Zerto Reviews

We are an electric utility and we have some pretty critical workloads. We have identified the most critical workloads in our environment and have implemented Zerto as a protective measure for them.

We try to keep our critical workloads protected, which are a subset of our systems. For example, we're not going to protect a print server with Zerto.

The fact that Zerto provides continuous data protection is key for us. We have tested on a regular basis, and in one case, we tested our entire ERP system. It is a pretty big workload that includes Linux servers, databases, and other components. It's about a 45-minute window to get it back up and running. For our test, we moved the entire system to our DR facility on a weekend, ran it for an entire week from the DR site, and then brought it back the following Sunday. It worked flawlessly.

I really like the 24-hour DVR-like rollback. For example, we had an issue a few years ago, when we still had an Exchange server on-premises. One of my staff came in for the morning to do vulnerability management, saw that some updates needed to be applied, applied the updates to the Exchange server, and it totally broke it. Everybody's email was down. To resolve things, we went to Zerto, rolled back to before the updates, and it was all done in less than five or 10 minutes. It was really quick. All of the email functionality was restored and it popped up and said, "Hey, you need an update." I said, "Please do not do that update." It was pretty good.

Zerto is easy to use and the interface is very intuitive. We have never had an issue with using it. We just have a one-man team to perform failbacks or workloads. It is very simple to do and during our test with the Exchange server, it was only a matter of a few clicks. It's always been an excellent product and they've only improved it over time. We're really pleased with it.

The integration with VMware is really good.

It would be nice if we were able to purchase single licenses for Zerto. As it is now, scaling requires that we purchase a multi-pack. It hasn't been a big deal for us but it would still be helpful to have a little bit more granularity on the license count.

The only timeline or limiting factor, in my opinion, is how long it takes to replicate. That all depends on your infrastructure, and we happen to be pretty fortunate that we have a nice pipe in between the two locations, between here and our DR site. If you don't have that limiting factor, it's just a matter of time. You just wait long enough for it to replicate over and then you're covered.

I have been using Zerto for approximately seven years.

We do the updates regularly and Zerto has never given us problems. We work with a lot of different technologies and we have a lot of problems, but Zerto has not been one of them.

We haven't had much opportunity to explore scalability at this point. We're responsible for another organization's IT, as well. They're a sister company of ours and they're smaller than us, so we do all of their IT and we have them on Zerto. They're using us as a DR point.

From an expansion perspective, we scaled up from our initial install to include theirs as well, which I think we got pretty close to doubling our license count.

We are 100% deployed at this point. If we were ever to add another sister company, which is possible because we have other sister companies where opportunities may arise. A lot of the time, they're so small that they can't afford IT, so it's easier to have us manage it. In cases like this, we may have an opportunity to deploy Zerto.

We have a very small team of three people, so Zerto does not affect our headcount. There is me, who is the manager of IT or manager of information services. Then, we have our desktop technician, and then we have our network administrator.

We have never had to use Zerto's technical support for anything major. Any time that we have had to contact them, it has been for minor stuff and it's worked out fine.

A long time ago, when we had an EMC SAN, there was a VMware plugin that served as a replication solution. However, it was terrible and it never worked.

Zerto is a major upgrade that is easier to use and switching was excellent.

Replacing our legacy solution with Zerto has definitely saved us time and improved the quality of our process. I never felt like I could trust our previous solution, which was a big deal because when you're talking about backups, trust is a major factor. You have to be able to trust your solution and feel like it's going to work in a bad situation.

Zerto is one of those things that you love to have but you hate to have to use because it means that something bad is going on. That said, if there are serious problems then you want to have something that's rock solid. For us, that's Zerto, and we feel strongly about that.

The initial setup was very straightforward. We had some training with some Zerto engineers on how to set up the recovery groups and other things, but once that was set up, we made several changes later on as we played with it. Overall, it was very straightforward to configure and I think that we only had an hour of training.

The deployment took us a couple of weeks to get everything figured out, although it wasn't necessarily Zerto that was the hold-up. We only had a certain number of licenses, perhaps 15 in total. We spent time trying to determine which were our critical workloads, and there was some internal debate about it. From the Zerto perspective, there weren't a lot of issues.

