Zerto Reviews

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 currently utilize Zerto as our disaster recovery solution. With Zerto, we replicate production virtual machines to our DR site. This approach enables us to recover and bring everything back online in a disaster swiftly. Our recovery point objective can be as low as five seconds, depending on the replication point.

Additionally, we employ Zerto for scaling purposes and for conducting upgrade testing. This entails spinning up VMs in an isolated environment, allowing us to perform various tests. For example, a few years ago, we tested the upgrade of our active directory domain controllers. By validating processes within this environment, we can ensure their smooth execution in production. These are the two primary use cases for Zerto in our organization.

Zerto is very user-friendly. We can select the VMs by installing a small agent specifically designed for the host. This agent identifies all the VMs. Zerto integrates smoothly with VMware, which is our primary core platform. I believe it also functions well with other hypervisors, although I am only familiar with VMware. Therefore, the integration with vSphere simplifies the process of creating groups, runbooks, and other components necessary for building our disaster recovery environment.

Zerto's near-synchronous replication performs admirably. Many times when I check, we are only about five seconds behind in terms of production time. Of course, this does depend on network performance. There have been instances where the delay exceeded five seconds due to network blips or other issues. However, for the most part, we consistently remain within a five-second range of our production environment.

As a manufacturer, a significant portion of our operations relies on timely execution in order to ensure efficient production and timely delivery of our products. We closely coordinate with external partners and customers to minimize downtime and maintain a seamless real-time production process, which is crucial for us.

The ability to conduct faster disaster recovery testing and the potential for quicker recovery in the event of a disaster have been greatly improved. Before using Zerto, our approach involved log shipping and manual recovery, which meant that the best we could do was recover the previous backup from the previous night, assuming the backup was successful. This process would take hours or even days. However, with Zerto's automation, we can now recover within seconds—five, ten, or twenty seconds from the point of the outage. We can bring systems back online automatically and at a significantly faster pace than our previous manual approach allowed.

Zerto has significantly improved our recovery time objectives compared to what they used to be. Previously, we would have to restore from backups from the previous night and manually configure systems. Therefore, the recovery time objective has likely decreased from days to approximately an hour, or perhaps even less. It's challenging to determine the precise timeframe in a real disaster scenario since we conduct disaster recovery testing. However, it is undoubtedly much better than it was before, although pinpointing the exact time of an actual disaster is somewhat different.

Zerto has helped us reduce our organization's disaster recovery testing from several days of preparation to just a single day.

Zerto is easy to configure and manage. The ability to quickly bring up VMs within a test environment allows us to test our disaster recovery functions and ensures that they would function just as well in an actual disaster scenario. This enables us to swiftly recover in the event of a disaster.

Zerto could be easier to configure when we need to perform data testing and establish network connectivity outside of the isolated environment. We encounter situations where there is a desire to test a printer during disaster recovery testing. However, due to the presence of an isolated environment, doing so can result in complex configurations. 

Zerto needs to improve its support for VMware Lifecycle Manager. This creates a problem with VMware's ability to automate the complete VMware stack upgrade.

I have been using Zerto for ten years.

Zerto is highly stable. It is rare to encounter any issues with it. Typically, any problems that arise are due to changes made on our end that may have inadvertently affected it. However, Zerto remains an exceptionally stable product.

To the best of my knowledge, Zerto can scale to the extent that we require. I am not aware of any limitations, as we have not encountered any thus far.

The technical support is generally very prompt in responding, and highly knowledgeable, and they will continue working with us until the problem is resolved.

Positive

We previously used Dell RecoverPoint for Virtual Machines and completely replaced it with Zerto.

Zerto is much easier to use compared to RecoverPoint. Previously, with RecoverPoint, we could only program-specific logs, and the VMs we wanted to replicate had to remain on those logs. If we moved the data off those logs, replication would be lost. However, Zerto keeps track of the VM regardless of its location, making it superior to RecoverPoint in terms of configuration and management.

Zerto is a more cost-effective product than Dell RecoverPoint.

