Reduced the number of people onsite during a disaster recovery drill
Pros and Cons
  • "Most of the time, this is at least a two person job. We used to have three people doing it. Previously, when we had a disaster recovery drill, the way it worked was 12 of us would show up in the office on a Friday night and work overnight from 12:00 AM on Friday night to 8:00 AM in the morning on Saturday. Then, three of us would be working for four hours out of those eight or nine hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I just stay onsite to help and assist anybody else as they need during that time frame and my work is done in about a 30-minute time frame. This is compared to the four or five hours it used to take for the three of us to do it."
  • "The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't quite give you accurate information inside the plugin to be able to tell us what's going on without having to go into the actual Zerto application and figuring out what's causing the issue."

What is our primary use case?

We do a semiannual disaster recovery test, usually one in January and another in September, where we fail our entire company over to our Arizona DR facility. We run the business out of the Arizona location for the day. In order to be able to do that, the Zerto application allows us to migrate 58 machines over to that location and allows us to run our business from that location for the course of the day.

How has it helped my organization?

We are able to have a successful disaster recovery solution through using Zerto for our Disaster Recovery drills. We are able to fail over anytime, day or night, to run our applications out of our Arizona facility. Within a 15 or 20 minute time frame, we can have those application servers up and running in Arizona. It is just a huge help to have a successful, reliable disaster recovery solution that we know at any point in time, within 15 or 20 minutes, can be running out of a different location.

Most of the time, this is at least a two person job. Previously, when we had a disaster recovery drill it would take two of us working for three or four hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I'm able to finish my work in about 30 mins and be available onsite to help and assist anybody else as needed during the disaster recovery drill. Its ease of use and the ability to have a reliable solution for disaster recovery has become invaluable to us.

What is most valuable?

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.

What needs improvement?

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue.

Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available.

It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution.

Buyer's Guide
Zerto
October 2024
Learn what your peers think about Zerto. Get advice and tips from experienced pros sharing their opinions. Updated: October 2024.
814,763 professionals have used our research since 2012.

For how long have I used the solution?

Almost two years.

What do I think about the stability of the solution?

The stability is rock-solid. Nothing has gone down since we installed it; there has been no downtime.

Typically, once a quarter, we have an update. Last year we were at version 7.5, then we recently went updates to 8.0. On top of that, they release security patches and other things to improve bugs they find in the program. Right now, there is a U4 version that's out, which we will be updating to this quarter.

In the U4 version, there are security enhancements because a lot of zero-day issues that are being found in a lot of the applications. Zerto is making more security modifications and enhancements to the encryption between one location and another, so somebody can't hack your data and access it while it's in transition.

What do I think about the scalability of the solution?

Scalability is very easy. We are going through a POC right now because we want to branch out to the cloud. Just getting that set up and going through the process was about 60 minutes.

It's very scalable and extendable. We can do one to many solutions, as far as where our disaster recovery is going. This is what we wanted. We would never have been able to do that with our SRM product.

There are two engineers trained to use the product. I'm the primary contact for the application and do most of the work on the product. One of the storage guys handles a lot of the storage set up on the back-end with me. We have at least two people trained on each application that we have in-house. Both of us are in charge of making sure the application is up-to-date and doing what it's supposed to be doing. 

How are customer service and support?

Zerto's technical support is very good. They are very reliable and always very pleasant to deal with. We've never an issue working with them. They usually come back with the precise solution to whatever we are troubleshooting.

Our issues are usually user self-inflicted. E.g., we remove a host out of the cluster to upgrade it or do something else with it and don't follow the correct procedure that's needed in order to be able to shut down the Zerto appliance correctly. If somebody doesn't follow that procedure, because they either don't know how, weren't aware of it, or just skip that step, then it causes problems inside of Zerto. This will pause jobs and the VPG will no longer be accessible on that host. Sometimes it's easy to get it back up and running again. Usually, when you put a new piece of hardware in the cluster that has a different set of parameters with its hardware, then the appliance will be missing because it was taken out with the old hardware. Usually, you need to get their technical support involved in order to be able to troubleshoot the issue with them to be able to get the VPG back online again on the new hardware. As I said its self-inflicted most of the time because steps are missed with our processes.

