User-friendly, cost-effective, and saves a lot of time
Pros and Cons
  • "It is very user-friendly. There is no wondering about what a feature does. It is easy to use."
  • "If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration."

What is our primary use case?

We use Zerto for server migrations between data centers during the role swap that we do. We use it from a recovery standpoint as well.

We currently do not have disaster recovery to the cloud. We go between our data centers. That is what Zerto helps us accomplish.

How has it helped my organization?

Zerto works very well. We have not had any faults while using it. We are a financial institution, so we have to make sure the systems we have are available with very minimal downtime.

It has helped out a lot in man-hours. It has saved us a lot of overnight work. We can literally change our production servers in a matter of minutes to hours. Rather than having to do this gradually or a couple of weeks in advance and have several teams and business partners involved, we can literally do it live on the same day.

Zerto is probably one of the faster ones in terms of recovery. You can just go into the console, and because it is always replicating over to the other side, it takes minutes.

What is most valuable?

Being able to do our recovery and being able to migrate between data centers during the role swap is valuable just because of the amount of time it takes. It takes 55 hours or so. Right now, we are doing this in a VDI environment. We are going to experiment with it as a proof of concept because we have a thousand machines that we have to move and do all the assignments. Zerto would lessen that down by a few hours, and then we can use some scripts to do everything on the Horizon's side. We have not done it yet, but we are hoping to reduce it down to about 3 hours instead of 55 hours. We will also be able to manage our host better and be in a better recovery state. If the host happens to go down, we can quickly recover.

It is very user-friendly. There is no wondering about what a feature does. It is easy to use.

What needs improvement?

If they already do not have it, they can have some APIs for the Horizon environment. Instead of having to use some scripts to get around, they can make it a lot more user-friendly for integration.

Learn what your peers think about Zerto. Get advice and tips from experienced pros sharing their opinions. Updated: June 2024.
793,052 professionals have used our research since 2012.

For how long have I used the solution?

We have been using Zerto for two years.

What do I think about the stability of the solution?

It has been very stable. We have not had any issues while using it. When we need it to do its job, it is always dependable.

What do I think about the scalability of the solution?

It scales very quickly. We can set up a whole new environment in an hour. We can get the server setup and all the VMs that are required for it to function in an hour or two.

How are customer service and support?

I have not used their support. My peers had to use it. They seem very responsive and knowledgeable. 

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

The other DR tool that I have used is from Symantec. It was an old-school recovery tool. It was back in the day when it took a whole day to get things back up.

How was the initial setup?

It was deployed before I joined the company.

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

Its price is fair. It is very cost-effective compared to the cost of the labor for your workers and associates. 

Which other solutions did I evaluate?

We selected Zerto over others primarily for the ability to replicate and help with our role swap. It cuts the downtime of the production systems by a large volume. This way, we can meet the deadline and not have that much client impact. In the financial side of banking, you do not want bad performance.

What other advice do I have?

I would rate Zerto a nine out of ten. There is always room for improvement, but it definitely makes your life a lot easier.

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?

The solution can achieve very low recovery point objectives due to its efficient use of resources and compression techniques
Pros and Cons
  • "I give Zerto's stability a nine out of ten."
  • "Zerto's price has room for improvement."

What is our primary use case?

Zerto is primarily used for disaster recovery. In rare cases, it is also used for backup, but only for long-term storage.

We deployed our on-premises infrastructure in two data centers in Russia located in two cities, and multiple regions with combined infrastructure. We also had two data centers in Europe.

How has it helped my organization?

Zerto is extremely easy to use. When I started to pilot the product in 2016, I was able to deploy all required components in one or two hours without any help from Zerto engineers. I only used the provided documentation and user interface. In the years since my engineers have also had no issues with the implementation or configuration of the product. Zerto's ease of use is one of its best features.