The initial setup is straightforward. We need a virtual machine, install it, push it through, and configure it to communicate with the host for deployment. I mean, it's a very straightforward process. Two people were involved in the deployment.

The implementation was completed in-house.

The human resources necessary to perform a disaster recovery test are undoubtedly available. It is more economical than RecoverPoint. Now, it has been many years, and I am uncertain about the cost disparity. However, on the whole, there is a decrease in various aspects regarding the product's cost and the number of work hours needed for disaster recovery testing which is a clear return on investment.

The pricing is straightforward. We are on an enterprise licensing model, and it is based on a per-VM basis. We have the option to purchase them in blocks. This approach is quite cost-effective as we do not replicate our development and testing environments. We only replicate the production environment. Therefore, we are not paying for the entire setup, but only for what we are actually replicating.

I rate Zerto a ten out of ten.

Currently, we have a separate product that we use for backup, which has immutability features. However, we do not currently employ Zerto for immutability purposes.

We have considered using the cloud for disaster recovery, but currently, we maintain the same hardware at both locations. However, since we conduct all of our firmware testing and upgrades on our disaster recovery site first, we have decided to keep our own disaster recovery site instead of attempting to do it in the cloud.

We could easily transfer data to the disaster recovery system. One of Zerto's functions is to replicate data from virtual machines or migrate entire virtual machines, although we haven't utilized it for that purpose.

The only maintenance required is typically software updates. Whenever a new version is released, we must go through the process of upgrading Zerto. Other than that, unless there are any issues, it generally operates smoothly.

We just need to ensure that we know the number of virtual machines we would be replicating so that we can obtain the correct licensing. Otherwise, we will have to backtrack. If we underestimate, we will need to provide additional licensing. It is important to determine this information upfront, as well as the bandwidth between our site and the replication location, as it also affects our recovery objectives.

We primarily use Zerto for disaster recovery and business continuity. We have also used it significantly for transferring workloads between different environments.

Zerto's Near-Synchronous Replication is very important and was one of the main factors that drew us toward the solution. Some of the other solutions now have a similar feature that wasn't available before or doesn't support RDMs that we use. Fortunately, we haven't been hit by ransomware, but if we ever were, Zerto would be a great help. The fact that we would be able to easily pick a point with minimal data loss compared to having to go to a backup is a major advantage. 

We have definitely been able to do some functions that we wouldn't have known how to do without Zerto. For example, we get hardware refreshes every so often. We are still using Dell VxRail, but for some of our clinical workloads, we created a new cluster for PACs and radiation oncology. We had to move many workloads from Dell VxRail to this dedicated cluster, which was traditional SAN. Zerto saved us in this situation, as we were able to start a VPG and move the workloads. Additionally, we have different data centers, and if someone decided they wanted the workflow to run in a different data center, Zerto saved us a lot of time by not having to rebuild the system. Lastly, it gave us the ability to test failovers with staff to prove that it would work before we had to trigger a live migration.

We primarily use Zerto to protect our virtual machines.

Before we found Zerto, our backup environment was so slow that it could take multiple days to recover certain servers. This was not practical, so we looked for a better solution. Zerto has had a much greater effect on our Recovery Point Objectives than we could have achieved with any other solution before it. We could have potentially lost a day's worth of data, whereas with Zerto it is only a matter of a few seconds. Therefore, for any critical workload, Zerto is the best choice.

Our only other option was to recover from a backup. We found that for larger VMs, it would take days to do that compared to using Zerto. Zerto would spin up in a matter of minutes, and with the recording running through testing, we had the actual times recorded that we could accomplish all the tasks. It was drastically different.

Zerto has helped us reduce our DR testing. Before Zerto, we never had a DR test plan. It is still a work in progress, but Zerto makes it much easier to test functions as we can get reports on the test runs. This makes it easy to hand over to someone explaining the details of how long it took. Whenever we have done testing, it has been easy to perform and not very time-consuming.