The documentation that we got from them was in depth and work well when needed, if you follow them correctly you will have success. If you don't follow the steps, that's when problems develop. Therefore, it's not a fault in their documentation, it's a fault of the user who's not following the proper steps for success. It doesn't happen often but I think we have contacted technical support only three times in the two years that we've had the product.

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

For eight years prior to using Zerto we used to use a product called SRM, which is part of VMware. We finally switched over to Zerto after having them come in and do a presentation for us. This was after trying for about a year to do that and convince our vice president to allow us to migrate over to a different platform.

The reason why we used SRM was because SRM was built into our VMware vCenter licensing. We never had a successful DR test during the previous couple of years with SRM. By switching over to the Zerto product a year and a half ago, we were able to run a successful disaster recovery test within three months of switching over. We had our first successful disaster recovery tests in two and a half years because Zerto made our life so much easier and helped getting servers over to a new location almost seamlessly. 

In order to be able to have a successful disaster recovery, we need to be able to successfully migrate 58 servers from our Massachusetts location to Arizona. On previous attempts, we got about half the stuff over there, then we'd fail. In other scenarios we would get everything over there but some of the machines wouldn't come up because of the way they were configured. One time, the business was down for about half the morning because it took us that long to get the stuff back up and running using SRM. This was a real pain point for us, getting this product in place and working successfully. It took Zerto to be able to finally get us to do that. It's been a lifesaver. All we had with SRM was nothing but headaches.

How was the initial setup?

The initial setup was very straightforward. We had everything running in half an hour. It got deployed with two virtual machines (ZVMs): One got deployed in Massachusetts and another in our Arizona location. From there, we deploy appliances to each one of the hosts that's inside of the clusters that we are managing for our disaster recovery solution.

Within 30 minutes, we had it deployed to our entire production cluster and the hosts in here. After that, we just started creating jobs, which took quite awhile to do because we have a lot of large servers. However, that's not the worry of the Zerto application, but the size of the VMs we have in production. 

For our implementation strategy, we just mimicked what we had in place for our SRM environment. Our 58 machines are spread across different clusters: some in our DMZ, some in our prod and some in our WebSphere clusters. After that, we ran two tests to ensure that we were able to fail over to our Arizona location then fail back without any changes or modifications to the VMs. Once we did that, we started rolling out to each of the clusters, one Virtual Protection Group (VPG) at a time. I think we now have 23 VPGs total.

What about the implementation team?

We worked with an outside vendor (Daymark) who does a lot of our work through outside vendors. They work with Zerto directly. When we set it up originally, we had a Zerto technician on the call as well as a Daymark technician on-site working with us.

Our experience with Daymark has been very good. We love working with them and try to use them for our integration and infrastructure work. They are a very good company that are easy to deal with. We try to use them as much as we can. Thanks to Rick and Matt for a great working relationship.

What was our ROI?

We have seen huge ROI.

It used to be a three-person job, and now it only takes one person to manage and run the process. The fall back is the same thing. We've never had any issues with stuff coming back out of Arizona to our Massachusetts location. Within 15 to 20 minutes, we can have our servers successfully migrated back, then up and running just as they were originally without having too many conflicts or configuration issues. 

The solution has helped us reduce downtime in any situation that we have come across, thus far, for disaster recovery at a 4:1 ratio.

We are an insurance company therefore, if we're down for an hour, it's thousands of dollars being lost. E.g., people can't pay their insurance bills, open new policies or get the support they need for an accident.

These things have been invaluable to us:

  • Not having to have so many bodies onsite during a disaster recovery drill.
  • Not having to worry about multiple people dealing with the application.
  • The product's reliability of always being up and running and not having any issues with it.

