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."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."
"It is a top-notch product, super stable, making it our go-to for internal operations."
"With Data Guard, Oracle guarantees zero data loss, providing peace of mind for organizations relying on their data for critical operations."
"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 solution has been stable so far."
"Oracle Data Guard is a free solution. When you apply for Enterprise Manager, it comes for free with the solution."
"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."
"The most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"Consistency Groups: If you replicate groups of VMs, then during failover, all of the VMs in groups are failed over to the exact same point in time."
"Zerto's ease of use is outstanding; it's easy to set up and has a clear interface and menus. The reporting, analytics, and online monitoring are also excellent."
"With Zerto, we were able to replicate our virtual servers to a remote DR site across a WAN connection."
"We've never had any major headaches with the virtual-protection groups. They seem to work exactly as they should. If there's ever an issue with replication, we know right away, so it's all been very reliable."
"It enables protection of a virtual workload to be done by the app, whether single or multi-tiered, with a boot time scheduler. It is pretty awesome."
"There are several valuable features because of the way we use it. The backup and restore features are definitely indispensable."
"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 own another solution called VMware Site Recovery Manager, SRM. We have licenses for our entire environment and we still decided not to use it. That's how big the difference was in the experience that Zerto provides."
"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."
"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."
"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."
"The only difficult part is the cost factor, licensing. Another area of improvement is support."
"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 initial setup is complex."
"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."
"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."
"Even though Zerto is for disaster recovery, it would be nice if it can also make backups."
"It would be nice if we were able to purchase single licenses for Zerto. As it is now, scaling requires that we purchase a multi-pack."
"I'm not sure if it has throttling, meaning, what's going over the wire and how we can throttle that to reduce the amount of data that's going across the bandwidth. I can't remember if that's something that's in this product. It might be in the more recent version."
"The replication appliances tend to have issues when they recover from being powered off when a host is in maintenance mode. Sometimes you have to do a manual task where you go in and detach hard disks that are no longer in use, to get the replication appliances to power back on. There are some improvements to be made around the way those recover."
"I would like to see some improvements with APIs going into the cloud so that they can more natively orchestrate the migration point-to-point without special hands-on configuration. Azure does some of that natively by having an agent on the VM, but Zerto could improve on its APIs into Azure or Google so that spinning up works more natively in that environment. It would make things smoother."
"If I were to nitpick, I would say that I wish I had a better account manager. Our sales guy has changed a couple of times. I would like a little more responsiveness from our account manager. I've had a couple of issues where getting in touch with him has been a little difficult, and I end up just going around him and dealing with support and support has handled it right away."
"Customer service and technical support need improvement."
"Improvements in Zerto's user interface and the addition of advanced features such as artificial intelligence or machine learning for predicting ransomware attacks and workload requirements would be beneficial."
