We were able to migrate from co-lo to on-prem without losing any time
Pros and Cons
  • "Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done."
  • "If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens."

What is our primary use case?

We use it for DR and general backup. We have snapshots or shadow copies with Microsoft and we do Zerto backups to our other locations so we can always get the data back.

How has it helped my organization?

We bought Zerto, in the beginning, to migrate a very important system of the airline from a co-lo that was managed by the co-lo to our on-prem. As an airline, you can't be down because you could cause a ground stop. With Zerto, we were able to migrate all those things across to on-prem without touching anything or losing any time. We took very little downtime.

Also, we've run into some situations where, for some reason, Windows has lost some of the files. I have been able to fail it over to our other data center and they were back up in 10 minutes.

The speed of recovery with Zerto versus other disaster recovery solutions is vastly better. Whereas with the others, I'd have to spin through a lot of stuff and find things, with Zerto I can scroll back in the GUI, find the one I want, and restore it. If that's not right, I can destroy it and go back a little bit more in time.

And our being an ultra-low-cost airline, we don't have staff, so it helps in that way.

It has also helped our DR testing because we can fail over the main part that runs the airline within 45 minutes. The first time, it took me an hour and a half. The second time, it took about an hour. The last time I did it, it took about 45 minutes. That's within the timeframe of one hour where we don't have to do a ground stop.

What is most valuable?

Moving the VPGs from one location to another is a valuable feature. You just click on it and move it and it's done. We have a stretch VLAN between our data centers so it's really easy: this is IP here and the same IP is there. So if something happens or somebody wants to test something, I can fail it over.

Another aspect that I use a lot is that I can fail it over into its own little bubble and I can install software that I want to test to make sure it doesn't break something. I can do that and then roll it all back.

What needs improvement?

If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens. 

The other thing that I've run into lately is that when I've done a whole bunch of upgrades to systems, so they're offline, they get stuck in a pending state. You can never get them out so you have to delete and start all over again. It would be nice if they could make it a little simpler to figure out what's wrong.

756,650 professionals have used our research since 2012.

For how long have I used the solution?

I have been using Zerto for about six years.

What do I think about the stability of the solution?

It always just runs. I don't have to worry about it or keep checking it. It just does its thing.

What do I think about the scalability of the solution?

It's very scalable. Fortunately, we bought a bunch of licenses when we first bought it and we've been growing into those licenses over the years. It has been very scalable for us.

How are customer service and support?

The technical support has been good, although I've had a couple of situations where they've said some things that were totally inaccurate. But you have that in all organizations.

How would you rate customer service and support?

Positive

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

Since I started with this airline, we have gone through two other solutions. Zerto is the third and we've stuck with it for quite a few years.

One of the other solutions was a direct product that dumped everything to a storage area in the cloud and it never was consistent. The other was a Dell application backup that no longer exists. That was just too limiting and its backup was never consistent.

Zerto is much easier to use. Once you get the concept down of what it's doing, it's really easy to bring up backups, restore backups, move things around, and test things. It's very easy.

What about the implementation team?

I had one of their sales reps in Colorado help me through the setup. Then we just took it over.

What was our ROI?

The ROI is in "funny money." It's my time and how long something is down or how long it takes somebody to restore something, and that is much faster.

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

The pricing seems really good. We're an enterprise customer, so we get all the bells and whistles.

Which other solutions did I evaluate?

We evaluated a couple of things, but one of our co-los was actually using Zerto so we looked at it as a result. That is what led us to buy it.

Helped our organization by merging many different technologies into one, including desktop virtualization and replication
Pros and Cons
  • "The most valuable tool is the dashboard, which allows us to immediately check the DLP status, replication data, and all other data needed to have cleaner and immediate control of the situation."
  • "The technical support has room for improvement."

What is our primary use case?

Currently, we use Zerto to replicate our production visual systems at our disaster recovery site in Germany. This allows us to easily meet our RTO and RPO.

How has it helped my organization?