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

It's very equitable, otherwise we wouldn't do it. It's something that we utilize for the licenses per host used. Therefore, it's very cost-efficient as far as the licensing goes. For the amount of stuff that we have configured and what we're utilizing it for, the licensing is not very expensive at all.

There is a one-time cost for maintenance and support. We have a three-year contract that we will have to renew when those three years come up. There is also licensing on top of that for whatever product you are using it depending on the host configurations.

Which other solutions did I evaluate?

Right now, we use Veritas. We will be evaluating Veeam and Rubrik as a new solution for our backups in the next quarter or so, on top of the fact that we may decide to use Zerto. The three of them are in the mix right now for when we decide to switch over vendors for a better backup solution. 

Zerto gives you the ability to utilize it as a backup solution, but it's not a true backup solution because it can't do file level backups. If you want a particular file off of a server, it can't do that for you. What it can do is give you the whole server, then you need to go back and pull that file off it. Mainly for that reason, we haven't chosen to use Zerto and may never use Zerto as our backup solution. The other solutions allow us to get a file level backup.

What other advice do I have?

Don't hesitate. Go out and do it now. Don't wait two years like we did. Push harder in order to be able to get the solution in place, especially since we know it will work better for you. Don't just take, "No," for an answer from senior management.

The application is phenomenal. They continually add new things, more plugins, and modifications to the way things work. It just gets better as they go.

We don't plan to use the solution for long-term retention at this time, but we are looking at going into a hybrid cloud solution in the near future which we may be using long-term retention for to make a duplicate copy of everything we have in our Massachusetts data center into a cloud solution. Whether it be an Azure or Amazon location on the cloud.

While I can't really speak to whether it would allow us to do it, the application is set up to create a duplicate of the actual servers in Arizona. That's how it works so quickly. If we ever had a problem, I could always revert back from the duplicates that we have out in Arizona using the application, if necessary. Luckily, we haven't had a need for that, and hopefully never do.

I would rate this solution as a nine (out of 10).

Competitive price, user-friendly, and continuous data protection
Pros and Cons
  • "The main reasons for adopting Zerto are data protection and being able to do disaster recovery for site recovery."
  • "Patch management can be better. Although we are doing patch management on the Zerto platform in an automated manner, it can be improved by leveraging some AI-assisted technology. With the help of AI, things are going to be faster in terms of patching the solution."

What is our primary use case?

We use Zerto for multiple use cases. We are using it for disaster recovery, backup and recovery, and data protection. There is an inbuilt feature where we can utilize the Zerto platform in a hybrid model which means we have one instance on-premises and another instance on our cloud for redundancy and for cross integration.

How has it helped my organization?

Zerto’s near-synchronous replication works. We have configured near-synchronous replication between two different clusters. One cluster is on-premises, and another cluster is on the cloud. For near-synchronous replication, the value proposition is excellent. We are able to achieve the results for which we procured this solution. Near-synchronous replication is working perfectly. We do not see any challenges with data retrieval, complete replication, and synchronization processes. Everything is working perfectly and seamlessly.

We were able to see its benefits when we integrated it with our HPE GreenLake for DR purposes. It is a SaaS-based platform, so we are able to see the fastest way to recover data and applications. We were perfectly able to meet our recovery point and recovery times objectives through Zerto. On top of that, Zerto is protecting our data from ransomware, cyberattacks, cyber threats, national disasters, or human errors.

We are using a lot of virtual machines on-premises and in the cloud. Our main goal is to protect the complete data that we have in production and non-production clusters with different applications and big platforms.

Zerto is a market leader in continuous data protection technology. Previously, we had RPOs and RTOs in terms of minutes, whereas now, they have changed from minutes to seconds.

Zerto has an inbuilt disaster recovery protection and prevention with continuous replication. Whenever we faced any challenge related to our link being broken or not being able to access the data from the primary data center, all the backups were readily available because Zerto had replicated snapshots. We have not seen much latency or delay in recovery and the ability to get replicated data from different destinations.

