Zerto Reviews

We primarily use the solution for DR purposes. 

It provided an easier way to set up everything regarding DR. We had a small team. There were only four people and one of them was a manager, so we had just three people with one desktop guy. We were looking for a solution that was easy to set up, did not require too much maintenance, and something we didn't have to constantly keep an eye on. Zerto provided that. 

The setup is easy and very comfortable. There are not too many issues doing the upgrades. Maintenance is easy and configuration is easy as well. It's all just GUI-based. You just select the server that you want on the DR and it starts the application. 

Transfers between the data center are good as well. They do the compressions and also the encryption. That way, you are protected and it doesn't consume too much bandwidth.

The interface is very good. It's not too complicated. The interface is way easier than Veeam. You can do everything from the interface - including authorization of DR. 

Its near-synchronous replication is good. We get an RTO of five seconds. They also provide different checkpoints. They maintain a lot of checkpoints, so you can go back in time on the DR side if you want to. Of course, there is a limitation based on how much space you have. 

We noted the benefits of Zerto immediately. Before I joined, the company used to do a very manual process. We started doing a POC with Zerto, Veeam, and Pure Storage. I found that Zerto was easier to manage - and it's cheaper than the rest of them. That, coupled with the limitation of the human resources, we wanted to have less maintenance, less interface, and I found Zerto very, very useful in that process. 

Zerto covers our entire production environment. If something goes wrong, you can use Zerto to recover the server if you want. Mainly, we started Zerto just for protection.

The recovery time objective is good. We've had no issues. If the line goes down, it recovers very quickly since it provides a lot of compression in the data. It doesn't consume much bandwidth.

If we have issues in our database, we can recover the data. We can go back and time and pull out whatever is lost. 

Zerto has helped us reduce overall DR testing in our company. What used to take a month I can do in less than two days. 

It's impacted our IT resiliency strategy. It provides, in terms of DR and data protection, peace of mind. We can get our data back quickly.

They have moved to appliances, and the configuration of appliances is a bit complicated. The appliance is is very complicated to configure by proxy as they move everything to containers, and each container needs to be configured. It's a little bit complicated.

I've used the solution for almost eight years. 

The stability of the solution is very good. I'd rate stability nine out of ten. 

It's easy to scale Zerto. I'd rate scalability nine out of ten. 

I've contacted technical support. I've had no issues with them. They are well-versed and know the answers. 

Positive

I did not previously use a different solution. 

The initial deployment is easy. We create a server and deploy. You just answer a few questions, and you are done. 

Even if a person is new to Zerto, it would still be very easy. As a very small team, we are always searching for products that aren't too complicated. 

The deployment itself might take half a day. It's a one-person job. 

If you add new servers, there will be maintenance. You can also set up reporting if you like. 

When we first deployed eight years ago, we may have used somebody from Zerto. They provided us with help as they were new at the time. If I had to do it again, I could handle it on my own. It's not too complicated. 

The pricing is reasonable and very affordable. 

We did look at the Veeam. We also look at the Pure Storage. Pure Storage also had some sort of replication, however, the RTO was too big. The RTO was around 15 minutes with Pure, and Zerto was providing an RTO of five seconds.

We are end-users. 

I'd rate the solution nine out of ten. 

When using this with VMware, I'd say it is very easy to set up. I haven't used it with Hyper-V, however, I've heard that Zerto may not develop a version for Hyper-V. 

I use Zerto for ransomware resilience and data recovery.

Zerto has improved my organization by allowing us to replicate individual VMs or groups of VMs. It allows flexible protection and recovery of data. It is also easy to integrate with other solutions.

It has had a positive effect on our recovery time. It is very fast.

Zerto is easy to use. As long as you have the technical know-how, it is easy to use.

The near-synchronous replication is good. It ensures data availability and fast data recovery. I love that. We use Zerto to replicate the VMs from one site to another, ensuring data availability, protection, and disaster recovery.

Zerto has had a good effect on our RPOs. There is continuous protection and availability of data because it is all automated.

It is very fast. It has had an effect on our RTOs. It has reduced our downtime by 20%.

Zerto offers a comprehensive solution for data recovery and protection. It has saved us a lot. It has saved about 30% of the time.

Zerto has a user-friendly interface and intelligent dashboard. It is easy to manage. It has saved about 40% of the time.

We have had a positive impact on our IT resiliency strategy. Continued data protection and automated DR have been very helpful.

Zerto has simplified our compliance with industry regulations.

I love the seamless data integration between on-premises and cloud environments. Fast disaster recovery is also valuable.

I also love that it provides real-time and historical analytics.

It simplified my work. It has a user-friendly interface. It is easy for me to create my views in the dashboard. It makes work easy for me.

I am enjoying it so far, and I am happy with its capabilities, but it is expensive.

Their support can be faster.

I have been using Zerto for three years.

It is stable. I have been using Zerto for three years, and my company had been using it before I joined. It is stable. I would rate it a nine out of ten for stability.

Its scalability is good. Zerto can meet the needs of any business.

