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."One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"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."
"Data Guard also improved because customers with an active Data Guard license want to reduce the I/O in a production environment. Some application complaints to it for Oracle reporting purposes. It has a production environment that needs to be enhanced."
"Snapshot and Data Guard Manager are awesome features."
"The solution is quite stable. We haven't experienced any bugs, glitches, or crashes. We find it to be quite reliable."
"If you have a problem with your primary site and can't access your primary database, you can continue working with the database that you have as standby on the other site, by changing its role to primary."
"Another valuable feature is the possibility of backing up the database from the standby database instead of the primary database, to avoid backup process overhead in the primary system."
"Zerto is essential for protecting critical workloads. We don't protect all of our VMs, but some need to be recovered in a timely manner. The recovery time is almost immediate."
"The second feature that sold us was the sub-second RPO. One of the things that made Zerto's product stand out from some of the more traditional solutions four years ago was its ability to maintain sub-second RPO over a group of machines, and that group of machines could be spread over multiple storage hardware."
"The ability to test which virtual machines can be failed over to our DR site without interruption of our production environment."
"The UI is straightforward. It makes it very simple to group our resources and understand that our production workloads are covered because we can set them up as granular or as non-granular as we want."
"During a failover to a DR site, Zerto can automatically change the IP address of servers."
"Zerto is intuitive. We could set everything up in the environment within a day and a half and start migrating on the third day."
"It helps us keep our required retention period for specific documents and allows us to recover older documents if we have to compare and recreate those."
"Implementing this solution has given us sandboxing and the ability to move VMs."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"For Italian medium-sized companies, the main challenge lies in the cost associated with licenses."
"It is a very useful administrative IT tool. It saves on costs."
"The pricing of the solution is quite high. They should do what they can to bring it down so that it is more reasonable for customers like us."
"Oracle Data Guard is stable, but you need to keep monitoring the system all the time. You need to keep monitoring the archives."
"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."
"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."
"There is an issue with their application on ODG. There were a lot of edits in the logs. Sometimes, we only get a little cue from the Data Guard Broker logs if there's an issue."
"When we do failover and failback, it doesn't maintain some of the settings that it should and I don't really understand why that happens."
"It would be helpful if the reports can be generated periodically, on a schedule."
"It would be great if Zerto could automate replication more."
"Right now, if you have an error, it creates a link that takes you to a website to review information about the problem. It would be nice if Zerto could give you information within the app instead of referring you to a web application."
"The reporting could be improved in terms of the reports that you can show to auditors to prove that you have done the testing. I provide the reports that it generates now but, it would be great if, at the end of a DR test, it would generate a report of everything that Zerto did."
"There is a need to allow the source vCenter Inventory to be imported with a single click."
"The syncing of the replication needs improvement. My experience has been that, every once in a while, when you go to do a failover, it tells you it's not syncing. Then you have to troubleshoot and figure out why it's not fully synced up."
"The limitation with Zerto is that you're required to have one Zerto Manager per virtual center, and this means that you're only able to replicate one way. Technical support for this product was fantastic, before they were acquired by HP. You're now able to tell that the company is becoming too big, in terms of the support they provide."
