I would not do a virtual based disaster recovery solution without this tool
What is our primary use case?
How has it helped my organization?
Would not do a virtual based disaster recovery solution without it. Or would not do a virtual to virtual migration without it.
What is most valuable?
It just works. This sounds simple, but it is so true. So much of what we are sold in IT doesn't work as advertised. Zerto does.
What needs improvement?
It's coming, but I want to do my backups from my DR side without impacting my production side. This is supposed to come out in v7.0.

842,690 professionals have used our research since 2012.
For how long have I used the solution?
Three to five years.
What do I think about the stability of the solution?
Rock solid, it just works. Make sure your Windows boxes are not previous in-place upgrades. Bugs between the Windows components create issues with assigning IP addresses. This is a Microsoft issue and not a Zerto issue.
What do I think about the scalability of the solution?
It's being used for hundreds of machines. It just works.
How are customer service and support?
Tech support is great. They help troubleshoot things that are not their issues. See Microsoft upgrade note above.
Which solution did I use previously and why did I switch?
Yes, VMWare Site Recovery Manager. SRM is not as intuitive and is VMware version dependent. Zerto does not have those issues.
How was the initial setup?
Very easy setup. Like all DR solutions, it requires planning. Specifically the network side. Don't skimp.
What about the implementation team?
Use a Zerto cloud service provider. They generally know their stuff.
What was our ROI?
Amazing ROI considering I don't have to buy a second set of hardware for my DR site. I can use a cloud provider and only pay when I need it.
What's my experience with pricing, setup cost, and licensing?
Check your cloud providers. You don't have to host the DR side yourself. Also, look at folks other than Azure and AWS. The hidden/surprise costs will knock your socks off.
Which other solutions did I evaluate?
Veeam (no CDP), SRM, RecoverPoint for VMs, Double-Take.
What other advice do I have?
No.

Network Administrator at a financial services firm
Can quickly recover from any disaster with very little downtime utilizing a user interface that requires minimal experience
Pros and Cons
- "The ability to test which virtual machines can be failed over to our DR site without interruption of our production environment."
- "The only issue that I observed was that depending on the number of virtual machines that are being replicated, you will have to provision the appropriate bandwidth for the link that the replicated systems will traverse."
What is our primary use case?
Zerto is used to provide real-time replication for the important virtual machines that my organisation uses to our Disaster Recovery (DR) site to ensure business continuity.
What is most valuable?
The ability to test which virtual machines can be failed over to our DR site without interruption of our production environment. Being able to do file level recovery in case you delete a file accidentally or want to recover from a ransomware attack.
How has it helped my organization?
It allows for my organization to quickly recover from any disaster with very little downtime utilizing a user interface that requires minimal knowledge or experience.
What needs improvement?
I cannot think of any new features that should be added at the moment. With time, I should be able to make suggestions.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
None whatsoever.
What do I think about the scalability of the solution?
The only issue that I observed was that depending on the number of virtual machines that are being replicated, you will have to provision the appropriate bandwidth for the link that the replicated systems will traverse. Zerto gives you a bandwidth calculation estimate, but in my case that still was not enough to handle the volume of traffic being generated by our virtual machines.
How are customer service and technical support?
10 out of 10.
Which solution did I use previously and why did I switch?
We used to use Veeam Backup and Replication. We encountered some loss of connectivity with Veeam when we replicated some of our larger virtual machines that we hosted on our older virtual machine hosts.
How was the initial setup?
It was straightforward and easy to setup. Once the software was executed, all that was needed was the basic environment details as well as the hypervisor information.
What about the implementation team?
We implemented through a vendor team. They were very experienced and were able to provide detailed answers to all of our questions.
What was our ROI?
We expect to achieve a ROI within four years of the purchase. However, the ability to almost instantly failover and the fast file level ransomware recovering times give you that peace of mind that allows for low stress levels.
What's my experience with pricing, setup cost, and licensing?
The setup will require that you have a domain controller and DNS at your DR site as well as a second hypervisor product (VMware vCenter Server/Microsoft Hyper-V) there as well. So, the additional software licensing will have to be factored into your operational budget.
Which other solutions did I evaluate?
No, we did not. When we did our research, Zerto was the name that always came out as the market leader.

Head of Cloud Architecture at a comms service provider with 51-200 employees
Top of the list if you're using VMware or Hyper-V. Would be nice to have more supported hyper-visors.
What is most valuable?
Near real time continuous disaster recovery, Journaling and the ability to replicate from Hyper-V and other VMware clouds into our cloud.
How has it helped my organization?
We provide this product as a service to our clients. The ease of providing test failover results to them is invaluable and only takes a few minutes to initiate and complete so no time is wasted.
What needs improvement?
More Supported Hyper-visors
For how long have I used the solution?
2 year
What was my experience with deployment of the solution?
Non What so ever very straight forward and easy to complete. Also upgrading to the latest version could not be easier to do.
What do I think about the stability of the solution?
Not once in the last two years.
What do I think about the scalability of the solution?
Non scales easily with an appliance on each ESX host and a central management console.
How are customer service and technical support?
Customer Service:
Excellent
Technical Support:Excellent
Which solution did I use previously and why did I switch?
We did use a previous product which was clunky to use and was only a point in time image. Zerto is simple fast and reliable and our clients like the charts we can produce and is near real time.
How was the initial setup?
Initial install was straightforward and simple to complete with the minimum amount of time taken up.
What about the implementation team?
We had Zerto help us with the implementation and they were brilliant.
What's my experience with pricing, setup cost, and licensing?
We pay per month per protected VM which is vastly cost efficient.
Which other solutions did I evaluate?
Yes, I looked at VMare SRM and Veeam Replication.
What other advice do I have?
If you are looking at DR products put Zerto straight to the top of the list if you are using VMware or Hyper-V.