To ensure good synchronization and replication of changes in a timely manner, we need to have a very good storage subsystem. In our case, we replaced our old storage subsystem with a new one that is based on full flash storage. After that, Zerto started to replicate changes at lightning speed. Many companies experience issues with Zerto if they do not have full flash storage. When full flash storage is implemented, Zerto is the best replication solution because it is highly dependent on the latency of the storage. Therefore, any kind of storage that is not based on full flashes, such as hybrid storage that combines flash and disks, is not a good foundation for Zerto implementation.

Prior to implementing Zerto, our disaster recovery tests had a 70 percent success rate. After implementing Zerto, all DR tests were 100 percent successful. This represents a significant improvement in our DR capabilities.

We used Zerto to replicate our virtual machines from our primary data center to our disaster recovery data center in another city over a single connection.

Zerto can achieve very low recovery point objectives due to its efficient use of resources and compression techniques. However, our company has different RPO requirements for different-sized companies. Since our company is small, our standard RPO is four hours. Zerto exceeded this requirement by achieving a typical RPO of about 15 seconds.

Zerto is a very easy and fast tool to use. However, it is important to note that Zerto requires some time to accept changes after migration. This means that if we do not finish testing within the required time frame, we may run into issues with storage space, as Zerto will continue to collect logs and other data. If the testing period is short and we are comfortable switching between data centers frequently, then we should have a very good experience with Zerto. Compared to VMware SRM, Zerto is much more reliable. I have never had any issues switching between production and the DR data center with Zerto, while I have had to start DR exercises from scratch multiple times with VMware SRM.

We always define and perform the required RTO values in our company. RTO is the time required to recover from a switch. It is about how long it will take IT staff to restore the environment. With Zerto, we can now do this in hours, typically one or two hours, for all switching activities. We have 70 virtual machines configured in Zerto, so it takes about one hour to switch all of them. This is four times faster than our previous solutions, such as VMware SRM or storage-based replication.

Zerto has saved us time in data recovery situations due to ransomware or other causes. It is very easy to use, so we do not need to spend extra time training engineers on how to use it. All of our engineers were able to start using Zerto immediately. Zerto is also very fast at replicating data. For example, when we set up a new replication, the initial replication was completed very quickly. Another advantage of Zerto is that it does not require additional steps to change the size of virtual disks. With our previous solution, VMware SRM, engineers had to perform additional manipulations in VMware when changing the size of virtual disks. This was a complicated process, but it is not necessary with Zerto. Overall, Zerto is a very user-friendly and efficient data protection solution. It has saved us time and money, and it has made our data recovery process much easier.

Zerto has saved us around 50 percent of our time.

What is most valuable?

The most important thing to me is Zerto's ability to deliver continuous protection for all data without any issues or incidents. Zerto is a rock-solid product in terms of protection. We migrated to Zerto from VMware SRM because we had a lot of issues with VMware SRM, including the loss of one server.

What needs improvement?

Zerto's price has room for improvement.

For how long have I used the solution?

I have used Zerto for six years. 

What do I think about the stability of the solution?

I give Zerto's stability a nine out of ten.

What do I think about the scalability of the solution?

Globally we have around 200 engineers that use Zerto.

How are customer service and support?

Zerto's technical support is excellent. When we first started using Zerto, we had Russian technical support to help us with some complex tasks, such as configuring unique virtual machines. Our engineers had no communication issues with the support team. Later, when we were in a stable period, global technical support was also very helpful. I cannot recall a time when technical support was unable to help us. Overall, I give Zerto's technical support five stars.

How would you rate customer service and support?

Positive

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

For many years, the company globally used a variety of different solutions for data protection and disaster recovery. These included storage-based replication solutions based on IBM and EMC storage, as well as special appliances from Dell EMC. For smaller companies, VMware SRM or VMware replication without SRM was used, with manual configuration of replication. In order to simplify and unify its data protection and disaster recovery strategy, the company decided to adopt Zerto. Zerto was initially implemented in a small region, the Middle East/Asia. After a couple of successful migrations of data centers in this region and a parallel unsuccessful DR exercise in EMEA, the company selected to use Zerto globally. Following this, smaller companies in Russia started to receive a recommendation to implement Zerto instead of any existing solutions. Zerto has been a success for the company, providing a unified and simplified data protection and disaster recovery solution that has improved the company's overall resilience.