Zerto's ability to test failovers with a record of how long it takes to fail them over is beneficial, as it allows us to know the timing in the event we have to do it live. Additionally, the support and RDMs, which many products do not have for this type of workload, are useful. Furthermore, the ability to easily move something between different sites and the general ease of Zerto is great.

Zerto's ease of use is the best I've seen. We initially looked at different options such as Veeam Backup & Replication and VMware SRM, but Zerto appeared to be the most straightforward. We have had other options come up since then, but they are not nearly as user-friendly as Zerto. Zerto is quite straightforward.

The only challenge we have encountered is with rotating passwords on our VMware nodes. With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the VRAs. This is not ideal, especially when our security team wants to rotate them weekly. Aside from that, everything has gone smoothly. The updates are easy and it does not hinder us when updating the VMware. The only issue is that we have to wait three months after a major release. This lessens the complexity of the update of the software itself. Other than that, there is no issue and it does not hinder us from running different versions of VMware.

I have been using the solution for over five years.

Zerto is stable and we have never had any issues.

We have not increased our original purchase, but Zerto would scale if we needed it to. As new projects came along, we were supposed to identify if Zerto would be a use case. We have enough licenses for everything that has been added so far. We do eventually want to go into the cloud and potentially add more workloads, and Zerto seems to be sufficient for that.

I always find the technical support to be quick in responding to us, and the issue seems to be resolved almost instantly. It has been nothing but positive with support. They are definitely one of the better companies to deal with in terms of support.

Positive

The initial setup was straightforward. We had someone from Zerto come down and set up the system in just a few hours. They provided us with knowledge transfer on how to create VPGs and other items and gave us an overview of the architecture of the whole solution so that we were confident in managing it ourselves. We have done all the updates ourselves.

The full deployment including the planning phase took a couple of weeks and required a few people.

The implementation was completed in-house with the help of a Zerto specialist.

Zerto has been more of an insurance policy. We haven't had to use it yet, but if that day ever comes, it will be invaluable. Zerto has already helped us in other areas, such as moving workloads, which has saved us a lot of time that would have been spent rebuilding and decommissioning. more of a safety net.

We do renewals and haven't added any additional licensing yet. When we purchased Zerto, we felt it was worth the cost as it would protect us from any potential problems and give us peace of mind knowing that any critical items could be recovered quickly.

I give the solution a ten out of ten.

When we bought Zerto, our goal was to be able to failover to the cloud. However, we have not yet fully adopted the cloud, so we have not yet upgraded our license or paid any connection fees. Our goal is to upgrade the license once we are ready, but that has not happened yet.

Zerto's ease of use, and straightforward use, is the reason we chose it over other solutions. We don't want to be in a situation where, during a crisis, we have to hunt around and try to figure out how to use something. It's nice to have something that is straightforward and easy to use, instead of adding stress to an already stressful situation.

We are still using other products for backups. We have not really ever used Zerto for backups. I know Zerto has changed its licensing model, but when we initially started using Zerto, we had to license every VM for basic protection, which was more costly than other backup solutions. I know Zerto has changed and we can now buy a backup license for VMs. However, due to the time, we are locked into a certain backup product, we will look at other potential solutions when the contract expires.

We have Zerto deployed across two of our data centers.

We have one person that maintains and monitors Zerto with an additional person who acts as a backup.

The maintenance consists of updates and tweaking of journals for VPGs.

If we have any specific use cases that we want to discuss with the Zerto team, they will often arrange a peer meeting with organizations. Zerto did that for us when we were using Meditech MAGIC so that we could make sure that anyone else with experience running it could help us. We were able to do a trial run with Zerto to get confident. I suggest taking advantage of doing a trial to make sure Zerto meets our needs, and if we have any unique workloads, then talk to the Zerto account team to try to arrange a conversation with someone else who is doing the same thing.

Our primary use case for Zerto is for disaster recovery. In the last few versions, they've offered backup, but we don't use it because it's not nearly as robust as what most of our customers are looking for. We also use it for migrations too, to migrate customers into our cloud, and things like that. But that's around 20% of our use case.

