"I like the fact that you can recover the VMs inside the appliance. For example, they're basically running this appliance on a Linux-based distribution, and they're spinning off KVM virtual machines inside."
"It's not easy to scale it."
"I really like the reporting options you get for various email reports."
"They have great support."
"When I have had to use tech support, they've been very good."
"When we talk about a backup point of view, from a backup perspective, it's a good one."
"The return to operations is the most valuable feature because it decreases the amount of time it takes us to recover."
"We relocated all our virtual machines from Belgium to Budapest, Hungary. I am not sure how we would have done it without Zerto, because we were able to keep the data in sync. We would have needed to have a lot more expensive storage products online at the time that could have kept that replication. From what I have seen from other methods, that would have required a much higher amount of bandwidth as well, then the cost would have been extreme. The mechanisms available to us with a storage space replication would have been more labor-intensive and prone to error. It was much easier and more successful with Zerto than other ways at our disposal."
"We own another solution called VMware Site Recovery Manager, SRM. We have licenses for our entire environment and we still decided not to use it. That's how big the difference was in the experience that Zerto provides."
"The most valuable features are the continuous streaming, that it takes very little CPU usage — it doesn't affect production — and the recovery time is very short."
"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 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."
"It is convenient to use because the API allows for seamless integration when performing our day-to-day operations."
"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."
"There's a lot that can be made better. For example, it could be more scalable."
"I would like to see the real-time replication process improved, and a zero RPO feature added."
"I would like to see more storage options for the free version."
"It seems like Unitrends moved away from enterprise customer engagement and moved more towards the managed service provider market."
"Probably the biggest issue I've had is actually paying for the unit, and part of that problem is that they use a third party for the billing."
"Comparing the features and the working pattern, definitely they have to come down on pricing if they want to compete in the market."
"Zerto should add the capability to replicate the same VM to multiple sites."
"I am a little bit worried about how Zerto will work with large volumes of data, such as replication for big data and very large files."
"The monitoring and alerting functionality need to be improved."
"We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement."
"They definitely have room for improvement in a couple of areas. One is role-based access control. Right now, they don't have an identity source so they use the identity of the vCenter or the VMM. If they connected to an identity source like Active Directory and allowed for granular roles and permissions, that would be an improvement."
"The onset of configuring an environment in the cloud is difficult and could be easier to do."
"The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited."
"The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates."
