Easy to migrate data, great recovery speeds, and helpful support
Pros and Cons
  • "The journaling is the most valuable aspect of the solution."
  • "Their data backup and restore have some ways to go."

What is our primary use case?

We had a specific use case for one of our clients that had a regulatory requirement for backups to be further than what we were already able to give with our current backup structure. We are actually a global company and our global headquarters are in Northern Ireland. We're located in Pennsylvania. We're the North American headquarters. We implemented Zerto, and we replicate on our Northern Ireland site. That got us more business with our clients.

How has it helped my organization?

We needed to meet the requirements of the client, and, previous to this solution, we would not have been able to meet the distance. That's why we implemented it.

What is most valuable?

The journaling is the most valuable aspect of the solution. The near synchronous authentication is great. It's critical for our organization.

We haven't had to use Zerto for blocking threats, however, we like that we have it as an option.

We do not do disaster recovery in the cloud or the AWS platform. It can do it. We just don't opt to use it that way.

We've used the solution to protect virtual machines.

It's had a positive effect on our RPOs. Our RPOs are eight seconds. It blows past RPOs out of the water. It's great.

The speed of recovery is excellent. We've only had to test it and never used it in production. That said, it works better than anything we've used previously. 

It's easy to migrate data. 

Its ability to keep users collaborating during a data migration is good. It goes very quickly, so it's not a disruption.

The impact on our RTOs is great. It far exceeds what we've needed it to do.

It will save us time in a data recovery situation.

It's helped us reduce our DR testing. It has gone from hours to minutes under Zerto.

It enables us to make better use of our staff. We have reduced the number of staff involved in overall DR management. 

What needs improvement?

Their data backup and restore have some ways to go. We looked at replacing our traditional backup system with Zerto and found it was lacking about a year ago. We have Commvault, which is very customizable and feature-rich in comparison. Their offering needs to be more robust.

914,109 professionals have used our research since 2012.

For how long have I used the solution?

I have used the solution for close to six years.

What do I think about the stability of the solution?

The stability is great. We haven't had any issues with it. 

What do I think about the scalability of the solution?

The scalability is very good. It can scale out to quite a lot of VMs.

How are customer service and support?

I've contacted technical support once or twice. It was for integration and customization and they've been great.

How was the initial setup?

I was involved in the initial setup, which was very straightforward. It took about a day to set up. Two people were involved in the deployment.

The only maintenance is the annual upgrade. It's pretty much set and forget.

What about the implementation team?

We handled the setup with the help of Zerto.

What was our ROI?

It's hard to quantify the ROI. 

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

The pricing is pretty fair. It's competitive.

Which other solutions did I evaluate?

We did look into VMware. It didn't meet our requirements.

What other advice do I have?

The solution has not replaced any of our legacy backup systems.

It hasn't helped us to reduce downtime, as we haven't had any yet.

I'd rate the solution nine out of ten.

The only issue is that someone would move the VMs involved around. If you have a global team, make sure they understand the strategy and everyone is on the same page so that issues like that don't arise. We had silos on our side and once we dealt with that, we were fine.

Which deployment model are you using for this solution?

On-premises

Easy to use with great granularity and helpful support
Pros and Cons
  • "I like the granularity of the checkpoints."
  • "When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens."

What is our primary use case?

We use the product solely for disaster recovery.

How has it helped my organization?

The solution has helped with zero data loss from a transactional perspective. We have about forty servers in there today and they all serve a core function for our business. With Zerto, it's a matter of just being able to achieve zero data loss in minutes in terms of recovery time. That's amazing, and it really enables our business from a disaster recovery perspective.

The key benefit for us, and why we transitioned to Zerto years ago was really the recovery time. We went from hours to days on some of these applications, to minutes.

What is most valuable?

I like the granularity of the checkpoints. That's been extremely beneficial for us in testing. The near synchronous replication of Zerto is great. Knowing that it's within seconds or minutes allows us to achieve our goals from an RPO perspective. 

I like the live failovers. 

It's also a very easy-to-use product and very easy to administer from just a time perspective. 

We're able to stand up our DR site within an hour if we need to. 

We've been able to use it to do kind VM migrations from site to site in the past. Just it doing it behind the scenes allowed us to dramatically reduce any downtime for private cloud to a private cloud or even on-premise to private cloud migrations.

When handling migrations, it's fairly intuitive. There's a progress bar with percentages. Sometimes the timing fluctuates based on bandwidth. However, it's going completely in the background. It doesn't interfere with anything. When you are live, you can cut over with minimal downtime.

It's improved our RTOs. It's dramatically improved RTOs compared to what we had before.

We've had multiple unplanned failovers and the solution worked as expected. It's probably saved us 24 hours per instance.