How was the initial setup?

We used one internal engineer to perform the initial setup on two data centers in two days. In general, this involved installing two virtual machines with Zerto Virtual Manager on each data center, creating the corresponding network access rules, and then deploying Zerto replication agents to all virtualization hosts. The last activity was automated, so it took about one hour to deploy Zerto for all virtualization hosts. The replication took one week.

What about the implementation team?

The implementation was completed in-house.

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

Zerto is a premium disaster recovery solution. It is not the cheapest option on the market, but it offers a number of features that make it a good value for businesses that need a comprehensive disaster recovery plan.

What other advice do I have?

I give Zerto a ten out of ten. Based on my experience with different replication solutions, Zerto is the best one I have used. I am very disappointed that my current company decided to stop using it due to existing standards. Zerto is not cheap, but it is very stable, available, fast, and easy to use.

The most time-consuming part of a disaster recovery test is the testing of small and medium-sized enterprises, business users, and other stakeholders. IT-led environment restoration activities typically take up about 30 percent of the overall DR process. Zerto can reduce this time by 50 percent. Overall, this is not a significant impact, and Zerto is a very stable and reliable solution.

Zerto has not reduced the number of employees involved in data recovery situations. This is because we have a small team, and we always use engineers to perform disaster recovery activities related to storage and virtualization infrastructure. As a result, we have not had to reduce the number of staff members used for these activities.

Zerto did not replace all of our legacy backup solutions. Our legacy backup solutions were dependent on IBM Power servers, which required corresponding backup agents. Zerto is not compatible with these agents, so we use a separate backup solution for these servers. This separate solution is still in use.

We have two data centers, each with its own equipment, servers, storage, network equipment, and so on. In each data center, we deployed two separate VMware vCenter server infrastructures connected using an L2 line. There was no L3 connection between the data centers. This created a flat L2 network with two data centers and two vCenters on each data center. After that, we deployed two VM servers configured for replication. This allowed us to have a highly available and resilient infrastructure in the event of a failure at one of the data centers.

Regarding Zerto's maintenance, we configured some monitoring for related Zerto services. However, we do not have any daily routine procedures to manually check Zerto to ensure that everything is working properly. Instead, our engineers spend one hour per week reviewing monitoring items and other metrics to ensure that Zerto is operating as expected. From my perspective, Zerto is a self-operating system that requires very little manual intervention.

Zerto is very easy to pilot. I recommend that any customer pilot Zerto before making a decision on whether or not it is the right solution for them. Zerto is a self-selling product. When I piloted it in 2016, I was able to install it in hours and start using it immediately without any help. I believe that a pilot is the best way to see how easy and beneficial Zerto can be.

Which deployment model are you using for this solution?

We have seen significant reduction in RPOs and are now able to position our DR in the cloud
Pros and Cons
  • "The near-synchronous replication is one of the primary reasons we're using Zerto because we have recovery intervals of sub-five seconds. On a scale of 10, where 10 is "very important", this feature is a 10."
  • "Zerto's connectivity with automation platforms could be improved. For example, vCenter can use a VMware-developed tool called Site Recovery Manager. That can be integrated with automation platforms such as Terraform, Ansible, Chef, or Puppet, to perform automated, self-sufficient recoveries to essentially avoid any downtime. To my knowledge, Zerto does not have integration with those platforms."

What is our primary use case?

Our biggest use case is real-time replication to a secondary site in case of the need for a disaster failover. We also use it for file-level protection and restore, but the main purpose is to help add another layer of protection in the event of a disaster.