It didn't take a lot of time, just a couple of weeks to get us up and going. We were actually up and technically running within that same day, but to truly boot it and get it where it needed to be, it took a couple of weeks. It was a new technology to us at the time, so it took a while to get up to speed with it.

In terms of our implementation strategy, we just tried to identify the critical workloads, find the ones that really needed to be protected and start to make those recovery groups. Then, we organized them in such a way that things worked properly. For example, the components of our ERP system do have to come up in a certain order. Finding all of that stuff out and fine-tuning the process was part of our strategy. Then, we slowly started moving those workloads across. We broke it down into groups and we did those groups one at a time until the implementation was complete.

Our in-house team was responsible for implementation.

Maintenance-wise, we just keep it updated. Our network administrator applies the updates and checks the health from time to time. We have a dashboard on our big screen if we feel the need to monitor it. If we walk by and it looks like a protection group is in the red or yellow, then we look at what needs to be done to get the problem straightened out.

Price-wise, it's right in line with what we would figure. For what you get for it, it's really a good value, and we've never had any problem renewing it or anything like that.

License-wise, we budgeted $1,000 per VM. The minimum spend on it, in the beginning, can sometimes be a little bit of a headache for people, and they might have to budget creatively to get there, but once you're there, the renewals are worth it.

Licensing requires purchasing packages that consist of several licenses, and they cannot be purchased one at a time.

We paid for an hour of training that we took but otherwise, there have been no costs in addition to the standard licensing fees.

We began looking at Zerto for several reasons including the cost, ease of use, and really, the flexibility of it. When you want to switch it over and do a different workload, it's not that big of a deal.

When we first began to consider using Zerto, we had a discussion with a grocery chain that is close to us. It's a specialty grocery chain and they have exotic foods sold out of two different locations. Christmas is their busiest time of year and they have several cash registers at each location doing transactions constantly.

They had to use Zerto during the middle of that Christmastime rush and failover, from one site to the other, all of their point of sale systems. They never lost a penny in transactions. For us, that was a big testimonial. They have a similar size of environment to ours as far as server infrastructure goes, so we didn't even look at anything else.

At this time, we don't use Zerto for long-term data retention. Instead, we have some other technologies in place for that. We have Veem and we have some SAN replication and we have some network-attached storage, as well. We use Zerto as our first line of defense. For example, in response to a ransomware attack, we would use Zerto for sure to roll back before that event happened.

We have not had a ransomware attack, at least not yet. We fully expect that, if it ever does happen, we'll definitely utilize Zerto. It is essentially our insurance policy. If we ever have a ransomware incident, that would be our first line of defense to recover from it. In fact, we really haven't had many opportunities to use Zerto, thankfully. Zerto is one of those things that are great, and we're glad we have it, but you hope we never have to use it.

At this time, everything we do is on-premises but having DR in the cloud with Zerto is definitely something that we want to do in the future.

It is not important to us that Zerto offers both backup and DR functionality. For backup, we have it covered in other ways. Being in the utility business, we're very big on redundancy. In fact, we have backups to cover the backups and we have about five different levels of them that we utilize. Zerto covers the front line, and when something bad happens, we can roll back within a 24-hour period using it. Then, we have deeper levels handled by other products like Veeam. Funnily enough, Veeam kept telling us that they would add Zerto-like features, and at the same time, Zerto kept telling us that they would add Veeam-like features. We continue to use both of them.

I've recommended Zerto to several IT professionals that I've talked to because it's such a good product. I give them examples of what we have done.

Overall, it's a fantastic product.

I would rate this solution a ten out of ten.

We primarily use Zerto for backing up our databases.

We are heavily invested in database technology. We use SQL databases such as PostgreSQL and MS SQL, and we are also functional with NoSQL databases. Our use cases are majorly relying on databases for financial vendors and most of the time, we have to perform day-to-day operations with respect to finance and accounting.

We have been using the data retention functionality for a long time and whenever there is a failure and the system goes down, we recover the data from that particular snapshot in time.

We also require security, as it is one of the major concerns. Ultimately, we align these two things together.

We are deployed in AWS, although we are also deploying in GCP and plan to do so with Azure as well.

Zerto provides us with continuous data protection that is reliable. It is convenient to use because the API allows for seamless integration when performing our day-to-day operations.

