Zerto Room for Improvement

David Riberdy
Enterprise Data Management Supervisor at Southern Farm Bureau Casualty Insurance Company
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. I like the fact that Zerto does what it does and it does it very well. I have had Zerto since version four, so the longterm retention and things like that were never a part of it at that point. I just like the fact that I can install it, I can protect my virtual machines, and I'm comfortable and confident that it's doing things correctly because of the amount of testing that we've done with it.

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 give you accurate information on the error message to be able to tell us what's going on without having to go actually login into Zerto to determine what's causing the issue. Another issue with the alerting is that it will pause a job. E.g., if we have something running from Massachusetts to Arizona, but a VM has been removed, updated or moved to a new location in vCenter. It literally pauses the VPG the VM resides in but will never give us a notification that it's been paused. Therefore, if we had an issue during the course of the day such as a power event and we needed to gain access to those VMs in some sort of catastrophe, we wouldn't be able to get access to them because that job was paused and were never notified about it being paused for whatever reason. It would therefore be a big problem if the VM was needed to be recovered and we didn't have those resources available. It would be great to get more precise alerting to be able to allow us to troubleshoot a bit better. Or have the application at least give us a heads up, "A VPG job has been paused." Right now, it's sort of a manual process that we have to monitor ourselves, which is not a great way to do things if you have a superior disaster recovery solution. View full review »

There's room for improvement with the GUI. The interface ends up coming down to a personal preference thing and where you like to see things. It's like getting into a new car. You have to relearn where the gauges are. I'd also like to see them go to an appliance-based solution, rather than our standing up a VM. While the GUI ends up depending on personal preference, the actual platform that the GUI is created on needs to go to an appliance base. 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. View full review »

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. If you're a small company with 50 VMs, this doesn't really become a problem for you. You don't have 1,000 blades and 1,000 of their VRAs running that you need to keep healthy. But once you get over a certain scale, it becomes a full-time job for someone to keep their products humming. 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. They desperately need to work self-healing into the core product. If a VRA has a problem, the product needs to be able to take some sort of measure to self-heal from that; to reassign protection. Right now it doesn't do anything in that self-healing area. View full review »

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. View full review »

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. It's prolific. So with Zerto, you have to find it within the Zerto application. Hopefully, as they grow, it'll be more out there on the net. Same thing with Microsoft. If you look for a problem with Microsoft, you're going to find millions of articles on it, maybe it's just because they've just been around for so long. I'm hoping that one day Zerto is just as prolific and can be found everywhere. View full review »

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. View full review »

While I am open to transitioning over to using Zerto for long-term retention, the problem is the alerting function in Zerto is very poor. That makes it a difficult use case to transition over. 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. View full review »

The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover. My other main inconvenience is fixed in version 8.5. That issue was moving virtual protection groups to other hosts, whenever a host goes into maintenance mode. That's actually automated in the newer version and I am looking forward to not having to do that any longer. View full review »

Senior Director - Information Technology at Revenew International
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. View full review »

Senior IT Engineer at a transportation company with 10,001+ employees
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. Another area of improvement is support for clusters. They have very limited support for Microsoft clustering. Also, integration with VMware could be improved. For example, when a VM is created in vCenter, it would be helpful to be able to identify the VM, by tags or any other means, as needing DR protection. And then Zerto should be able to automatically add the VM to a VPG. There is definitely room for improvement. But what they have implemented so far, works pretty well. View full review »
Network Administrator at a consultancy with 51-200 employees
The only time I ever have an issue is because there's a virtual server on each host in our environment. If I have to reboot a virtual machine host, I have issues with Zerto catching up afterward. That's about the only thing I would say needs improvement. Sometimes, when I have to do maintenance, Zerto takes a little bit to catch up. That's understandable. View full review »

