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."Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."
"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."
"The most valuable aspect for me is undoubtedly the failover capability and the assurance of data safety provided by Oracle Data Guard."
"The most valuable feature is the application or promotional code used in the production protocol to transfer data to the secondary database, situated on the DR site."
"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."
"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."
"Oracle Data Guard is scalable. I rate it a ten out of ten."
"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"It is the backbone of our DR solution for critical databases that hold the data we can't afford to lose. It provided new opportunities to change how we approach disaster recovery."
"For us, the most valuable features are the quick upload time and how the sync works... We have VMware SRM and Veeam, and they have been pretty slow and sluggish."
"Failing over the VM without removing/touching the production VM from inventory is also an important feature."
"Zerto offered us massive time saving and consistency. We have a consistent outcome every time we complete conversions."
"It is very user-friendly. There is no wondering about what a feature does. It is easy to use."
"The one-to-many replication functionality is helpful. While we were protecting our VMs in Azure, we were able to use the one-to-many feature to also replicate the same VMs to our new data center, in preparation for data center migration."
"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."
"Zerto has improved our restoration time and made it easier to test software upgrades. It has simplified tasks like decommissioning a site and replicating virtual machines from one location to another."
"I think it would be great to have a graphical interface assistant (like DBCA, ASMCA, NETCA, etc.) for initial configuration, monitoring, configuring Oracle Data Guard Broker and all the Data Guard Broker commands, without needing Oracle Enterprise Manager Cloud Control installed."
"The deployment cost is expensive."
"The predominant issue lies in the communication link between the secondary and primary databases."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"It is a rather complex solution, so it could be more user-friendly."
"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."
"A significant improvement for Oracle Data Guard would be enabling the disaster recovery site to handle read and write operations, not just data storage."
"The IP implementation and maintenance are a little bit hard to manage across Oracle solutions, including Oracle Data Guard."
"One issue we've been having with Zerto lately is the ability to go into maintenance mode during vSphere upgrades. It doesn't have the hook into the lifecycle manager of the bump. During vCenter or ESXi upgrades, it causes VCF to fail its pre-checks because the machine doesn't power off and go into maintenance mode. It's been an issue since version 7.5 and it's impacting a basic automation function in vSphere."
"It has a file restore feature, which we have tried to use. We have had some issues with that, because the drives are compressed in our main file system. It is a Windows-based file server. So, it compresses the shares and can't restore those by default."
"It would be nice to have the option to do automatic failover, but right now the only option is manual."
"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 tech support on my latest issue wasn't so great. I had to figure a lot of stuff out myself. It could be that I had a Level 1 tech who was new or something, but it seemed like the tech was spitballing, which does not help me."
"With secure boot enabled, which is the case for newer systems, it is not easy to rotate passwords and we would have to reinstall the DRAs."
"Zerto generates many false positive alerts, which is annoying. I still have thousands of alerts in my inbox, and those are false alerts. When I check there's actually no problem."
"The interface is the only thing that we've ever really had an issue with. It's gone through some revisions. The UI, it's not clunky, but it's not as streamlined as it could be. Some of the workflow things are not as nice as they could be."