The product has reduced the amount of staff involved in data recovery situations. Before the solution, we had two or three different mechanisms for different types of systems in different applications. Now it's just one click, one interface, and one administrator. 

What needs improvement?

When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens. Quite regularly, anytime we do a failover or a fallback, we have to confirm all the settings for each VM. That takes a little bit of time. There is some power shell for that, so we've been able to automate that or at least optimize that. That said, that's my only complaint. Maybe that's a VMware limitation. I'm not sure.

For how long have I used the solution?

We've been a customer of Zerto for several years. We started using it around 2017 or 2018.

What do I think about the stability of the solution?

The stability is good. Of course, from a maintenance perspective, sometimes with the failover, we have to re-sync or set up the settings again for whatever reason. I'm not sure if that is a limitation of the product or a limitation of VMware. 

What do I think about the scalability of the solution?

We have six or seven users that use the solution, and typically just two or three administrators. 

We've scaled in that we have increased our VM count or VPG count. However, if we had thousands of VMs, I'd question the RTO or RPO capabilities at that point. However, ours is fairly small, under 40 VMs, and it has worked well for us. 

How are customer service and support?

Technical support has been great. In our last DR failover, we needed to put in an urgent ticket and we got a very prompt response on that. Based on my interactions with them, by far they have the best support. 

How would you rate customer service and support?

Positive

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

We did use other solutions before, however, they were not as comprehensive as Zerto. We moved to Zerto so we could get our RTO and RPO down to minutes. Just being able to do everything with one administrator makes it much easier than before since we were doing some things from backups.

From a desk disaster recovery perspective, Zerto has replaced all legacy backups. From an administration and time perspective, we're definitely seeing some savings there. 

How was the initial setup?

The initial deployment was not very straightforward. We were able to deploy in a matter of hours. The foundational aspects of Zerto are pretty easy, however, managing VRAs and getting the replication going can be a bit more work.

For the initial deployment, we only needed a single administrator. 

The solution definitely requires maintenance, just to keep everything up to date. However, it's very intuitive and everything happens very quickly, based on how many VRAs you have. We have three administrators capable of managing Zerto as needed. 

We have three sites, either on private cloud or on-premises. They are all VMware-based. 

What about the implementation team?

Initially, a consultant assisted us with the base installation.

What was our ROI?

We have not calculated the ROI of the solution.

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

I was a little disappointed this year with the pricing, especially being a legacy customer of Zerto. 

They changed the licensing structure as a result of the HP acquisition. We had a significant increase that was not very well communicated to us and wasn't planned for us and it hit us pretty hard. From a budgeting standpoint, we only got notified a couple of months before, however, we were already in our calendar year. We couldn't plan for it properly due to the timing. It was frustrating for us. The costs were up significantly for us this year. That is definitely something we will be mindful of and keep an eye on going forward. We may need to find an alternative if the costs keep increasing.

Which other solutions did I evaluate?

We did explore other solutions, such as VMware and other competitors. However, the ease of use and ease of implementation were good selling points and became a key deciding factor for us. 

What other advice do I have?

We have not used the immutable data copies as of yet.

In terms of dealing with threats or attacks, I've read a lot of the white papers, however, we haven't really had to have a need or a use case for that at this point. We're aware of that functionality, however, we haven't had a need to really utilize that, thankfully.

It took us a while to realize the benefits of the product. The initial phase for us was to cover about twenty different servers, which had interdependencies within the application. It was quite difficult. It took us about a year and a half to fully utilize our application or our initial phase of productivity. That said, that wasn't a Zerto limitation. That was the fact that we were changing IP addresses between our sites, so it was more of an application configuration delay. Zerto was ready to go on day one, basically.

We don't use Zerto to support disaster recovery on AWS. We're strictly on-premises hypervisors. We use virtual machines.

We haven't used Zerto's data recovery testing functionality. 

I'd advise new users to utilize the failover testing. You really have to make sure the application functions. Within our use case, for example, we have very interdependent applications. Each piece requires lots of communication, lots of databases, lots of other application transactions that are interdependent, and lots of integrations within our application. Utilizing the failover testing was critical for us.

I'd rate the solution eight out of ten.

Which deployment model are you using for this solution?

On-premises

Constantly replicates and it is economical and easy to implement
Pros and Cons
  • "The replication feature where it constantly replicates and sees that data is always in sync is valuable."
  • "There should be an automatic installation in a cluster. When I add a virtual client or ESX source to the cluster, it should automatically install that. There should be automatic installation. Currently, I have to do that manually."

What is our primary use case?

I am the global lead for infrastructure for the VMware and Windows Server environments. We are mainly using Zerto for disaster recovery. We have a prime site in Missouri, and we have plants in Taiwan, Malaysia, Japan, Italy, and Korea. We have 400 to 500 users in the environment. 

