We changed our name from IT Central Station: Here's why

Zerto Valuable Features

Director of IT at Arnott Inc

Our two primary use cases are Zerto's biggest features for us. That's what we use it for. There may be other situations where it can come in handy, but those are our two primary scenarios.

In terms of providing continuous data protection, Zerto has been great so far. Thankfully, we haven't had an event where we have really needed to rely on it, but we have done a couple of tests prior to hurricane season where we disconnect our primary facility. We then go over to our secondary facility where the replicated data is and we bring everything up and then we do remote access to that location to make sure that it's all working properly. It's very capable. I've also done a couple of test scenarios on ransomware reaction where I'll go in and restore a folder, after hours when nobody is in the system, to emulate a situation where we might need to go back and restore kit encrypted files. So far, it's been great.

Regarding the ease of use, there's a web portal that I use to verify that everything is working well. It has a lot of notifications and it emails me if there's anything going on that's out of the ordinary. For example, if the connection to one of my other sites goes down, it will let me know that it's not able to reach that site. I'm very happy with the way the interface works for my needs, and my tech has been pretty happy with it. Our installation is rather small. We only have 14 servers on it. I'm sure there are other companies that have hundreds, but I imagine that they would see the same capabilities. The web portal is pretty well organized and easy to navigate.

The most valuable feature is the speed at which it can instantiate VMs. When I was doing the same thing with Rubrik, if I had 30 VMs on Azure and I wanted to bring them up live, it would take perhaps 24 hours. Having 1,000 VMs to do, it would be very time-consuming. With Zerto, I can bring up almost 1,000 VMs in an hour. This is what I really liked about Zerto, although it can do a lot of other things, as well.

The deduplication capabilities are good.

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

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

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

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

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

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

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

Network Administrator at a educational organization with 201-500 employees

In terms of the most valuable features, having the failover tests where you can see where your actual RTO and RPO would be is really nice, especially for the management level. I really liked the ease of when I need to do a file or folder restore off the cuff. Usually, it takes me less than five minutes to do it, including the mounting of the actual image. That was one thing with Unitrends, it was a similar process but if that backup had aged off of the system, then you had to go to the archive and you find the right disks, load them in, and then actually mount the image. Our main data stores are close to two terabytes. It would take 15 to 20 minutes just to mount the image. Whereas with Zerto, I don't think it's taken longer than a minute or a minute and a half to mount any image that we've needed to go back to a restore point on.

With Unitrends, some could have taken a half-hour. I'm the only network administrator here, so it usually was a multitasking event where we would wait for it to load. I would take care of a few other things and then come back to it.

Switching to Zerto decreased the time it took but did not decrease the number of people involved. It still requires myself and our network engineer to do any failover, back and forth, because of our networking configuration and everything. I know that Zerto allows us to RE-IP machines as we failover. However, because of the way our public DNS works and some of our firewall rules, we have purposely chosen not to do that in an automated fashion. That would still be a manual operation. It would still involve a couple of people from IT.

Zerto does a pretty decent job at providing continuous data protection. The most important thing that I didn't clearly understand upfront, was the concept of journaling and how that differs from traditional backup. For example, if you set journal retention for seven days or whatever, in your traditional backup, it kept that for seven days, regardless of what was happening. You had it versus the journaling, where coupled with some of the size limits and stuff of the journal size, if you don't configure it correctly, you could actually have less data backed up than what you think you do. I also found out that if you have an event such as ransomware, that all of a sudden throws a lot of IOPS at it, and a lot of change rate, that can age out a journal very quickly and then leave you with the inability to restore if that's not set up properly.

We have requirements to keep student data and information for seven years. We need long-term retention for those purposes. We don't typically need to go back further than 30 days for file restores and everything. There has been the occasion where six months later, we need to restore a file because we had somebody leaving the organization or something like that and that folder or whatever wasn't copied over at the time they left.

Zerto has not saved us time in a data recovery situation due to ransomware because we did not have it correctly configured. When we had an event like that, we weren't able to successfully restore from a backup. That has been corrected now. Now that it is configured correctly, I anticipate that it will save us weeks of time. It took almost two weeks to get to a somewhat normal state after our event. We're still recovering somewhat from rebuilding some servers and stuff like that. To get our primary data and programs back up and running to a mostly normal function, took around two weeks.