Currently, we do not have any long-term data retention activities, and it is not one of our core operations. However, in the past, we did have several such use cases.

Using this solution saves us time because we have been capturing the volumes and snapshots, are we able to perform operations on the Delta. This is an important benefit to us because we are able to deploy everything into production, then continue to get the backups and snapshots from there. 

Another time-effective benefit is that once we are fully backed up, we are able to perform Lambda functions on our use cases. This saves us a lot of time.

In some instances, Zerto has saved us time and on the number of people involved during failback. The number of people that are involved depends upon how critical the failure is. Any time there is a failure, we have to work from the most recent backups. For example, if the incident happens at 9:00 PM and there is a snapshot that was taken at 8:00 PM, there is one hour of work to make up for. This is much easier and quicker than having to look back at the logs for the entire day.

On a day-to-day basis, using Zerto saves us approximately 20% to 30% in terms of time. Overall, considering both our test and production environments, using Zerto benefits us with an approximate time savings of 60%.

We are using Zerto for DR in the cloud, and it has saved us money over using a physical data center. In a cloud-based deployment, the cost is quite a bit less compared to a physical environment. Also, because the cloud is a pay-as-you-go model, and you don't need the service all of the time, the paid resources are not wasted. I estimate that we save thousands of dollars per year in operations costs.

With our backups fully in place, in the cloud, Zerto has helped us reduce downtime. 

The most valuable features for me are the fast performance and seamless integration. The performance is one of the main features and the integration has helped me a lot.

When we have a system that is being fully replicated, we also get snapshots. Then, we perform our activities on the snapshots only, which reside on the cloud-based volumes. This means that our production environment is not affected.

We have low latency in production because most of the things we do are on the cloud.  When we have the backup, we just start to perform the data operations and with the help of Zerto, we can do this quite efficiently.

Zerto is quite easy to use. With the click of a button, I have been able to use it to do what I need. Furthermore, any end-user that I have worked with has easily been able to make use of its functionality.

Some of the integrations with our internal tools, in particular, company-specific ones, do not work. In cases like this, we have to ask for additional support. This is an area that has room for improvement.

If the API integration worked more efficiently then that would be an improvement.

We have been using Zerto for between two and three years.

Zerto is a stable and reliable product. We have not experienced any anomalies in the tool. For all our use cases and workloads, we rely on it and have found that everything can be done easily.

We have not had problems when we want to redeploy a number of things, so scalability has not been an issue.

We have between 30 and 40 users, including engineers, architects, and management. We are a growing and expanding company, and our workload increased from day to day. I expect that our usage of Zerto and other solutions will increase.

We often reach out to contact technical support and it is good. We have a lot of use cases that we need support for because we don't always have a sufficient solution.

The initial setup was straightforward, although we did have some problems. For example, there were instances where we could not integrate with our internal tools and we were not able to solve the problem. We looked at the FAQ and reached out to customer support to ask what the ideal solution would be.

Overall, it took between six and nine months to deploy.

We deployed Zerto using our in-house team.

We have seen ROI in terms of time savings, as well as other points.

We subscribe to their annual license package and we have tier one support with them. There are no costs in addition to this.

We have evaluated other tools including Veeam and Veritas. There were several factors, including cost, that led us to proceed with Zerto.

My advice for anybody who is implementing this product is to have things properly architected in advance. Otherwise, the implementation will be a hassle. Once the design is complete, if they need to change it then it will be time-consuming.

I would rate this solution a nine out of ten.

We needed Zerto in order to provide a disaster recovery solution for the entire organization. We use it to replicate some resources on-prem and for quick recovery. We also use Azure to replicate for disaster. If we ever have a catastrophic failure or attack at our main headquarters, we could failover and run our resources in Azure. 

We don't use Zerto for backup, we use Veeam. Once the new long-term retention features are added to Zerto, then we will investigate using it for that and possibly dropping Veeam.

There wasn't anything in place that compares to what we're getting from Zerto. Before Zerto, we didn't have a proper disaster recovery program or application in place. We had a simple backup solution where we could back up our data every 24 hours. So we went from that to being able to recover full systems within a matter of minutes. With Zerto, if we do have an event or disaster, we know that we can recover from that much quicker than we were able to before.