Zerto has enabled our growth. Five years ago we had around 20 customers and now we have 500. We protect around 15,000 VMs now.

One of the most valuable features is the analytics portal. It's still an evolving feature and has ways to go but we use that for monitoring because we have hundreds of sites. It's nice that all the alerts and everything is consolidated into that one site because we used to have to make sure that we were connected to many, many sites to make alerting work, which was a nightmare. 

Our alerting is done through scripting too. They do have pre-canned alerting through but is not very robust and they're working on it. They actually included us in the study on it. For instance, if you were to have a problem at a certain site or something, there's no way that you could take it out of monitoring. If you were using their system, it would just flood you with alerts from all kinds of stuff from the site if it was down. It is great if a site is down and you don't expect it, but if you have planned maintenance, you don't want all of this coming in.

There are a lot of valuable features. The basics of what it does to replicate and recover things within minutes is awesome. It's far above anything that any of the competition has. We offer other disaster recovery software but primarily use Zerto for recovery times and the number of recovery points because of how fast and easy it is. It's so much better.

We reduced the number of people involved in recovery situations by using Zerto. We had another solution before and we had a small number of customers and it took the whole team to manage 20 customers. Now we have 400 to 500 customers and our team is relatively the same size. We're broken up into different teams, but when we managed it all ourselves with only 20 customers, we had four people. And now we have around 500 customers and we have around 20 team members.

Zerto has a really robust PowerShell and scripting that you can get lots of numbers out of but it's not exactly the easiest thing to do. Zerto has a few nice pre-canned reports but there is a need for more. Unless you script something, it's difficult to go in, click a button, and see the information that you may be looking for.

The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited.

Zerto is very easy to use on the surface, especially if you're an enterprise customer, which is just like A to B replication or one site to two sites. As a cloud provider, they still have a lot of work to do. But for most customers, it would be fantastic. We have a lot of private clouds that are one site or two sites. So when it's not meshed like our larger environment is, it works fantastic. But when you get into the overall fully meshed model with vCD integration that we have, it doesn't work as well. I think Zerto is mostly concentrated on the enterprise customer and left the cloud providers by the wayside.

With the HP acquisition, product development has certainly accelerated. They recently released the first major half release and have put additional focus on cloud providers. Unfortunately, the major focus remains on Enterprise. Next year, they will force customers to move from Windows management VMs to Debian Linux. I can only hope they have a well-thought-out migration tool. My fear is that the cloud provider will be a secondary thought once again.

The major issue with Zerto development is that they refuse to patch the current software release and only patch the newest release. When you hit the bug, they expect you to upgrade right away. This is not an issue if you only have a hand full of sites. The issue when you have 100s is that there is no way to skip a minor release. Every multi-tenant customer you have must be upgraded to every minor release. Two to three upgrades every year for every customer is very intrusive and requires way more management effort than should be necessary. We often have a hand full of customers delaying the upgrade cycle and are forced to discontinue service to those customers. HP can surely develop a better model.

I have been using Zerto for six and a half years. It's deployed on-premises, on the cloud, and we use it as a SaaS offering. We are the cloud provider. We also integrate with AWS and Azure.

It's a very stable solution, for the most part. They have a new release every six months and some releases are better than others as far as bugs. Sometimes those bugs have to do with something in Hyper-V, and sometimes they have something to do with VMware or vCenter. But many times, it's directly related to Zerto's problems. Usually, their major releases go in .0 and .5. The .0 releases have the new features in them and they're more buggy and the .5 releases are more stable.

It's extremely scalable, in a small sense, but the problem is when you get very meshed, with 10 sites replicating to 10 sites, and each one of them is meshed in to be able to replicate it to the other one. Then scalability starts to become problematic.

The big thing is, we have a cloud manager that manages all our ZVMs, which enterprise customers probably wouldn't have. You can only upgrade half a release for each upgrade. So you couldn't go from Zerto 6 to Zerto 7. For instance, you have to go to 6.5 and then go to seven.