We use it in multiple departments and at multiple sites. There are ten people who use Zerto. They are strictly admins.

My experience has been positive. They are always trying to help.

I would rate their support an eight out of ten because we sometimes do not get a fast response.

Positive

I have used the Microsoft Azure solution, but I could not get the fastness, scalability, and ease of management that I wanted. I was looking for these capabilities, and that is why I went for Zerto.

Zerto is a better solution, but it is expensive. Zerto is a bit faster than other solutions. Other ones have automated disaster recovery, but Zerto is faster.

It is deployed on the cloud. Its deployment was straightforward. It took about three hours. Three people were involved in its deployment.

Like every other software, it does require some maintenance from time to time, but it is not much.

We have seen an ROI. Whatever we do, we are getting a fast result. It is always an advantage for the business. Zerto has had a positive effect. I do not have the metrics, but it has saved us a substantial amount.

It is expensive.

I would recommend Zerto to anyone who wants fast disaster recovery and protection. It has most of the features that people are looking for. 

I would rate Zerto a nine out of ten.

The solution was primarily used for disaster recovery for clients. If there was a major issue in the data center, it allowed the client to move to the second data center. It was also used for migration to virtual machines.

My customer recently (a few years ago), had a major issue in one of the data centers. It was a virus attack that destroyed the servers and virtual machines. We could not recover those servers or virtual machines. After that, we decided to remove the corrupted data center and get everything recovered using Zerto. We were able to do that with the agreed-upon RTO and RPO for the customer. 

The replication between data centers is great. It allowed us to ensure all data was replicated from one side to another.

The near-synchronous replication is great to have. It works better than other solutions. 

It's very user-friendly and straightforward. There are no bugs in the software.

The disaster recovery features are the best I've found. 

This product allows us to do disaster recovery in the cloud rather than the physical data centers. We have multiple customers who are on a hybrid cloud. Some are on a private cloud and some are on a public cloud and Zerto allows us to provide the functionality whereby we can cover both as well as across physical data centers. We use Zerto for AWS, Azure, and GCP.

It was nice to use with AWS. Everything was in place on AWS and the functionality is well documented. We've done a POC on it. We have not yet had a chance to do a real disaster recovery just yet.

Zerto has helped us protect VMs in the customer environment. The overall effect on the RPOs is good. We can do it at a maximum within 15 minutes, however, often we can do it within five minutes, or even one minute. 

The speed of recovery is very quick compared to other tools.

It's easy to migrate data with Zerto. It's simple. Even non-technical users can see what information is needed in order to enable the replication from one site to another.

Users can still collaborate during the migration process in Azure. It depends on how much data you are including from your data center. The bandwidth connectivity between two data centers is very high.

The RTO is pretty good. We typically give our customers a heads up it will be eight hours, however, it's often less.

It's helped us reduce downtime. For example, when I was using another solution, we wanted to restore a VM. It took more than eight hours to restore ten virtual machines. In contrast, Zerto only takes 45 minutes. 

We had a corruption at one point on 20 to 25 VMs, that were critical from the customer's point of view. They had already spent so much time trying to troubleshoot. We decided to use Zerto to restore the machines and give them the latest backup. We were able to give them everything in less than one minute.

For the customer to recover using a different solution, it would take much longer. Zerto takes far less time. For example, compared to VMware SRM, it takes almost double the time compared to Zerto. 

We've been able to reduce DR testing. When we used to give RPO and RTO time to our customers, two hours for RPO and eight hours for RTO, once we started using Zerto, we reduced RPO to 15 minutes.

It's reduced the staff time involved in a data recovery situation. When we initially set up Zerto, it immediately starts replicating and does incremental replication as well. Therefore, at any given point in time, the latest data is already available on the recovery side. We just have to trigger it and everything will be restored as per our configuration. We likely save three to four hours of work during the disaster recovery period. And, in the disaster recovery phase, every minute is crucial. 

It's also reduced staff involvement. It's not complex and very straightforward. Since tasks are reduced, we do not need so much staff. 

Previously, it was not compatible with the public clouds. However, now that it is, it's helped a lot. One of the most challenging aspects in migrating items from private to public.

We'd like to be able to migrate data without its operating system or any other functionality and without having to go through a virtual machine or server. 

I've used the solution since 2015. I stopped using it around 2022.

The solution is absolutely stable. We have customers that have used it since 2016 without any concerns. 

The product can scale. 

We haven't had to engage with technical support. 

I'm familiar with VMware SRM.

Not a lot of people in the market are aware of Zerto. They need to market it better.

However, Zerto is pretty simple and straightforward, compared to other options on the market.

Replacing the legacy solution has helped customers remove compatibility issues and reduce costs. 

The deployment of the product is straightforward. We have, for example, more than 100 VMware ESX-site servers and there are two agents in terms of virtual machines that get deployed on all of them.

To deploy the solution, it only takes 30 minutes. You only need one or two resources to manage the implementation. The maintenance is minimal. Once it's set up, it's fine. 

Our customers have witnessed an ROI. 