We have installed Zerto software on the DR site and the production site. We will be using Zerto for the production site for all the centrally used applications, such as SAP, file servers, and Exchange. Because this is a central site, a lot of other sites come to this site for various things. 

We also have Zerto on the DR site. In manufacturing, there are 60 or 70 tools, and each tool costs around $500,000. When the site goes down, you cannot transfer these tools very easily. It takes time. These are big tools, and it takes time for them to go somewhere else. You have to do a test again and go through the qualifications procedure, which takes time. As the IT department, we are interested in getting the applications that are used by all the sites centrally located, and if anything happens to the primary site, we want all the applications to be already there on the disaster recovery site. We just bring them up, and we are good to go.

Zerto will help to protect VMs in our environment. We have tried that in the test environment. That would be another reason for using Zerto.

How has it helped my organization?

We have used it for VMs. We know that it is a very good product. So far, we have only synced SAP and tested a few things. For SAP, there were two guys doing that, and they like Zerto very well. They have the test databases up there. It was smooth, and they liked it. The part that we still need to test is the Windows VMs where we can spin up a domain controller, change the IP, etc.

We can move data that is needed to keep our users collaborating with one another using Zerto because we are doing a continuous sync of the site. Once it is synced, we do not have to worry because everything happens in the background.

What is most valuable?

The replication feature where it constantly replicates and sees that data is always in sync is valuable. 

The ease of moving all the VMs is valuable. All we have to do is change the IP address and the VMs are all up and running there. There is a passive sync with all the VMs. That is what we like about Zerto. VMware has its own tool, but you need to do a lot of scripting. In manufacturing, we have a one-man team, so we do not have time for all the specialized work. We needed an application that is more GUI-based so that we can pinpoint and easily move VMs. We can bring up all the VMs and make sure the data is in sync, and we are up and running, so the ease of implementation is what attracted us to Zerto.

Zerto is very easy to use. It is very professional. We had no issues at all. Even for bringing up a new ESX host, they have a standard procedure. It is very easy. With a few clicks, you can do the ESX installation. 

What needs improvement?

There should be an automatic installation in a cluster. When I add a virtual client or ESX source to the cluster, it should automatically install that. There should be automatic installation. Currently, I have to do that manually.

They can give us a few training classes.

For how long have I used the solution?

We installed Zerto just three months back. We have not yet started using it properly.  

What do I think about the stability of the solution?

Zerto is a very stable product. We have no issues. So far, it is working as planned. It is very stable. We will soon be working on it full-fledged. 

What do I think about the scalability of the solution?

It is very scalable. We buy new licenses, and we just add another ESX or VM. We manually install it, and then we are good to go. It is pretty easy.

How are customer service and support?

We have not contacted support yet. So far, so good. Everything is working as planned.

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

I tried VMware replication, but it was too hectic with all the scripts, so I gave it up. 

How was the initial setup?

We implemented it recently. There was the ease of implementation. It was easy and straightforward. 

In manufacturing, we have to make sure that everything is on-prem. The data has to be on-prem because all the tools write immediately to the servers. There are two types of manufacturing. For the type of manufacturing where your tools are constantly writing, cloud applications are not good. For example, when we scan wafers, there is a set of data, and when we go through another tool, there is another set of data. This has to be instantaneous. There is nothing called a cache or buffer on those tools. It has to be instantaneous. We cannot say that the cloud is down, and we lost the data. We cannot stop the tool because this is a manufacturing facility with 24-hour operations on 365 days. We cannot have any downtime where the full site has gone down because this site is used for central applications.

What about the implementation team?

I am the one who implemented it. Overall, there were just two people involved from our side. There was me and one more person. Because it was a new product, we also had a representative from Zerto as a standby. He would just watch our screen while we were implementing it. When we got stuck somewhere, he would help us. Because this was a DR site and it was a little far off, we wanted to make sure that everything went smoothly.

In terms of maintenance, so far, it did not require any maintenance from our side.

What was our ROI?

Having a solution like this is similar to having insurance. When you have a car accident, that is when you know the value of your insurance. Similarly, you cannot put a definite value on a solution like this till something happens, but there is peace of mind in knowing that the software is there, the VMs are there, and we can test it anytime. That is the true value.

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

It is economical as compared to other brands. 

Which other solutions did I evaluate?

We are an HPE shop. Zerto was procured by HPE, and we were looking for a DR solution. We went for Zerto because of its simplicity and ease of installation. We did an on-site proof of concept of Zerto for a year. We liked it and purchased it.

The only other product that we looked at was the VMware one because of the orchestrator. We did not look at any other products. I know that Veeam also has the same features that Zerto has. We had some discussions, but we never looked into it. Once we had a product that was easy to install, we did not feel the need to compare. It was doing what we wanted it to do.

