You use the engine-backup tool to take regular backups of the Oracle Linux Virtualization Manager. The tool backs up the engine database and configuration files into a single file and can be run without interrupting the ovirt-engine service.

You also use the engine-backup tool to restore a backup. However, the steps you need to take can be more involved depending on your restoration destination. For example, the engine-backup tool can be used to restore backups to fresh installations of Oracle Linux Virtualization Manager, on top of existing installations of Oracle Linux Virtualization Manager, and using local or remote databases.

If you restore a backup to a fresh installation of Oracle Linux Virtualization Manager, you do not run the engine-setup command to configure the Manager.

You can also use data center recovery if the data in your primary data domain gets corrupted. This enables you to replace the primary data domain of a data center with a new primary data domain.

Reinitializing a data center enables you to restore all other resources associated with the data center, including clusters, hosts, and storage domains. You can import any backup or exported virtual machines or templates into the new primary data domain.
