We performed a comparison between Oracle Data Guard and Zerto based on real PeerSpot user reviews.
Find out in this report how the two Backup and Recovery solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."
"We chose this solution for the availability of the databases. We can't afford Oracle Grid, this is the best solution if you want something similar that's less expensive."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"The solution is quite stable. We haven't experienced any bugs, glitches, or crashes. We find it to be quite reliable."
"Backup and application continuity are most valuable."
"Technical support is very good. If at any time we write a ticket, we get the appropriate answer on time."
"Oracle Data Guard has a nice feature called the DataGuard snapshot to open the solution in the read-write mode and make some changes to the database."
"The stability is great; there's very little downtime. I don't have to worry that there will be a surprise update to one of the ZVRAs or the host that I have to contend with. We're given plenty of notice to plan ahead for an update. As far as losing service and downtime, we haven't had that happen."
"Its ability to roll back if the VM or the server that you are recovering does not come up right is also valuable. You have the ability to roll back a few seconds or a few minutes. The rollback feature is great."
"Journaling is by far the most valuable feature. We have used it several times for customers who have gotten ransomware and had to do a rollback. Having the right time period was important. Some of them had their backups encrypted. So, they didn't encrypt the Zerto machine seven days previously, and we were able to bring that back up."
"This product is impressively easy to use. It's dummy-proof, once it's set up."
"Being hardware agnostic is nice in that we don't really need a 15 second recovery time. It's easy to use. It's always doing updates behind the scenes. These are the positive things. The setup is pretty easy. Building out the VPGs is pretty easy. And it works like it's supposed to."
"Zerto's most valuable features include its user-friendly interface, multi-tenancy capabilities, and near-zero downtime recovery."
"The ability to have a RPO of seconds has enabled us to restore data to just before an incident has occurred, which certainly saves a lot of time and money."
"I really like how you can test the failover as often as you need."
"Sometimes, the technical support team takes time to respond."
"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."
"It is a rather complex solution, so it could be more user-friendly."
"The implementation is complex for anyone who's jumping into it without any experience. It's all command-line driven implementations. For some, that's a turn-off."
"One thing that can be improved is the GUI. It would be good to have a very nice GUI to easily configure and administer, providing different presentations to the database administrator. The feature that can be included is the integration with third-party monitoring systems, that is, monitoring systems from other vendors, not only from Oracle."
"The database administration needs improvement. With Oracle, we have a lot of features for administrating data, but it might be too many. It needs to be simplified. It should be automated. Looking at Enterprise Manager, there are too many KPIs in place."
"Overall, there are some operational issues that need to be dealt with."
"When the data replicates into the standby database there is a possibility of having a microsecond amount of data loss. The data loss occurs when there is a network disconnection between the primary and secondary standby database located in the data centers or if there is a crash in the primary database."
"The setup process is time-consuming."
"The pricing could be a little bit lower."
"The RPO for our SQL server has room for improvement."
"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."
"We learned that we got a new account representative supporting our account. I found this out today. Apparently, this is something that they kicked off at the beginning of this year, but there has been a failure in communication in letting us know who is the proper channel for us to reach out to if we need assistance."
"You can create a VPG and put anywhere from one to 17 servers in that group. We build them one by one. If something changes in VMware, it would be nice to be able to go in and change that VPG, having it update without messing up. When you change them now, it only applies to the copies from the points when you changed it. I wish it would purge that older data from the past. Right now, we have to build a new VPG, which is not a big deal as it is just a few screens."
"The backup end of this solution could be improved. We tried using it as a full backup solution and it took way too long to complete at least one backup."
"I wish they would...develop their PowerShell module to be more robust. So instead of having to rely on the API to actually include a PowerShell command, it would let you create VPGs, delete VPGs, modify VPGs, etc. This would ease the automation effort of deployment and decommissioning and I'd really appreciate that."
