I would not do a virtual based disaster recovery solution without this tool

What is our primary use case?

Cloud-based disaster recovery. However, do your homework on your provider. There are several options besides Azure and AWS that don't have their surprise charges. Be sure to check them out.

What other advice do I have?

No.

Easy to operate and very dependable.

What is our primary use case?

Disaster Recovery and quick file recovery. We have used Zerto to recover from Ransomware three times. Between the attacks we have recovered over 2 million files. We have never paid a ransome. Our users were only affected just under two hours with the attacks, majority of the time is actually figuring out in the office which pc actually had the crypto locker program running.

What other advice do I have?

My advice for someone thinking about Zerto is to do the trial run that Zerto offers, you will be impressed. If you are looking to get RPO's of 30seconds or less, Zerto can do it. I typically see 8-18 seconds RPO. Needless to say this depends greatly on your WAN link. I highly recommend going to Boston in 2017 and meeting the staff at Zertocon!

We were able to start replication within minutes of the initial setup

What is our primary use case?

Virtual server replication, as well as a level of backup, to our disaster recovery site.

Pros and Cons

  • "During a failover to a DR site, Zerto can automatically change the IP address of servers."
  • "With Zerto, we were able to replicate our virtual servers to a remote DR site across a WAN connection."
  • "The initial setup was very straightforward and easy. We were able to start replication within minutes of the initial setup."
  • "I would like them to add a VM host replication option. Being able to replicate host configuration between sites would be a huge benefit."

What other advice do I have?

For the most part, we are very satisfied with Zerto and its features.

Journaling allows us to leverage for sub-minute recoveries

What is our primary use case?

We were able to replace most of VMware SRM with this solution. It allows us to failover individual machines or application clusters with ease. The one thing that it does not do nicely is a full site failover. We have never needed that aspect though (only for testing).

Pros and Cons

  • "Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate."
  • "The full site recovery is not up to SRM standards."
  • "It is difficult to manage failing over between sites if you are at the site that was impacted."

What other advice do I have?

Make sure that you understand the limitations of any software before you dive in. Make sure you document your use cases and have the vendor show you how it can perform those tasks.

Continuous VM replication and ability to choose recovery point are key

Pros and Cons

  • "Failover using Zerto is simply a one-button click, and it does everything else in restoring the VMs at a different datacenter (recovery site)."
  • "Zerto is an excellent solution for cloud-based environments, but for DIY clients who have another site to recover their systems it also works well."
  • "Adding or changing VPGs (Virtual Protection Groups) may require restarting replication."

What other advice do I have?

The product works and does what is says. Zerto provides enterprise-class, virtual replication and BC/DR solutions for private, hybrid, and public clouds. Future releases will provide multiple destinations/locations to store the replicated data. Most companies have used backup software for their protection, or disk array replication. Zerto leapfrogs those data protection methods and provides a much more affordable BC/DR solution, with improved RPO and RTO. Zerto is an excellent solution for cloud-based environments, but for DIY clients who have another site to recover their systems it also…

Continuous log file transmission means the granularity of restores is amazing

Pros and Cons

  • "The replication being log-based is awesome."
  • "You can set the number of days a VM can be rolled back in case of corruption or virus infection."
  • "Since the log files are continuously transmitted, the granularity of restores is amazing."
  • "Files can also be extracted from the VMDK at the remote site even when the VM is off."
  • "An integrated encryption would allow for faster initial install and connection to the remote cloud site."
  • "Their offsite backup is a bit clunky, but it will probably improve."

What other advice do I have?

There are many products on the market that perform Virtual Machine replication. The other products use Snapshot technology which can have issues with Hypervisors or large disk volumes. The datastore or shared disk (depending on Hypervisor) must have enough free space to allow the Snapshot to be open for as long as the backup runs. This can lead to crashes and consolidation issues, which are usually painful. Zerto is a log-based replication product, for that I give it a 10 out of 10. I've been using it over a year now, and the product has kept improving. It is easy to upgrade to the next minor…

Gives us efficient replication over narrow WAN bandwidth

Pros and Cons

  • "VMware VM replication over narrow WAN bandwidth."
  • "It needs to support more public cloud."
  • "It works only for a virtual platform, it does not support bare metal."

What other advice do I have?

It works only for a virtual platform, it does not support bare metal. If you're looking for a comprehensive solution for both virtual and physical platforms, then Veeam is a preferable solution.

The journaling capability allows you to recover from a ransomware attack.