Zerto is easy to use. Zerto is the leading disaster recovery solution.

Zerto's synchronous replication is important for our organization.

Zerto has helped our organization by merging many different technologies into one, including desktop virtualization and replication. Previously, we used to hire other providers for these services, but now we have everything in one system, saving us around 30 percent. For example, we used to have to keep a copy of our data on Veeam Backup, but now we can store it all in Zerto. This saved us time and money, and it has also made our IT infrastructure more reliable.

With Zerto, we are meeting our RPO better. Previously, it took us 20 minutes and now it is five seconds. 

With Zerto, we have the best RTO.

In our simulations, we observed a reduction in downtime when using Zerto.

Our recovery time with Zerto is excellent in data recovery situations, such as those caused by ransomware. We can save around five hours compared to other solutions.

Zerto reduced the number of people involved in our data recovery by 30 percent.

What is most valuable?

The most valuable tool is the dashboard, which allows us to immediately check the DLP status, replication data, and all other data needed to have cleaner and immediate control of the situation.

What needs improvement?

File management can be improved. Zimbra is the only platform that allows for file replication.

The technical support has room for improvement.

For how long have I used the solution?

I have been using Zerto for five years.

What do I think about the stability of the solution?

Zerto is a stable solution.

What do I think about the scalability of the solution?

Zerto is scalable. We have around 200 users.

How are customer service and support?

The technical support is average. We have had some cases where we were not as comfortable with the outcomes as we were with other solutions.

How would you rate customer service and support?

Neutral

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

We previously used a custom solution, but we switched to Zerto to unify our systems and improve visibility.

How was the initial setup?

The initial setup was simple. We were able to deploy one FPE every two weeks. One person was involved in the deployment.

What about the implementation team?

The implementation was completed in-house.

What was our ROI?

We have seen a return on investment with Zerto, which saved us 30 percent of our costs and improved our disaster recovery time.

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

The price is reasonable.

Which other solutions did I evaluate?

We did not evaluate other solutions because we were confident that Zerto was the best, as indicated by the Gartner chart.

What other advice do I have?

I give Zerto an eight out of ten.

Zerto is deployed to replicate our on-premises and virtual infrastructure data between our two offices in Germany and Italy.

Zerto requires around two hours per month of maintenance.

I recommend that new users take advantage of Zerto's flexible license program to buy one or two licenses and try them out before fully committing.

Which deployment model are you using for this solution?

Fast replication and recovery, and the mobile app is great
Pros and Cons
  • "The ability to perform DR testing to ensure data integrity is critical."
  • "Increased granularity in how long to keep the journal would be nice."

What is our primary use case?

We primarily use this solution for disaster recovery. The initial sync was from Pure to Compellent, and DR with disparate storage was great. Once we identified our critical servers, vetted the Live and Test Failover, and got the necessary configuration at our DR site, we are now able to perform tests in a safe bubble.

How has it helped my organization?

This solution is an integral part of our DR plan. The data and servers we needed are protected in a group as I need them. Changing or adding servers is easy and fast. The ability to protect resources that are in hurricane zones has been fantastic. Being able to safely perform DR testing remotely has enabled us to meet DR goals that were put in place. The first DR test with everyone in a room was fun, as everyone who hadn't seen it was amazed at how fast a server can come online.

What is most valuable?

The replication has been outstanding, it was three times as fast as initial Compellent replication. The ability to copy new data and protect new servers without a significant delay in getting the data is very valuable.

The ability to perform DR testing to ensure data integrity is critical.

The mobile app is great.

What needs improvement?

Increased granularity in how long to keep the journal would be nice, currently you can only do hourly up to 1 day, after that it is only daily.  The ability to test failover for a single VM in a VPG would be beneficial for testing purposes.  Currently alerts come from both replication managers at times, creating a lot of alerts; reducing those would be good.


For how long have I used the solution?

We have been using this solution for just under two years.

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

We did not use another solution prior to this one.

How was the initial setup?

