Zerto Reviews

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

I would rate Zerto a ten out of ten. 

Implementing failover to a secondary data center is crucial for ensuring business continuity in the event of primary data center loss. This strategy involves automatically redirecting operations and services to the secondary data center when the primary one becomes unavailable. This not only minimizes downtime but also enhances overall system reliability. 

The failover process requires robust synchronization mechanisms to ensure data consistency between the primary and secondary data centers. Regular testing and monitoring are essential to validate the effectiveness of the failover mechanism and identify and address any potential issues proactively. 

In summary, failover to a secondary data center is a strategic measure to safeguard against disruptions, offering a resilient solution for maintaining seamless operations in dynamic and challenging environments.

Zerto has significantly enhanced our organization's resilience and data protection capabilities. Its real-time replication and failover features have played a pivotal role in minimizing downtime during unexpected events, ensuring business continuity. 

The platform's automation and orchestration capabilities have streamlined our disaster recovery processes, reducing manual intervention and accelerating recovery times. 

The point-in-time recovery options provided by Zerto have proven invaluable in mitigating the impact of data corruption or accidental deletions. This has bolstered our data integrity and provided a safety net against unforeseen data-related issues.

The live failover tests and point-in-time recovery options have been exceptionally valuable features of Zerto for our organization. Conducting live failover tests allows us to validate the effectiveness of our disaster recovery setup in a controlled environment. This feature ensures that all components are in place and functioning as expected, providing confidence in our ability to respond to real-world disruptions. 

Additionally, the ability to choose a specific point in time for recovery down to the seconds is crucial for data integrity. This granular control allows us to roll back to a precise moment, mitigating the impact of data corruption, accidental deletions, or other unforeseen issues. It adds a layer of precision to our recovery process, minimizing potential data loss and enhancing overall resilience.

The product could benefit from improvements in automation, specifically in the area of failovers. Currently, the process is largely manual, and introducing automated failovers after a certain time threshold would enhance efficiency and responsiveness. Automated failovers can reduce the dependency on manual intervention, allowing for quicker and more proactive responses to disruptions. In the next release, the inclusion of scheduled or automated failovers would be a valuable addition. This feature would empower organizations to set predefined parameters and triggers for failovers, ensuring a timely and automated response to potential issues. It not only streamlines operations but also adds an extra layer of reliability to the overall disaster recovery strategy.

I've been using the solution for six months.

We did not have a solution before.

We had great help from the company in terms of setting up our environment.

We implemented through a vendor; I'd rate the experience ten out of ten.

Anything is the worth the cost for virtually no downtime. Time is money.

We did not evaluate other options.

It is a great solution overall, however, it could use some upgrades with automation.

We use the solution for replicating VMs from our on-site VMWare sites to both Google Cloud and Azure clouds. This allows us to feel confident not only in our disaster recovery capabilities but also in testing applications from our on-site data center to isolated cloud instances where there won't be any IP address or domain name system conflicts.  

The continuous backup gives us a better point in time recovery. It also reduces the amount of bandwidth to move the Zerto VM data from site to site, and we like that.

Zerto has improved our organization in several ways, particularly in the realm of disaster recovery, data protection, and business continuity.  

With Zerto's near-zero recovery time, our critical applications and services can be quickly restored, minimizing the impact on business operations.  

The data replication ensures that there is a consistent and up-to-date copy of the information. This helps protect against data loss and ensures data integrity.  With Zerto's single pane of glass, it's easier for IT administrators to monitor and manage their disaster recovery and data protection strategies. This has led to more efficient operations and reduced administrative overhead.

Zerto supports multi-cloud environments, allowing our organization to replicate and protect our important data across different cloud providers and sites. This flexibility has benefited our businesses with our diverse cloud strategies and our on-site data centers in different locations.  

Zerto helped our organization meet compliance requirements by ensuring data protection and recovery strategies align with our regulatory standards. 

Additionally, Zerto has incorporated security features to safeguard the replicated data.

Zerto needs to improve its documentation. It seems like some documents are copied from other older documentation, with misleading screenshots or incorrect steps.  

This can be confusing when newly introduced to a product or in a crisis situation such as a disaster recovery test or a true disaster recovery. The documentation needs to be revised, reviewed, and registered to be correct. Perhaps Zerto should consider an outside consultant to review and approve any documentation that is released.

I've used the solution for about a year.