Trying to upgrade is not easy because every customer that's paired and replicating into those sites has to upgrade it in those steps. It takes us several months, twice a year, to get everybody upgraded. They have a portal called Cloud Control which makes things better as far as upgrades, but they recently broke it with version 7.5 by adding encryption. So it was useless. We just upgraded to a version in which it should be working again, so the next time we're going to try to use Cloud Control to upgrade. Hopefully, it will be better. We only really have one round of upgrades through Cloud Control to get an idea of how well it worked. 75% of the time, those upgrades work without problems.

There was a time when they had customer service people just taking tickets and they couldn't really help you at all, which was terrible. Now, they have a level-one level-two-type model. The level-one guys are getting better, but as they grow, it can be difficult. 

All of our engineers are certified and we would like to go straight to level two. A lot of times we waste a lot of time with level one, and then they put the ticket in the queue for level two. So it takes another day to get to level two unless we're really loud and escalating the ticket right away. The biggest problem that we have with Zerto is getting to level two. 90% of the time, because of our knowledge, level one is not useful to us. Although, it probably would be to the average customer. 

Zerto really needs support dedicated to CSPs and large customers.

Positive

We switched from our previous solution because Zerto was so much easier than everything else that we saw. We have a team that does the tests. It was a pretty easy choice to move away from those platforms at the time and those platforms no longer exist. Today there are many alternative DRaaS solutions and we offer many of them. Zerto remains more mature and feature-rich than the competition though.

The initial setup was pretty easy. You have to have connectivity between the sites that you're replicating, your production, and then your DR site or sites. Getting that connectivity is the biggest thing. Once that connectivity is there, it's fairly simple. You deploy Windows VM, put a small software package on it, and then pair the two. You do the same thing at the recovery site and once those sites are able to talk. In VMware, you install a VM on each ESX host that you need to replicate a VM on. Then you create a policy to do that replication. The replication policies work very well. Re-IP on failover if problematic.

The network connectivity takes the longest. It can take weeks, depending on what you have to do to connect the sites. It could be a couple of hours if you're just setting up a VPN. If you're putting in a circuit, it could take a very long time. That's the X factor with it, but assuming that's already there, within an hour you could be replicating data from one site to another.

ZCCs remain a major stumbling block. If the routing table has issues, the only fix is to delete all protection, redeploy the ZCC and rebuild. Again, avoid Zerto Cloud Manager until the product matures.

We implemented the solution in-house.

We have seen an ROI. Otherwise, we wouldn't keep using it. The biggest thing is the number of VMs we can support with the staff that we have. 

The licensing is fair. We have an enterprise license in which Zerto gives us 20,000 licenses or something well above what they think we're going to sell for the year. Then all our customers pull from that pool and we resell the licenses. We may sell 50 licenses to a customer but at the start of their contract, they may only have 30 VMs ready for DR. We contract them for 50, but eventually, they'll get up to 50. So we don't have to go to the vendor and add and remove one license here or one license there all the time.

That part of it is easy, but we do have to license all of our sites once a year, which is a pain and all of our sites report to Zerto Analytics. I've been asking them for years since they started Zerto Analytics, why we can't just put our license key on analytics rather than logging into hundreds of sites and putting them in each site. That's a real beast. They definitely need to fix the part where the site licensing is terrible. As far as the licensing VMs to replicate, that's great.  In version 9, Zerto plans on deploying a license server to address this.

Zerto 9 is out and there is still no customer-deployable license server. We regularly have issues with customers who cannot reach the Zerto license server. They cut you off at the knees after 14 days! HP really needs to work on this process.

Commvault was one of the big ones we looked at. Commvault is much more complex and expensive. We also looked at AWS and Azure. We offer a wide range of solutions. 

Recently launched last year, Nutanix LEAP is primarily designed for people that use Nutanix, and not everybody does. Not everybody can use it. We also offer RecoverPoint for VMs. It is a Dell EMC product, so it's geared toward people that are running VxRail. And then there is vCloud Availability. You have to have vCloud Director on both sides and vCenter, which is not something that everybody has either. vCloud Availability monitoring is also a nightmare. Zerto is more the product of choice for most use cases. 