How has it helped my organization?

The biggest improvement we have seen is that Zerto has taken our anticipated recovery time from between hours and days down to seconds or a minute. Zerto has also helped us to protect VMs, and the effect on our RPOs has been incredible. Pre-Zerto, it was days if not weeks. Now it's six seconds. I don't even know if you could compare it to the RPO of our old solution. It's 100x. If we were to recover using our old system, we would lose between a day and a week's worth of data. With this, we lose virtually none.

And in terms of our RTO, recovering and validating the system has gone from between hours and days, to now happening in a matter of 30 minutes to a few hours. It has helped reduce downtime by days. Similarly, our DR testing has gone from being a multi-day process to a multi-hour process, and we use almost all of that time we save for bolstering value in other projects.

As for the number of staff involved in our backup and DR management operations, Zerto has helped us decrease it.

It has also allowed us to locate our DR in the cloud. We currently use Azure, and this ability is incredibly important as it has enabled us to reposition our resources in an environment that is separate from our main environment.

What is most valuable?

The most valuable features for us are the analytics and reporting. Being able to see a snapshot of our environment, and knowing where we stand in our recovery atmosphere using Zerto, are really valuable aspects.

The near-synchronous replication is one of the primary reasons we're using Zerto because we have recovery intervals of sub-five seconds. On a scale of 10, where 10 is "very important", this feature is a 10.

We also use Zerto for immutable data copies. We have two recovery locations and both of them are immutable, both for short-term and long-term recovery. Using this component has essentially enabled implementation of the 3-2-1 rule for us. Zerto has been pivotal in that process. Before that, the process hadn't changed in about a decade and a half. This enabled us to take a leap into the 21st century in that facet.

What needs improvement?

Zerto's connectivity with automation platforms could be improved. For example, vCenter can use a VMware-developed tool called Site Recovery Manager. That can be integrated with automation platforms such as Terraform, Ansible, Chef, or Puppet, to perform automated, self-sufficient recoveries to essentially avoid any downtime. To my knowledge, Zerto does not have integration with those platforms. Zerto does have an API, but a lot of those automation platforms have prebuilt runbooks to enable that process, whereas Zerto does not.

For how long have I used the solution?

I have been using Zerto for about five years.

What do I think about the stability of the solution?

It's incredibly stable, to the point that we don't have to second-guess whether it is functioning properly.

What do I think about the scalability of the solution?

Its scalability is infinite. We have yet to run into an issue of resource allocation or scalability.

How are customer service and support?

Their support is very good. Debatably, it's the best support we have seen out of all of our vendors.

How would you rate customer service and support?

Positive

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

One of our previous solutions was VMware Site Recovery Manager. We switched because we have some servers that have a lot of transactions and we weren't able to afford to lose even an hour's worth of data. Zerto takes that potential data loss down to seconds.

And Zerto is much easier to use.

How was the initial setup?

Our deployment is both on-prem and, for replication, in Azure. The initial setup was straightforward. There was a learning curve in transitioning from our old environment, but it didn't take very long to learn.

It took us about a month to fully deploy.

Outside of updates, it doesn't require any maintenance.

What about the implementation team?

We did it in-house with support from Zerto when needed. On our side there were two or three people involved, but it was primarily done by me.

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

It's expensive, for sure, but for us, it comes down to the fact that we do not replicate our entire environment using Zerto. We replicate the mission-critical servers and services, so the yearly cost of Zerto is heavily outweighed by the potential cost of an outage. It's expensive but worth it.

Which other solutions did I evaluate?

We very briefly looked at solutions such as Veeam and the option of continuing to use VMware SRM. The biggest difference was the de-snapshotting of the environment into journals with extremely low RPOs, versus scheduling a snap at a certain time.

What other advice do I have?

Overall, Zerto is pricey and it fulfills a very specific need, but it is incredibly worth the investment if uptime and recoverability are priorities.

