What is our primary use case?
We use Zerto as a robust failover and replication solution.
Currently we replicate about 50-55 VMs to our DR site. We have run multiple test failovers, and have even done a full-scale, full company REAL failover. Zerto worked flawlessly.
We use Zerto to make sure that our primary Server farm is replicated and protected in case of a failover.
How has it helped my organization?
Zerto gives us peace of mind. It is also extremely easy to use and very intuitive. We don't have to worry about what would happen if our server room were to be damaged or our building destroyed. We always have that big red button available to failover to our DR site which Zerto does flawlessly and easily. We also have peace of mind with their Technical Support, which has always been nothing but stellar for us!
What is most valuable?
I love all the features really.
The fact that the interface is so intuitive is wonderful. The setup and customization of VPGs are great too. They allow you to customize all of the IP information and even the MAC (if you wish) for any and all VMs, allowing you to change the IP or Gateway, or whatever for any VM you might failover.
It is incredibly granular and I really appreciate that. Zerto has also caused us to organize our datastores in a better fashion that makes sense so that they are by priority and not just random.
What needs improvement?
I have brought this up to support before, but it would be really nice to have the option to "roll back" a particular VM to a previous time in the past if it were to become damaged, compromised, or infected. Zerto does not allow this. It's all or nothing, so you must roll back the entire VPG. You cannot roll back a single VM unless that VM is ALONE in a VPG all by itself.
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. I do not understand why a single VM with mass amounts of changes should impact the journal history of the entire VPG. Although this has never caused me problems, it is an annoyance for sure.
For how long have I used the solution?
We have been using this solution for a little over two and a half years.
What do I think about the stability of the solution?
Zerto is literally one of the most stable solutions we have. If we have any kind of bounce, drop, or failure on our fiber line to our DR site, Zerto quickly recovers and catches everything up as soon as the failure is remedied.
What do I think about the scalability of the solution?
It is incredibly scalable and easy to use. I think that's what makes it so valuable and attractive, especially to those who do not have a DR solution.
How are customer service and technical support?
Support is VERY important, and Zerto knocks it out of the park!
Every time I have called Zerto support, the person I have spoken with has been well informed and knew their stuff. Even if they couldn't readily solve my issue, they quickly escalated to someone that could. They are probably the best vendor we deal with in our IT Dept.
Which solution did I use previously and why did I switch?
We had tried other solutions in the past including SRM and RecoverPoint for VMs. I can tell you they all pale in comparison, not only in functionality and user-friendliness but in support as well.
How was the initial setup?
The initial setup is very straightforward.
They assigned us an engineer and we were set up and replicating within two hours.
What about the implementation team?
We used a Zerto engineer, who was assigned by our Zerto sales rep.
What was our ROI?
The ROI with Zerto can't even be measured. The peace of mind we have gotten from knowing that all of our protected VMs are safely replicated with almost live RPOs is something that you can't even quantify.
What's my experience with pricing, setup cost, and licensing?
I would suggest getting a dedicated, well-informed rep. I'm sure they all have great training but always hold your rep accountable. Ask lots of questions because there are no stupid questions.
Which other solutions did I evaluate?
We have evaluated SRM, RecoverPoint for VMs, and other "built-in" Hyperconverged replication solutions.
What other advice do I have?
Zerto is literally the best vendor that we deal with overall as an IT Department. They have always delivered, and have always been top-notch. I highly recommend them to ANYONE, regardless of whether or not they already have a DR solution. Zerto is better.