The product is cost-competitive and less than other options. I do not have too much data on the exact costs, however. However, we are definitely saving costs when we compare Zerto to VMware. 

My understanding is we have a partnership with Zerto. It provided free training to our employees and we have done multiple certifications. 

We did not use it for immutable data copies.

We don't use it for blocking unknown threats and attacks. We don't use it for security purposes. We have other security protection services for our customers, including firewalls and antivirus. We use Zerto only for disaster recovery.

I'd advise potential users to pay attention during the initial setup and watch what you are replicating from one side to another. After the setup, you will not have to put a lot of time in - as long as you pay attention during the initial phase. 

I'd rate the solution nine out of ten.

Our primary use cases are for disaster recovery replication side to side. 

We were running VMware Site Recovery Manager and it ran well. It was a great solution compared to what we had before. We didn't have disaster recovery issues. We were just doing our test. It ran superbly. Zerto improved the amount of time it took to failover and address any issues. We went from failing over in about three or four hours during the test to it taking one hour. It was very fast.

It's in a single department in a single company. Luckily, we don't really have to support much of our field force. We have approximately 4,000 agents who are in eleven states, but we don't have to go out into the states. We're on in one building and it's one business unit. We manage the failovers but it's just one group management.

Approximately four users use the solution.

One of the most valuable features is the ease of management. It's very easy to manage. My team grew and a team member took over my role for Zerto support. He was able to pick the ball up and run with it. It was very easy for him to pick it up and go forward. I haven't had to do a lot of management of the product. 

Our RTO is between four to ten seconds to our site, which is about a hundred and fifty miles north of my location. We bought dedicated lines and we've been very happy with Zerto's performance. 

Zerto's two main features are ease of management and that the product just works. It does what they say it'll do.

The near-synchronous replication Zerto offers is exceptional. Our pipe is 10 GB and we haven't overloaded that connection. We are very satisfied with it.

During our test last year, we moved systems around for users to test with. We had some misconfigurations in the journal sizes, they just weren't big enough. There was logging left on some SQL servers. Our DR test lasted for three days. We had a dedicated group come in and test. We failed back to production and then put it in the test phase again. We did it all within thirty minutes, and it worked very quickly. We were very satisfied.

Zerto has had a major impact on our RTOs. We've been feeling the impact for a while. It's steady here. It's exceptional. SRM dwarfed as far as our targets for RTOs. 

Zerto has reduced our DR testing. It reduced the amount of time we have to test because it's so easy to failover. We've been very pleased with that. It's even given us the option of where we might be able to test more often anytime. We would like to get to a place where we test it once a month where we would allow some business units to test, and then do another business unit the next month.

It used to take us a week for the failover process and testing. The testing has been majorly reduced to where it now takes a day. It took a day to failover, to get everything lined up and running, and it never worked. We never were able to officially have a successful DR test. SRM fixed that and then Zerto took it to the next level. It improved drastically. This has freed up staff to work on other tasks. It used to be that we needed a room full of people for the test where we now need two. 

I don't feel like we're a big enough customer to warrant being called every week or every month but it would be good to get a little bit more contact with a salesperson or engineer group. Our account executive is very good. He's done a great job, but it was hard for him to tie down an engineer. It was a little bit of a strain to get somebody lined up to show us what version 10 was about. Once we got it, it was perfect. It would be nice if it could be easier to do that. 

They have VPGs and VRAs. The management of that when trying to do a VMware upgrade can get a little finicky. You have to bring nodes or hosts up and down where the VRAs are running on the hosts. Sometimes the VRAs won't come back up or they may not respond. So when you're done doing your work, it could be that you have fifteen servers that are not replicating. So you'll have to stop, delete, manually remove what you need to do, recreate the VRA, and that's easy enough but you have to go through and do that, and then resync. That's part of IT. They are a little finicky. 

Version 9.7 has been a little easier to work with, and it integrates with VMware a lot easier. It shuts down the VRAs. The VRAs are finicky about how they get shut down. 

I have been using Zerto for six years.

We've been very satisfied with the stability of it. 

It is scalable. 

Support has been pretty good and responsive. I would rate them a nine out of ten. They're good. 

Sometimes getting in touch with somebody is hard. We're not that big of a customer though. 

Positive

It's been easy for new users to pick up and it was pretty easy for multiple people to work within the UI.

I was indirectly involved with the setup. It didn't take very long, it was like doing an upgrade. 

You just build the servers and the proxy up, install the VRA, and then one by one had them sync.

Seven months ago we had to do a complete resync which took about four to five days. It was straightforward. There is a lot of documentation on Zerto's support site. My advice would be to get the documentation off their site. Open a ticket for support at the same time. 

We have seen ROI in terms of resources and time. For our overall management of the system, it doesn't require too many resources. The upgrades are not too bad. You may have to dedicate a staff member to do it for a couple of days. I didn't have a lot of experience with it and the two upgrades I did were simple.

In terms of time, it has saved us north of 30%. It cut down on a lot of manpower. There has been a reduction in our management pattern from other prior solutions.

You pay to play and it's not cheap but it's worth it. 