Setup is really easy and quick. Make sure that you have your desired networking for replication and testing in place.

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

You are getting what you pay for, as this is a solution that requires minimal management after it is configured.

Which other solutions did I evaluate?

We did not evaluate other options that are worth noting.

EMC was too expensive and everything else was tied to the storage vendor.

What other advice do I have?

It has been a great purchase, and we have no regrets.

Not much can be improved in this solution as it has performed to what we had hoped and has the features we currently desire.

Simplifies our multi-target replication from remote locations that lack redundancy
Pros and Cons
  • "We use to use VMware replication appliances to attempt to replicate our VMs to remote locations and servers, but Zerto's one-to-many replication options with deduplication have made the process much simpler without having to constantly worry about the versions of each driver."
  • "The number one thing we have found we would like changed so far is the cost per VM. It would be great to get that pricing reduced."

What is our primary use case?

We use Zerto at our remote locations as a backup solution in environments where we don't have the infrastructure for redundancy. It allows us to use two HPE DL380 servers as stand-alone VMware hosts and replicate the VMs without needing shared storage.

How has it helped my organization?

Using Zerto, we are able to replicate / backup our VMs and between servers and locations, without the need for shared storage, which provides redundancy in case of hardware failure.  We are able to fail the VMs over to the secondary host, which also allows us to patch or repair hardware without extended downtime. 

What is most valuable?

We use to use VMware replication appliances to attempt to replicate our VMs to remote locations and servers, but Zerto's one-to-many replication options with deduplication have made the process much simpler without having to constantly worry about the versions of each driver.

What needs improvement?

The number one thing we have found we would like changed so far is the cost per VM. It would be great to get that pricing reduced.

The need for a VM to be spun up on every host is challenging. In our remote locations, it's not a big issue, but as we look to use that in our main data center where we have hundreds of hosts, it becomes more daunting.

For how long have I used the solution?

I have been using this solution for six months.

What do I think about the stability of the solution?

In the six months that we have used it, we have not had any issues.

What do I think about the scalability of the solution?

So far, it looks like it should scale to our entire environment of over three thousand VMs.

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

Prior to this solution, we use to use SRM. We were looking to switch because SRM continues to be troublesome and requires a select combination of drivers and versions across the environment to work correctly.

How was the initial setup?

This initial setup was pretty straightforward with the exception of needing a VM on every single host.

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

The cost per VM is a bit high.

Which other solutions did I evaluate?

We also looked at RapidDR from HPE but it only works on our HPE SimpliVity servers and not across all of our hardware.

Which deployment model are you using for this solution?

Helps predict future storage needs by tracking trends in space, journal size, and I/O rate
Pros and Cons
  • "The mobile application is very useful as a real-time monitoring, reporting tool. When asked the status of our machine backup and recovery ability, an easy answer is to display the status on the real-time application or browser. The Zerto Analytics tool helps predict future storage needs by tracking trends in space, journal size, and I/O rate. These are reportable statistics making quantifiable tracking easy and accurate. Having a web interface simplifies access by other system administrators."
  • "Certain areas were designed and work fine for VMware but are under development for Hyper-V. Eventually, all features will work for both platforms."

What is our primary use case?

We use Zerto for replication to a DR site of Windows and Unix machines. We like having a testable solution which does not interfere with the performance on our production machines. It has an included feature allowing assignment of a specific LAN or IP address to segregate the machine while testing. We are replicating 56 machines, totaling more than 30 TB, but compressing at 70 percent for space savings. We use the email alerts as a way to monitor replication status. This helps in off hours alerting for potential problems.

How has it helped my organization?

Testing and auditing are required at our organization. Zerto has saved a tremendous amount of time in performing these tasks. I am alerted every six months to retest each protection group. This setting is customizable. All past testing reports are retained and available upon demand. It has also added assurance in recovering servers and/or files. Being able to run tests on a working machine is beneficial. Being able to group virtual machines in order to recover all of them to an exact point in time is a definite benefit.

What is most valuable?

