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 aspect for me is undoubtedly the failover capability and the assurance of data safety provided by Oracle Data Guard."
"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."
"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 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."
"We have not encountered any major challenges with replication. We were able to achieve near-real-time replication. Also, with the switchover failover, we were not getting any technical issues. It's a pretty stable product."
"The solution is quite stable. We haven't experienced any bugs, glitches, or crashes. We find it to be quite reliable."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"The granularity enables us to failover specific workloads instead of an all-or-nothing type of scenario, where you have to move your entire IP block and your data center, or you have to move large chunks of VMs. Those situations also make it prohibitive to test effectively."
"The most valuable features are the continuous streaming, that it takes very little CPU usage — it doesn't affect production — and the recovery time is very short."
"Our RPOs and RTOs are now more in line with our other critical systems."
"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."
"The quickness and efficiency of creating snapshots, on a real-time basis, is one of the most valuable features. Whenever changes are made on a server, Zerto starts taking snapshots right away and replicating them to the DR site. It's very effective and very quick."
"One of the most valuable features, something that I wasn't even anticipating, is the file backups. We weren't even considering Zerto to do restores, but it actually is able to do that. Eventually, we could just use this as our backup solution."
"I give Zerto's stability a nine out of ten."
"It does what it's purported to do, which is to provide continuous data protection. We have a five-second RPO. It's definitely doing its job."
"A significant improvement for Oracle Data Guard would be enabling the disaster recovery site to handle read and write operations, not just data storage."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"The product could improve its pricing."
"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."
"Overall, there are some operational issues that need to be dealt with."
"The only difficult part is the cost factor, licensing. Another area of improvement is support."
"The predominant issue lies in the communication link between the secondary and primary databases."
"This solution could be improved by including some sort of compression or de-duplication for the same type of files."
"Zerto could be considered as a backup product but this is not true. So if we could consolidate and use Zerto for disaster recovery as well as everyday backup and restore for situations where we need to recover something, that would be helpful. Anyway, we think that Zerto will win with no competition in the Disaster Recovery process, so we stay focused on this. Now we are testing version 10 which include real-time ransomware detection, a new Cyber Resilience Vault and enhanced cloud capabilities and security: we expect more from these features for superior hybrid cloud security."
"The licensing is confusing and complicated."
"The setup process is time-consuming."
"The overall management plan could improve. If something happens with the VM on the vSphere side, the error codes are pretty weak. If there was a way to click on something within the UI that takes us to a support page or article, that would be very beneficial."
"In Azure... We have to make sure that every resource group is tagged correctly, with the correct team and department because we have to bill them at the end of the month. The problem is that Zerto does not have that ability. When the product fails over or migrates a VM from on-prem, or even within Azure, to another site, it does not give you the option of selecting an existing resource group."
"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."
"It would be beneficial if Zerto also offered integration with other cloud management platforms, such as VMware Aria Automation."