We know we have the capabilities to do disaster recovery in the Cloud rather than in a physical data center. We're replicating about 150 miles north of us. That's probably going to happen in the next five to ten years for us. We're making a pivot to where we know we're going to have to go that way with some of the cloud solutions.

We have not had to use it for data recovery due to ransomware. We have gone through the industrial hardening of our environment. We have been rated as very mature as far as our security stands. We have actually had some counterparts that experienced some issues and they didn't have anything in place, and it was very bad for them. Luckily, we have not had to use it in that capacity. We feel really good about its capability from the testing we've done. We know we can use it for malicious attack response.

We have tested it to help protect VMs in our environment and we have found that it will work for that. We got decent results with testing and I was very impressed.

In terms of it reducing our overall backup and disaster recovery management, it hasn't. We needed two staff members for the last two solutions we used. This year we will need three because I will also be involved with Zerto.

Zerto has replaced our DR and replication legacy solution. We're using Veeam for our backups but Zerto has replaced everything replication-wise. It saved costs to manage them by 20%.

My advice would be to do a POC for its concept and everything you get. Get it. Do it. It's a good product. I have friends that work with other companies that provide similar services and one of their engineers told me that you can't beat Zerto. 

I would rate them an eight out of ten. 

We use it for migrations and VM protection.

The near-synchronous replication is very good. It's very critical for us. For example, with SQL, we used to use Always On to protect databases at the database level, to give us high availability and DR. But now, in Azure, we don't do that. If we wanted to do that, we would have to have a SQL Server on the protected site and another up and running on the DR site and those machines would always have to be up and running. To save on costs, instead of using Always On, we're now protecting the VM as a whole, thanks to Zerto.

It's also the main tool that we use for our annual DR tests for all of our production applications. Once a year, for one week only, we do a failover of those critical production applications from the primary site to the DR site and we let them run there for that week. Zerto does the failover and the DR site becomes the active site while everything replicates to the former primary site. Once the week is over, we do a failback and Zerto is the main tool that we use for that, and we repeat the whole process. We're then good for the whole year. Zerto is protecting those VMs.

Another advantage is that Zerto has decreased downtime for us. It could have been a situation where we were down for weeks because of something that Azure did on their end. Even though Zerto has a partnership with Microsoft Azure, sometimes Azure makes changes that are disruptive. There was one change that affected our ability to replicate our critical workloads and it was a rough one. For that week, Zerto found a workaround because they were not getting any progress on resolving the situation from the Azure team. Zerto applied the workaround in their code and we were good, but that was a rough situation. Zerto goes out of its way to help its customers. We've had issues but Zerto has been very responsive.

The quickness and efficiency of creating snapshots, on a real-time basis, is one of the most valuable features. Whenever changes are made on a server, Zerto starts taking snapshots right away and replicating them to the DR site. It's very effective and very quick. Our SLAs are 24 hours, but Zerto could do what we needed, on-prem, in seconds, and in the cloud, in minutes. Zerto is way ahead of what our SLAs are.

Sometimes we do failover tests to make sure that we will potentially have a successful failover or migration. It's very flexible and does its job very well. And one of the things I love about the product is that whenever you do a failover, it gives you the ability to either commit or roll back. Some of Zerto's competitors don't have that ability, at least in Azure. That's critical for us because after we have DR tests on a weekend, we have users sign off on their applications that everything is fine. If something isn't right, we can always roll back to how everything was right before we started the DR test. And if everything is working great, then we commit.

Since we are primarily in the cloud now, Zerto definitely needs to update its platform. When we were decommissioning one of our on-prem data centers and going to Azure, there were issues. And with Azure, it's still limited in the way we can manage our resources there. Zerto hasn't quite kept up to date with how certain elements run within Azure.

In Azure, there is something called resource groups. You cannot create a resource without a resource group. You can apply tags to resource groups and that tagging information is very critical to our company because we now have 95 percent of our production environment workloads running in the cloud. We have to make sure that every resource group is tagged correctly, with the correct team and department because we have to bill them at the end of the month. The problem is that Zerto does not have that ability. When the product fails over or migrates a VM from on-prem, or even within Azure, to another site, it does not give you the option of selecting an existing resource group.

When it fails over, it uses the name of the group that you created within Zerto. The VM is failed over with no problem in a reasonable amount of time. But the problem then becomes that the resources are part of a resource group that has no tags. It does not follow our naming commission for resource groups and then we're stuck. It's not as easy just renaming the resource groups.

These components are very critical for us but they are missing in Zerto. They're aware of it because we've had feature-request meetings with our Zerto account team. They're working on it for the next release and have mentioned that they are going to be making improvements to the product. But for now, it's lacking.

Also, a downside with Zerto is that there is a lot of management overhead when running it in the cloud. On-prem, we used to have one Zerto management appliance, but in the cloud, we have about 20 to manage to protect our VMs. Zerto has mentioned to me that, for the next release, they're building it from the ground up and it will be much better in the cloud, with more cloud focus.

