They could improve their online documentation. From a reliability perspective, the product is around seven. It's less reliable than, others for example. They have one limitation when they have a virtual protection group that does everything. From the ease of deployment perspective, it requires expertise and time. It's not very easy to do auto-tagging or to run multiple VPG genes at the same time. So, from multi-tenant or multi-complex scenarios such as using Zerto external products, such as firewalls, while their own product is good, it's part of a larger ecosystem, that still has a long way to go. The triggering of external products could be better. Combining a master runbook and not just a single VPG or splitting the protection group from the activation plan could be better. There will be a protection policy and activation policy as being done in other products. Better tagging and better multi-term support are needed. Currently, there is no tenant admin support, only global admin support. They should work at the tenant level instead of the global admin level. Right now it's an HPE product; they're no longer a startup. We are hoping that being bought by a major company will do good for them and they'll fix what needs to be fixed. There were very good products, to begin with, and HPE should work to make it even better.

The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that we're only able to replicate one way using this solution. Now, we are evaluating the clustering of Zerto with Microsoft clustering, so we can replicate both ways and both data centers, and have the management server in both data centers. Historically, Zerto has started going into the backup space, and that is when they lost focus on keeping their replication product good. Now, it seems they're finally leaving that backup space, and they're just sticking with replication, so in version 9, they have fixed all of my gripes about the product, e.g. they now support VMware tags, Windows bringing over the time on the target side, etc. All of these little things, they are all correcting, because they're now sticking with the replication product.

I would like to see them continuously improve Zerto's automated functions, such as putting hosts in maintenance mode within vSphere and not having to worry as much about how Zerto is going to react. Rather, Zerto should be able to handle putting various hosts, within either the source or destination side, into maintenance mode without having to worry about the vRA appliances. Sometimes, Zerto almost holds the vSphere environment hostage when it comes to taking certain actions. You really need to be cognizant about what you're about to do. They should further automate that and increase Zerto's ability to handle things like that in a very slick, automated way, without intervention. Zerto could also build more canned automation tools within their product, tools that automatically work with DNS updates to AWS or Azure. Maybe they could provide an area for scripting help or canned scripts, a community or a place where people could grab some scripting. Maybe they could reach into Citrix or F5 load balancer APIs. Also, if you have a host go wrong or you need to put one in maintenance in an emergency situation, especially on the source side, it can require you to fix Zerto and redeploy vRAs or redeploy the little appliances to the host that they're going to be on. Also, depending on what resources it has available, storage or vSphere-wise, I'd like to see it able to balance itself out within the virtual environment, with its storage usage on the destination side. I've only run into these things briefly, so I can't speak about them at the deepest technical level, but I have noticed that they're not as perfect as they could be.

I would like the ability to monitor the performance of some specific components. Right now we're having an issue with local and remote replications with some of the VPGs. Being able to look at individual VPG performance would be helpful. Another thing that would help would be a recommender, or some type of tool that says, "Hey, you're not conforming to best practices." It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on. Another area for improvement is alerts. We're getting so much noise right now in the 8.5 version. The problem is that we don't know which are the ones we need to act on. We don't know which ones are severe versus those that are informational or notice or debug. They have told us that when we upgrade to version 9 we'll be able to tune some of the alerts. That type of alert tuning, where we can get just the emergency and error alerts, would be helpful, while not necessarily tuning out the informational or notice or debug alerts. If alerts could be channeled to a syslog server where we could filter and see which alerts are the priority that would be an improvement. We have a network operation center and for us to operationalize this tool with them, we have to be able to deliver each alert along with an action plan for it. That way they can take the appropriate action if Zerto has some type of error. It would help if the alerts didn't just fall on our storage and data protection team. If we could transfer some knowledge and have other level-one teams look at some of the more basic Zerto alerts and try to resolve them, that would help.

The only issue I've ever had is that I wish that Zerto would work more closely with VMware. There have been a few times that Zerto has released an update but it wasn't supported with that version of VMware. I would like them to coordinate their updates with VMware's updates.