We have not had any ransomware type of event. However, during the PoC and testing in an isolated environment, we have seen what would happen in the case of an attack. We could see how Zerto and its policies will take action and isolate that environment within a fraction of a minute or second.

For DR, we were previously using VMware Site Recovery Manager (SRM) but there was a lot of complexity. It was time-consuming. Most of the time, we saw a lot of human errors happening, and we were not able to test our DR activity. By leveraging Zerto for the past 14 or 15 months, we could achieve all of our desired results. There were no human errors. Everything went seamlessly. We are very happy with this solution.

Zerto has had a positive effect on our IT resiliency strategy. With the earlier vendor, we had a lot of problems. Our data got lost in transit during replication, snapshot creation, and recovery scenarios. By using this robust platform, we could achieve our resiliency metrics. The metrics are stable and never went below the benchmark.

Things are working perfectly. Each and every feature is complete with advanced options. It is a simplified DR operation platform. It has great visibility when it comes to protection from ransomware attacks. It has deep analytics features and robust data recovery policies. Everything is good in this platform.

What is most valuable?

The most valuable feature is the resiliency towards cyber threats for data protection. The main reasons for adopting Zerto are data protection and being able to do disaster recovery for site recovery. We can ensure that if the site goes down, data is available to all the users within a fraction of a second. On top of these, we have the resiliency towards malware and other security threats and attacks. Zerto has an embedded feature to protect our data from external and internal threats.

Zerto is very easy to use. It is very user-friendly. It is a GUI-based platform with a centralized dashboard where we can create policies, snapshots, replication policies, and disaster recovery policies. It is very user-friendly.

What needs improvement?

Patch management can be better. Although we are doing patch management on the Zerto platform in an automated manner, it can be improved by leveraging some AI-assisted technology. With the help of AI, things are going to be faster in terms of patching the solution.

For how long have I used the solution?

We have been using Zerto for 14 or 15 months.

What do I think about the stability of the solution?

Since we deployed it, there have been no critical issues or major incidents. The platform is working as per the expectations. There was no downtime of any production activity. We are happy with the stability and overall performance of the complete platform.

What do I think about the scalability of the solution?

It is completely scalable in terms of adding licenses, subscriptions, modules, and different sorts of features. Its scalability is seamless, and it is easy to use.

How are customer service and support?

I have contacted them multiple times. Their support was good. We got a timely response and a timely resolution.

How would you rate customer service and support?

Positive

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

We were using VMware SRM previously. We switched from VMware SRM to Zerto due to complexity, cost, human errors, and data protection.

The most important security feature in Zerto is protection against ransomware attacks and internal or external threats. These capabilities were not present in the VMware platform. Cybersecurity resiliency and protection are embedded in Zerto.

Zerto is very easy to use, operate, and administer. It is very simple and easy to create and work on any of the policies and rules. It is easy to extract reports and navigate to the other tabs where we can see the health scorecard and other things. We can see all the things. It is very easy to patch the entire system. Everything is good.

How was the initial setup?

We have a hybrid deployment. We have one instance of Zerto disaster recovery and protection running in an on-premises data center, and then we have another instance running on the cloud. Both are continuously replicated so that in case of any difficulty or problem with one, we can leverage the functionality of the other one. The on-premises one is taking care of the on-premises environment, and the cloud-based instance is taking care of the cloud-based environment.

Its initial deployment was very easy and flexible. We did not face any challenges. The solution is quite simple. It is easy to navigate, easy to use, and easy to migrate, although we did not go with any sort of migration. It was a fresh greenfield deployment, so we had no issues at all.

Its implementation took us about 12 weeks. It does require maintenance. The maintenance contract was already placed when we went with the purchase order for procurement. It was a multi-year support contract. It does require maintenance in terms of patch management, updates, health checks, performance tuning, policy updates, and recovery plans and procedures updates. We have a storage and backup team working 24/7 in this environment.

What about the implementation team?

We directly worked with a Zerto system integrator. That integrator was recommended by Zerto. We also worked with the Zerto team for the complete architecture, framework design, implementation plan, and other things. We did not take any help from any third-party vendor or resource.