We also expect that it will reduce the number of staff involved in that type of data recovery situation. We ended up having to hire one of our trusted partners to come in and help us rebuild and remediate. There was at least a dozen staff including our own IT staff, which was another 10 people on top of that. Provided that we do now have this set correctly, it would really drop it down to maybe two or three people.

The file restoration is very helpful. They've improved it over the years to make it a lot more user-friendly and easy to do, which I appreciate. So, we use that quite a bit. The failover process is quite simple and intuitive. Even the configuration and setup are pretty easy to do. It is pretty easy to use. I've done the restoration of servers several times, not as a disaster. When an upgrade on a server goes wrong and it messes things up, I can just fail back to a previous version and try it again. So, that has been really helpful.

It is very easy to use. By using their training materials and their site, it doesn't take long to get up to speed as to how the software works and how to configure it. Once you get into the process, it probably takes just four or five hours to get your sites up on-prem, at least for more simple configurations, and get the data replicating between different VPGs. So, it is very easy, all things considered.

The most valuable features of this solution is the ease of use. In the event of a disaster, you don't need a technical person to actually run the software. You can bring anybody in, with the right instructions and credentials, and they can run the solution.

Having been in disaster situations myself, one of the things that a lot of companies miss is the fact that, during a test, it's all hands on deck, but during a disaster not all those hands are there. I don't know what the statistics are, but it's quite infrequent that you have the ability to get the technical people necessary to do technical stuff. I was also part of the post-9/11 disaster recovery review, and one of the key conversations was about situations where an organization had the solution in place but they didn't have the people. Their solutions were quite complex, whereas with Zerto you can do it with a mouse. You can do it with non-technical staff, as long as you have your documentation in proper order.

I've been doing disaster recovery for 20 years and, in my opinion, the solution's continuous protection is the best on the market. The ability to do the split-write, without any interruption to the production server, and the ability to roll back to any point in time you desire, are two really key features. The back-end technology, the split-write and the appliances, they've got that down very well.

Systems Architect - Cloud at a computer software company with 5,001-10,000 employees

Four years ago when we did a PoC between two other vendors and Zerto, there were two features of Zerto that sold it, hands-down. One was the ease of creating protection groups, the ease with which our engineers could create protection, add virtual machines into the Zerto product, and get them under DR protection. The other products we were looking at required work from two different teams. The storage team had to get involved. With this product, the whole thing could be done by just our virtualization team, and that was a big sell for us.

The second feature that sold us was the sub-second RPO. One of the things that made Zerto's product stand out from some of the more traditional solutions four years ago was its ability to maintain sub-second RPO over a group of machines, and that group of machines could be spread over multiple storage hardware. It was the storage-agnostic features of the product.

CIO at Per Mar Security Services

Personally, what I find valuable is the executive summary that says our DR plan is operational. I can then pass that out to our customers. 

Per Mar has about 75,000 customers and, more and more these days, especially given all this [COVID] pandemic, we're asked: Do you have a business continuity plan? Is it tested regularly? Do you have documentation for it? Two years ago, a simple email from me saying, "Yes, we have this," sufficed. We're finding now that people want true documentation from an independent system that generates a report. The reporting that comes out of Zerto is a lifesaver for me. I'm able to generate that up, send it out to the customers that need it, and say, "Yes. Here are our SLAs. Here is our monthly test routine. Here is where it shows us being successful," and so forth.

We are doing continuous data protection. It works flawlessly. Our recovery points are measured in seconds. We have all these "baby snapshots" throughout the course of the day, so we can roll a VM back to any point in time, spin it up, and away we go. We're actively using that. It works great.

It's easy to use and there isn't a huge learning curve. Even some of the advanced features are very intuitive to folks who have been in this space before. If you have any kind of skill sets around any kind of backup and recovery tool, the user interface for Zerto is very natural.

The near real-time replication is probably the biggest value of this solution. There are some other ways to get that done, but this seemed to be the easiest and cheapest way to get near real-time replication. In most instances, our RPO is about five seconds, which is pretty aggressive and not that taxing to achieve with Zerto.

The ease of use is pretty high. It really isn't very complex to use. They did a good job with the UI, and it is fairly obvious where you need to click, what you need to click, and what you are doing. There are good confirmation screens, so you are not going to accidentally take down or move loads that you are not trying to. It is fairly user-friendly, easy to use, and you don't need to read a manual for three weeks to start using it.