Cecil Maddison - PeerSpot reviewer

I know that Zerto can definitely improve some functionalities. I know some of the cloud pieces probably enable that. At the moment, it's doing what we want for us, and what it's doing for us right now is plenty. I can't say there's any improvement that I can see that needs to be done at the moment. I'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version.

Brad Wallick - PeerSpot reviewer

We did look at the long-term retention backup feature of Zerto a few years ago, and at that time, it was limited. I can't say what it is right now, but at the time, its functionality was limited in terms of basically where we could save it and how we could save it. Offsite air gapping our backups is important to us to help protect against ransomware, and at the time, it couldn't do that. That would be one area that would be important before we consider using the long-term retention again. I haven't looked at it recently, and they may have addressed this in the meantime, but if not, this would be an area of improvement.

It has some quirks. We have quirks with appliances. Some things don't really work as expected, but it is minor. It doesn't really affect the overall functionality.

The long-term recovery is a little bit weak in its granularity. Veeam is definitely superior in that aspect, as it's able to provide a granular view of files and databases, et cetera. However, it just kind of depends on what a business' recovery strategy is. From our business perspective, it's really not impactful to us because our recovery strategy is not based on individual files. But, I could definitely see it being a challenge if there is a very large instance of individual files, as a subset, that need to be recovered. I think that if somebody has terabytes of data then Zerto will recover it faster but navigating through the file explorer to get to files is not as easy with Zerto. One thing I don't like about the product, and I know this is where their claim to fame is, but whenever I have a VPG that has multiple virtual machines in it, and one virtual machine falls behind, it'll pause replication on everything else in that job until the one server catches up. The goal is to keep symmetric replication processing going, so the strategy makes sense, but for our business model, that doesn't really work and it has created a challenge where I have to manage each VM individually. It means that instead of having one job that would cover multiple servers, I just have one job to one server, which allows me to manage them individually.

reviewer1561263 - PeerSpot reviewer

Zerto should add the capability to replicate the same VM to multiple sites. The export capability should be improved so that it is more customizable in terms of what fields are exported and what the formatting is. I would like to see the ability for Zerto to handle physical servers, although that is becoming less important to us.

The onset of configuring an environment in the cloud is difficult and could be easier to do. When it's on-premises, it's a little bit easier because it's more of a controlled environment. It's a Windows operating system on a server and no matter what server you have, it's the same. However, when you are putting it on AWS, that's a different procedure than installing it on Azure, which is a different procedure than installing it on GCP, if they even support it. I'm not sure that they do. In any event, they could do a better job in how to build that out, in terms of getting the product configured in a cloud environment. There are some other things they can employ, in terms of the setup of the environment, that would make things a little less challenging. For example, you may need to have an Azure expert on the phone because you require some middleware expertise. This is something that Zerto knew about but maybe could have done a better job of implementing it in their product. Their long-term retention product has room for improvement, although that is something that they are currently working on.

The backup solution needs to be improved. From our perspective, Veeam and Zerto were competing products. They both do very unique things that they're very good at. For instance, Veeam can do replication well. However, it's really a backup product. Zerto can do backup, and yet it's really a disaster recovery product. It would be great if they could improve upon the backup functionality, or continually improve. We've seen some improvements, however, if they continue improving upon that it may eventually eliminate the need for the other product.

JON WATKINS - PeerSpot reviewer

It would be nice if we were able to purchase single licenses for Zerto. As it is now, scaling requires that we purchase a multi-pack. It hasn't been a big deal for us but it would still be helpful to have a little bit more granularity on the license count. The only timeline or limiting factor, in my opinion, is how long it takes to replicate. That all depends on your infrastructure, and we happen to be pretty fortunate that we have a nice pipe in between the two locations, between here and our DR site. If you don't have that limiting factor, it's just a matter of time. You just wait long enough for it to replicate over and then you're covered.