What is our primary use case?

In our case, we used Zerto Replicator mainly for DRP (Disaster Recovery Plan), but also for testing.

What other advice do I have?

It is important to have clear: * Required links between sites. * Available network (ideal network L2 inter sites). * Capacity for journaling (+/- 7%) in contingent site.

Can quickly recover from any disaster with very little downtime utilizing a user interface that requires minimal experience

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.

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."

Managing the system is easy and reliable, you can choose any VM you want to replicate to your DR Site in Combination with other VM's.

What is our primary use case?

We use the ZERTO Implementation to pretend critical VM and Groups of VM (Application Consistency) from failing. The solution with ZERTO helpy us to TEST and Failover without pane. Installaion is based on local primary site and remote desaster site with a distance of a few 100km and a bandwith up to 30Mbit.

Pros and Cons

  • "Managing the system is easy and reliable, you can choose any VM you want to replicate to your DR Site in Combination with other VM's."
  • "Migration of complex VMware and Hyper-V solution. Using Zerto to replicate to azure and S3."

What other advice do I have?

With the next generation Zerto5.5 they allow replication and production in azure, so cloud based DR comes reality. Everybody who looks for alternative solutions in physical sync mirroring of data (Metro-cluster) should think about business needs and ABC (Application Business Continuity) Zerto can do it and helps you to keep business online with less cost than other solutions.

You can clearly see if something is not quite right in your disaster recovery plan before you have an actual disaster

What is our primary use case?

We primarily use Zerto Virtual Replication to protect groups of servers in our production data center, replicating them to a secondary site. We also protect essential test and dev servers. I have also used it in a past role to carry out a datacenter migration project.

​Provides a simple wizard to install, but is missing compatibility with multi-tiered applications for testing

What is most valuable?

It is easy to setup and manage.

How has it helped my organization?

Provides a simple interface for VM DR.

What needs improvement?

Needs compatibility with multi-tiered applications, such as Sharepoint, for testing.

For how long have I used the solution?

One to two years.

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?

Fair, depending on which location you get in contact with: They can be difficult to deal with and don't understand the product in which they are servicing.

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

Not applicable.

How was the initial setup?

We have helped several customers implement their Disaster Recovery Plans more easily than before, thanks to the independence of hardware that the product provides

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.

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 other advice do I have?

If you need to replicate your VMs with RPOs of seconds, then Zerto is certainly the way to go.

Has a simple process to protect or migrate a virtual workload.

Pros and Cons

  • "It enables protection of a virtual workload to be done by the app, whether single or multi-tiered, with a boot time scheduler. It is pretty awesome."
  • "Zerto is solid. However, they are working on a cloud workload protection and protecting virtual workloads to more than one site."

What other advice do I have?

Put it in place as it will become your default tool for VM protection and replication, hands down!

Has a significant impact on moving the data center across various sites with perfection

Pros and Cons

  • "Failing over the VM without removing/touching the production VM from inventory is also an important feature."
  • "There is a need to allow the source vCenter Inventory to be imported with a single click."

What other advice do I have?

Just buy it with eyes closed, no requirements are needed. It works with various VMware versions. This is the most amazing hypervisor-based replication that I have ever used.

The two key features for AssureStor are hypervisor based replication and the automation for failover, testing and failback.

What other advice do I have?

Zerto, in my opinion, is one of the best DR products on the market currently, its only flaw (if it can be called that) is that it is limited to virtual environments, specifically VMware & Hyper-V (it does also support replication to AWS if needed). If you are looking to streamline your DR capability and remove risk then speak to Zerto and get them to run you through a demo, what they say the product can do is not sales talk, it really can do it.

It's HW agnostic, with no impact on production systems, but backup dedup and online restore need improvement.

What other advice do I have?

There are other competitor on the market, but this is the only one dedicated to DR. All others are backup based. It could seems expensive, but when you realize its power, you'll understand that cost is justified.

​Replication from Hyper-V to ESX so that I can retire my old environment is nice. The ability to add hard disks to a VM and have Zerto just pick up those changes would be improvements.

What other advice do I have?

The product has significant promise but it’s a long way from fully functional, there are fantastic features in the product and fantastic features promised “in the next release” too. Make sure you run through a good sizing exercise first.

This product is very easy to use and administer. One thing to be aware of is that the vSphere side and the AWS side will have two separate installers.
Zerto has been a great product for companies looking to deploy an easy to use disaster recovery solution.

What other advice do I have?