It's very stable, and we have had no issues.

it does scan well and does what it claims to do.

Support needs to be more flexible.

Neutral

We have only used vRealize.

The documentation was confusing and, at times, incorrect.

We handled the setup in-house.

I don't any ROI information.

I'd advise others to start small.

We also evaluated Veeam.

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 use it mainly for our disaster recovery, so we replicate our production VMs between our data centers.

The solution meets our high availability and disaster recovery needs.

The disaster recovery reviews itself and it has the ability to fail over within seconds and get new machines up and running on a new data center in a matter of minutes.

It's pretty easy to use. It depends on how detailed you get into the product. If you get real detailed into the product with some of its backup capabilities, it can get a little bit more detailed, for example. However, for the disaster recovery piece itself, it's it's pretty easy to use.

The near synchronous replication is effective. It works really well. The replication and the RTO, RPO times are pretty much the best in the industry.

We saw some benefits right away in that we were understanding that we were now highly available. We also started to see more and more benefits as time went on.

It helps protect virtual machines in our environment.

Our downtime and our ability to replicate happen within seconds. We've seen other products that take about five minutes. Now, we take seconds to get things back up and going. Therefore, the loss of data is virtually nothing. We've been extremely happy with that. 

It's helped reduce downtimes in pretty much any situation. We've had instances where a data center or a cluster in a data center was down or we were having problems with it and being able to have that replicated data being able to be spun up within a matter of minutes. It's significantly helped where if we didn't have that ability, we were probably looking at at least three to four hours, if not a day, of downtime. We're talking about the difference between minutes of downtime versus hours to potentially days.

With Zerto we haven't had any any actual instances where ransomware or anything like that actually comes up. We do yearly testing where we'll fail over an entire data center. While we haven't had any malicious incidents, we've had success with conceptual testing.

Zerto hasn't necessarily reduced the overall testing in our organization. We still have to do the testing. That said, it's reduced the time in which it takes to perform that testing. So, we still have our requirements to do yearly testing. However, it's at least reducing the amount of time it takes. Before, the testing would take an entire weekend and multiple departments in order to complete it. Now we're finishing our testing in a matter of hours. We're knocking off quite a bit of time with Zerto - plus hours of time in order to complete testing.

Zerto is now our resiliency strategy. We're able to replicate all of our data and be able to bring up an entire data center within a matter of minutes, which has become our go-to for our resiliency within both of our data centers.

Recently, they started forcing everybody to use a Linux-based appliance for their z/VMs. That appliance has been extremely touchy and, in some cases, problematic. However, there were Windows-based z/VMs prior, and we never really had issues with them. But now we're running into problems where certificates aren't able to be imported for things like LDPAPS and SSL. We've run into actual downtime with the z/VMs recently, which is new to the Linux app appliance. Overall, the appliances had some bugs, and they've not been as reliable as they were in the past.

I've been using Zerto for a little over 4.5 years.

There are the no real lag issues, We've only had a couple of instances where the system has been down, and wasnew since our Linux appliance install. Overall, it's been pretty reliable with the caveat that the new Linux appliance has had some downtime. Prior to that, we hadn't had any. 

Scalability's been good. There's a couple of instances where they could allow for some more local replication, however, scalability has been good.

I quite frequently contact technical support. On most things, they have been pretty good. The issues that we've had with that z/VM, those tickets can take quite a while. I have one ticket that's been open for about four and a half months now. They're still trying to figure out some of the bugs within their system, which has caused some tickets to take longer than they really should.

The quality of response has been pretty good. Maybe 7  or 8 out of 10 are quality responses. They're they're pretty good, pretty knowledgeable. Again, there are some instances where they're still learning the system as well, or there's something new, and it's a little bit odd; however, other than that, their answers are typically pretty spot on and pretty well documented.

We used to build products by Nutanix. Their RTO times were much higher. That's about the only solution that I've used at least recently.

I wasn't part of that decision making process. Zerto had been onboarded by the time I came on to to the team here.

The deployments have been pretty easy as long as you have your network topology figured out. If you're just starting up a brand new appliance, and you're running through a setup, signing IPs , et cetera, you have to make sure that the z/VMs can talk to each other. It's a pretty easy process.

Usually, for the setup, we have the SME, which is me, and then a backup to be a second pair of eyes, however, a lot of the work is been done just by myself.