We use Veeam Backup for data and not for replication so this is purely just for disaster recovery and replication. We don't use it for data backup, we're still using Veeam for that.

Zerto definitely decreases the time and people it takes when we need to failback or move workloads. The benefit of using it with the Cloud is that we don't have to maintain extra hard work or an extra infrastructure for disaster recovery. With Zerto and Azure, it can all be done essentially by one person. If we're restoring data and systems from the cloud, it can all be controlled from the Zerto interface, whether it's on-premise or in the Cloud. To move the data back, depending on the size of the disaster, if we were to have to rebuild our hardware on-premise, that would obviously require more people. But if it's just a matter of restoring data from the Cloud, it would only need one person. Whereas before, you could probably still do it with one person, but the amount of time that would take would be a lot longer. We would have had to rebuild servers to restore the data. With Zerto, we can restore entire servers from our Cloud repository and have them up and running, it would just be dependent on the speed of the internet. Zerto could easily save us days of time.

It saves us time in data recovery situations due to ransomware. If we had a ransomware attack, we could have our systems available for investigation and run our environment entirely in Azure, separate from our on-prem network. With Zerto as well, we could also recover our systems to the point in time before the ransomware attack happened, ensuring that it doesn't happen again. With our resources in the Cloud, we can scan it for infections and pull it out if it's been lying dormant. The big benefit against ransomware is that we can easily just go back in time to the point before the attack.

The ability to do DR in the Cloud rather than in a physical data center has enabled us to save money. It has saved us quite a bit of money by utilizing Cloud resources, instead of buying a whole new recovery site on-premise. We did an analysis of the buy and one of the reasons why we went with Zerto on Azure is because of the amount of money that we would save over a five-year period. Based on our analysis, it saved us roughly $25,000 a year.

The one-click failover feature is very valuable because of the ease of use as well as the little to no data loss with the constant replication in journaling technologies that it has.

The one-click failover feature is really valuable to us because we need a solution that's easy to use. There's the potential that myself or other staff may not be available at the point of the disaster and it would be possible to have somebody who may not know the technology be able to initiate a failover on our behalf by simply just asking them to click a button.

The important features of having little to no loss of data are extra valuable because if we do have a failover event or an event where we need to initiate a failover for disaster, having no data loss is really important because if we were to have a disaster where we needed to initiate the failover for recovery, and if there was data loss, that's lost time from staff. It's also really hard to tell what data is lost and what has to be made up. We have certain resources here that can't afford any sort of downtime or loss of data.

Its journaling technologies are always sending replicated data up so that we can view what the recovery point objectives would be in real-time. We can see it could be a matter of six seconds to a couple of minutes, and that gives us peace of mind that things are moving constantly so that when we do have a failure, we can go back to pretty much any point in time that we want and have our systems available again.

Zerto is very easy to use, the interface makes it really easy. The wizards that are available, the how-to guides, and the support from Zerto has made it really easy to use. With little to no training, we were able to get it up and running in the test environment in under a day. The interface makes it really easy to use from using it from day to day, setting up new jobs for replications, or even restoring data.

Long-term retention of files is a function that isn't available yet that I'm looking forward to them providing. The long-term retention is the only other thing that I think needs improvement.

We have been using Zerto for around nine months. 

Zerto is very stable, we have not had any issues with it so far.

Scalability is fantastic. It can go from a very small number of machines up to a very large number of machines without any issue. We started small and they included more and more to it and I haven't had any issues. We have not had any problems scaling across sites to other sites within the organization and integrating it all together. It's as advertised that it can be in any environment of any size. It scales very well.

Only one or two people are required for the maintenance of this solution. As the manager of technology and infrastructure, I and the system administrators do the maintenance. I mostly work with it. One of my other staff works with it from time to time, but for the most part, it just does its thing and we don't really need to do a whole lot with it.

Zerto is used extensively in my company in the sense that it is our primary disaster recovery solution. It is used for servers throughout the County for all departments. Every system that we have in place relies on Zerto for DR. As servers increase, we will add those servers to Zerto, for disaster recovery purposes. It's completely integrated into our system.

