portal is a valuable feature. I am here in Baton Rouge, and I can get into the Vegas data center and see real-time replication on the portal. The portal has been upgraded over the past several years, and it is probably the most helpful part of it.

What needs improvement?

I always get some blowback about the cost. It does not seem too bad to me. We had to upgrade to a premium subscription to get some other features. Maybe a one-size-fits-all option would be better. 

For how long have I used the solution?

I have used Zerto for eight to ten years.

What do I think about the stability of the solution?

I have not experienced any stability issues. We are a heavy usage bank, and it has always been steady for us. I do not have anything bad to say about that.

What do I think about the scalability of the solution?

Scalability has been good too. We started with the one in Baton Rouge and added the one in Vegas about five years ago. It was very easy to connect them and get them mirroring each other. Scalability has been good for us.

How are customer service and support?

When my staff member went to Vegas, there were some issues with logging into the device. He called the tech line and was able to talk to someone. We have had luck getting in touch with those guys. Their customer service deserves a good score, at least an eight out of ten.

How would you rate customer service and support?

Positive

Which solution did I use previously and why did I switch?

At the previous bank, it was a big Cisco shop, but I have been here for almost ten years, and we have had Zerto for that long. Zerto is what I am used to.

How was the initial setup?

I did not personally do the initial setup. A guy who works for me went to Vegas, called it in, and got it set up pretty well. I do not go to Vegas much, but I have been to Baton Rouge. I have tested it and played with it, and every time I have done that, it seems easy to use. My network administrator has never complained about any difficulty. For the most part, it is easy. They have a good tech support line, and if we have any trouble, they are easy to get in touch with. We are happy with that.

We have a maintenance contract with them, but I did not have to use it except for one instance a few years ago when we thought that we were going to get ransomware. We had maintenance on that. The good thing is that it is a part of the renewal. It is safe to have it, but luckily, we have not had to use it over the last few years.

What's my experience with pricing, setup cost, and licensing?

Price-wise, it works fine for me, but my budgetary team is always looking for ways to cut costs, and it seems like they first look at the data center and the IT side to find savings.

What other advice do I have?

Take advantage of the maintenance plan; even if it is not required, it is definitely worth getting. The techs there are really good. There are local Zerto reps who come around. Use the tech support when needed because they are always very good. 

I would rate Zerto a nine out of ten.
