We performed a comparison between VMware SRM (Site Recovery Manager) and Zerto based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Zerto wins out in this competition. Its consistent sub-second response for RTO and RPO makes it one of the most responsive and fastest in the marketplace today. Users are able to easily run tests and change scenarios without any effect on an organization's production.
"It is easy to implement for my clients."
"The most valuable feature is the simplicity of operations."
"The most valuable feature of the solution is the automatic recovery of the virtual machine if it goes down."
"The product functionality is fairly high-quality."
"My impression is that the initial setup process is relatively straightforward."
"In terms of resiliency, the most valuable aspect of SRM has been its effectiveness."
"The solution is very flexible."
"It's very reliable. The solution is stable."
"The most valuable feature of Zerto is its overall flexibility, where it can be used for standard DR or you can also use it for server migrations, data center consolidations, etc."
"The journaling is the most valuable aspect of the solution."
"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."
"We've seen a massive benefit from using Zerto in terms of time savings and consistency. You see a consistent outcome every time you do the conversions. We're moving from one platform to another, but the payloads in what we're moving are different. We see consistent delivery."
"The most important feature is that the recovery point (RPO) is less than one minute. The is really good for our customers, as they can keep their data loss to a minimum."
"Zerto has helped reduce our organization's DR testing to seconds to minutes. We have been able to save probably close to 200 hours a year."
"Real-time replication is a valuable feature, ensuring that changes made to the production site are immediately reflected at the recovery site."
"You can set the number of days a VM can be rolled back in case of corruption or virus infection."
"The price, in general, could be lower."
"An improvement for SRM would be better interface compatibility with other products."
"The back sites sometimes are very, very complicated."
"The user experience could be more friendly."
"If you have a failover case, you need to work on it manually. It would be helpful if this could be automated. It would simplify things."
"There are many functionality problems with the product currently. It is also slow and unstable."
"In my opinion, the integration with Peer Persistent Storage could be improved."
"Technical support can take some time to respond."
"I don't like the evacuation process. The host evacuation process could be a little simpler too. It takes our maintenance a bit longer, when we are doing host maintenance, because we still need to evacuate the vRAs manually. I know they tried to make it more automatic, but it is not quite there yet."
"There should be more comprehensive cyber recovery capabilities."
"Zerto's near-synchronous replication is excellent when it works. I'm trying to be nice to them because I like the product a lot, but we're having a lot of difficulty with it in our environment."
"It needs to support more public cloud."
"The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."
"A slight disadvantage of Zerto is that it requires the Windows Server operating system as the base OS. Over time, I would like to see more offerings in that regard. There should be more deployment options other than just the Windows operating system."
"The biggest improvement would be exporting VPGs and a configuration of VPGs, as well as increasing or improving their IP customization rule set."
"The solution is very expensive."
