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."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."
"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."
"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."
"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."
"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."
"Snapshot and Data Guard Manager are awesome features."
"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."
"The migration and ease of use are valuable. It is easy to set up and easy to flip. We just need to click on Move."
"The ability to fully test your entire environment without actually performing a failover is invaluable."
"Zerto is fast to restore our mission-critical servers when needed."
"There are several valuable features because of the way we use it. The backup and restore features are definitely indispensable."
"The journaling is the most valuable aspect of the solution."
"Most of the time, this is at least a two person job. We used to have three people doing it. Previously, when we had a disaster recovery drill, the way it worked was 12 of us would show up in the office on a Friday night and work overnight from 12:00 AM on Friday night to 8:00 AM in the morning on Saturday. Then, three of us would be working for four hours out of those eight or nine hours just getting applications up and running in Arizona. Now, for the disaster recovery drill, I just stay onsite to help and assist anybody else as they need during that time frame and my work is done in about a 30-minute time frame. This is compared to the four or five hours it used to take for the three of us to do it."
"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."
"We've seen a massive benefit from using Zerto in terms of time savings and consistency. You see a consistent outcome every time you do the conversions. We're moving from one platform to another, but the payloads in what we're moving are different. We see consistent delivery."
"For every standby server you have, you must pay a licensing fee, which is the main disadvantage."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"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."
"Sometimes, the technical support team takes time to respond."
"The predominant issue lies in the communication link between the secondary and primary databases."
"The IP implementation and maintenance are a little bit hard to manage across Oracle solutions, including Oracle Data Guard."
"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."
"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."
"There are certain things about the user interface that could be a little bit more user-friendly."
"The time between releases is too long. Zerto doesn't seem to really keep up with the products with which they need to be compatible. For instance, the 9.5 updates 3 took about 90 days to come out after the latest version of vCenter 7.0 update 3 was released."
"When I have a technical question, it sometimes takes a while for tech support to respond."
"The technical support has room for improvement."
"If there is a mass of changes to a server, Zerto will restart the replication. It would be nice to know why that happens."
"Another thing that would help would be a recommender, or some type of tool that says, 'Hey, you're not conforming to best practices.' It would do a conformance or compliance check to tell you if your VPGs are set up according to best practices and whether your Zerto clusters are set up optimally. It would see if you have HA enabled and whether your alerting is turned on."
"The long-term recovery is a little bit weak in its granularity."
"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."