We had five to seven people for its implementation.

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

Its pricing is very competitive. As compared to VMware SRM, Zerto has reduced our OPEX cost by at least 30%.

What other advice do I have?

I would rate Zerto a ten out of ten as a platform. With the help of Zerto, we have very enriched features for ransomware protection of all our data repositories. It provides great support for disaster recovery and response. Our RTOs have improved after adopting the Zerto platform, so everything is good.

Zerto is easy to use and user-friendly. It is not complex, so I find it easy to use. I do not need to have much knowledge about it before using it.

What needs improvement?

Its price should be improved.

For how long have I used the solution?

I have been using Zerto for three years.

What do I think about the stability of the solution?

I have had a crash once or twice.

What do I think about the scalability of the solution?

I feel it is very good because it supports virtual machines.

How are customer service and support?

I have not contacted their support.

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

I have not used any other solution. Zerto is the first one.

How was the initial setup?

It was easy. I have not tried any other product, so I cannot compare it with others. This was my first time using Zerto, and I found it to be easy.

It did not take much of my time. It probably took two to three days, but I am not sure because it has been three years.

What about the implementation team?

I had a little assistance with the deployment. It was not just me. We had three people involved in its deployment.

It needs to be maintained. You need to check whether any user or anything else requires attention.

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

They should adjust the pricing because I feel its price is too much. If they reduce the price, there will be more users and customers.

What other advice do I have?

If you have not deployed it before, you should seek assistance before the deployment.

I would rate Zerto an eight out of ten.

Which deployment model are you using for this solution?

On-premises

It is flexible, stable, and user-friendly
Pros and Cons
  • "Continuous protection is Zerto's most valuable aspect."
  • "Zerto can improve by offering bare metal recovery for our physical infrastructure."

What is our primary use case?

We use Zerto for disaster recovery and cloud migration.

We are an MSP, so we have Zerto deployed on multiple public clouds, private clouds, and on-premises.

We implemented Zerto because its continuous data protection significantly reduces data loss and downtime costs. In the event of a production issue, we can quickly recover using the user-friendly Check Point feature. Zerto also offers flexible support for storage models, primary and disaster recovery, and hypervisors.

How has it helped my organization?

Zerto's user-friendly interface simplifies data protection tasks. It allows users to create virtual protection groups easily, configure failover and recovery processes, and manage licenses.

Zerto's near-synchronous replication can replicate our primary data center services related to PR, which is essential. But somehow, we are facing some pros and cons on this. If we face any challenge like a ransomware attack on our PR site, with the synchronous mode, it is also replicated on DR. That can affect us. So, if we use an asynchronous model, our data will not be replicated continuously from the PR site to the DR site. There is a specific time bracket where the data has been replicated after a particular time frame. So, there are different types of business cases and business requirements. However, we are comfortable with the near-synchronous model.

Zerto helps us set up any disaster recovery site on a cloud-based model and establish an on-premises-to-cloud migration plan. The continuous data protection feature protects our infrastructure services from ransomware and other bugs.

Our virtual protection groups safeguard virtual machines across various models, including hypervisors and virtualized environments. When configured to route to our disaster recovery site after synchronization between sites A and B, VPGs achieve our desired Recovery Time Objective and Recovery Point Objective, meeting our Service Level Agreement. Flexible protection models range from 250MB to 350MB, with varying time slots to facilitate data recovery between the PR and DR sites.

Zerto provides two functionalities: live migration and test failover. Live migration allows a seamless transition of our primary machine to the disaster recovery site within ten minutes.

Zerto has reduced our RTO from 30 seconds to three to nine seconds and has helped reduce downtime.

Zerto has helped save time in a data recovery situation and helped reduce our DR testing.

It has improved our IT resiliency strategy by 90 percent.

The ability to perform disaster recovery in the cloud is helpful because it can reduce our DR footprint and time.

What is most valuable?

Continuous protection is Zerto's most valuable aspect.

