Please share with the community what you think needs improvement with Zerto.
What are its weaknesses? What would you like to see changed in a future version?
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
The email alerts can be excessive, so better control over frequency or resolution may be a worthwhile improvement.
The backup functions are in need of improvement.
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.
It's coming, but I want to do my backups from my DR side without impacting my production side. This is supposed to come out in v7.0.
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.
I would like them to add a VM host replication option. Being able to replicate host configuration between sites would be a huge benefit.
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.