The most valuable feature is the ease of upgrades. We've updated it numerous times since we started, and we can perform upgrades, including with VMware, without impacting anything in conjunction with it.

The reporting on failovers, including the step-by-step and the times, is useful because we can run through a failover and provide reports on it.

I find Zerto extremely easy to use. Setting up VPGs, the upgrade process, failover, and testing are all super easy to do. It is all very straightforward, including the initial setup.

The replication is the most valuable feature. It's almost like a tape recorder. You can rewind if you need to, if something bad happens. You can rewind the tape and your production begins where your tape left off. Where you want it can be replayed for such a purpose.

Zerto is very good at providing continuous data protection. For replication purposes, it's definitely better than Veeam. Veeam doesn't do as good a job as Zerto does when it comes to replication. The other alternative would be to just have backups somewhere. But even with backups, you lose a lot of time because you have to set it all up. With Zerto, you failover, you just click a couple of buttons and you run from the other location.

It's very easy to use. Every morning I go into the dashboard and I can tell the health of the VPG groups. If there's a problem or anything, I'll see it in the active alerts. So the dashboard is pretty simple. There's a status that tells you if the RPOs are falling behind, or from what you set it to, there's a reminder that tells you when to do the failover test. I like that. If I'm going to add a server to a VPG, I just go to the VPG section of the menu, find our group, select it, and then edit it, go to VMs, and there it is. It gives it to me side by side. It tells me what is unprotected on the left, and then this is protected on the right. I can move from unprotected state to protected state or I can remove something that's in a protected state to an unprotected state. It always tells me at the dashboard from the bottom, how many licenses I have, and how many I'm using. I don't go over my license count where I might not be protected. It's pretty easy.

We've never had a situation where we had to go to Zerto for downtime. It's just protection, but we haven't had the situation where we've had to failover. Hopefully, we never do. It's like car insurance. You want car insurance, but you don't want to get into an accident.

Technology Infrastructure Manager at County of Grey

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.

Senior IT Systems Engineer at a manufacturing company with 1,001-5,000 employees

The most valuable feature is DR. In my opinion, there is nothing better at what it does.

The solution provides fantastic continuous data protection. We do a lot of spin up test environments depending on what happened, then make changes and rip it down. Or, if we got hit with malware, then we use that to do a point-in-time recovery. We custom create software in-house, so we will spin up a test environment to test code deployments or do a copy to do the same thing, if we want it to be around longer than a test recovery. For example, somebody got hit with something, then they infected the server. We were able to restore it back to a point in time before the infection. 

It is super easy to use. A non-technical user can get it up in a day. I can get it up in 15 minutes. I've brought it to help desk guys and network operations center guys, and it's easily grasped.

Manager System Administrators at a financial services firm with 51-200 employees

The continuous data protection is very important. Even if it's synchronous, right now we are at seven seconds difference, so we practically have all our data available, always.

Our old solution, Double-Take, required a lot of scripts and they were prone to mistakes. Zerto is so easy to use that when I showed it to my manager, he said jokingly, "Huh. I could use it myself, I don't need you." Zerto is most elegant. When I look at what's going inside Zerto, I see there is a ton of scripting but it's hidden from me. I just need to specify what I want to protect and where I want to protect it; very simple stuff. When they first brought in the solution, I saw what they were doing, how they were running all these commands, but again, I don't need to do any of that. If you do things right and you test it, it will just work with no issues at all. Nobody can come close to the elegance of Zerto.

Manager of Information Services at a energy/utilities company with 51-200 employees

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.

Senior Network Engineer at a legal firm with 1,001-5,000 employees

The most valuable features would be the

  • granular configuration of your SLAs
  • built-in WAN compression as part of the replication 
  • easy wizard-based failover.

The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively.

The replication piece with the built-in WAN compression is important because the network circuit that we send our replication traffic across isn't actually behind our normal WAN accelerators. We were able to use Zerto's built-in WAN acceleration to help those workloads compress.

The failover is important because that way I can delegate initiating a failover to other people without their having to be an expert in this particular product. It's easy enough to cross-train people.

Continuous data protection is Zerto's bread and butter. They do all of their protection through your journaling and that continuous protection gives you countless restore-point opportunities. That's extremely important for me because if one restore point doesn't work, because it is a crash-consistent restore point, you have so many others to choose from so that you really don't have to worry about having an app-consistent backup to recover from.