Some of the biggest problems that we've had as a cloud provider are the vCD integration and the Zerto Cloud Manager integration. If you can avoid those two things, avoid them.

I would rate Zerto an eight out of ten. 

We primarily use Zerto for disaster recovery and backups.

When we use our VMware environment, sometimes the HP hardware is not compatible, and we start to lose data. I like that we can restore our whole application and public-facing system through Zerto.

It's the easiest way to do disaster recovery. It's less complicated than VMware.

Compared to the ease of use of other DR or backup solutions, Zerto's dashboard is the easiest. The user interface is much simpler, and maybe, that's what makes it easier.

Zerto helped reduce downtime when our data is corrupted. We're able to restore it relatively fast. There may be downtime of about half an hour for us, but the users don't see it; it's transparent.

The speed of recovery with Zerto versus the speed of recovery with other DR solutions is about the same.

Zerto reduced the number of staff involved in DR situations. We went from ten people to two for the whole organization.

It also reduced our organization's DR testing by about 30%. We've actually been able to move a lot of our resources (people) to AWS Innovation.

Zerto can improve the dashboard by making it even more simple. Right now, there's a lot on the dashboard, and it can be overwhelming. If you're an experienced user, then you'll find it easy to use, but if you're a beginner, it will take you some time.

We've been using it for seven years now.

Zertos' stability is very good.

It's very easy to scale, but the only problem is that there are additional costs associated with it. 

Zerto's technical support is excellent. When you open a ticket, they get back to you right away. If you mark it as a priority, then you have instantaneous access to support. I would give technical support a nine out of ten.

We have VMware products and tried to implement VMware Site Recovery Manager. However, it was just a little too difficult for our environment.

At first, the initial deployment was complex, but now it's relatively easy. For someone experienced, it is not a problem.

We have five data centers, and we started with one and deployed it in phases. Because there are lots of firewalls and access, we picked one data center and then built the next one.

We implemented it ourselves, and it took about a year to deploy it across the whole system.

For a long time, we needed disaster recovery that was more than IBM's, which is in Colorado. We needed something on-premises that was instantaneous. That's what Zerto offers, and that's the ROI we have with Zerto.

The last time I looked at pricing, it was very good. It's much cheaper than VMware by far.

We looked at VMware Site Recovery Manager and IBM, but they didn't work well.

The best way to look at it is from an ease-of-use standpoint because when you look at VMware's version, it's a little bit more complex even though it is native to where we use it. That's why we went with Zerto.

Considering what we use Zerto for, I'd give it a ten out of ten because it is our primary solution.

We use Zerto for our application data recovery.

Zerto's near-synchronous replication delivers exceptional results. The data at our recovery site is kept nearly identical to production in real-time, minimizing data loss to near zero.

By utilizing Zerto's immutable data copies and adhering to the three-two-one rule, we have established a highly effective recovery strategy.

While Zerto doesn't inherently block unknown threats or attacks, its detailed history logs enable us to revert to a pre-attack state, essentially restoring a clean system.

Our production machine experienced changes that caused the application to crash. To resolve this quickly, we restored the machine to its previous state using a recovery copy located at the recovery site that was made by Zerto. After powering on the restored machine, we changed its IP address, making it accessible again.

Zerto has a positive effect on our RPOs.

It boasts impressive recovery speed. As a customer, all we need to do is power on the machines at the recovery site - that's how simple and fast it is. Even if the recovered state isn't ideal, we can easily rewind to a specific point in time and power up another instance of the machine at that moment.

Zerto makes it easy to migrate data. The total configuration is user-friendly.

While our current RTO is three hours, Zerto can significantly reduce it to just five minutes.

Zerto helps us significantly reduce downtime during hardware failures, software updates, and natural disasters.

While we haven't experienced a ransomware attack, we have a recovery plan in place. If one were to occur, we could quickly restore production to a previous point in time, minimizing downtime and data loss.

Zerto helps us reduce the amount of disaster recovery testing we need to perform, which also allows us to reduce the number of staff required for the testing down to two.