Compared to other products, I would praise the intuitiveness of the product. But I think that can always be improved. The intuitiveness of the graphical user interface, while it is very solid and I don't have issues navigating it. I would say that it can always be improved. View full review »
Sr Director Security Operations at a tech services company with 10,001+ employees
There are two areas which I would recommend for improvement. One is when we are trying to upgrade any virtual machines, we have to stop the virtual machines that have been replicated in Zerto and then upgrade or update to the virtual machines onsite. Instead of having to do it manually, there should be some way of automating that particular function. And when it comes to AWS failover, the documentation has a lot of scope for improvement. It's come a long way since we implemented it, from the scantiness of documentation that was available to do a failover into AWS or recover from AWS, but they could still do a much better job of providing more details, how-to's, tutorials, etc. In terms of additional features that I would like to see included in the next releases, if they could provide us some kind of long-term storage option, that would be the best thing. Then it could be a storage and a failover solution combined into one. View full review »

Some of the features need improvement. One would be, as you're creating a Move group or a VPG, as they call it, it should either autosave or have the ability so that you can save it for coming back to later because if the setup times out, you lose all your work. That would be a nice improvement to have. View full review »

With the VPG (virtual protected group) it would be nice if you could pick individuals in the grouping instead of having to failover the whole group. Other than that, it's a pretty good product. View full review »
User at a financial services firm with 51-200 employees
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.

Some features are not up to what we need, although we have found alternatives and aren't really looking for Zerto to handle those items today. The setup process is time-consuming. View full review »
Mark McCully
Manager, Infrastructure at Vizient, Inc
I can't think of any major areas of improvement with Zerto. Make sure that they are building in cloud-friendly features in future releases because a lot of enterprises are starting to move workloads to the cloud and are seriously considering doing DR to the cloud as well. Our company may be moving in that direction also. I wouldn't mind seeing Zerto sold at a cheaper price point, although the cost is comparable to VMware SRM. View full review »
Rodney Carlson
System Analyst at a financial services firm with 201-500 employees
Certain areas were designed and work fine for VMware but are under development for Hyper-V. Eventually, all features will work for both platforms. Zerto support is very responsive when those questions arise. There is a comprehensive online training program which is a good start to using the application. But nothing can take the place of actually using the product in your own environment. The online search for solutions is very large. This is good, but also bad, as there are solutions present but you have to be diligent to find the answer you need. View full review »
There needs to be more flexibility in the licensing. I've mentioned to Zerto Management that I find the licensing at twenty-five VMs to be very restricting to an SME business, and could there be some flexibility here? Businesses like ours constantly change their IT due to the flexibility of Virtualisation and it would be great to get Zerto on board with that same flexibility. View full review »
I think Zerto could do better with size planning because it would be nice to analyze a server for a week and give an estimate on sizing the Journal. I find myself estimating too high. It would be nice if I had an option to dynamically restore to any host in a cluster. Right now, if we have multiple things happen and the main host is down it will not work. View full review »

I would like to see better notifications when the sync is off for an extended length of time. There is nothing worst then going to do an upgrade or test a restore and realizing some of the VPGs need to be fixed because their journal is too small causing bitmap syncing to be off. View full review »
Tim Kovars
Sr. Systems Engineer at Quarles & Brady LLP
Increased granularity in how long to keep the journal would be nice, currently you can only do hourly up to 1 day, after that it is only daily. The ability to test failover for a single VM in a VPG would be beneficial for testing purposes. Currently alerts come from both replication managers at times, creating a lot of alerts; reducing those would be good. View full review »
User at a wholesaler/distributor with 10,001+ employees
The number one thing we have found we would like changed so far is the cost per VM. It would be great to get that pricing reduced. The need for a VM to be spun up on every host is challenging. In our remote locations, it's not a big issue, but as we look to use that in our main data center where we have hundreds of hosts, it becomes more daunting. View full review »

The VSS agent setup and configuration does seem to be a bit clunky compared to the rest of the software. We have had issues with licensing, where the license we've been given by Zerto support doesn't include VSS replication, which was a pain at the time. View full review »