Zerto is also extremely easy to use, extremely easy to deploy, and extremely easy to update and maintain. The everyday utilization with the interface is very easy to navigate, and the way in which you perform testing and failover is very controlled and easy to understand.

Disaster Recovery Engineer at a tech services company with 501-1,000 employees

One of the most valuable features is the analytics portal. It's still a new feature and has a 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 alerting through there and they're working on it. They actually included us in the study on it. So the actual pre-canned alerting is not very good either. 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 it's down and you don't expect it, but if you know it's coming, you don't want all this stuff 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 15 team members.

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 to another site. 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.

Senior Manager, Technical Services at a logistics company with 5,001-10,000 employees

The most valuable feature is the continuous recovery with the five-second checkpoint interval. Just having those checkpoints prior to when a situation arises, we're able to get the transactional data that occurred right before the server failed. That has been a blessing for us, as we are able to provide a snapshot with no more than five seconds of data loss. This means that we don't have to recreate minutes or hours worth of data for an industry that includes fulfillment, shipping, warehousing, et cetera.

Zerto is very good at providing continuous data protection. It does a very good job keeping up with the system and it creates five-second interval checkpoints. This has been helpful when it comes to needing to fail something over, getting that last moment in time that was in a usable state.

This product is impressively easy to use. It's dummy-proof, once it's set up.

Technical Account Manager at a tech services company with 51-200 employees

The testing features are the most valuable features of this solution. We use the failover test feature not just for testing failovers and disaster recovery, we've also had clients use it for development purposes as well as patching purposes to test patches. We can failover the VM and then we can make any changes we want without affecting production. It's a nice sandbox for that usage.

We also use it for migrations into our data center. We bring in new clients all the time by setting up Zerto in their on-prem and then replicating to wherever their destination will be in our environment.

We've also used Zerto to migrate to the cloud.

Zerto provides continuous data protection. I'd give it a 10 out of 10 as far as that goes. The recovery points are very recent, generally five to 15 seconds of actual production. It's very convenient.

It's also fairly simple to use. Zerto does have some quirks but they have worked those out with recent releases. They're really good about listening to feature requests. We're actually a Zerto partner at our company, so they take our feature requests pretty seriously. Zerto is one of the easiest disaster recovery products I've used. We use Veeam as well which is much more complicated to set up in the back-end.

Senior System Administrator at a financial services firm with 501-1,000 employees

The real-time data protection is the most valuable feature. We are able to quickly spin up VMs instantly. 

We have also utilized it, from time to time, if our backups didn't catch it at night. If something was deleted midday, this solution is nice because you can use Zerto for that. 

I would rate Zerto very high in terms of it providing continuous data protection. We have had multiple instances that took days with our old DR test (before I was at my current company) and DR tests from other companies where I worked that didn't have Zerto. Now, we can realistically do DR tests in less than 30 minutes.

Zerto is extremely easy to use. If 10 is absolutely dummy-proof, I would give the ease of use an eight.

Senior Director - Information Technology at Revenew International

Pretty much all of the features are valuable. The biggest thing we use it for is replication, so the ability to set up our virtual server, set it to replicate, and Zerto handling everything else is the biggest feature that we like.

The continuous data protection is great. We love it because we can see exactly how many seconds behind real-time we are, which is usually under 10 seconds. It keeps things up to date. We love the product.

We currently don't use it for long-term retention. It's something we may look at in the future, but that's not the product we're using for that.

Zerto is very easy to use once everything's set up, which isn't difficult. It takes a little bit of time to make sure all the network stuff is all set up properly, but once everything's set up, using it day to day is very simple.

Zerto has saved us money by enabling us to do DR in the cloud rather than in a physical data center. Our DR is to a physical data center. We don't put our data in the cloud.

The most valuable features are the ease of use, i.e., the relatively low complexity of the solution, as well as the speed and effectiveness of the solution. This allows us to protect our workloads with extremely small latency, making it very easy for us to monitor and recover. So, we are very happy with it.

In terms of Zerto providing continuous data protection, I would rate it as a nine out of 10. It is incredibly effective at what it does. I really have no complaints.

The functionality available in the console is not complicated and is easy to use, especially for DR failover. It just works.

It offers a high level of compression, which is very good. My customers and I are interested in this feature primarily because it saves bandwidth.

The most important feature is that the recovery point (RPO) is less than one minute. This is really good for our customers, as they can keep their data loss to a minimum.

