There are two types of restore: one is to restore backup data to an existing FEP cluster, and the other is to create a new FEP cluster and restore backup data.

The former retains the attributes of the FEP cluster, such as IP address and name, while the latter is created from scratch.

The restore process deploys a restore container. The restore container performs the pgBackRest restore operation from the backup data to be restored to the master server of the FEP cluster. After the data is restored to the master server, the FEP cluster is created by synchronizing the data to two replica servers.
