It can be used to restore a database to a specific location due to an application failure or to prepare a duplicate database for production.

Restore process can restore data by creating a CR (FEPRestore CR) for the restore as follows:

oc create -f [Custom Resource Files]

Example)

$oc create -f config/samples/postgres_v1_restore.yaml

There are two methods of restoring: restoring data to an existing FEPCluster or restoring data to a new FEPCluster.

When restoring to an existing FEPCluster, information such as the FEPCluster name, IP address, and various settings remain the same.

If you restore to a new FEPCluster, the FEPCluster name is the one you specified in CR and the new IP address is also given. If the setting value is not specified, the new cluster will inherit the settings from the restore source cluster, but you can change the settings to create a new cluster by specifying them in CR.