Zerto hasn't reduced the number of staff involved in overall backup and DR management only because we have a small team to begin with. Our infrastructure team that I'm in charge of is only six staff. So DR and backup is one job amongst many, for all the staff here. The amount of time dedicated hasn't changed a whole lot for us.

Their support is fantastic. Anytime we've had an issue, which has been not too many, they've been very good to resolve any issues.

We also use Veeam and it is really easy to use too. They're both easy programs to use. If anyone can use Veeam, they can use Zerto. I wouldn't say Zerto's any easier or Veeam's any harder. They do different things; Veeam does back up really well. If you need a backup solution, Veeam is far cheaper. Whereas Zerto is fantastic at disaster recovery and replication, but when it comes to backup, that's not really what it's made for. Moving forward that may change. But Zerto is definitely a much costlier program compared to Veeam but it does a lot more.

Zerto itself was straightforward to set up. There was good documentation available and we utilized some of their engineering services to help set up as well. For the size of the products and the complexity that it can do, the actual setup and operations over this are quite easy. It took a couple of days, which included getting everything in Azure set up properly.

The implementation strategy that we did was to create the on-premise environment for a dedicated network, virtual machines, and the installation. Then Azure would become our disaster recovery site in the event that we needed it if we had a disaster on-premise, we could failover all of our services and servers that we needed to in Azure. Then our client computers would connect to them while in the Cloud while be prepared for recovery on-premise.

We utilized a third-party consultant to assist with setting up our Azure environments and Zerto technicians helped us set up Zerto on Azure. Our experience was really good. There were some challenges and there was lots of learning to do, but overall, the experience was good. The staff from Zerto were exceptionally good. They really know the product well, helped quite a bit, and provided instructions and training on how to use it outside of that.

I think that return on investment will come in the event that we do have a disaster that we need to recover from. We have seen some ROI from Zerto by moving virtual machines between data centers, where that has saved us a lot of time. The technology not only is useful for disaster recovery, but also for server maintenance and moving resources between posts and impairments. Before, it could take hours to copy virtual machines, even days. We use Zerto to move resources around with little to no downtime in a lot quicker time. So we were able to save staff time and resources by using Zerto.

It wouldn't have cost us too much with the government. It's hard to equate a lot of downtime to dollars and cents for us because it's more so around staff time and convenience. We have long-term care homes that we need that are up all the time. And any of those maintenance windows we usually schedule after hours. So it's more of an inconvenience for IT staff to work overnight instead of during regular business hours.

Zerto is not cheap; however, it is worth the cost. The licensing model is easy. You buy based on the amount of virtual machines you want to protect and go from there. Even though it is not a cheap program, you do get what you pay for, but overall it became cheaper than maintaining a separate data center.

We looked at Cohesity, Rubrik, and Commvault. Veeam does replication as well, but it doesn't do it nearly as well. We looked at a few other solutions from Dell. We went with Zerto because it had all the disaster recovery functions that we needed, the ability to recover within minutes with minimal to no data loss, and is integrated well with Azure.

I would recommend doing the free proof of concept exercise with Zerto pre-sales engineers and work with them to discuss your environment and then review their recommendations on implementation. From time to time do the free training. I highly recommend doing that. Get your hands on this software and try it out first before doing the production implementation.

The biggest lesson I have learned is that disaster recovery doesn't have to be hard.

I would rate Zerto a ten out of ten. I don't rate many things ten, but Zerto offered me exactly what they're upfront with, what it will do, and it's doing exactly what they said it would do.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

The product can scale. 

We haven't had to engage with technical support. 

I'm familiar with VMware SRM.

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

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

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

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

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

Our customers have witnessed an ROI. 

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

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

We did not use it for immutable data copies.

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

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

I'd rate the solution nine out of ten.

We primarily use Zerto for DR as a service but also for high availability purposes. It's mostly deployed at our on-prem colocation data center. We also do a little on the cloud, as well. 

Zerto makes DR a lot easier. We don't have to spin up copies of VMs or copy applications and databases. Zurto just takes care of all that for us. We just did our annual DR test, and it worked exactly how we expected it to. We're big fans. We like the fact that when you migrate DR, it will automatically be configured for us. For example, it sets the IP addresses because they have different IP ranges and various data centers.

