Zerto Pros and Cons

Zerto Pros

In situations of failback or moving workloads, it saves us hours. If I were to have to move a four or five terabyte machine using something like VMware's virtual copy it has to install on the machine and copy the data over. Then it has to shut the machine down and do a final copy, which means there's a lot of downtime while it's doing the final copy.

Most of the time, this is at least a two person job. We used to have three people doing it. Previously, when we had a disaster recovery drill, the way it worked was 12 of us would show up in the office on a Friday night and work overnight from 12:00 AM on Friday night to 8:00 AM in the morning on Saturday. Then, three of us would be working for four hours out of those eight or nine hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I just stay onsite to help and assist anybody else as they need during that time frame and my work is done in about a 30-minute time frame. This is compared to the four or five hours it used to take for the three of us to do it.

The most valuable features of this solution is the ease of use. In the event of a disaster, you don't need a technical person to actually run the software. You can bring anybody in, with the right instructions and credentials, and they can run the solution.
The solution's continuous protection is the best on the market. The ability to do the split-write, without any interruption to the production server, and the ability to roll back to any point in time you desire, are two really key features.

Four years ago when we did a PoC between two other vendors and Zerto, there were two features of Zerto that sold it, hands-down. One was the ease of creating protection groups, the ease with which our engineers could create protection, add virtual machines into the Zerto product, and get them under DR protection.
The second feature that sold us was the sub-second RPO. One of the things that made Zerto's product stand out from some of the more traditional solutions four years ago was its ability to maintain sub-second RPO over a group of machines, and that group of machines could be spread over multiple storage hardware.

We are doing continuous data protection. It works flawlessly. Our recovery points are measured in seconds. We have all these "baby snapshots" throughout the course of the day, so we can roll a VM back to any point in time, spin it up, and away we go. We're actively using that. It works great.

Zerto is very good at providing continuous data protection. For replication purposes, it's definitely better than Veeam. Veeam doesn't do as good a job as Zerto does when it comes to replication. The other alternative would be to just have backups somewhere. But even with backups, you lose a lot of time because you have to set it all up. With Zerto, you failover, you just click a couple of buttons and you run from the other location.

There wasn't anything in place that compares to what we're getting from Zerto. Before Zerto, we didn't have a proper disaster recovery program or application in place. We had a simple backup solution where we could back up our data every 24 hours. So we went from that to being able to recover full systems within a matter of minutes. With Zerto, if we do have an event or disaster, we know that we can recover from that much quicker than we were able to before.

The RTO and RPO are unparalleled. In the event you do have an issue, you can be back up and running (depending on the size of your infrastructure) within minutes. Your RTO can be 15 minutes and data loss be five minutes. I don't think that's matched by anybody else in the field.

The continuous data protection is great. We love it because I can see exactly how many seconds behind real-time we are, which is usually under 10 seconds. It keeps things up to date. We love the product.

Zerto's support for different hypervisors is a valuable feature because we have a mixed bag. We have VMware and we have Hyper-V. For us, that was extremely critical when we made the decision. We wanted a single tool that is able to replicate all our virtual servers. At this point, I think the only tool on the market that can do that on-premise is Zerto.
We own another solution called VMware Site Recovery Manager, SRM. We have licenses for our entire environment and we still decided not to use it. That's how big the difference was in the experience that Zerto provides.

Zerto Cons

The interface is the only thing that we've ever really had an issue with. It's gone through some revisions. The UI, it's not clunky, but it's not as streamlined as it could be. Some of the workflow things are not as nice as they could be.

The alerting doesn't quite give you the information about what exactly is going on when an issue comes up. We do get alerts inside of our vCenter, but it doesn't quite give you accurate information inside the plugin to be able to tell us what's going on without having to go into the actual Zerto application and figuring out what's causing the issue.

Another area for improvement I'd like to see is the tuning of the VRAs built into the GUI. It's a little cryptic. You really have to be a very technical engineer to get that deep into it. I'd like to see a little better interface that allows you to do that tuning yourself, rather than trying to get their engineer and your engineer together to do it.

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.

One thing I would like to see, and I know that this is on their roadmap, is the ability to use long-term storage in the cloud, like in Azure or AWS, making that even more seamless. Whether it's stored in glacier or on-prem, being able to retrieve that data in a quick manner would be helpful. They're just not there yet.

The improvement that I would like to see is a little bit easier product knowledge, things like that. It's getting a lot better than it was before because it's not as old of a product as Cisco, but if you look for something like Cisco routing and networking, you'll find millions of articles out there and it's everywhere.

Long-term retention of files is a function that isn't available yet that I'm looking forward to them providing. The long-term retention is the only other thing that I think needs improvement.

The alerting has room for improvement as it is the biggest pain point with the software. It is so bad. It is just general alerting on or off. There are so many emails all the time. You have no control over it, which is terrible. It is the worst part of the entire application. I have voiced this to Zerto hundreds of times for things like feature changes. Apparently, it's coming, but there is nothing concrete as to when you can do it.

For what we got it for, it does it great. I use a different solution for my disk-to-disk local backups to where I can have a local backup of files. I don't think Zerto does that well to where it keeps a memory of the files that are there. Basically, when something is deleted on Zerto, it gets deleted on the replicated version. So, some sort of snapshotting or something where I could have backups at different points in time of files would be a really helpful tool.

They definitely have room for improvement in a couple of areas. One is role-based access control. Right now, they don't have an identity source so they use the identity of the vCenter or the VMM. If they connected to an identity source like Active Directory and allowed for granular roles and permissions, that would be an improvement.