In terms of maintenance, there are updates that need to be applied. The certificate imports need to happen depending on expiration dates. There also is their key cloak integration for authentication, and that requires some upkeep as well depending on how you're signing permissions and what you're signing permissions for.

I've done redeployments myself, for example, when we switched over from Windows to Linux to z/VMs. That was all in-house. At the time when they did their very first deployment, they had used a third party vendor to assist with that. We've not needed them since. 

I don't have any visibility on the pricing. 

We're a Zerto customer.

I'd rate the solution eight out of ten. 

New users need to understand the product prior to deployment and make sure that they're taking the time to whiteboard this out. Your VRAs are going to take up a good amount of space. So users need to understand that when you're replicating data over, you are making a second copy of that data, and understand what your test scenarios are going to be. You need to understand if you need things like a test environment to actually be within Zerto since that will be taking up more space. Overall, people just be aware that the Linux appliances still have to have their bugs worked out. For first-time users, especially, I would keep those deployments as simple as possible to start.

We use Zerto for disaster recovery and resilience in our application. It helps with data protection, database recovery, and workload mobility.

The main benefits of Zerto for our company are disaster recovery, workload mobility, and end-to-end ransomware protection for our data.

The most valuable feature of Zerto for us is its DR capability. With Zerto, we can easily recover data in case of any incidents, minimizing the risk of data or information loss and ensuring the security of all databases within our applications.

Improvements in Zerto's user interface and the addition of advanced features such as artificial intelligence or machine learning for predicting ransomware attacks and workload requirements would be beneficial. This could help mitigate potential issues like computing pressure on our applications.

I have been using Zerto for 2 years.

Zerto is quite stable and mature.

Zerto is scalable, allowing easy configuration to meet changing needs. If user demand increases, adjustments can be made to ensure smooth application performance.

We have occasionally contacted Zerto's technical support for clarification on features and compatibility issues. Overall, the support has been good, with timely solutions provided for issues. I would rate them a 9 out of 10.

Positive

Compared to other disaster recovery solutions like VM-based software, we found Zerto to offer better speed of recovery, pricing, features, and overall protection.

We switched from VMware to Zerto due to pricing constraints and incomplete feature requirements. Comparing ease of use, Zerto was preferred over VMware as it offered better pricing and compatibility with HPE, a part of TechGuard Enterprises, which aligned with our infrastructure setup.

The initial deployment of Zerto was smooth and simplified by the support and consulting team's expertise and friendliness. We had a team of 4 people involved, including 2 technical architects, myself for project planning and implementation, and a Zerto support person for function control and time management. No maintenance is required on our end after the deployment.

Zerto has had a positive impact on our RPOs. We have seen a return on investment and are satisfied with the product's overall value. The ease of deployment and user-friendly interface contribute to a seamless experience with Zerto.

We find Zerto's licensing model compatible with major cloud providers like Google, AWS, and Azure. The Azure pricing model is particularly cost-effective for us compared to other cloud providers. Additionally, we appreciate the quality of support and solutions provided by Zerto.

We implemented Zerto to address challenges with ransomware and protect the personal information of our large user base. We needed a solution for ransomware protection and data protection.

Zerto is user-friendly and compatible with major cloud providers like AWS, Azure, and Google Cloud. We find it particularly convenient as a managed service on Azure, where we can easily enable and configure it for our applications.

Near synchronous replication with Zerto performs well, especially after HPE acquires TechGuard Enterprises. We are satisfied with their customer support and end-user support services.

We use Zerto to protect three virtual machines in our environment, each running a different application. Zerto ensures that all three virtual machines are fully protected.

Zerto has significantly reduced downtime for us as it operates in real-time without requiring any downtime for database or application protection. Simple configuration with our applications and databases is all that is needed.

Zerto has saved us time in data recovery situations, particularly from ransomware attacks. It provides comprehensive insights into attacks on our databases and applications, enabling us to take immediate action based on real-time reports and analysis of logs.

Zerto has streamlined our DR testing process by offering a DSO option within its configuration design tool. This feature simplifies the setup process and saves time without requiring technical expertise.

Zerto has positively impacted our IT resiliency strategy by aiding in the creation of comprehensive IT roadmaps. It assists in planning for application and database deployments, as well as implementing security solutions for protection against ransomware and data disasters. This early-stage planning helps us align our roadmap effectively.