The most valuable feature is the ability to do disaster recovery.

Zerto is very user-friendly and engineer-friendly, as well. When we need to create a new Virtual Protection Group (VPG) for replication, then it is done with just a few clicks of the mouse. We can see all of the environments and we don't need to install agents on the customer's VMs.

The live failover feature is very helpful.

With regards to providing continuous data protection, it's great. Most of the time, it's about five seconds for replication.

The most valuable feature is the disaster recovery capability.

The one-to-many replication functionality is helpful.

Importantly, we were able to do this without affecting the DR setup.

Enterprise Architect at a transportation company with 10,001+ employees

Zerto's support for different hypervisors is a valuable feature because we have a mixed bag. We have VMware and we have Hyper-V. For us, that was extremely critical when we made the decision. We wanted a single tool that is able to replicate all our virtual servers. At this point, I think the only tool on the market that can do that on-premise is Zerto.

It does a great job of continuous data protection. That's why we're using it for DR. It has the journal, the recovery points. It's doing its job. It's a good tool.

It's extremely easy to use with a very intuitive interface. You can set up a VPG (virtual protected group) and add VMs to it in a couple of clicks. Everything is in a single dashboard and you can do everything from there. If you need some granular information, you click the Analytics and get your RPO or RTO and how much data you would lose if you do a DR at this point in time.

The first benefit, right out of the gate, was to duplicate a subset of our production environment and test it in an offline network scenario. That initial test was fantastic as was all of the reporting to prove that we have done those tests. Another big attraction is the near zero RPO. A lot of other products have minutes, half-hour, or an hour RPO. We have proof indicating that Zerto is near zero, or a matter of minutes, as far as the RTO is concerned. So again, that's another attractive offering where you can actually fail something over and bring it back up in a target location in a matter of minutes. Meaning very little data loss as far as recovery time. It's fantastic.

The main reason why we love Zerto is because we have a VMware environment. What we're doing now with VMware is we leverage NSX-T which gives us the ability to have a shared address space across two physical data centers. By using Zerto with an NSX-T, we can failover applications without re-IPing or anything like that. So it's a matter of literally shutting down the forced side and powering up the other side in minutes. It works fantastic and that is definitely our future DR strategy as well as our future failover testing.

Senior Systems Administrator at a comms service provider with 51-200 employees

The fact that it just works is important to us. We don't have to do a whole lot to it. It does its thing in the background and it's ready to go. It enables us to execute our DR plan at any time that is required. It doesn't seem to require a lot of time or management or day-to-day maintenance. 

It doesn't "complain" a lot and it's ready to go at any time, so you could call it easy to use. It's just me responsible for maintaining it, and there is a network infrastructure person involved as well. But it mostly maintains itself, once it has been deployed.

It does what it's purported to do, which is to provide continuous data protection. We have a five-second RPO. It's definitely doing its job. It's there in the background, replicating constantly.

Enterprise Infrastructure Architect at a financial services firm with 201-500 employees

The reliability of the solution and ease of upgrades are most valuable. Support has also been really good on it.

It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing.

It is easy to use once you have gone through the online training class to learn the basics about it. We have been able to get a couple of our folks in the IT department up to speed on how it works and how to utilize it within basically a day or less. It is relatively easy for us to get staff trained and get going.

Zerto's continuous data protection is unmatched. It's phenomenal.

It's also very easy to use. The menus are self-explanatory. Once you understand the terminology of the product, what the VPGs (Virtual Protected Groups) are, you're able to pretty much do what you want in the product. It's very easy to use.

The most valuable feature is the ability to spin up a copy of a virtual machine which is a complete copy, within minutes.

I also enjoy the Analytics, which is something they added recently. They tell me all about my virtual machines and what kind of data we're pushing back and forth. I've been very impressed with Zerto Analytics.

Senior Systems Engineer at a manufacturing company with 1,001-5,000 employees

Being hardware agnostic is nice in that we don't really need a 15 second recovery time. It's easy to use. It's always doing updates behind the scenes. These are the positive things. The setup is pretty easy. Building out the VPGs is pretty easy. And it works like it's supposed to.

Zerto does what it says it will do when it comes to providing continuous data protection. It gives me all my recovery points up to 15 seconds or less. So if need be, we could recover to that point in time that it says it can do.