Because of the experience that I had with Zerto running on-prem, where we only had one appliance in each of our data centers, I deployed one in Azure as well. Little did I know that there were limitations and that more appliances had to be deployed because of all the replication of the traffic and the number of VMs that we were trying to replicate. But Zerto stepped in and helped when it came to that.

I have been using Zerto for four years.

The stability is an eight out of 10.

The scalability is also an eight out of 10.

They're very helpful. They always want to understand your situation and, even if they're not sure, they do their best to help and fix the problem. 

For on-prem, there were always references, but for the cloud there is a bit of a knowledge gap. I would always get workarounds, fixes, or KB articles for on-prem, but the cloud implementation is where the documentation is lacking. But the team does its best. It depends on who you get. Some know Azure, or cloud, and some still lack that knowledge. But if they don't know, they get the right person on the call.

Positive

We were a VMware shop on-prem and we were migrating to the cloud from on-prem VMware to Azure, so the tool that we were using to protect VMs through DR would no longer work. We used VMware SRM (Site Recovery Manager) for years when we used to be solely on-prem. 

We started looking for a product to help and, at the time, Zerto was the one that stood out among the competitors, and it was a solid product, so we started using it. Zerto is definitely a more effective product. It is a lot quicker when bringing our VMs up on the DR side, and even when we do a fallback. And Zerto is a lot easier to use than VMware.

The initial setup was not straightforward.

And maintenance is required for upgrades when there are newer releases, especially when it comes to Azure. There are newer releases that contain fixes and improvements and we do update the version of the Zerto appliance. They are running on Windows Servers, so we also have to patch the operating system. In Azure, there are a lot of SKUs with different pricing. Depending on the utilization of a VM, we sometimes make changes to the family types to save on costs at the VM level.

I did it with our Zerto account team, which included our sales engineer. Just the two of us were involved.

Zerto saves us a lot of time. One team member alone can handle the DR test using Zerto, whereas before, when we used SRM, at least two or three people were involved from the VM perspective and from storage. VMware was integrated with our NetApp environment and that meant at least two or three team members were involved. But with Zerto, just one person uses the product for a DR test.

We looked at Azure Site Recovery. We were close to going with it. It did have the ability to do resource group selection, but there were two showstoppers at the time that prevented us from going forward with it.

When we were looking at Azure Site Recovery, it seemed that it had a better cost per VM, but Zerto was not that far off. And we were more comfortable using Zerto to protect our VMs than the other products we were testing.

My advice is that if you're in the cloud, you really should test the failover of your VMs. If tagging is not a key component, you'll be fine. But if it is, that is a huge problem. And expect a lot more management overhead when it comes to managing Zerto in the cloud.

In terms of our RPOs, Zerto is consistent. From time to time, it may run past our SLAs, but that's because there are network or VM issues. And that happens very rarely. It almost always meets our RPOs.

The ease of moving data varies on the size. A good thing about Zerto is that it does give you a little chart indicating the step that it's at in the replication process.  But even if it's a small VM, it does take some time, including setting it all up and starting the synchronization. It's not instant.

We do a semiannual disaster recovery test, usually one in January and another in September, where we fail our entire company over to our Arizona DR facility. We run the business out of the Arizona location for the day. In order to be able to do that, the Zerto application allows us to migrate 58 machines over to that location and allows us to run our business from that location for the course of the day.

We are able to have a successful disaster recovery solution through using Zerto for our Disaster Recovery drills. We are able to fail over anytime, day or night, to run our applications out of our Arizona facility. Within a 15 or 20 minute time frame, we can have those application servers up and running in Arizona. It is just a huge help to have a successful, reliable disaster recovery solution that we know at any point in time, within 15 or 20 minutes, can be running out of a different location.

Most of the time, this is at least a two person job. Previously, when we had a disaster recovery drill it would take two of us working for three or four hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I'm able to finish my work in about 30 mins and be available onsite to help and assist anybody else as needed during the disaster recovery drill. Its ease of use and the ability to have a reliable solution for disaster recovery has become invaluable to us.

There is built-in active logging if needed for a longer retention period. If we fail a machine over and are just doing tests for it, we can fail it right back at the end of the failover without much issue. We couldn't do that with SRM. The ability to keep track within the activity log of what is going on with the VM, then fail it back prior to the one-hour time frame that we have set up without having to worry about it losing data during our tests or production failover drills.

The product is very easy to use. On a scale of one to 10, I'd say it's a nine as far as ease of use goes. In order to do an update in our old product (SRM), we basically had to take down almost our entire vCenter to be able to do the updates. Whereas, I can do updates to our Zerto product within 30 minutes to both our ZVMs in Massachusetts and Arizona. We haven't had problems troubleshooting after doing upgrades. Within five minutes, we can configure a whole new cluster solution and work on getting it synced out to Arizona.

It transfers up-to-the-minute files. Therefore, if something was to happen and the business was to go down Massachusetts due to a server failure, we could simply fire up those VMs in Arizona within approximately five minutes. The data protection level is top-notch. We haven't lost any machines, data, or VMs during the course of utilizing this product.

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue.

Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available.

