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.
"This SRM solution can improve your footprint within a data center."
"The most valuable feature of the solution is the integration part, along with the subsequent hardware."
"The solution is simple to use and has effective automation."
"VMware is one of the best products in the industry when it comes to virtualization."
"The UI is very user-friendly and testing is easy."
"It is a very stable solution...I was involved in VMware SRM's deployment phase two years ago, and it was an easy process."
"It is a stable solution...The solution's technical support is excellent."
"I would rate the ease of setting up and configuring my recovery plan in VMware SRM, a ten out of ten, with ten being the easiest."
"We are in the process of switching over our production data center and Zerto has been a true time-saver that has cost us zero downtime."
"You can set the number of days a VM can be rolled back in case of corruption or virus infection."
"The mobile application is very useful as a real-time monitoring, reporting tool. When asked the status of our machine backup and recovery ability, an easy answer is to display the status on the real-time application or browser. The Zerto Analytics tool helps predict future storage needs by tracking trends in space, journal size, and I/O rate. These are reportable statistics making quantifiable tracking easy and accurate. Having a web interface simplifies access by other system administrators."
"Using Zerto, you can have your VM up and running in a matter of minutes. All you need to do is flip a switch, then you are good to go."
"Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."
"There are several valuable features because of the way we use it. The backup and restore features are definitely indispensable."
"Real-time or near real-time replication has been the most valuable feature. Our RTO is generally between six and eight seconds. The impact on our RTO is essential."
"The one-to-many replication functionality is helpful. While we were protecting our VMs in Azure, we were able to use the one-to-many feature to also replicate the same VMs to our new data center, in preparation for data center migration."
"Timing issues arise due to replication lags in multiple areas. When this happens, we encounter errors."
"We would like the patching management function of this product to be improved."
"The two vCenters have to be synchronized, which sometimes gives us problems because Keberos does not tolerate more than five minutes in time difference."
"SRM has to be installed on two separate data centers, so both have to be coordinated very well, which becomes complicated when configuring the software for disaster recovery."
"VMware SRM needs to improve its pricing."
"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."
"Currently, there is a limitation of consolidating only 15 sites per SRM."
"The product's dashboard is an area of concern where improvements are required."
"An area for improvement is the support because it gets really expensive. They need to make it a little cheaper. Support also takes time."
"I would like Zerto to add support for VMware's lifecycle manager."
"I would like to see some improvements with APIs going into the cloud so that they can more natively orchestrate the migration point-to-point without special hands-on configuration. Azure does some of that natively by having an agent on the VM, but Zerto could improve on its APIs into Azure or Google so that spinning up works more natively in that environment. It would make things smoother."
"The RPO for our SQL server has room for improvement."
"The email alerts can be excessive, so better control over frequency or resolution may be a worthwhile improvement."
"It would also be nice if they could find a way to make it where one VM does not impact the entire journal history of the VPG."
"We encountered some issues during Active Directory recovery."
"They just came out with improvements for ransomware protection last week. I haven't used them yet but, overall, security and preventing ransomware is really a hot topic these days. I would like to see it detect when the ransomware occurs and provide more information on it."