Another factor for going for Zerto was that its price was economical. My boss, who is the CTO, liked its licensing scheme. It was much more economical as compared to VMware, and that is why we went ahead with Zerto.

What other advice do I have?

Before implementing this solution, in terms of preparation for disaster recovery, you have to identify the business applications that are critical to your environment. You have to scope that out and make sure you have your VMs accounted for because licensing depends on the number of VMs. With a product like Zerto, you have to know the number of VMs and the size of data you are going to sync. These are the two factors that you have to look into for disaster recovery. 

Zerto is way better than other products. Installation is done with the click of a button. Everything happens in the background. You do not have to worry about it. As a product, we have not had any issues so far. However, we have not yet done a full-fledged disaster recovery. We have done minor testing, and we want to do major testing. As of now, I am very happy with the product. It does not need any further modifications. It is simple. It is nice. It is easy to execute, so I would keep it that way.

We have not yet used Zerto for immutable data copies. I have been playing around to migrate a VM and see how it works. So far, we have only used it to sync up the SAP side. Our SAP stuff is already synced up, and we have done some testing of it, but we have not done any disaster recovery.  

I have not had a chance to assess Zerto for blocking unknown threats and attacks. We are mainly interested in using it for disaster recovery.

Overall, I would rate Zerto a ten out of ten.

Is easy to install, upgrade, and manage
Pros and Cons
  • "The low RPO times of about four to eight seconds are very nice and very valuable to us."
  • "What I appreciate the most about Zerto is that it is the easiest to install, upgrade, and manage."
  • "The alerting could be fine tuned and improved. It does a lot of alerts, but it's a little bit cumbersome to modify them."

What is our primary use case?

We use it primarily for DR.

What is most valuable?

What I appreciate the most about Zerto is that it is the easiest to install, upgrade, and manage. Most things in the product are fairly intuitive and easy, including upgrades. You don't have to dig through a bunch of manuals or go through a bunch of technical data to make it work.

The low RPO times of about four to eight seconds are very nice and very valuable to us.

What needs improvement?

The alerting could be fine-tuned and improved. It does a lot of alerts, but it's a little bit cumbersome to modify them.

It could be cheaper as well.

For how long have I used the solution?

I've been using it for six years.

What do I think about the stability of the solution?

The stability is very good. We haven't had any real problems or downtime. The only thing is that it runs on Windows, so that has its own problems.

What do I think about the scalability of the solution?

Zerto's scalability is very good. We haven't had any scaling problems. We tested out DR in Azure, DR to VMware on GCP, and DR on AWS. It performed on all of those. The AWS setup was the most complicated, but AWS with Windows is a little bit messy.

We currently have 400 licenses. We have two ML350s, and we use Zerto to keep them replicated. If one fails, we just move to the other. That has been expanding, and that's where we've been adding licenses.

How are customer service and support?

Zerto's technical support is very responsive. We had some posts that were not working properly and caused some issues with Zerto. The technical support staff were very helpful and worked through the night to help us resolve that. They always solved any problem I've had, so I'll give them a nine out of ten.

How would you rate customer service and support?

Positive

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

We used SRM. It had a lot of specialized plugins and specialized machines, but was very cumbersome. We weren't guaranteed that it would work all the time. It was very complicated to set up and manage as well.

SRM was storage-vendor-dependent because you had to have plugins through the storage vendors. It wasn't IP-based at the time and relied on storage-based replication. We had disparate storage arrays and disparate systems, and the IP-based replication treasury was much more resilient on our end.

How was the initial setup?

The initial setup was unbelievably easy. We had Zerto up and running in five minutes, whereas setting up the SRM replication took weeks and needed technical support staff.

What about the implementation team?

We deployed it ourselves.

What was our ROI?

In terms of ROI, it was quite expensive, but I think we got a lot of value out of it, such as being able to have a reliable DR method, particularly offsite. We have very poor latency locations, and sometimes, we replicate those. Zerto makes that very easy.

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

From a customer perspective, the price is okay. From an investor's perspective, however, it is a little bit high.

Which other solutions did I evaluate?

We looked at Veeam, but Zerto was a better match for our needs.

What other advice do I have?

I would advise you to give Zerto a try in your environment. Get a trial license and see how it works. I think you'll be very impressed.

Overall, I've been very happy with Zerto, and I'd give it a rating of nine on a scale from one to ten.

Is very cost effective, easy to use, and straightforward to set up
Pros and Cons
  • "The replication for DR is really good, and the test failover within the application is really solid, along with the ability to manipulate RDMs or remove them."
  • "Zerto can completely replicate a server so that when an issue arises we can be up and running with no downtime, and if we're doing a planned DR exercise, it can be set up in advance so that there's zero downtime."
  • "The only thing I really don't like about Zerto is that the ZVM has to be a Windows server. I can spin up any OBA template whenever I want to, but if it has an OS that's tied to it, then I have to involve the OS team from my company. That drives me crazy."
  • "The only thing I really don't like about Zerto is that the ZVM has to be a Windows server."