Leader in Advanced Services department at a tech services company
Some of the valuable features are journal, consistency groups, and resiliency
Pros and Cons
- "Consistency Groups: If you replicate groups of VMs, then during failover, all of the VMs in groups are failed over to the exact same point in time."
- "I would like to see a couple of details regarding awareness of VM events coming outside of ZVR."
What is most valuable?
- Journal: ZVR uses a journal of history changes. Whenever you need to failover a VM or group of VMs, you have the ability to choose a Point in Time to which those replicas should be switched. For instance, if a disaster occurs at 10:05:00, you can failover with replicas to 10:04:55.
- Consistency Groups: If you replicate groups of VMs, then during failover, all of the VMs in groups are failed over to the exact same point in time.
- Resiliency: ZVR is resilient to Zerto infrastructure component restarts and loss of connection between sites which are automatically handled. The ZVR is very lightweight it doesn't use snapshots and has close to zero impact on production VMs and many others. It lets you get your files from Windows based VMs without failing over to replica VMs.
How has it helped my organization?
Before ZVR, we had many limitations in case of protecting production VMs during working hours. This primarily came from frequent VM snapshots impacting users. ZVR lets us protect our VMs without any impact upon users and greatly improved our RPOs from hours to seconds.
What needs improvement?
I would like to see a couple of details regarding awareness of VM events coming outside of ZVR. This could be a user reverting VM back to an older snapshot, which can sometimes screw up the replica, but nothing major besides it is affected.
For how long have I used the solution?
We have used this solution for over three years.
What was my experience with deployment of the solution?
There were no issues with deployment.
What do I think about the stability of the solution?
There were no issues with stability.
What do I think about the scalability of the solution?
ZVR can handle thousands of VMs, so there were issues with scalability here.
How are customer service and technical support?
Support is very quick in their response time and most of issues are solved in a matter of hours.
Which solution did I use previously and why did I switch?
We were using Veeam Replication which is based on snapshots. However, ZVR has no snaphosts, zero impact on production, and improves RPOs seamlessly.
How was the initial setup?
The initial setup was very straightforward and can be done in less than one hour. You can then start replicating between two sites.
What about the implementation team?
We did the implementation in-house.
What's my experience with pricing, setup cost, and licensing?
Licensing is based on the number of VMs to replicate. The first thing should be to get the number of VMs to replicate based on your business needs.
Which other solutions did I evaluate?
Before ZVR, I evaluated Veeam Replication, vSphere Replication, and RecoverPoint for VMs.
What other advice do I have?
If you need to replicate your VMs with RPOs of seconds, then Zerto is certainly the way to go.

Truly simple data replication.
Valuable Features
ZVR is very simple to setup and administer. Out of the box it just works and allows me to set my replication source and destinations and nearly forget it. Our RPOs are generally 5 seconds on a replicated base of 4Tb so we have only a very small data loss in the event of needing to recover.
Now that v4.5 has been released, I have the ability to recover individual files in the event of accidental deletion or even encryption by Ransomware. This ensures that data is easily recovered no matter when it is deleted, ensuring that files that have been created and deleted in the same day and prior to backup are recoverable easily.
And, perhaps more importantly, out of the box ZVR allows me to test the failover whenever I want to verify that my systems can come up as expected.
Use of Solution
I have been a user of Zerto Virtual Replication for 1 year.
Customer Service and Technical Support
Technical Support at ZVR is very good. Any calls are promptly responded to and dealt with to resolution. The support personnel are very knowledgeable on the product.
Initial Setup
Initial setup is very straight forward. You simply create a group and populate your machines into the group, select a destination and voila ZVR does the rest.

Zerto just works
What is most valuable?
Near-zero RPO, granular selection of individual VMs and the very simple setup and management.
How has it helped my organization?
Reduced DR strategy documentation and procedures.
What needs improvement?
Physical servers would be a nice enhancement. I would also like to see the backup portion really enhanced further.
For how long have I used the solution?
3 Years +
What was my experience with deployment of the solution?
Deployment is so easy, so no.
What do I think about the stability of the solution?
No
What do I think about the scalability of the solution?
No
How are customer service and technical support?
Customer Service:
Excellent
Technical Support:Excellent
Which solution did I use previously and why did I switch?
Yes. The product(s) I was using for replication were not as efficient and could not provide nearly as low of an RPO as Zerto.
How was the initial setup?
Easy
Which other solutions did I evaluate?
Veeam replication, SRM and array-based.
What other advice do I have?
I work for a data center solutions company and DR was always the toughest challenge. I have recommended numerous solutions to my customers over the years but when we stumbled upon Zerto 4 years ago it has become our standard recommendation in these projects. It's easy to setup and manage but best of all...it just works as expected.

Honestly, I'm not well informed in terms of pricing and licensing. My interaction with the product is 100% technical, in terms of architecture, implementation, and operation.
Which other solutions did I evaluate?
Multiple solutions, like Veeam, VMware SRM + ABR.
What other advice do I have?
It's very easy to set up a lab or a PoC to test it. I would recommend doing that because you will be able to see the real value of the product in a very short term.