It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution.

Almost two years.

The stability is rock-solid. Nothing has gone down since we installed it; there has been no downtime.

Typically, once a quarter, we have an update. Last year we were at version 7.5, then we recently went updates to 8.0. On top of that, they release security patches and other things to improve bugs they find in the program. Right now, there is a U4 version that's out, which we will be updating to this quarter.

In the U4 version, there are security enhancements because a lot of zero-day issues that are being found in a lot of the applications. Zerto is making more security modifications and enhancements to the encryption between one location and another, so somebody can't hack your data and access it while it's in transition.

Scalability is very easy. We are going through a POC right now because we want to branch out to the cloud. Just getting that set up and going through the process was about 60 minutes.

It's very scalable and extendable. We can do one to many solutions, as far as where our disaster recovery is going. This is what we wanted. We would never have been able to do that with our SRM product.

There are two engineers trained to use the product. I'm the primary contact for the application and do most of the work on the product. One of the storage guys handles a lot of the storage set up on the back-end with me. We have at least two people trained on each application that we have in-house. Both of us are in charge of making sure the application is up-to-date and doing what it's supposed to be doing. 

Zerto's technical support is very good. They are very reliable and always very pleasant to deal with. We've never an issue working with them. They usually come back with the precise solution to whatever we are troubleshooting.

Our issues are usually user self-inflicted. E.g., we remove a host out of the cluster to upgrade it or do something else with it and don't follow the correct procedure that's needed in order to be able to shut down the Zerto appliance correctly. If somebody doesn't follow that procedure, because they either don't know how, weren't aware of it, or just skip that step, then it causes problems inside of Zerto. This will pause jobs and the VPG will no longer be accessible on that host. Sometimes it's easy to get it back up and running again. Usually, when you put a new piece of hardware in the cluster that has a different set of parameters with its hardware, then the appliance will be missing because it was taken out with the old hardware. Usually, you need to get their technical support involved in order to be able to troubleshoot the issue with them to be able to get the VPG back online again on the new hardware. As I said its self-inflicted most of the time because steps are missed with our processes.

The documentation that we got from them was in depth and work well when needed, if you follow them correctly you will have success. If you don't follow the steps, that's when problems develop. Therefore, it's not a fault in their documentation, it's a fault of the user who's not following the proper steps for success. It doesn't happen often but I think we have contacted technical support only three times in the two years that we've had the product.

For eight years prior to using Zerto we used to use a product called SRM, which is part of VMware. We finally switched over to Zerto after having them come in and do a presentation for us. This was after trying for about a year to do that and convince our vice president to allow us to migrate over to a different platform.

The reason why we used SRM was because SRM was built into our VMware vCenter licensing. We never had a successful DR test during the previous couple of years with SRM. By switching over to the Zerto product a year and a half ago, we were able to run a successful disaster recovery test within three months of switching over. We had our first successful disaster recovery tests in two and a half years because Zerto made our life so much easier and helped getting servers over to a new location almost seamlessly. 

In order to be able to have a successful disaster recovery, we need to be able to successfully migrate 58 servers from our Massachusetts location to Arizona. On previous attempts, we got about half the stuff over there, then we'd fail. In other scenarios we would get everything over there but some of the machines wouldn't come up because of the way they were configured. One time, the business was down for about half the morning because it took us that long to get the stuff back up and running using SRM. This was a real pain point for us, getting this product in place and working successfully. It took Zerto to be able to finally get us to do that. It's been a lifesaver. All we had with SRM was nothing but headaches.

The initial setup was very straightforward. We had everything running in half an hour. It got deployed with two virtual machines (ZVMs): One got deployed in Massachusetts and another in our Arizona location. From there, we deploy appliances to each one of the hosts that's inside of the clusters that we are managing for our disaster recovery solution.

Within 30 minutes, we had it deployed to our entire production cluster and the hosts in here. After that, we just started creating jobs, which took quite awhile to do because we have a lot of large servers. However, that's not the worry of the Zerto application, but the size of the VMs we have in production. 

For our implementation strategy, we just mimicked what we had in place for our SRM environment. Our 58 machines are spread across different clusters: some in our DMZ, some in our prod and some in our WebSphere clusters. After that, we ran two tests to ensure that we were able to fail over to our Arizona location then fail back without any changes or modifications to the VMs. Once we did that, we started rolling out to each of the clusters, one Virtual Protection Group (VPG) at a time. I think we now have 23 VPGs total.

We worked with an outside vendor (Daymark) who does a lot of our work through outside vendors. They work with Zerto directly. When we set it up originally, we had a Zerto technician on the call as well as a Daymark technician on-site working with us.

Our experience with Daymark has been very good. We love working with them and try to use them for our integration and infrastructure work. They are a very good company that are easy to deal with. We try to use them as much as we can. Thanks to Rick and Matt for a great working relationship.

We have seen huge ROI.

It used to be a three-person job, and now it only takes one person to manage and run the process. The fall back is the same thing. We've never had any issues with stuff coming back out of Arizona to our Massachusetts location. Within 15 to 20 minutes, we can have our servers successfully migrated back, then up and running just as they were originally without having too many conflicts or configuration issues. 