The mobile application is very useful as a real-time monitoring and reporting tool. When management asks the status of our VM backup and recovery, an easy way to answer is to display the status on the real-time Zerto application on a mobile phone or on a local computer browser.

The Zerto Analytics tool helps predict future storage needs by tracking trends in space, journal size, and I/O rate. These are reportable statistics making quantifiable tracking easy and accurate. It is nice the see developing trends. 

Having a web interface simplifies access by other system administrators.

What needs improvement?

Certain areas were designed and work fine for VMware but are under development for Hyper-V. Eventually, all features will work for both platforms. Zerto support is very responsive when those questions arise. 

There is a comprehensive online training program which is a good start to using the application. But nothing can take the place of actually using the product in your own environment. 

The online search for solutions is very large. This is good, but also bad, as there are solutions present but you have to be diligent to find the answer you need.

For how long have I used the solution?

I have been using this solution for more than three years. My organization utilizes Hyper-V instead of VMware. One big advantage of Zerto is its hardware agnostic. I have used various models of arrays and servers from Dell EMC and HPE with no issues from Zerto.

What do I think about the stability of the solution?

It picks up nicely where it leaves off (in the case of a reboot).

What do I think about the scalability of the solution?

It easily grows at whatever pace is needed.

How are customer service and technical support?

In the few cases that I have had, every one was dealt with quickly and by support staff who knew what they were doing.

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

We still use our previous solution because it creates a backup of both physical and virtual machines. However, there was an impact on performance running a backup on a running machine.

How was the initial setup?

There is a slight learning curve when setting up, but nothing overwhelming for a good administrator.

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

Work with your local representative on running a live test to see if the solution fulfills your needs.

Which deployment model are you using for this solution?

Has good documentation, is easy to use, and is stable
Pros and Cons
  • "The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen."
  • "For special situations, there are options within advanced settings. You don't have to dig too far for them, but they're not quite as straightforward."

What is our primary use case?

We use Zerto for offsite replication.

What is most valuable?

I like how easy it is to run our DR tests with it.

In terms of ease of use, in the user interface it's very easy to tell the different virtual protection groups apart. It's easy to figure out where your virtual machines are and set different recovery IPs. It is a lot easier with Zerto than it was previously.

When you compare Zerto's ease of use versus that of the previous solution we used, Zerto has good documentation. That's probably what made it the easiest to install and configure, and have peace of mind that it's going to do what I expect it to do.

Every six months when I go through my audit, I don't have any stress about whether I'm going to pass any of my audit logs or any of the questions the auditors ask me. That is, I know I'm going to pass.

Zerto helped us reduce downtime.

Our disaster recovery test used to take quite a long time before we started to use Zerto. After we started using Zerto, the speed of the virtual machines' backup when they are going into test mode, is just so much quicker and so much more consistent. When we previously performed tests, we would need a block of about a week. Now, it's two days. The actual recovery portion is just a small part of that, but Zerto cut it in half easily.

For how long have I used the solution?

I've been working with Zerto since 2019.

What do I think about the stability of the solution?

The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen.

What do I think about the scalability of the solution?

We're a very small shop, but when we did expand to another group of servers that we were going to replicate, it was very easy to go in and just add another virtual protection group, add my virtual machines to it, and set my settings up and go.

We have less than a hundred virtual machines that we replicate.

How are customer service and support?

The technical support staff I've had to interact with have certainly been some of the better ones. I feel that their turnaround time is always pretty fast and that you get reasonable support right off the bat. If my problem is a little more technical, then I may be transferred, but I don't find that to be an issue. I would rate technical support at nine on a scale from one to ten.

How would you rate customer service and support?

Positive

How was the initial setup?

The initial setup was pretty straightforward for the site-to-site recovery or for setting up the VPGs. If you just want to do basic replication and you don't have a lot of special situations to account for, you could have it up and running very quickly.

For special situations, there are options within advanced settings. You don't have to dig too far for them, but they're not quite as straightforward.

What about the implementation team?

