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.
"The most valuable feature of the solution is that you can independently run the disaster recovery without disturbing the production instances."
"The most valuable feature is disaster recovery testing."
"The product is evolving and the vendor is committed to change."
"The product functionality is fairly high-quality."
"Virtual Machine Recovery during DR situation, with automation and easy to use menus and options."
"The thing I like the most about SMR is the reduced cost of management."
"It is a stable solution...The solution's technical support is excellent."
"The stability of SRM has been excellent. It gets a nine-out-of-ten."
"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."
"The orchestration and automation of the DR and how it replicates the VMs and then picks them up in the DR site have been most valuable."
"The replication for DR is really good, and the test failover within the application is really solid, along with the ability to manipulate RDMs or remove them."
"It's also very much faster than any other migration or disaster recovery platform we have. I work with virtualization, mostly on VMware, and I must admit that Zerto is even better than VMware Site Recovery Manager. Zerto compresses the data and it works much faster."
"Since we are at a bank, there are certain protocols in place where we need to have RPO and RTO times of two hours or less. Zerto does a great job of setting those times and alerting us if those can't be met. We have our help desk actively monitoring that. It is extremely helpful that Zerto lists what is falling out of compliance in regards to RPO and RTO. It has been great in that regard."
"The Zerto university for training staff is very useful."
"The ability to perform DR testing to ensure data integrity is critical."
"Zerto has improved our restoration time and made it easier to test software upgrades. It has simplified tasks like decommissioning a site and replicating virtual machines from one location to another."
"There are many functionality problems with the product currently. It is also slow and unstable."
"Technical support can take some time to respond."
"There is room for improvement in the automation and orchestration aspects of this solution."
"Flexibility to choose different PITs would be nice."
"The version we are currently using is not the latest and greatest but it has buggy behavior in some browsers."
"The biggest issue for us is that this product does not have any demo for customers."
"VMware SRM lacks certain functions that other platforms have, such as better prioritization of allocation of resources and Boot profiles."
"Technical support needs improvement, they are not very responsive."
"There's a mandatory VMware version, so we need to update our VMs in order to access our data. Zerto should work with all VMware versions."
"It would be helpful if the reports can be generated periodically, on a schedule."
"I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better."
"Zerto should add the capability to replicate the same VM to multiple sites."
"I would like to be able to replicate one to multiple without having to recreate every VPG. That would save us a lot of time. When we add a site or move our DR to a different site, I have to recreate everything from scratch. So, it'd be cool to be able to just repoint an existing VPG to a new site without having to recreate everything."
"We would like some of the real fine or granular things. We've submitted a few minor things for enhancements such as being able to control bandwidth utilization for each facility you replicate to versus overall. We just need a little bit more granularity on some of the things, but there is not a whole bunch that is in need of tweaking."
"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's one feature that SRM had that Zerto doesn't have, and it's one that we've been asking for. With the orchestration part of the failover, with our DR and our primary sites, the IP addresses are almost identical. The only difference is one octet. With SRM, we could say during a failover change. With Zerto, we keep hearing that it's coming, but we haven't received it yet. It's a feature that would be very beneficial. It would reduce the time a little bit more."