Reasonable price, great support, and helpful for keeping our website up and running without interruption
Pros and Cons
  • "The recovery was pretty seamless. It took about a minute for it to kick over when we did our testing. So, it wasn't a long downtime."
  • "When it comes to a solution, one of the things the management wants is to standardize platforms. That's why when Rubrik came out with their solution, they wanted to look at it. For instance, if you have multiple technologies, you're going to need admins to manage all those different ones. I would like Zerto to be something that fits all our needs, including the backup that Rubrik provides, but I understand that not all solutions can be that way."

What is our primary use case?

It is mainly for disaster recovery of our public-facing website.

I oversee the infrastructure team. I'm the lead for the infrastructure. It is not one of the technologies that I've primarily managed. As an infrastructure lead, I have my hands on every project, and it is hard for me to just focus on one. Especially because it is more of a disaster-recovery type solution for us, as long as replication is going fine and there are no issues, we don't really go in and play with it much.

How has it helped my organization?

It does what it claims to do. I can't say whether it improves anything. It is just the fact that we want to make sure our public-facing website is up 24/7, and Zerto gives us the capability of doing that.

It hasn't reduced downtime because we haven't experienced any downtime yet. We've done annual testing to make sure that it is working properly. So far, so good.

What is most valuable?

The replication is valuable. We have two data centers, and it is replicating from our main data center to another data center. In the event that there is an issue with the first one, it just goes over, and we have the website up and running. It does an automatic build. It keeps our website up and running without interruption. It is constantly replicating. It has the most up-to-date information, at least until the main one goes down, and then it automatically brings up the other one. It is already pre-configured with the network and everything else. So, the website is up and running in seconds.

The recovery was pretty seamless. It took about a minute for it to kick over when we did our testing. So, it wasn't a long downtime.

What needs improvement?

Zerto is more of a set-and-forget-it type of solution. As long as the replication is continuous and there are no issues, I don't touch Zerto. We don't have a lot of workload that needs to be up. We just have our web server and our applications here. Those are two main servers that we get up and running in a disaster-recovery type situation. I can't give any area of improvement from a real-world experience because we haven't had that issue, but from testing, Zerto has been working great. 

It is not something that goes beyond what our use case is for. When it comes to a solution, one of the things the management wants is to standardize platforms. That's why when Rubrik came out with their solution, they wanted to look at it. For instance, if you have multiple technologies, you're going to need admins to manage all those different ones. I would like Zerto to be something that fits all our needs, including the backup that Rubrik provides, but I understand that not all solutions can be that way. When I started working here, my predecessor who was managing Zerto had no documentation. So, I had to take over. No one else knew how to manage Zerto. So, there is just that type of learning process. That's why management wants to standardize on one solution so that it is easier to cross-train, but that's not Zerto's part. It just happens to be our environment and our management style. Zerto as a solution has been great for us.

For how long have I used the solution?

I've been using it for about three years.

What do I think about the stability of the solution?

It has been stable for us. We had networking issues that caused the replication to break, but once we had that resolved, replication was seamless again. The
networking issues were on our side.

What do I think about the scalability of the solution?

I don't have much input for its scalability because we only have a maximum of three servers that we need Zerto to bring up and get running as soon as possible, in the event that the main data center goes down.

How are customer service and support?

It has been great. I've only requested support twice. The support engineer that worked with me has been great. I believe it was for the upgrade process, and he reached out to me and informed me that there was a new version that fixed a lot of the bugs from the previous version. He worked with me to get both data centers up to the latest version. I would rate them a 10 out of 10.

How would you rate customer service and support?

Positive

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

I haven't used any other one. Rubrik just happens to be coming out with a similar solution, and because we use Rubrik, management wants us to take a look at it and do a comparison between the two.

How was the initial setup?

Aside from working with the network team to get all the networking pieces configured, it was pretty straightforward. Installing the agents on the servers and doing the initial replication took the longest time because we have close to a terabyte of data that has to be replicated from one data center to another, but other than that, it was pretty seamless.