We implemented it ourselves after reading through Zerto's best practices, etc.

What other advice do I have?

If you want something that you can set and forget, Zerto is a solution you should look into. If I were to rate Zerto on a scale from one to ten, I'd give it a nine.

Reduces our DR testing, and fast and simple to use
Pros and Cons
  • "Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration."
  • "If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process."

What is our primary use case?

We are mainly using it for DR and, in a few use cases, we leverage it for migration as well. It really fits our use cases.

How has it helped my organization?

The experience has been smooth when it comes to DR testing, as it has reduced the testing we need to do. 

What is most valuable?

Some of the most valuable features are the synchronous replication and migration with RDMs. I really like the conversion of RDM VMs for migration. It is very simple to use and fast. We haven't run into any issues.

What needs improvement?

If we have multiple VMs in a VPG (Virtual Protected Group) and one VM is hung for DR, it holds things up. The only alternative is to create multiple VPGs. It would be nice to have one VPG where, if one VM is failing, it does not impact the overall process.

For how long have I used the solution?

We have been using Zerto for close to a year.

Our experience with Zerto has been good, but I don't know if we have actually saved a ton of time with it. There have been no issues or real challenges so far. We just recently adopted and started using it, so in terms of implementation of real use cases, it has barely been a couple of months. We haven't even done a single upgrade of it yet.

What do I think about the stability of the solution?

The stability is good.

What do I think about the scalability of the solution?

We right-sized initially and we have not had to scale up yet.

How are customer service and support?

I haven't had to engage support. One of my colleagues handles that. But I have heard no complaints about support.

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

We have a VMware product, SRM, and we use it in a few data centers around the globe. We started using Zerto in a few locations and, in other locations, we still have other products being used.

We were using SRM in our data centers and what happened was that we had a merger. In that process, the other party already owned some Zerto licenses. That's when we got our hands on it and started looking at it. We figured Zerto would be a better fit for our European data centers. We ended up using Zerto there and then got more licenses so that we could use Zerto more.

Which other solutions did I evaluate?

We have one other solution that we use for live migrations, VMware HCX, rather than Zerto. But we were not always able to use that. That's where the delta for those VMs is, and why we use Zerto for migrations.

The speed of recovery of Zerto is right up there compared with other solutions. It's good, no complaints in that respect.

Compared to other solutions, Zerto is very straightforward and simple to use. The preparation for DR is fairly straightforward, and the deployment is not very complicated.

What other advice do I have?

Zerto hasn't cut the number of staff involved in data recovery, for us. We had one engineer doing it before and he continues to do it. He wears multiple hats. You cannot go down to less than one engineer.

Is easy to setup and use, but technical support and customer service need improvement
Pros and Cons
  • "I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute."
  • "Customer service and technical support need improvement."

What is our primary use case?

We use it mainly to move the server alarm between vCenter and the physical center.

What is most valuable?

I like that Zerto is easy to move and that there is no effect on the user. That is, the user doesn't even know it. We're in the healthcare industry and work for a hospital. We can set up a server in no time whatsoever. It's easy for us to schedule the time because it takes only about one minute.

In terms of ease of use, Zerto is a lot easier to use in comparison to similar solutions.

We have had no downtime with Zerto.

The speed of our upgrade is a lot easier because, for example, when I put the move fail and there's a pullout from the destination, I can cover with something from the source and pick it up from the source in person. I can copy the tag from the server very fast.

What needs improvement?

Customer service and technical support need improvement.

For how long have I used the solution?

I've been using it for about five years.

How are customer service and support?

Customer service and technical support need improvement, and I would rate technical support a seven out of ten.

How would you rate customer service and support?

Neutral

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

We switched to Zerto because it is easier to use, and the users did not complain.

How was the initial setup?

The initial setup was straightforward. You open the firewall, install it, connect to vCenter, and then do all the steps to install the software.

What other advice do I have?

On a scale from one to ten, I would rate Zerto a seven because of the bad experience I had with technical support.