What is our primary use case?

We offer Zerto to our application owners and system owners as a DR solution for them. It's part of our service offering from the VMware side because we do the infrastructure for them. We help orchestrate and set it up for them at the back end.

We also use Zerto to remove RDMs from the environment and help manage our storage. If we need to relocate the storage, we use Zerto, especially when going from multiple vCenters or multiple clusters. It's very convenient.

How has it helped my organization?

We can completely replicate a server so that when an issue arises we can be up and running with no downtime. Also, if we're doing a planned DR exercise, it works really well. It can be set up in advance so that there's zero downtime.

Using Zerto to get off of old storage has been more convenient than using VMotion.

What is most valuable?

The replication for DR is really good, and the test failover within the application is really solid, along with the ability to manipulate RDMs or remove them.

We are required to do DR testing for almost every application every two years. Zerto made it more convenient and significantly faster for us. Our job is a nice little 15 to 20 minute stint that anybody can do within our organization. I don't need a full-on engineer. I can have an operations person handle it.

Zerto has really great online training, and they gamified their training pretty well too.

When you compare Zerto's ease of use with that of SRM and Veritas, Zerto is really easy, especially when you're doing a DR exercise or a failover. It has evolved and is now even easier. With every iteration, they make the verbiage clearer, and people just gravitate to it. I can have someone from the operations team help with DR when Singapore's doing a DR exercise, for example. This helps a lot as a company with a global presence. The other solutions require a little bit more understanding of the technology. They are not as forgiving if you make a mistake.

The speed of recovery with Zerto is faster than that with SRM. Much more engineering management needs to go on after the fact with SRM.

Without Zerto, in the event of downtime, it could take hours to get back up and running. Some VMs could take eight to ten hours just to get to a point where they could accept a restore from a backup solution, if that solution is even available.

Zerto does a really good job with their packeting on the networking side, and I've never had a site experience an impact because Zerto was running a replication.

What needs improvement?

The only thing I really don't like about Zerto is that the ZVM has to be a Windows server. I can spin up any OBA template whenever I want to, but if it has an OS that's tied to it, then I have to involve the OS team from my company. That drives me crazy.

For how long have I used the solution?

I've been using this solution for five years.

What do I think about the stability of the solution?

It's exceptionally reliable. I'd give it a ten out of ten. Any complication we've had has usually resulted from the Windows team patching that server or some other behavior.

What do I think about the scalability of the solution?

Zerto scales really well. It scales out really wide, and you can tie it all into your primary site. You don't need central management.

We have around 900 hosts across the world globally. We have a little over 10,000 VMs and have mixed usage with lots of databases, applications, and web-based applications. We have about 27 primary vCenters and seven manufacturing vCenters.

How are customer service and support?

Zerto's technical support takes really good advantage of the community. When you put in a service ticket, they redirect you to a message blog or message group. Then, you can use that to also vet what other people are saying, and you can use that as a great resource.

On a scale from one to ten, I would rate technical support at ten.

How would you rate customer service and support?

Positive

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

We used SRM before we switched to Zerto, and Zerto is very cost-effective.

How was the initial setup?

Zerto is very straightforward to set up. The only drawback is having to have the Window server.

After the Windows server is deployed, it takes less than an hour to deploy the solution.

What was our ROI?

Zerto does exactly what it says it's going to do. I don't have to go back and babysit it. If something happens, it alerts me. I don't have to sit there and add hours of babysitting or monitoring. I can be doing other tasks. That is our ROI.

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

Zerto is very cost-effective. We get really great value for the cost of the service.

Which other solutions did I evaluate?

We looked at Veritas.

What other advice do I have?

I'd give Zerto a good look. Put it through its paces. Look at how you're already offering a DR exercise and how complicated it is in your life. If you're looking at a run book for a DR exercise and your part is two or three paragraphs, Zerto can make it one paragraph.

I would strongly recommend Zerto to make it a little easier and would rate it a ten on a scale from one to ten.

Which deployment model are you using for this solution?

On-premises

  • "I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors."
  • "It's a nice tool, and you should go for it; I don't think you'll be disappointed."
  • "One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere."
  • "One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades."

What is our primary use case?

We primarily use it for disaster recovery.

What is most valuable?

I like the less than one-minute RPO, the ability to IP customize during failovers, and the cloning feature that I can use to clone VMs over at the target location. As part of the automation failover, if we need to change an IP when it fails over to the other data center, Zerto will handle that; there's no need for manual intervention. As far as the cloning, we use that to do quick testing of a VM in the remote data center for lift-and-shift processors.