Zerto is easy to use for the most part. It's pretty simplistic. The UI is pretty simplistic. There are some things that I'm waiting for newer releases to address some functionality that I'm curious to see has been fixed or not in the new version.

System Administrator at City of Rock Hill, SC

We enjoy the simplicity of not only configuring replication but failing over with a single click and then having it automatically reverse replication. We've had other products such as Veeam, and their replication works, however, it's very cumbersome to configure. When you failover, there's a bunch of work you have to do after the fact to reverse the direction and to restore the VM and how it names it and which environment it shows up in.

In terms of continuous data protection, it's the best product that we've found that does this. It's not snapshot-based. It's continuous, so there are no specific points in time we have to worry about recovering to or from. It's pretty much any time, as long as it's within our replication window.

The solution is very easy to use. It's very straightforward. You don't really have to do a lot of reading through the documentation, or things like that. You can basically scroll through the menu and figure it out.

We have not had ransomware, so we haven't had to deal with that, however, we definitely had a disaster recovery issue we had where we had the fail-over site stop unexpectedly. It did save us a bit of data loss, whereas, normally, we would have lost six hours' worth of customer data. In this case, it was seamless. We lost seconds' worth.

The solution has reduced downtime. It has done so a couple of times. There could be some cost savings there. It's just not something we calculate.

The instant recovery at DR locations is the most valuable feature. We're required to do periodic DR tests of critical databases, including Oracle and Microsoft SQL. We have recovery point objectives set for specific databases and we need to be able to achieve them. Zerto helps solve that business problem.

Zerto is also pretty simple and straightforward when it comes to ease of use. There were no big surprises.

Sr. System Administrator at a financial services firm with 501-1,000 employees

The most valuable feature is real-time replication, where we have the ability to recover things in near real-time.

It's very helpful for DR testing because we can recover VMs in an isolated bubble and prove our DR methodology.

Zerto is very easy to use, which is one of its big selling points. It takes just a few clicks to restore a VM, which means that it's easy to train somebody to help in a DR situation.

Systems Administrator at a legal firm with 10,001+ employees

It's a great platform because it's very well built, technically. 

It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster. We use it whenever we can, and especially whenever we are on a tight time schedule for closing a project, or we need to bring information or VMs from a client or from another data center. Zerto is very valuable because of its speed.

And in terms of ease of use, when I started with my current company I didn't even know about Zerto. My first project was a migration from a big customer and I thought, "Wow, this will be a lot of work." It was a little scary because of the pressure to get it done. But Zerto was so easy to use. I like it a lot.

IT Professional at a manufacturing company with 201-500 employees

The real-time replication of data is the most valuable feature. It is a vast improvement in scheduled daily backups. Real-time data is streamed to the offsite data center, which allows us to restore our mission-critical applications up to 10 seconds from when the last changes were made in our system. If we enter a sales order or enter any kind of information in our ERP application it is replicated within 10 seconds to the offsite location. So if we were to have a disaster, it takes about five seconds right now if I look at it. If we were to have a disaster, we would not only have current data, but we'd also be up and running within hours at our offsite data center, rather than days if we had a tape backup solution.

We have begun using it for longterm retention. We also replicate our file server. Our file server has archive or historical data that we have to restore occasionally. And restoring from long term retention is applicable to those types of scenarios, versus the streaming of the data, the real-time data. The longterm retention allows us to restore from further back in time. Real-time is more for recent changes to the data, and the longterm retention is for if we have to restore from further back.

It provides continuous data protection. It has been extremely effective. I've done failover testing, and the data is accurate and current. It works.

In terms of ease of use, Zerto is very intuitive. The graphical user interface of the application, both for monitoring VPG replication, longterm retention success, the configuration of VPG for longterm retention, and the analytics feature is intuitive and allows you to essentially analyze any changes to your environment. All of that requires some training but is not incredibly complex. It's presented in a very easy to use format. 

Zerto dramatically decreases the amount of time it takes to do a failover. I can essentially do it all by myself and I'm one person, I don't really need help. It allows me to restore our environment fully in a matter of seconds, literally. I can do that on my own from my desk very easily and with no outside help.

Solutions Architect / Building Supervisor at a university with 5,001-10,000 employees

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.

The most valuable feature is how simple it is to implement and how quickly you can get up and running at the second site. The solution is also extremely easy to use, for example, You just log onto the console and you can do a test failover with a few clicks. You can run a failover test for your auditors or your management. Afterwards, you can get a report on how easy it was to failover a specific application and the VMs associated with that application.

