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 thing I like the most about SMR is the reduced cost of management."
"The solution is strong when it comes to protection and analytics, with the latter being added later on."
"SRM's best feature is automation."
"It is easy to implement for my clients."
"The most valuable feature is the simplicity of operations."
"The most valuable features are the disaster recovery and testing."
"The most valuable feature of the solution is the automatic recovery of the virtual machine if it goes down."
"It is a very stable solution...I was involved in VMware SRM's deployment phase two years ago, and it was an easy process."
"If we lost our data center and had to recover it, Zerto would save us a great deal of time. In our testing, we have found that recovering the entire data center would be completed within a day."
"The most valuable features are the single pane of glass and the reduction in time it takes for our systems engineering team to manage the platform."
"The replication feature and DR functionality are most valuable. Zerto has many options when a new server is being provisioned."
"The low RPO times of about four to eight seconds are very nice and very valuable to us."
"I've been fortunate enough not to need to rely on Zerto in an actual disaster, but we do testing every year. Sometimes, it's multiple times annually or at the year's end. It takes the recovery workflow, which would normally take a lot of planning, and reduces that to just a few minutes."
"It is way faster than just manually moving VMDKs, etc. It saves hours of time and a significant amount of money."
"Zerto's two main features are ease of management and that the product just works. It does what they say it'll do."
"The replication feature where it constantly replicates and sees that data is always in sync is valuable."
"The primary site lacks adequate equipment, such as power backup and cooling, which can lead to downtime during issues like power outages or overheating."
"What I think can be improved is the data replication aspect."
"The technical support is not very good and needs to make an effort to improve."
"Technical support needs improvement, they are not very responsive."
"The price, in general, could be lower."
"The solution is on the expensive side."
"We would like the patching management function of this product to be improved."
"The back sites sometimes are very, very complicated."
"If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."
"I would like Zerto to add support for VMware's lifecycle manager."
"Zerto could improve its reporting capabilities."
"It is crucial for Zerto to collaborate closely with VMware in order to promptly test updates."
"The number-one area in which they need to improve their product is what I would call "automatic self-healing." This is related to running them at scale... We have 1,000 VRAs and if any one of their VRAs has a problem, goes offline, all of the customer protection groups and all of the customers that are tied to that VRA are not replicating at all. That means the RPO is slipping until somebody makes a manual effort to fix the issue. It has become a full-time job at my company for somebody to keep Zerto running all the time, everywhere, and to keep all the customers up and going."
"The replication layer can probably be improved."
"An area for improvement is the support because it gets really expensive. They need to make it a little cheaper. Support also takes time."
"We do have some sites that are very low-bandwidth sites. Zerto is able to set throttling in the solution, but the throttling is set at a site-wide level. In those instances that have very low bandwidth, I can't reduce the throttling on that site. It would be nice if there were a way to control the throttling by the protection group for a specific workload."