The Zerto application is licensed per VM. However, the amount of data stored on each VM does not affect the licensing cost. Whether we have terabytes or just a few bytes on each VM, the licensing fee remains the same. This means we only pay for the machines we are replicating, which can lead to significant cost savings.

Real-time replication is a valuable feature, ensuring that changes made to the production site are immediately reflected at the recovery site.

Another feature I appreciate in Zerto is its detailed logging. This functionality allows us to easily access past data and reconstruct the machine's state at any given point in time.

We can recover the replicated machine at the recovery site by simply clicking it back up from the replicated machine. This allows us to keep the original machine running while the recovered machine is active. It's also vendor-agnostic, meaning it works with different hardware vendors like HP or NetApp. In other words, Zerto adapts to the specific hardware we have regardless of the vendor.

Zerto's solution could benefit from additional security features, such as malware scanning tools at the recovery site.

I have been using Zerto for five years.

Zerto is stable.

Zerto is scalable. We just need to add a license and they provide a new key.

The technical support team offers an excellent service. They empower customers by providing comprehensive documentation and guidance, helping them resolve future issues independently.

Positive

The initial deployment was straightforward, and I handled it independently. My only reference was the provided documentation; I required no further assistance.

Zerto's pricing doesn't depend on the number of virtual applications. Even if we have a server with 200 terabytes of data, we'll only pay for protecting that single server, not for the total size of the replicated data. This simplifies our cost structure.

The licensing cost is fair.

I evaluated Veeam and SIM before choosing Zerto. Zerto's interface is much easier to use than the other solutions I tested. Integrating into our environment is also seamless.

I would rate Zerto a ten out of ten.

No maintenance is required.

You can save a lot of time researching solutions by choosing Zerto. It's efficient, easy to deploy, and easy to maintain. Additionally, Zerto offers excellent support, including comprehensive documentation, breach and RCM coverage information, and a knowledgeable customer support team.

We use Zerto for disaster recovery and cloud migration.

The near-synchronous replication is valuable to our organization.

Zerto's immutable data copies three-two-one rule is great.

The ability to block ransomware attacks and help recover our servers is great.

Since we don't have a backup data center, Zerto's cloud disaster recovery is of the utmost importance.

The recovery point objective for our virtual machines is good. We haven't encountered any significant issues. However, there have been some delays due to the substantial volume of data being written to the SQL server.

Migrating data using Zerto is easy.

Our RTO went from three days to a few minutes after implementing Zerto.

In the event of a ransomware attack necessitating data recovery, Zerto would undoubtedly prove invaluable in expediting the process.

Zerto has helped reduce our recovery time from days to minutes.

Zerto has reduced the time our staff spends on data recovery by 25 percent.

The RPO for our SQL server has room for improvement.

On-premises to cloud migration lacks certain features, such as the ability to directly rename virtual machines. In the cloud, renaming resources often requires cumbersome workarounds like cloning and manual renaming.

I have been using Zerto for four years.

Initially, we had stability issues with the older versions but now I would rate the scalability an eight out of ten.

Zerto is scalable.

The level one technical support is slow to respond and we usually need to escalate our issue to get a resolution.

Neutral

We previously used Azure Site Recovery and switched to Zerto because it is more user-friendly with more features.

While the initial deployment presented some challenges and took approximately two weeks to finalize, subsequent deployments have been significantly more streamlined.

In the event of a disaster, we will certainly see a return on investment.

I would rate Zerto an eight out of ten.

Deploying Zerto in the cloud saves us costs on maintaining on-prem hardware.

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

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

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

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

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

We've used the solution to protect virtual machines.

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

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

It's easy to migrate data. 

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

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

It will save us time in a data recovery situation.

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

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

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

I have used the solution for close to six years.

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

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

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

Positive

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

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

We handled the setup with the help of Zerto.

It's hard to quantify the ROI. 

The pricing is pretty fair. It's competitive.

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

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

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

I'd rate the solution nine out of ten.

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