What needs improvement?

Zerto can improve by offering bare metal recovery for our physical infrastructure.

For how long have I used the solution?

I have been using Zerto for three years.

What do I think about the stability of the solution?

Zerto is stable.

What do I think about the scalability of the solution?

Zerto is scalable, and if we need to scale down the line, we know it can handle it.

How are customer service and support?

The technical support is good.

How would you rate customer service and support?

Positive

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

We previously used VMware's Site Recovery Manager. We switched to Zerto because it is easier to use and requires less set-up time.

How was the initial setup?

The initial deployment of Zerto is straightforward. We must set up a VM server and install the VR agents, followed by the PR site.

The deployment times vary depending on the business model, but for someone with full knowledge of Zerto, it can be completed within 30 to 90 minutes.

What about the implementation team?

The implementation was completed in-house.

What other advice do I have?

I would rate Zerto ten out of ten, but I would like it to offer bare metal recovery as well.

No maintenance is required for Zerto.

It provides quick insights into where your VMs are and whether they're replicating
Pros and Cons
  • "Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments."
  • "I would like to see some improvements with APIs going into the cloud so that they can more natively orchestrate the migration point-to-point without special hands-on configuration. Azure does some of that natively by having an agent on the VM, but Zerto could improve on its APIs into Azure or Google so that spinning up works more natively in that environment. It would make things smoother."

What is our primary use case?

We use Zerto for disaster recovery as a service and site-to-site migrations. 

How has it helped my organization?

Zerto enables us to do sandboxing failovers. You can run tests on a production environment in a sandbox and spin up a copy of your actual production environment in a few hours. When you're done with it, you can click a couple of buttons, and it's all blown away. You don't need to worry about reverting changes or interfering with your on-prem production environments.

What is most valuable?

The most valuable feature is the overview Zerto gives you, providing quick insights into where your VMs are and whether they're replicating. It's an easy interface to work with. Configuring Zerto to failover in Azure is pretty simple. The biggest challenge is moving from on-prem to the cloud, but that's not an issue with Zerto. The problem is the difference in hypervisors.

What needs improvement?

I would like to see some improvements with APIs going into the cloud so that they can more natively orchestrate the migration point-to-point without special hands-on configuration. Azure does some of that natively by having an agent on the VM, but Zerto could improve on its APIs into Azure or Google so that spinning up works more natively in that environment. It would make things smoother. 

For how long have I used the solution?

I've been using Zerto for about a year now.

What do I think about the stability of the solution?

I haven't faced any stability issues. The only problems I've had have been self-inflicted, so it's pretty good.

What do I think about the scalability of the solution?

Zerto's scalability seems pretty robust. I've had a few larger VMs that have been a little troublesome in terms of the RTO, but they are also outside of best practices. There should be no issues with scalability if you're working within the defined parameters of what's acceptable.

How are customer service and support?

I rate Zerto support nine out of 10. I've used their support pretty extensively. I would say the majority of the experiences have been overwhelmingly positive. Their response times and issue resolutions are satisfactory.  

One thing I would change about Zerto support is the fact that you sometimes can't find the answer you need online. Sometimes, Zerto reaches out with an answer to that particular issue, and it's in a document that the customers can't access without going through support. It doesn't feel like that information should be limited to internal use. I should be able to find that online without going through a support channel. 

How would you rate customer service and support?

Positive

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

I've also used Azure's native Azure Site Recovery solution, and there are definitely some benefits to using Zerto, such as the fact that it works at a hypervisor host level over individual VMs with agents. The performance is probably a little better in most cases. 

Zerto is easier to use than ASR overall, but the setup is a little bit more involved. After the installation, the daily use is pretty simple compared to Azure. With Azure's native solution, there's a lot more that you must do repeatedly throughout the lifecycle of any virtual machine or system that you're trying to protect. Zerto is much simpler in that regard.

How was the initial setup?

