The FEP backup container is deployed as a sidecar to each FEP server POD. The backup is performed at scheduled time set by the user (like crontab). The FEP backup container determines if the FEP server in the POD is a master or replica, and will perform the backup process only on the master POD. The volume storing backup and archived WAL files must be on a shared storage such as NFS or AWS S3.

Backup and WAL archiving is accomplished with pgBackRest.