In terms of ease of use, Zerto is better than SRM now because you can do automated VM protection. As long as you set it up, enable it, put the tags on the VMs, and have the template VPG created, it works. With SRM, we use array-based replication, so anytime a VM goes on a replicated data store and that replicated data store is in a protection group in SRM, it's automatically protected. So there's no intervention needed to protect that VM. Initially, the fact that I had to manually create the VPGs when a new VM came in was a con for me with Zerto when I was comparing it to SRM, but now, I'm happy with Zerto's automated VM protection. We currently use both Zerto and SRM in tandem.

If I had to manually create the VPGs, it could take thousands of minutes.

As far as the speed of recovery, Zerto is faster than SRM because, with SRM, we use array-based replication. This means that we have to shut down the machine, detach the data store, and attach it to the other side. All of this takes time. In Zerto, that doesn't happen because it's continuous, VM-level replication. So, the data is going right over to the other target data store. When we run the recovery on Zerto, we recover a VM in under 10 minutes, so the RTO is less than 10 minutes, as opposed to some SRM plans that can run an hour or two hours.

What needs improvement?

One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere.

For how long have I used the solution?

I've been using Zerto since 2018.

What do I think about the stability of the solution?

Zerto is pretty solid in terms of stability.

What do I think about the scalability of the solution?

I'm sure it scales well. In our legacy environment, we only used a 100-pack license, so we only used 60 machines on that license. That was a fairly small footprint. In this new environment, we estimate at least a couple of thousand because we're shifting from SRM to Zerto. I expect it to scale well.

How are customer service and support?

Zerto's technical support is better than that of most vendors that I deal with. I can open up a support ticket and have someone get back to me within a couple of hours. Even with a Severity 3 ticket, someone will email me within a couple of hours. I will rate them a nine out of ten.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup process is simple. You get the executable, you stand up a VM, you install it on a VM and open up firewalls, and connect the ZVM to the ZVRA data sites. It's fairly straightforward.

You can deploy Zerto in under two hours, as long as the firewall is in place. When the firewall is in place, everything runs smoothly. Otherwise, it takes a while.

What about the implementation team?

I deployed it myself.

What was our ROI?

I do think that we've seen a return on investment. We started off with SRM in our legacy environment, and it was probably protecting 90% of the estate. Now, we have a new environment, and Zerto is now protecting 90% of the estate, and SRM is only doing 10% or even less than that.

What other advice do I have?

It's a nice tool, and you should go for it. I don't think you'll be disappointed. On a scale from one to ten, I would rate Zerto at ten.

Makes it easier to do failovers, is stable, and is straightforward to set up
Pros and Cons
  • "I like that the failover is simple and that it's a stable platform. It makes it easy for us to do failovers in the event that we have an issue. It also makes it easier to do test failovers because we can test it prior to actually doing a real failover. This means that we can pull things back or commit them over on the other side. Zerto streamlines the process instead of having to have a whole team of people who are dedicated to disaster recovery."
  • "It's just a better solution all around."
  • "We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement."

What is our primary use case?

Our use case is disaster recovery or failover. It makes it a lot easier for us to actually test DR because of some of the coordination and orchestration that are a part of Zerto. However, our use case is strictly DR, making sure that we have the right RPOs, and Zerto does a good job of handling that.

How has it helped my organization?

Zerto improved a lot of the processes that we do for disaster recovery. It makes it a lot easier when we talk to our upper management and letting them know that we have a way of getting data from one data center over to another data center without a whole lot of friction.

What is most valuable?

I like that the failover is simple and that it's a stable platform. It makes it easy for us to do failovers in the event that we have an issue. It also makes it easier to do tests of failovers prior to actually doing a real failover. This means that we can pull things back or commit them over on the other side. Zerto streamlines the process instead of having to have a whole team of people who are dedicated to disaster recovery.

When you compare the ease of use of Zerto versus that of SRM, it's a night-and-day difference. SRM was very kludgy to set up when we implemented it. Zerto was a lot more streamlined from that perspective. SRM wasn't very stable for us, sometimes it would work, and sometimes it wouldn't. With Zerto, we rarely have any issues that can't be fixed with a phone call. It doesn't require a full rebuild, and the upgrades are simpler. It's just a better solution all around.

We don't have a whole lot of downtime, to begin with. When we've had issues, Zerto has allowed us to move the workloads quicker. I would say from a configuration perspective, Zerto saved us quite a bit of time over SRM. Zerto is a set-it-and-forget-it type of tool. We get into it only when we need to.

When you compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions its fairly quick. We can failover a workload from our headquarters to our DR facility and have it up and running in 10 or 15 minutes, which is pretty good. A five-minute migration is also a nice feature.