New users can confidently use Zerto for their disaster recovery, virtual mobility, and ransomware protection needs without hesitation. It is a highly recommended software for ensuring data security and business continuity.

Overall, I would rate Zerto as a 9 out of 10.

We use Zerto for offsite disaster recovery. We have over 70 VM servers, several of which are our mission-critical servers that are replicated to our VMware hosts at an offsite location. 

We also replicate our Citrix environment and Disaster Recovery Zen App servers with Zerto to our offsite location as well. Most of our servers are Windows-based operating systems. However, this doesn't matter because we are replicating the VM servers. Further down the line, we may invoke extended retention for some of our more important servers.  

It gives us peace of mind that our data, servers, and environment are protected. We can easily restore VMs quickly and have confidence that the replicated data will be current. 

We are able to show proof in tests, reports, and live data to our owners, showing that our most sensitive data and servers are being replicated to an offsite facility, and we can restore it in case of a natural disaster or from our system being compromised by ransomware. 

Our IT staff can easily navigate through Zerto and test failover, see if there are issues with replications, and create offline copies of the data. 

Being able to test our VPGs and prove that our disaster recovery setup is in place and functional. 

Our business owners can be assured that our data is protected, and in case a serious problem occurs, they know that we will be able to recover easily. 

Zerto is fast to restore our mission-critical servers when needed. We also use Zerto to make copies of our VM servers for our offsite Citrix Zen App Servers. Zerto has helped simplify the process of disaster recovery setup and made the tasks more efficient for our IT Staff.

Zerto could add text alerts if there are critical problems and alerts if changes affect our replication. We do receive emails, and they will alert us to issues that we are having with VPG SLAs. 

I don't have any complaints about Zerto, and I hope they continue to develop new features. If they had classes on using Zerto, that would help with onboarding new IT staff. They may already have them, and I am not aware that they do. Overall, Zerto works out great, and they do a good job. 

I've used the solution for five years.

Our primary use case is for disaster recovery. We replicate up to Azure, and that's essentially disaster recovery as a service.

Overall, the effects of RPO have been great. They are never more than a minute or two, even throughout the production day.

If we can replicate from our native VMware environment up to native Azure, it converts the machines for us. We don't have to maintain another VMware environment somewhere. It's really given us the ability to eliminate the entire data center.

Moreover, there are cost savings tied to this. We don't pay for the rack space, power, or hardware; all of that is gone. Because the machines aren't active, all we're paying for is storage in Azure. So it has saved us quite a bit of money.

Zerto's near-synchronous certification has positively impacted our operations. Any recovery point that's too far in the past, we'll lose transactions when we fail over. We really don't want to do that. Real-time replication gives us a much better sense of security for the enterprise. It simplifies things for us and reduces costs.  It makes management feel really good, too.

Using DR in a cloud environment has been a positive experience. We're saving money. We don't have to maintain the hardware. We don't have the rack space at the other data center. It just simplifies things for us and reduces costs. It's been a positive experience overall. It's pretty easy to use. Once it's up and running, it stays running. We have had a few times when we called support and the support has been very, very good.

Maybe the reporting for the failover test could be a little better.

I have been using Zerto since 2020, so it's been three years.

It's very good. It's very stable. It doesn't require a lot of intervention. 

We haven't had any problems with scalability. We have 75 machines protected by Zerto and it does a fine job.  

Support has been very good.

Positive

We used to use Site Recovery Manager when we had two data centers, and it was VMware to VMware. We were using EMC storage. Zerto is a lot easier to use than Site Recovery Manager. It requires less care and feeding. 

Site Recovery Manager occasionally would lose virtual machines, and it was kind of a pain, but Zerto just kept running. So overall, we're really happy with the switch to Zerto.

The initial setup was easy.

Since we don't have to maintain all of the hardware and the second data center, one person can manage the entire Azure environment by themselves. As a result,  Zerto has helped us reduce staff. 

We did an assisted setup with Zerto tech on the line, and It was really painless. It was simple and straightforward. The initial process including getting the servers and everything set up, was pretty short. The process included getting the VMs all added to the recovery groups and things like that. 

The whole process from start to finish took less than a week.

It has proven to be a cost-effective solution for us. 

It could always be less money. 

Overall, I would rate the solution a ten out of ten. It requires little care and feeding. Not a lot goes wrong with it. It just works.
