"One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."
"The most important feature is that if I want to test the database at the disaster recovery site, I can take a snapshot, test it, and then revert it back to the original state without needing to restore the complete database from the primary data center to the disaster recovery."
"Backup and application continuity are most valuable."
"It's a very good solution if you want to protect your data across two data centers, or you have a middle man or many administrators who use these solutions for protecting their data. It's very reliable compared to other solutions that are most often not storage-based."
"The solution can scale as needed."
"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."
"In terms of the most valuable features, having the failover tests where you can see where your actual RTO and RPO would be is really nice, especially for the management level. I really liked the ease of when I need to do a file or folder restore off the cuff. Usually, it takes me less than five minutes to do it, including the mounting of the actual image. That was one thing with Unitrends, it was a similar process but if that backup had aged off of the system, then you had to go to the archive and you find the right disks, load them in, and then actually mount the image."
"In terms of continuous data protection, it's the best product that we've found that does this. It's not snapshot-based. It's continuous, so there are no specific points in time we have to worry about recovering to or from. It's pretty much any time, as long as it's within our replication window."
"We have seen ROI. The biggest way that we have seen it is in avoided downtime. We have had outages before, and we count downtime in terms of dollars spent. We have cut that down so dramatically, which provides us a very quick ROI. We have drastically reduced the amount of time it takes us to recover workloads, from an average of two hours to an average of 10 minutes."
"The file restoration is very helpful. They've improved it over the years to make it a lot more user-friendly and easy to do, which I appreciate. So, we use that quite a bit. The failover process is quite simple and intuitive. Even the configuration and setup are pretty easy to do. It is pretty easy to use. I've done the restoration of servers several times, not as a disaster. When an upgrade on a server goes wrong and it messes things up, I can just fail back to a previous version and try it again. So, that has been really helpful."
"If we had to deal with a ransomware event, Zerto would be one of the first things I would use, because it is going to be the fastest to restore data to a certain point. If there were a fire in our building, Zerto would be a big thing too, because we would shut down everything that's in our building. In most cases, Zerto is definitely one of the front lines. It's definitely going to be one of our prevalent DRBC layers of protection."
"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."
"Real-time or near real-time replication has been the most valuable feature. Our RTO is generally between six and eight seconds. The impact on our RTO is essential."
"We can spin up our environment in DR without affecting production, which is probably the biggest feature for us. We have the ability to do passive testing. We can even test scenarios, such as installing software or changing software. We can make modifications without affecting our production environment. So, the test functionality of being able to test the failover solution and being able to bring up our virtual machines in a test mode is the biggest benefit."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"The usage of block storage devices in the cloud or migration of a type of storage from one site to another site can be improved. Currently, we have to use multi-node to single node because of the lack of storage support on the Azure side. It did not really work. Our DBA had to spend a lot of time tweaking the Data Guard tools, or the underlying Oracle VMs, to make sure that Data Guard would run on top of different types of storage. So, if it can support transporting or getting from one type of storage to another type of storage in a different site or a different technology, it would be very helpful."
"Oracle could be improved by the ability to manage it on the cloud. This on-premises version is secure and reliable, but I'm sure that they will soon provide a cloud solution that will be even better. In one to two years, we will probably move to the cloud—we have already moved to the cloud with Microsoft Exchange, but our databases are still on-premises. I would prefer managing a cloud version of Oracle."
"The IP implementation and maintenance are a little bit hard to manage across Oracle solutions, including Oracle Data Guard."
"They may need to include the monitoring and the alerting part in Data Guard."
"Overall, there are some operational issues that need to be dealt with."
"It would be nice to have the option to do automatic failover, but right now the only option is manual."
"I don't have any input for improvement or a critical feature request at this moment. If anything, a lower price is always better."
"In general, the solution is pretty good, but because it is geared toward simplicity, sometimes, when things go wrong, the answer is not very detailed so that things can be solved quickly. If things do go wrong, it does require a little bit deeper troubleshooting to resolve the issues. That's the only area where improvement could occur. There should be a little bit more details about if things go wrong, how to remedy them."
"The monitoring and alerting functionality need to be improved."
"It took some time to get to know the solution in general, and exactly what functions each of the features is used for."
"I would like to see some graphical improvements in Zerto's interface. There's an option to export a list of all of our servers, but the information isn't presented the way we want. We want it in a specified sequence broken down by region, etc. We can't manipulate the data when we export it. Maybe they could change it to look more like an Excel sheet, and we can customize the graphics and data. We suggested these improvements to Zerto through their portal."
"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."
"Some of the integrations with our internal tools, in particular, company-specific ones, do not work. In cases like this, we have to ask for additional support."
