What is our primary use case?
We were able to replace most of VMware SRM with this solution. It allows us to failover individual machines or application clusters with ease. The one thing that it does not do nicely is a full site failover. We have never needed that aspect though (only for testing).
How has it helped my organization?
We have leveraged the individual server failovers a number of times, and it has saved us a lot of man hours (doing things such as rebuilding, fighting viruses, or forcing more servers to failover than we wanted). It has been a phenomenal addition, and proved its worth in the pilot phase, when it saved us from having to rebuild a machine that was included in our pilot trial.
What is most valuable?
Journaling allows us to leverage Zerto's journal for sub-minute recoveries, instead of having to wait for the storage array to replicate. The solution is well worth the money invested.
What needs improvement?
The full site recovery is not up to SRM standards. Within a VPG, you can do great failover timing as well as ordering and scripting, but if your site contains many VPGs (as mine does), then it is difficult to manage failing over between sites, especially if you are at the site that was impacted.
For how long have I used the solution?
Less than one year.
What do I think about the stability of the solution?
None. Even the upgrades are speedy and easy.
What do I think about the scalability of the solution?
None. As long as you have the licenses, it goes smoothly.
How are customer service and technical support?
I have contacted their vendor support in regards to backup performance of SQL databases. They provided me with adequate instruction and background information to be able to adjust my environment to better suit Zerto's processes. It's been smooth sailing since.
Which solution did I use previously and why did I switch?
VMware Site Recovery Manager. We changed from this vendor because we hit the 75 license threshold and were forced to consider the conversion to Enterprise. We searched the marketplace and Zerto was a great fit for our needs.
How was the initial setup?
It was straightforward and easy. I was able to install it myself without any help from Zerto.
What about the implementation team?
In-house was all that was necessary. It only required one engineer to work for about two hours to install everything, and then a week to configure and protect the entire environment. This will vary depending on your link to your DR site.
What's my experience with pricing, setup cost, and licensing?
The cost is steep, but once you experience recovering a single server along with its granular restore times, you will see that the cost is justified.
Which other solutions did I evaluate?
What other advice do I have?
Make sure that you understand the limitations of any software before you dive in. Make sure you document your use cases and have the vendor show you how it can perform those tasks.