The solution has helped us reduce downtime in any situation that we have come across, thus far, for disaster recovery at a 4:1 ratio.

We are an insurance company therefore, if we're down for an hour, it's thousands of dollars being lost. E.g., people can't pay their insurance bills, open new policies or get the support they need for an accident.

These things have been invaluable to us:

• Not having to have so many bodies onsite during a disaster recovery drill.
• Not having to worry about multiple people dealing with the application.
• The product's reliability of always being up and running and not having any issues with it.
  

It's very equitable, otherwise we wouldn't do it. It's something that we utilize for the licenses per host used. Therefore, it's very cost-efficient as far as the licensing goes. For the amount of stuff that we have configured and what we're utilizing it for, the licensing is not very expensive at all.

There is a one-time cost for maintenance and support. We have a three-year contract that we will have to renew when those three years come up. There is also licensing on top of that for whatever product you are using it depending on the host configurations.

Right now, we use Veritas. We will be evaluating Veeam and Rubrik as a new solution for our backups in the next quarter or so, on top of the fact that we may decide to use Zerto. The three of them are in the mix right now for when we decide to switch over vendors for a better backup solution. 

Zerto gives you the ability to utilize it as a backup solution, but it's not a true backup solution because it can't do file level backups. If you want a particular file off of a server, it can't do that for you. What it can do is give you the whole server, then you need to go back and pull that file off it. Mainly for that reason, we haven't chosen to use Zerto and may never use Zerto as our backup solution. The other solutions allow us to get a file level backup.

Don't hesitate. Go out and do it now. Don't wait two years like we did. Push harder in order to be able to get the solution in place, especially since we know it will work better for you. Don't just take, "No," for an answer from senior management.

The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.

We don't plan to use the solution for long-term retention at this time, but we are looking at going into a hybrid cloud solution in the near future which we may be using long-term retention for to make a duplicate copy of everything we have in our Massachusetts data center into a cloud solution. Whether it be an Azure or Amazon location on the cloud.

While I can't really speak to whether it would allow us to do it, the application is set up to create a duplicate of the actual servers in Arizona. That's how it works so quickly. If we ever had a problem, I could always revert back from the duplicates that we have out in Arizona using the application, if necessary. Luckily, we haven't had a need for that, and hopefully never do.

I would rate this solution as a nine (out of 10).

I use Zerto to monitor replication, configure protection, and manage disaster recovery and performance.

We implemented Zerto to manage disaster recovery and also for faster performance on backups and failovers.

Learning how to use Zerto can be easily achieved with some training and practice.

Zerto has helped us reduce downtime, retrieve backups faster, and manage our workload more efficiently.

Zerto has reduced downtime by 20 percent and helps protect the VMs in our environment.

It is 25 percent faster at recovering data compared to IBM Spectrum Protect.

Zerto has helped save four hours per week in recovery situations and has reduced our disaster recovery testing by 30 percent. We have used five percent of those savings towards other value-added tasks.

It has positively impacted our IT resiliency strategy.

Zerto enables disaster recovery in the cloud which is important.

Zerto provides real-time analytics and monitoring, enabling our organization to quickly identify and resolve issues. 

Zerto makes my work easier. Replicating my settings helps me recover point objectives faster and retain policies.

The most valuable feature is the customization that allows me to set my protection group myself.

While Zerto provides good service, I find the pricing to be high and believe there is room for improvement. I would like to see Zerto implement a pay-as-you-go model.

While Zerto offers scalability, its implementation can be more challenging in larger organizations, indicating room for improvement in its scalability features.

I have been using Zerto for three years.

I would rate the stability of Zerto seven out of ten.

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

The technical support responds promptly to our requests.

Positive

I previously used IBM Spectrum Protect but Zerto provides a quicker recovery time. With IBM the recovery process for particular data is manual but with Zerto it is automated.

The initial deployment of Zerto was straightforward and took two hours to complete. Two people were involved in the deployment.

We have seen a 20 percent return on investment.

Zerto is priced high.

I would rate Zerto eight out of ten.

Zerto is deployed in multiple departments and we have ten users.

I recommend Zerto because it helps recover data faster and improves its overall quality.

We use Zerto for multiple use cases. We are using it for disaster recovery, backup and recovery, and data protection. There is an inbuilt feature where we can utilize the Zerto platform in a hybrid model which means we have one instance on-premises and another instance on our cloud for redundancy and for cross integration.

Zerto’s near-synchronous replication works. We have configured near-synchronous replication between two different clusters. One cluster is on-premises, and another cluster is on the cloud. For near-synchronous replication, the value proposition is excellent. We are able to achieve the results for which we procured this solution. Near-synchronous replication is working perfectly. We do not see any challenges with data retrieval, complete replication, and synchronization processes. Everything is working perfectly and seamlessly.