It saves a lot of time during disaster recovery. In our tests, we just hit a button on Zerto, it did its thing, and the solution just let us know when it's done. In the meantime, we could go do other things instead of having to, copy app configs, .ini files, etc.

The near-synchronous replication is great. That's one of the reasons that we went with Zerto. I've had a great experience with it and never had an issue. Having this functionality is critical, especially for DR. If our main data center goes down, we need to flip it and have everything almost identical to what it was when the data center went down. We use it for production high availability, so if that host goes down, Zerto will just automatically forward to the replica that it has on another data store.

The post-configuration part could be improved. For example, it would be super helpful to have the ability to modify DNS. Once the migration is done, we want to do some more modifications to the endpoint.

We have used Zerto for around 10 years.

Zerto is highly stable. We've never had any issues or lost connections between the agents on the VMware host.

Zerto is scalable. We're running it in five different data centers worldwide, and we haven't had any performance issues. It covers 70 hosts across all our data centers.

I rate Zerto support nine out of 10. We haven't had to use support much because it just works. Once we had an issue with a VM that wouldn't upgrade, and they sorted it out for us pretty quickly. I've only used it once, but it wasn't a time-critical situation. If I contacted them during an actual disaster or DR test, then I could see how quickly they can work.

Positive

I've never used anything besides Zerto, but I've done the failover process manually. Zerto just makes it much easier and faster than a manual failover process.

In our DR testing, Zerto allows us to go work on other things while it takes care of everything. That's valuable because we know that we can still hit all of our SLAs in a real disaster. 

Zerto is reasonably priced for the product that you're getting. We keep on buying more licenses, so it's a good price. 

I rate Zerto 10 out of 10.

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.

We purchased Zerto for our business continuity and DR approach to make sure that workloads are available. We have 1,000 servers but are only protecting 250 of them because they are our core servers. The ones we don't currently protect are Tier three applications.

We have had many instances where VMs were corrupted by an application owner, where they were installing something and did not create a snapshot in VMware for it. Instead of tapping into our backups, with just two clicks, we were able to restore the VM back to its original state. It helps a lot in the day-to-day running of our business.

In some instances, there is data within transactions that I need to recover that might be lost. When using Zerto, I might be losing five seconds worth of data instead of losing ten minutes. That helps a lot. Zerto also helped us reduce downtime and we have been able to recover VMs fairly quickly by just clicking two buttons. Within a minute I would have a VM up and running and ready to go with no issues at all.

The RTO and RPO are the most valuable features. I get six-second snapshots for every single time that data gets replicated. I can go back six seconds past whatever happened. The frequency of the snapshots depends on your latency. It could be as frequent as every two seconds.

The overall management plan could improve. If something happens with the VM on the vSphere side, the error codes are pretty weak. If there was a way to click on something within the UI that takes us to a support page or article, that would be very beneficial.

We have been using Zerto for six years. 

This is a stable solution. Most of the time, the issues that we have had with our ZVM going down are caused by us. 

This is a scalable solution. We deployed it in eight different locations. 

The support could be better. Overall they do have the answers for me when I need them but it takes them some time. The Level 1 support team that I contact first when I call in could be more knowledgeable about products and be able to resolve an issue instead of having to wait for a Level 2 or Level 3 person to assist.

I rate their support an eight out of ten. 

Positive

I've seen and looked into the VMware SRM. We also use another company, Cohesity, for our backups. They also have a solution for replication. When comparing these solutions, the RTO and RPO times are fairly reduced when using Zerto to get to a point where we need to be functional right away in an event of disaster recovery.

We have experienced ROI using this solution. It helps a lot when we use Zerto to test out certain applications. It offers a lot of value for our upper management to see how this product helps us in the event of a DR.

The pricing for this solution could be cheaper. They have two licensing tiers. When we purchased it, they didn't have a license for the cloud model. Certain things that I used to get with the basic licensing are no longer available. They are only available in the Cloud. Overall, the licensing model could be simplified. 

I would advise others to test drive the solution themselves. They should play with it, see how it works themselves and try to break it. 

I would rate this solution a nine out of ten. 

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

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

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

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

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

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

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

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

I've been using it for about three years.

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

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

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

Positive

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

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

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

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

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

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

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

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