What is our primary use case?
Disaster Recovery and quick file recovery. We have used Zerto to recover from Ransomware three times. Between the attacks we have recovered over 2 million files. We have never paid a ransome. Our users were only affected just under two hours with the attacks, majority of the time is actually figuring out in the office which pc actually had the crypto locker program running.
How has it helped my organization?
Zerto was able to use an EMC PROD SAN, and a HP DR SAN with no issues or compatibility problems which allowed us to avoid buying expensive hardware for a DR site.
Zerto has allowed us to feel comfortable our data is being replicated, and the data is not corrupted.
What is most valuable?
Zerto is packed full of useful features. The main feature is easy to manage, you will not need to be in Zerto day to day as it runs flawless.
Zerto has a plugin to integrate seamlessly into VMware VSphere tab.
I would highlight is the fact Zerto was used to migrate all of our VMs from one data center to another data center (two different physical locations) when we upgraded to new hardware. The migration was a breeze.
My second valuable feature is being able to click just a few points in the program to initiate a test vm recovery at our DR location. After testing, all test VMs are deleted along with the data. This is automated, you do not need to interact with deleting VMs.
In Zerto depending on your hardware and internet connection between your production site and DR site you can expect an RPO of 15 seconds.
As of the summer 2016, Zerto just created an extremely fast way to recover files from their journal. Instead of going to our long term backup program and taking a half hour or longer to find a file, Zerto is getting me the file in 4min. This is making my life easier and keeping users happy.
What needs improvement?
I would like to see Zerto come up with an emergency line for support. Support does get back to you quickly, but when your heart is racing because something happened the calmness of a pro on the other end would be helpful. The reports also need TLC, as I do not really find them helpful.
With these two minor negatives the product and support are great and they get the job done. I am an extremely happy Zerto supporter.
For how long have I used the solution?
One to three years.
What do I think about the stability of the solution?
The only issue with stability was when I caused the issue by changing VM settings in the DR site. This was a great test for support, they took care of the issue quickly and got me back up and running.
I consistently see 8-18 seconds RPO. We test DR by adding a file to a server, then 1minute later launching the test failover to a site that is 6 hours (drive time) away. The file will be there in the DR bubble.
What do I think about the scalability of the solution?
We added new VMs with no issues, the only issue to keep in mind is the more VMs you add, the more storage your DR needs.
How is customer service and technical support?
Outstanding! Pre-sale we had someone with Zerto actually come to our office and make sure this was the right choice for us. After we went live we had a few calls (initiated by Zerto) making sure we were happy and everything was running smooth. We still get periodic emails checking on us. I have not seen that with other companies.
On the Zerto team, Jennifer and Ciana helping us in our times of need.
Tech Support is all initiated by email, but then Zerto will call you if needed. This avoids phone cues. The person I talked to the two times I called in were awesome, they were very knowledgeable. Even though I caused one of the issues that needed fixed by support, they did not treat me with any disrespect even though I caused the issue. The tech did explain how to correctly do the tasks.
How was the initial setup?
We had a very experienced consultant set us up.
What other advice do I have?
My advice for someone thinking about Zerto is to do the trial run that Zerto offers, you will be impressed. If you are looking to get RPO's of 30seconds or less, Zerto can do it. I typically see 8-18 seconds RPO. Needless to say this depends greatly on your WAN link.
I highly recommend going to Boston in 2017 and meeting the staff at Zertocon!