We were able to see its benefits when we integrated it with our HPE GreenLake for DR purposes. It is a SaaS-based platform, so we are able to see the fastest way to recover data and applications. We were perfectly able to meet our recovery point and recovery times objectives through Zerto. On top of that, Zerto is protecting our data from ransomware, cyberattacks, cyber threats, national disasters, or human errors.

We are using a lot of virtual machines on-premises and in the cloud. Our main goal is to protect the complete data that we have in production and non-production clusters with different applications and big platforms.

Zerto is a market leader in continuous data protection technology. Previously, we had RPOs and RTOs in terms of minutes, whereas now, they have changed from minutes to seconds.

Zerto has an inbuilt disaster recovery protection and prevention with continuous replication. Whenever we faced any challenge related to our link being broken or not being able to access the data from the primary data center, all the backups were readily available because Zerto had replicated snapshots. We have not seen much latency or delay in recovery and the ability to get replicated data from different destinations.

We have not had any ransomware type of event. However, during the PoC and testing in an isolated environment, we have seen what would happen in the case of an attack. We could see how Zerto and its policies will take action and isolate that environment within a fraction of a minute or second.

For DR, we were previously using VMware Site Recovery Manager (SRM) but there was a lot of complexity. It was time-consuming. Most of the time, we saw a lot of human errors happening, and we were not able to test our DR activity. By leveraging Zerto for the past 14 or 15 months, we could achieve all of our desired results. There were no human errors. Everything went seamlessly. We are very happy with this solution.

Zerto has had a positive effect on our IT resiliency strategy. With the earlier vendor, we had a lot of problems. Our data got lost in transit during replication, snapshot creation, and recovery scenarios. By using this robust platform, we could achieve our resiliency metrics. The metrics are stable and never went below the benchmark.

Things are working perfectly. Each and every feature is complete with advanced options. It is a simplified DR operation platform. It has great visibility when it comes to protection from ransomware attacks. It has deep analytics features and robust data recovery policies. Everything is good in this platform.

The most valuable feature is the resiliency towards cyber threats for data protection. The main reasons for adopting Zerto are data protection and being able to do disaster recovery for site recovery. We can ensure that if the site goes down, data is available to all the users within a fraction of a second. On top of these, we have the resiliency towards malware and other security threats and attacks. Zerto has an embedded feature to protect our data from external and internal threats.

Zerto is very easy to use. It is very user-friendly. It is a GUI-based platform with a centralized dashboard where we can create policies, snapshots, replication policies, and disaster recovery policies. It is very user-friendly.

Patch management can be better. Although we are doing patch management on the Zerto platform in an automated manner, it can be improved by leveraging some AI-assisted technology. With the help of AI, things are going to be faster in terms of patching the solution.

We have been using Zerto for 14 or 15 months.

Since we deployed it, there have been no critical issues or major incidents. The platform is working as per the expectations. There was no downtime of any production activity. We are happy with the stability and overall performance of the complete platform.

It is completely scalable in terms of adding licenses, subscriptions, modules, and different sorts of features. Its scalability is seamless, and it is easy to use.

I have contacted them multiple times. Their support was good. We got a timely response and a timely resolution.

Positive

We were using VMware SRM previously. We switched from VMware SRM to Zerto due to complexity, cost, human errors, and data protection.

The most important security feature in Zerto is protection against ransomware attacks and internal or external threats. These capabilities were not present in the VMware platform. Cybersecurity resiliency and protection are embedded in Zerto.

Zerto is very easy to use, operate, and administer. It is very simple and easy to create and work on any of the policies and rules. It is easy to extract reports and navigate to the other tabs where we can see the health scorecard and other things. We can see all the things. It is very easy to patch the entire system. Everything is good.

We have a hybrid deployment. We have one instance of Zerto disaster recovery and protection running in an on-premises data center, and then we have another instance running on the cloud. Both are continuously replicated so that in case of any difficulty or problem with one, we can leverage the functionality of the other one. The on-premises one is taking care of the on-premises environment, and the cloud-based instance is taking care of the cloud-based environment.

Its initial deployment was very easy and flexible. We did not face any challenges. The solution is quite simple. It is easy to navigate, easy to use, and easy to migrate, although we did not go with any sort of migration. It was a fresh greenfield deployment, so we had no issues at all.

Its implementation took us about 12 weeks. It does require maintenance. The maintenance contract was already placed when we went with the purchase order for procurement. It was a multi-year support contract. It does require maintenance in terms of patch management, updates, health checks, performance tuning, policy updates, and recovery plans and procedures updates. We have a storage and backup team working 24/7 in this environment.

We directly worked with a Zerto system integrator. That integrator was recommended by Zerto. We also worked with the Zerto team for the complete architecture, framework design, implementation plan, and other things. We did not take any help from any third-party vendor or resource.

We had five to seven people for its implementation.

Its pricing is very competitive. As compared to VMware SRM, Zerto has reduced our OPEX cost by at least 30%.

I would rate Zerto a ten out of ten as a platform. With the help of Zerto, we have very enriched features for ransomware protection of all our data repositories. It provides great support for disaster recovery and response. Our RTOs have improved after adopting the Zerto platform, so everything is good.