Zerto hasn't reduced the staff involved in a data recovery situation because we're a fairly thin IT assistance team. However, with Zerto, we don't have to plan ahead for additional resources just for an eventual or potential failover.

When we do regular disaster recoveries, where we do a full failover and test in our DR facility for a couple of days, Zerto makes it a lot easier to move it from one place to another and make the VM agnostic to the datacenter.

What needs improvement?

We're an NSX-T shop, and if I could get an NSX-T integration where it could manage the networks a little tighter, that would be an improvement.

The other improvement is working with storage vendors, like Pure Storage for the synchronization of the data similar to what SRM does. Using Zerto for the orchestration, and the hardware vendor for the replication would be beneficial.

For how long have I used the solution?

I have been using Zerto for about three years.

What do I think about the stability of the solution?

The stability is very good. It's rare that we have a complete outage. Sometimes, we have a VPG that doesn't replicate correctly, but a call to tech support gets it resolved.

What do I think about the scalability of the solution?

Right now, we have about 120 VMs that are being replicated, and we have an eight-second RPO. I consider that good performance for our workloads. I know we could scale out easily using our current configuration.

How are customer service and support?

Zerto's technical support is very strong. When we have an issue, it gets resolved quickly. We have never had an issue with Zerto's support.

We've had good experiences with all of the engineers that we've worked with, so on a scale from one to ten, I would rate them at nine.

How would you rate customer service and support?

Positive

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

We used SRM previously, and it wasn't very good. We ended up having to rebuild it a few times.

How was the initial setup?

The initial setup was fairly straightforward. Everything made sense, and after a couple of days, we were up and running.

What about the implementation team?

We had an engineer from Zerto help us with the implementation.

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

I think the cost is reasonable for VM licensing. It's not outside the scope of an enterprise product.

What other advice do I have?

On a scale from one to ten, I would rate Zerto at nine.

Which deployment model are you using for this solution?

Does not rely on a secondary backend product and is easier and more straightforward to use
Pros and Cons
  • "I found VM level replication and being able to group the VM levels to be valuable. I like not having to worry about whether a particular VM is in the right storage group; some of those sorts of things would trip us up previously."
  • "Overall, Zerto is a very good product for us."
  • "There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more."
  • "There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for."

What is our primary use case?

We primarily use it for DR, that is, for VM replication between two data centers, using it not only for replication but also for orchestration.

How has it helped my organization?

Zerto provided better overall DR coverage and more consistency.

What is most valuable?

I found VM level replication and being able to group the VM levels to be valuable. I like not having to worry about whether a particular VM is in the right storage group; some of those sorts of things would trip us up previously. 

It's a lot easier and more straightforward for a VM administrator because he can know that this VM goes in this group or gets this tag, for example, and that it's now in a DR group and is taken care of. I don't have to worry about all the backend details. It's just simplified.

In terms of ease of use, the benefit of Zerto over SRM is the fact that it doesn't rely on a secondary backend product, with having to have the right storage groups with RecoverPoint or something else with multi-tier architecture.

It's still too early to compare the speed of recovery with Zerto versus the speed of recovery with other disaster recovery solutions. We've just started the DR tests to understand the time difference. However, from what I've seen so far, the speed of recovery is similar but more consistent with Zerto. We don't have situations where we've missed this or that.

Zerto reduced the staff involved in data recovery situations by a single person. Now, we don't have the backend storage person who has to keep an eye on it anymore. With a different solution, we would have needed two people.

What needs improvement?

There's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more.

For how long have I used the solution?

I've been working with Zerto for about two years.

What do I think about the stability of the solution?

The stability seems fine. I haven't seen any issues with it thus far.

What do I think about the scalability of the solution?

For our organization, the scalability matched our needs. Between the data centers, we probably have somewhere in the neighborhood of 3,000 VMs.

How are customer service and support?

From what I have seen, the technical support has been very good. They've been very responsive to my team.

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

We previously used SRM. Zerto is a little bit more mature, has a better feature set, and is more aligned with the features and functionalities that we need.

What was our ROI?

We have seen an ROI from the perspective of a reduction in hardware and a reduction in the number of people trying to focus on the tool sets.

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

It is less expensive than the full solution that we had previously, but at the same time, it's not an inexpensive product either.

Which other solutions did I evaluate?

We evaluated Cohesity and other solutions.

What other advice do I have?

Overall, Zerto is a very good product for us, and I would rate it at nine on a scale from one to ten.

Storage software that offers consistent performance in the conversion of Hyper-V to VMware
Pros and Cons
  • "Zerto offered us massive time saving and consistency, and we have a consistent outcome every time we complete conversions."
  • "We wanted to shut down the dev environment to focus on the prod environment. We couldn't find any option in Zerto to do that."