The on-prem deployment is super easy and works well. Migrating from on-prem to the cloud involves a lot more steps and things you have to configure so that it can communicate into the cloud and build everything that it needs to. That takes more time. It probably requires twice as much time to deploy on the cloud. 

What was our ROI?

We see the biggest ROI from Zerto's real-time test environment. If we want to do a proof of concept on a hundred servers, we can spin them up within a few hours and have them ready to start testing stuff with real data to see how that might look if we were to deploy that into production. It's an excellent, accurate test environment that we don't need to maintain.

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

Zerto's pricing is competitive, given the benefits and ease of setting it up. It may seem more expensive upfront, but you're going to save that over the long term by spending less engineering time configuring, reconfiguring, etc.

What other advice do I have?

I rate Zerto nine out of ten.

The near-synchronous certification has positively impacted our operations
Pros and Cons
  • "It's very stable. It doesn't require a lot of intervention."
  • "Maybe the reporting for the failover test could be a little better."

What is our primary use case?

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

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

What is most valuable?

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

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

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

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

What needs improvement?

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

For how long have I used the solution?

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

What do I think about the stability of the solution?

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

What do I think about the scalability of the solution?

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

How are customer service and support?

Support has been very good.

How would you rate customer service and support?

Positive

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

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

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

How was the initial setup?

The initial setup was easy.

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

What about the implementation team?

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

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

What was our ROI?

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

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

It could always be less money. 

What other advice do I have?

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

Which deployment model are you using for this solution?

Public Cloud

If public cloud, private cloud, or hybrid cloud, which cloud provider do you use?

Microsoft Azure

Is fast to set up and has valuable replication features
Pros and Cons
  • "It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant."
  • "We would love to have a native management pack for vROps and to be able to view a dashboard and metrics for BPGs within vROps. We would like to have a single view for monitoring and provide customers with dashboards so they can see their own BPGs."

What is our primary use case?

We use Zerto as a DR tool. Instead of having to have a duplicate DR server, we can add a system to BPG and point it to whatever our DR site will be and replicate it for customers.

We also use it for migration planning. If we need to move VMs from on-premise to Azure or back, or it was built in the wrong place, we can easily move it over. 

How has it helped my organization?

It reduced the time for DR tests from the infrastructure side. Being able to get our work done in a matter of a couple of minutes so the app teams can get to work and can do their testing has been significant. 

Before we would have to use a backup recovery tool to restore it to a LAN, which could take hours at times, depending on the solution that was being used. 

What is most valuable?

The replication features are most valuable. It's fast to set up a BPG and get a system added. This aspect is very important to our business. Being able to provide customers with a very fast DR experience, whether it's for a test or live case scenario, and being able to provide the ability to move systems to Azure for cost savings or migrations, saves our ops teams a lot of time.

What needs improvement?

We would love to have a native management pack for vROps and to be able to view a dashboard and metrics for BPGs within vROps. We would like to have a single view for monitoring and provide customers with dashboards so they can see their own BPGs. 

We would also like to have a native plugin for VRA built by either VMware or Zerto. That way there's actual support for it and we're not on the hook for trying to figure out what happened if it breaks.

For how long have I used the solution?

We have been using Zerto for four years.

What do I think about the stability of the solution?

The only problems we've had stability-wise come from upgrades.

What do I think about the scalability of the solution?

This is a scalable solution. The only challenge is that there's no way to manage it centrally at the moment. If you have 30 vCenters, you now have 30 appliances and you have to remember where everything is, which can become a pain point when it comes to trying to find where this VM is being replicated and what BPG it's in. 

How are customer service and support?

The support for this solution could be improved. It is challenging for staff who actually understand the product. We had issues where we ended up spending hours and sometimes days on the phone, only for us to figure it out on our own.

They're very personable and fine to work with. It seems like technical expertise is lacking. I would rate them a five out of ten.

How would you rate customer service and support?

Neutral

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

I haven't used too many other disaster recovery tools. We used standard backup solutions and Zerto is significantly faster. 

What other advice do I have?

I would rate this solution a nine out of ten.