Sr Director Security Operations at a tech services company with 10,001+ employees

There are two things that are keeping us with the solution:

  1. It does a very good job of keeping the data in sync at all times. 
  2. In the event of a failover or in the event of a contingency, we are able to retrieve the data very quickly without any issues.

Both of these points are valuable to us because we have application data and it means we keep the data in sync. It is very important for us to know exactly where we left off in the event of any disaster or contingency. We can always rely on, or resort to, the data that we have as a backup or a failover. Also, in the event of a contingency, or even for doing a mock contingency exercise, the speed of retrieval of data and the speed of getting back up and running — minimizing the downtime — is important. That's where the second feature comes into play.

Principle Systems Engineer at a government with 10,001+ employees

The most valuable feature is the point in time recovery. This allows us to recover at any point in time, up to a minute or so.

Zerto is pretty user-friendly. Normally, data recovery involves a lot of DBS skills but with Zerto, it is point-and-click.

It is very important to us that Zerto provides both backup and disaster recovery in a single platform. Because of problems that people are facing, we needed to have recovery time objectives (RTO) and recovery point objectives (RPO) for the major cloud providers. This is the primary reason that we were looking for an up-to-date and current solution.

Comparing it to VMware SRM, Zerto is by far the best that I've used before for providing continuous data protection. 

Different parts of the company use VMware, we use Zerto, and then we saw where they were taking us. Ours really takes less than an hour just to do a quick failover. So it didn't make any sense to go with VMware one, so we ended up going with Zerto.

An employee had actually introduced us to it and we looked at it and wanted to try it. He was working for a bank that does quite a bit as far as doing disaster recovery. So if a bank used it then I would definitely use it. 

It is fairly easy. It's not as technical to get around it or anything like that.

It's a fairly easy tool to use.

Cloud Systems Engineer III at a computer software company with 1,001-5,000 employees

The most valuable features are 

  • the single pane of glass
  • the reduction in time it takes for our systems engineering team to manage the platform.

In addition, the RPOs and RTOs are great on it. It keeps up with things. The protection has been perfect so far when we have done our tests of spinning things up every six months or so. All our backups have come up with no issues at all. They just make great replication copies.

Zerto is also easy to use. That single pane of glass makes it very easy to check on the status of replicated items, and if there are any issues, to dig into them to fix them.

The Move feature is the most valuable feature because it allows us to move the VM from our old environment to our new environment with minimal disruption.

It's extremely easy to use. It's pretty self-explanatory as you run through setting up your VPGs for your protection groups and then to do a migration or a test failover.

When it comes to continuous data protection it does the job. With the RTOs and RPOs, it does exactly that. It's the only one that I've seen that you could call a continuous data protection solution.

And one of the most valuable features, something that I wasn't even anticipating, is the file backups. We weren't even considering Zerto to do restores, but it actually is able to do that. Eventually, we could just use this as our backup solution.

It's easy to use. Once I got it installed and going, it was less than a day until I was already confident about using it. I've done numerous upgrades since then without any third-party support.

The return to operations is the most valuable feature because it decreases the amount of time it takes us to recover. 

Zerto is the best of breed when it comes to providing continuous data protection.

It has a number of features rolled together. So when we need to failover, it does it successfully without a lot of stuff that we have to tune underneath the scenes. We use Zerto for the short-term retention of the data.

I would rate its ease of use as an eight out of ten. It has made it a lot easier for us to failover. Usually, in the past, we had to manually go and bring things up and this automates it.

The solution decreases the time it takes and the people we need when we need to fail back or move workloads. It saves around eight hours and one person. We had started off with two to three people.

It could save us time in a data recovery situation due to ransomware or other causes but we haven't used it for that.

We haven't had something where we had to recover data using this product, but I assume it would reduce the number of staff involved in data recovery situations.

It has helped to reduce downtime in testing but we haven't had a serious issue where we had to switch over and use it.

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.

Recovery is the most valuable feature. It has a good DR solution.

Zerto's ability to provide continuous data protection is good. It works. It has continuous availability.

It is pretty easy to use. The interface is intuitive and easy to use. Once you set it up, it just works. So, it is great. 

I like that it's low maintenance; it's set and forget.

As far as replication technology goes, it is a pretty good product.