What is our primary use case?

We have approximately 1500 to 2000 Hyper-V machines. Those Hyper-V machines are being used and converted to VMware. We use Zerto for our conversion from Hyper-V to VMware. We are also considering using it for DR purposes. 

Our prod environment runs on-premises and we have a DR copy of everything that we run in production. Our development runs on machines and hardware. In the event of a DR event, we would shut down dev and bring up our secondary copy of production. We hope that Zerto is going to be the tool to help us do that.

How has it helped my organization?

Zerto offered us massive time saving and consistency. We have a consistent outcome every time we complete conversions. We move from one platform to another with different loads being moved each time and Zerto's results are consistent each time.

We convert 30 to 50 VMs from Hyper-V to VMware on a nightly basis which has resulted in saving time as this is good throughput. Zerto also helped to reduce downtime. If we were to do this manually, we would have a lot of downtime to shut down those VMs on Hyper-V to be able to do the conversions.

What is most valuable?

The ease of the conversion moving from Hyper-V over to VMware is the primary reason why we chose Zerto and is its most valuable feature.

What needs improvement?

There has been one pain point that we have run into. We wanted to shut down the dev environment to focus on the prod environment. We couldn't find any option in Zerto to do that.

For how long have I used the solution?

We have been using this solution since the start of 2022. 

What do I think about the stability of the solution?

This is a stable solution that offers consistent results. 

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

From a DR perspective, we use a few solutions. We have multi-site data centers in our environment along with Cohesity. We use Cohesity from a backup and DR perspective.

What other advice do I have?

If you're in the middle of conversion between different platforms, regardless of if you're moving from on-premises to host it or from one environment to another, Zerto is agile and able to move your workloads into different environments pretty easily.

I would rate this solution a nine out of ten. 

Which deployment model are you using for this solution?

On-premises

Is user friendly, has great recovery speed, and has good technical support
Pros and Cons
  • "I found the very easy VPG setup, the easy recovery, and failover testing to be the most valuable features."
  • "Zerto made our migration from different data centers very easy and very smooth."
  • "Even though Zerto is for disaster recovery, it would be nice if it can also make backups."
  • "I would give technical support a nine out of ten. I'm taking away a point because, at times, they send emails for me to read when I need something done immediately."

What is our primary use case?

The primary use case is to migrate VMs. It's easier to use than HCX and SRM.

How has it helped my organization?

Zerto made our migration from different data centers very easy and very smooth. Zerto support and our account manager have always been there to help us out.

What is most valuable?

I found the very easy VPG setup, the easy recovery, and failover testing to be the most valuable features.

It's very user-friendly. You only need a couple of clicks, and it gets the job done. We also have SRM, but Zerto just requires a couple of clicks. You can test with Zerto, and you don't have to commit. So in terms of ease of use, Zerto is better. That's why we use it for migration.

In terms of reducing downtime, we don't actually have any because of seeding and mirroring. However, on the failover, it only takes two seconds of a blip.

Zerto's speed of recovery compared to that of others is great. It's incomparable, and the ease of use is always there.

What needs improvement?

Even though Zerto is for disaster recovery, it would be nice if it can also make backups.

For how long have I used the solution?

I've been working with Zerto for three to four years.

What do I think about the stability of the solution?

It's very stable. They have bug fixes. If there's a problem, you can report it, and they immediately provide a solution.

What do I think about the scalability of the solution?

Zerto's scalability is amazing. If they could do backups in the future, it would be better.

We're in a healthcare environment, so we have probably 30,000 VMs. We only have a couple of licenses, but that's probably going to grow in the near future. We're going to be using it in the cloud as well.

How are customer service and support?

I would give technical support a nine out of ten. I'm taking away a point because, at times, they send emails for me to read when I need something done immediately.

How would you rate customer service and support?

Positive

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

We previously used SRM. We use Zerto because it is just easy to use. You don't need to set up a lot of stuff. You only need to set up one appliance on each site, and you're good to go.

How was the initial setup?

The initial deployment is very straightforward. You just install the appliance, make sure that all the ports are working fine, test the connection, and you're done. If you have any problems, technical support is always there to help.

What about the implementation team?

We had help from CDI for the initial deployment, and they were not bad. It was easy enough, but we had to use our credits. If it were not for the credits, we could have done it ourselves.

After the initial deployment, my team has been doing all the upgrades and any other setups.

What was our ROI?

We're down to a couple of data centers now, and our data center cost is going down. That is the ROI we have seen with Zerto.

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

The pricing is fair.

Which other solutions did I evaluate?

We evaluated SRM.

What other advice do I have?

You don't have to evaluate Zerto; it just works. I would give it a ten out of ten;
I have no complaints.

Which deployment model are you using for this solution?

On-premises