What was our ROI?

It gives us peace of mind. It hasn't happened yet, but it does happen. Based on our annual testing, we are pretty much happy with what Zerto has done or can do.

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

Zerto is pretty reasonable. I haven't checked to see how much Rubrik is going to quote us for their solution. At least for us, the price doesn't play a big factor in the decision-making because it is a pretty small deployment for our use case.

Which other solutions did I evaluate?

We're currently evaluating Rubrik because we use that as our primary backup solution, and they just came out with a technology that's similar to Zerto. My managers, the executives, and I are in discussion on possibly looking at their solution and comparing it to Zerto to see which is the right fit for us.

In terms of ease of use, I haven't played with the Rubrik one yet just because they just announced it, but Zerto is pretty straightforward. I went in, and I did all the configuration myself within about 30, 40 minutes.

What other advice do I have?

It is a great solution for what it does, but every company and every department has its own use cases. It is just a matter of evaluating different solutions that are available and picking the right one for your environment. For us, Zerto happens to be the right one.

I would rate it a 9 out of 10 just because it fits our needs for the solution and the environment we're in.

We perform more DR testing now because it is so easy
Pros and Cons
  • "The test features have been really good for us. Our DR testing goes very quickly and easily now for all our stuff with Zerto. We have our priority recovery process, where we cover our databases for our app servers and web servers. All our teams pretty much get their VMs very quickly. The RPOs are very low."
  • "I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet."

What is our primary use case?

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

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

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

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

How has it helped my organization?

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

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

What is most valuable?

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

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

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

What needs improvement?

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

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

For how long have I used the solution?

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

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

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

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

How are customer service and support?

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

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

How would you rate customer service and support?

Positive

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

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

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

How was the initial setup?

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

What about the implementation team?

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

What was our ROI?

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

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

Which other solutions did I evaluate?

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

What other advice do I have?

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

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

Which deployment model are you using for this solution?

On-premises

Has significantly reduced our organization's RPO and RTO
Pros and Cons
  • "Zerto has helped reduce our organization's DR testing to seconds to minutes. We have been able to save probably close to 200 hours a year."
  • "If something happens, and we are out and about, I would like to be able to interface with it on our mobile phones. That would be great."

What is our primary use case?

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

How has it helped my organization?

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

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

What is most valuable?

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

What needs improvement?

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

For how long have I used the solution?

I have been using it for about five years.

How are customer service and support?

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

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

How would you rate customer service and support?

Positive

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

It replaced Veeam. Zerto is a lot easier.

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

What was our ROI?

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

What other advice do I have?

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

I would rate Zerto as 11 out of 10.

Provides continuous data protection and decreases the time and the number of people involved
Pros and Cons
  • "It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing."
  • "We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking."

What is our primary use case?

It is for real-time data protection and, if needed, for the ability to recover within seconds at a point in time. It is deployed on-premise and multi-cloud on Azure and AWS.

How has it helped my organization?

It just gives us extra peace of mind. We can backup and recover critical information not only on-premise but also off-premise at multiple places. So, we have that additional place for recovery if Azure or AWS is having problems.

When we need to fail back or move workloads, Zerto decreases the time and the number of people involved. It definitely speeds up the process of recovery for us. We essentially need only one person for the recovery process. In other solutions that we had in the past, we had to involve quite a few of our team members in the recovery process. We haven't had to do fail back a lot, so I can't give a real numeric number of how much it has saved us. If we had to do a big fail back, I can see where it could have saved us.

It has reduced the number of staff involved in a data recovery situation. The number of staff involved is less than what it used to be. We can basically do that with one person. It also reduces the number of staff involved in overall backup and DR management.

It has saved us money by enabling us to do DR in the cloud rather than in a physical data center. We don't have to buy another SAN, so it has saved somewhere in the $150,000 to $200,000 range.

