Zerto Reviews

The setup is easier than most products, and for us as a cloud partner, once a customer is trained to create VPGs, they are good to go.

• The replication being log-based is awesome. 
• The VMDK can be preloaded to the remote site or allowed to come across the WAN, then the logs just keep flowing.
• 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.
• You can practice failovers (start the replicated virtual machine at the remote site) while the logs keep stacking up. The replicated machine can be open for a few hours, but short times are best depending on how much data is changing.
• Files can also be extracted from the VMDK at the remote site even when the VM is off.
• In case of a disaster, a single mouse click sets the restore to the real failover; click the Failover button, the VM on the replication site is started, while the VM at the source site is shut down. Once up, reverse replication begins and stays in log replication until the systems are reverted back to normal via the same process.

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.

No issues with stability. The delivered upgrades and major updates are stable.

No issues with scalability, it pretty much takes care of itself. One does have to watch where all the recovery site systems are located, to avoid running out of space on the datastores. We can control/move recovery VMs as necessary.

Awesome. Their helpdesk people are among the best.

The product needs a VPN tunnel from the customer site to ours. VPNs can be tricky depending on the compatibility of the hardware. The programs themselves are a snap, and surprisingly small.

Cloud providers get good pricing to encourage quick adoption. A new feature is the One-To-Many VPG allowing a VM to be replicated at up to three different locations, including local.

As a cloud service provider, we have many tools to satisfy the needs of the customer. We have used Asigra, Veeam, StorageCraft, as well as Zerto. Each has its strengths. The market is heating up because of CryptoLocker and other viruses.

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 or major release.

In terms of advice, I would say become VPN, as well as VMware or Hyper-V, savvy.

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. 

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.

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.

I cannot think of any new features that should be added at the moment. With time, I should be able to make suggestions.

None whatsoever.

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.

10 out of 10.

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.

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.

We implemented through a vendor team. They were very experienced and were able to provide detailed answers to all of our questions.

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.

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. 

No, we did not. When we did our research, Zerto was the name that always came out as the market leader.

Simple, fast install

Easy upgrades

Grouping virtual machines by application, not LUN

Automatic IP address change

Simplified the way annual DR tests are performed as well as being a tool for migrating workloads between data centers as needed.

Would like to see additional reports after recovery operations with details on recovery of each VM

2 years

Sales and customer service are responsive to questions.

Technical Support is very helpful. They reply to phone or email quickly.

Used VMware SRM previously

Straightforward, simple deployment

Near-zero RPO, granular selection of individual VMs and the very simple setup and management.

Reduced DR strategy documentation and procedures.

Physical servers would be a nice enhancement. I would also like to see the backup portion really enhanced further.

3 Years +

Deployment is so easy, so no.

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.

Veeam replication, SRM and array-based.

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.

My primary use case is doing demos and testing to make sure that Zerto is going to work for our customers. I test it mainly for disaster recovery and backup.

We've tested with VMware, Zadara, and AWS.

My clients found the DR feature to be the most valuable. It's something they deal with daily from a virtual machine using VMware, Amazon, or Azure.

Zerto absolutely helped to reduce downtime. My customers can bring up their machine somewhere else, and they can test on it.

Zerto's speed of recovery is very fast and efficient whenever I tested it.

Zerto added the backup feature, but it's not quite up to speed yet when you compare it with the backup capabilities of other solutions out there.

I've used Zerto off and on for about a year and a half.

The stability is good, and I have never had any customers say anything bad about it. Some have used it for years and have not had any problems.

Zerto can be scaled to any number of servers that you need.

My customers have used Zerto's technical support and had no problems with it.

My clients loved Commvault from a backup side of things, but Commvault just didn't do the DR right for them. It was not quick real-time DR. They brought in Zerto, and it worked phenomenally for their production systems.

From a backup perspective, Commvault is really good, but from a DR perspective, Zerto is way better. It's much quicker and easier to use, and it works right out of the box.

My customers said that though they had to pay for it, they were glad they bought it because Zerto works. It's got really great ROI coming from that perspective.

The licensing model is good. The price is a little bit expensive, but for what customers get on it, it tends to pay for itself. However, if more and more companies start to improve, then Zerto may need to look at their pricing and make it a little better.

We evaluated Veeam, Cohesity, and RackWare. Zerto is by far the best disaster recovery product out there.

You should set it up, test it on a few machines, and also test it in multiple environments. Most people have multiple clouds, so make sure you try it with VMware, AWS, etc. Also, decide whether you want to do all your critical tasks with Zerto and fully plan your DR as the top-level. Determine what is most important and then scale it down to the least important. You can then implement Zerto from that perspective.

Overall, I would rate Zerto at nine on a scale from one to ten.

Replication for disaster recovery between data centers is valuable.

Zerto allows us to replicate entire systems between data centers instead of setting up replication within the applications, which sometimes is non-existent.

The backup capabilities require too much disk space and I would like to see better compression. or deduplication built in to reduce the amount of WAN traffic. It would also be nice to have it be able to monitor a VM to let you know how much bandwidth a particular VM would require to replicate.

I've been using it for nine months.

We have had no issues with the deployment.

There have been no performance issues.

Scalability is all about bandwidth, so the only issue we had was trying to guess how much bandwidth we would need.

Technical support is good.

We used point solutions for our disaster recovery needs and we were very selective about the applications we would setup with disaster recovery due to costs.

The Zerto setup is very easy. The difficult task is setting up any processes that need to be run after a failover.

This was all setup in house.

Being able to provide customers with DR options that work.

We are a Cloud Services provider that owns and operates data centers coast-to-coast.

Only slightly when using it to protect 37 SQL servers. The high IOPS have been dealt with and we have solved that issue.

We used many other solutions, but this is the one we reached for first.

Yes - super simple.

When you can't afford to risk your data, Zerto is the solution.

We use this solution for disaster recovery.

Implementing this solution has given us sandboxing and the ability to move VMs. These are nice to have tools.

The most valuable feature is the Restore file, where you can go back in time on a file-level. This is very helpful.

The backup functions are in need of improvement.
