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 Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Backup and application continuity are most valuable."
"One of the most valuable features is real-time replication. The version we're using is reliable and easy to deploy."
"The most important feature is that if I want to test the database at the disaster recovery site, I can take a snapshot, test it, and then revert it back to the original state without needing to restore the complete database from the primary data center to the disaster recovery."
"You can see how the logs are applied, check the apply time, and how far behind the standby is at any given time."
"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 most valuable feature is the flashback standby, which allows us to test without scrapping the database."
"The solution can scale as needed."
"It gives us a seamless, performant data center migration. When we were migrating between physical data centers, we did what normally would have been a 72-hour job in about 18 hours. A large part of that was thanks to Zerto being able to rate limit and throttle how much data was being sent or transfers were happening. Being able to script around it and create governors was important. We didn't have that previously. That is one big use case that has saved an immense amount of time and effort."
"The most valuable feature is Zerto's ability to precopy data to a remote destination prior to the actual live migration period. That saves us a lot of time and has been very helpful. For example, if we had migrations occurring in waves over a period of several weeks with a VPG or VPG setup of approximately 50 VMs, that is multiple gigabytes of data, even terabytes in many cases. Having that data already copied on the evening of the migration saves considerable hours of time. It easily saves us four to six hours a night."
"The Zerto university for training staff is very useful."
"I would give it an eight out of 10, if not a nine out of 10, when it comes to ease of use."
"The most valuable feature for us is accelerating cloud adoption, as it helps provide greater speed for disaster recovery. Ultimately, this saves us time, as well as resources."
"We have seen ROI. It reduced the time for failover and failback by 90%."
"When we use our VMware environment, sometimes the HP hardware is not compatible, and we start to lose data. I like that we can restore our whole application and public-facing system through Zerto."
"It works very well in terms of it providing continuous data protection. It does what it says it is going to do. We have been using it for several years, and once or twice, we had to recover a machine or files. It didn't have any problems in doing what it is supposed to be doing."
"We would like to be able to see the date time stamp when you execute DGMGRL commands."
"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."
"Overall, there are some operational issues that need to be dealt with."
"They may need to include the monitoring and the alerting part in Data Guard."
"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."
"It needs more documentation and automation features. I would like more documentation on designing an environment and network operations. On the automation side, I would like automation to clean up the environment in cases of a failed DR effort. An API interface to perform the DR exercise would also be nice."
"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."
"It has some quirks. We have quirks with appliances. Some things don't really work as expected, but it is minor."
"I wish Zerto had better file restoration capabilities. We have not been able to use that because of the limitations of Zerto's de-duplication technology."
"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."
"I am a little bit worried about how Zerto will work with large volumes of data, such as replication for big data and very large files."
"They could improve their online documentation."
"This solution could be improved if it met all the requirements that we look for including supporting multiple operating systems. We would prefer to use one solution for DR and backup."