The documentation needs improvement in terms of the setup, getting enough detail, and getting that up to speed.

reviewer1565100 - PeerSpot reviewer

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.

Chris Slaby - PeerSpot reviewer
Top 20Real User

In terms of improvement, it would be helpful if the implementation team had a better best practices guide and made sure things like the journaling are very clearly understood. Speaking directly to our incident, we did have professional services guide us with the installation, setup, and configuration. At that time, there was no suggestion to have these appliances not joined to the domain or in a separate VLAN from our normal servers and everything. They are in a completely isolated network. The big thing was being domain-joined. They didn't necessarily give that guidance. In our particular situation, with our incident, had those not been domain-joined, we would have been in a much better place than what we ended up being.

Zerto has a really robust PowerShell and scripting that you can get lots of numbers out of but it's not exactly the easiest thing to do. Zerto has a few nice the pre-canned reports but there is a need for more. Unless you script something, it's difficult to go in, click a button, and see the information that you may be looking for. The problem with the backup product is that it's not very mature and you really need a specific use case to be able to use it effectively. It's hard to explain to our customers, especially our large customers, that the use case is so limited.

The monitoring and alerting functionality need to be improved. Ideally, the monitoring would include the option for more filters. For example, it would be helpful if we could filter by company name, as well as other attributes.

So far, it's been pretty good. I haven't had any issues. If I had to pick anything, it would be the documentation for upgrades. They need to make it easier for users to do upgrades without having to contact support, by providing better documentation for that.

In future releases, doing backups of the environment we need to be able to do hot backups of the database. Granular based backups of the OS, versus taking a backup of the entire VMDK. Currently, I don't think we are able to do all that right now. Having an agent-based backup is a benefit because you can back up the OS files, and If you have an agent for the database, you can do a hot backup of the database and restore it. You then would have the ability to do an entire VMDK backup. I don't think that they have the ability to do a hot backup of a database itself via an agent or something similar.

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.

Marian Lakov - PeerSpot reviewer

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.

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.

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.

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.

Dain Baltierra - PeerSpot reviewer
Top 20Real User

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.

Franklin  - PeerSpot reviewer

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.

Jason Moore - PeerSpot reviewer

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.

Paul Willett - PeerSpot reviewer
Top 20Real User

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.

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.

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.

Don Cargill - PeerSpot reviewer
Top 20Real User

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.

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 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.

Tim Lenz - PeerSpot reviewer

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.

reviewer1370727 - PeerSpot reviewer
Real User

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.

Rodney Carlson - PeerSpot reviewer

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.

reviewer1254672 - PeerSpot reviewer

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.

reviewer1246608 - PeerSpot reviewer

There are a couple of minor areas that could use improvement. The GUI could be streamlined a bit more to enhance the administrative tasks. I would also like to be able to throttle the email alerts, as sometimes they become a bit noisy, and get tough to keep on top of.

reviewer1245939 - PeerSpot reviewer

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.

Mark McCully - PeerSpot reviewer
Real User

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.

reviewer1226331 - PeerSpot reviewer
Real User

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.

Tim Lillis - PeerSpot reviewer
Real User

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.

reviewer1199877 - PeerSpot reviewer
Real User

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.

Tim Kovars - PeerSpot reviewer

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.

Stephen Fuller - PeerSpot reviewer

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.

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.

Mobile features are there only for visibility and not to take action. We would love to see the ability to perform actions through mobile apps. It would be helpful if the reports can be generated periodically, on a schedule.

Jay Stelmach - PeerSpot reviewer

The full site recovery is not up to SRM standards. Within a VPG, you can do great failover timing as well as ordering and scripting, but if your site contains many VPGs (as mine does), then it is difficult to manage failing over between sites, especially if you are at the site that was impacted.

Brian Munn - PeerSpot reviewer

I would like them to add a VM host replication option. Being able to replicate host configuration between sites would be a huge benefit.

Russell Lynch - PeerSpot reviewer

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.