What is most valuable?

The reliability of the solution and ease of upgrades are most valuable. Support has also been really good on it.

It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing.

It is easy to use once you have gone through the online training class to learn the basics about it. We have been able to get a couple of our folks in the IT department up to speed on how it works and how to utilize it within basically a day or less. It is relatively easy for us to get staff trained and get going.

What needs improvement?

We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking.

For how long have I used the solution?

We've been using this solution for three years.

What do I think about the stability of the solution?

It has been very stable for us. We haven't had any issues with it. Even upgrades have been relatively seamless for us. If anything, it is just that you miss something on the upgrade release note and you need to open a port or something else, but there is nothing critical.

What do I think about the scalability of the solution?

It seems to be very scalable. We're not that big, but it seems to scale out for us and give us more scale for what we are size-wise. It could be very beneficial for a bigger organization.

We started out protecting roughly 30 terabytes of data, and that's roughly where we're right now. We have 30 terabytes of data and 250 employees. We are just trying to keep them all functioning 24/7.

At the moment, we don't have any plans to increase the usage. We're utilizing everything we can at the moment. The only thing that we might consider down the road is the backup functionality long-term, but that's something we just keep evaluating versus what we currently have. What we currently have works so well, and we don't really want to change it.

How are customer service and technical support?

Their support has been really good. They've been very proactive in helping resolve issues, and you get quick callbacks or contact with them. I would rate them a 10 out of 10.

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

They used Avamar Data Domain before Zerto. It had a very complicated process, and the price was also very high. It did not have a similar granularity of recovery points.

How was the initial setup?

It was pretty straightforward. We had it fully installed and started implementing it within the first couple of hours of the process. We worked with the local rep for about an hour or two, and by then, we had the process down. After that, it was pretty straightforward, and we just replicated that for additional protection groups.

In terms of the implementation strategy, we knew what we needed. We wanted to get out in the cloud. We focused on Azure to start with and then came back and looked at AWS after the fact for a couple of use cases where Azure wasn't the best place for some big data sets.

For its day-to-day maintenance or administration, there is just me. We do have desktop admins that can get into it as well if they need to be, but generally, I take care of it all for them. They just holler out if they have a problem or a question about something, and I can take care of it for them.

What about the implementation team?

We worked with the local rep for about an hour or two. Our experience with him was very good. He was very helpful and knowledgeable about the product and also about the ways other folks were using the product.

What was our ROI?

There is nothing that we can quantitatively define, but we are able to meet regulatory requirements.

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

It initially seemed a little pricey, but in the big picture, you're paying for peace of mind. It could always be cheaper and more competitive, which would make it an easier choice for people, but I can see both ways. They can say this cost is for the value they are providing. If anything happens, they can recover your data very quickly. You won't be losing it, so there is a win. It is a win-win.

Which other solutions did I evaluate?

We evaluated VMware Site Recovery Manager. I have used that in the past, and it is okay, but upgrades tend to break a lot of stuff, whereas Zerto hasn't had that kind of issue, which is great. It is never a good thing to do a minor update and then your whole system is dead for maybe a day or two until you figure out what caused the breakage. We also looked at SRM and Cohesity. Cohesity was more for just overall backup, not for full DR.

Zerto was very easy to use. We could use it for backup and DR, which was very important for us. That was one of the key driving factors for us.

What other advice do I have?

I would advise others to just get the training before utilizing it so that you have a better understanding of the overall product. You should also have plenty of bandwidth for your providers so that replication works seamlessly.

It has helped us a little bit in reducing downtime in a couple of cases. It saved us a few hours here and there. It could save us time in a data recovery situation due to ransomware or other causes. We haven't had to use it currently for that. Its overall backup and DR management could also reduce the number of people needed.

We don't use Zerto for long-term retention. We have another solution in place for that. We will evaluate Zerto possibly down the road.

I would rate Zerto a 10 out of 10.
