What is our primary use case?
Our primary use case is for disaster recovery and migrations. We have two primary sites that we replicate to. If there are on-prem clients we replicate back and forth between those two and then we replicate our off-prems to them as well. We use on and off-prem as well as Azure.
How has it helped my organization?
We actually have rescued a couple of clients that have had disasters on-prem due to weather or data center outages. One of our clients had left us for a cheaper provider and before our disks and retention points expired out, the cheaper provider had a flood in their data center. We were able to restore the client using the old restore points back into our data center, which was a huge win for us because it was a fairly large client. That client has worked with us ever since then.
Zerto saves us time in data recovery situations due to ransomware. We've had a couple of ransomware incidents with clients in the last year and a half. I've worked on ransomware issues before when Zerto wasn't involved and it was much more complicated. Now, with Zerto, it's at least 50 to 75% faster. We're able to get a client up and running in a matter of an hour, as opposed to it taking an entire day to build or locate the ransomware and rebuild from shadow copies or some other archaic method.
It decreases the time it takes when we need to failback or move workloads because we use disaster recovery runbooks that we work with our clients to maintain. Anybody at our company, at any given time, can pick up this runbook and go with it so we can assign one or two techs to the incidents. They work with the client and get them back up and running quickly. We're 50 to 75% faster. It's now a matter of hours as opposed to days. In an old disaster recovery situation, it would be all hands on deck. With Zerto, we can assign out a technician or two, so it's one or two techs as opposed to five to 10.
There has been a reduction in the number of people involved in the overall backup. We have the management fairly minimized. There are only two primary subject matter experts in the company, one handles the back-end infrastructure and one handles the front-end, that's pretty much it. We're a fairly large company, with 500+ clients, so it's been stripped down, so to speak.
From what I've seen, we do save money with Zerto, especially for long-term retention like the Azure Blob Storage. We had a recent incident where a client had to go back to a 2017 version of a server that was around three to four years old, just to find a specific file, and it only took us an hour to locate the proper retention point and mount it for him and get him back what he needed.
What is most valuable?
The testing features are the most valuable features of this solution. We use the failover test feature not just for testing failovers and disaster recovery, we've also had clients use it for development purposes as well as patching purposes to test patches. We can failover the VM and then we can make any changes we want without affecting production. It's a nice sandbox for that usage.
We also use it for migrations into our data center. We bring in new clients all the time by setting up Zerto in their on-prem and then replicating to wherever their destination will be in our environment.
We've also used Zerto to migrate to the cloud.
Zerto provides continuous data protection. I'd give it a 10 out of 10 as far as that goes. The recovery points are very recent, generally five to 15 seconds of actual production. It's very convenient.
It's also fairly simple to use. Zerto does have some quirks but they have worked those out with recent releases. They're really good about listening to feature requests. We're actually a Zerto partner at our company, so they take our feature requests pretty seriously. Zerto is one of the easiest disaster recovery products I've used. We use Veeam as well which is much more complicated to set up in the back-end.
What needs improvement?
Zerto seems to keep up with what I think needs to be improved pretty well.
One improvement that could make it easier would be to have an easier way to track journal usage and a little bit more training around journal sizing. I've done all the training and the journal is still a gray area. There is confusion surrounding how it's billed and how we should bill clients. It would be easier if it had billing suggestions or billing best practices for our clients to make sure that we're not leaving money on the table.
For how long have I used the solution?
I have been using Zerto for three and a half years.
What do I think about the stability of the solution?
Stability is pretty good. It's gotten better over the years. It's kind of 50/50 between features that have been added and our understanding and usage of the product over the last three years. But it's definitely gotten better.
What do I think about the scalability of the solution?
It's highly scalable. That's one of the things we like about it. We can empower clients. I have one client that's migrating from his on-premise into one of our private clouds, and we have enabled him to do so. We set up the environment and we're enabling him to build VPGs and migrate them as needed without our interaction at all. This is bringing in tons of revenue. It's super scalable and it seems to be not just easy for us to use, but easy for us to enable a client to use it as well.
How are customer service and technical support?
Technical support is astounding. I've said that to Zerto technicians and I've said that to clients as well. Being in my role, I work with a lot of vendors, a lot of different support, and Zerto is off the charts as far as skill and ease to work with. It's been wonderful as far as that goes. Zerto was some of the best support I've had across vendors.
Which solution did I use previously and why did I switch?
Before Zerto, there really wasn't anything that was as good as Zerto, so it was a game-changer.
How was the initial setup?
The initial setup is pretty straightforward.
For an off-prem client, I would send them a welcome letter that details what they need to do on their end with the server. I would send the download package, everything like that. If the client is immediately responsive, that could be done within an hour, but then some clients take a little longer. Once they have the infrastructure set up on their end and the VPN is set up, I can have a Zerto off-prem implementation replicating into one of our private clouds within an hour or two hours maximum, even for a large environment.
What was our ROI?
A client was migrating into one of our usage-based clouds, so it automatically bills by the resource pool. The more that they put in there, the more we gain. We've probably increased the input to that environment 10-fold. It's a 10-time multiple of what we invested into it, just particularly for that one use case because he's growing so rapidly. Every time he brings over a new client, it adds to the billing which is hands-free for us. We've enabled him to do it.
What's my experience with pricing, setup cost, and licensing?
Pricing is fair. For the license that we have and the way that it's priced, it is pretty simple and it's not over-complicated like some other platforms. It would be very beneficial to have some sort of training or even just documentation around every component of Zerto and how it should be built or there should be suggestions about how it should be built. It would help newer companies that are adopting the platform to have a better opportunity to grab all the revenue upfront.
Journal history was one of the things that we didn't take into consideration when we implemented Zerto initially and we lost a lot of money there. We talked to one of the reps after that and found out that some clients do roll in the cost of this journal and some clients actually charged separately for it. Zerto has made it easier to plan for that lately with Zerto Analytics, but it's still a gray area.
There aren't any additional costs in addition to standard licensing that I'm aware of.
Which other solutions did I evaluate?
We still use Veeam in the environment but the recovery points aren't as robust. They're a lot thinner. You can get maybe an hour or the same, but you can't get five-second production. We used Veeam and the old active-passive standard of building a server in each environment and replicating to it.
What other advice do I have?
I've actually pushed us to use Zerto for our backups with the solutions team for quite a while, since version 6.5. I don't think they plan on doing it just because we already have two other backup offerings and they don't want to complicate our Zerto infrastructure. From my understanding, we're not planning on doing it. But with every release, it gets so much better and it's just a matter of time before we revisit it.
My advice would be to follow best practices when it comes to back-end infrastructure. We have made some changes specifically to track certain things like swap files and journal history. Previously, we had everything going to production data stores and now we have dedicated journal data and restore data stores for swap files, which helps us to thin out the noise when it comes to storage. Storage implementation is very important.
Make sure to go through all the training. The training on MyZerto is free, very straightforward and it's very informative. That's one of the things we didn't do initially but it wasn't really as available as it is now.
I would rate Zerto ten out of ten.
