Backing up and restoring the DB

Users can configure backups of PostgreSQL (DBaaS) through the Samsung Cloud Platform Console and restore from the backed‑up files.

Backing up PostgreSQL(DBaaS)

PostgreSQL (DBaaS) provides a data backup feature based on its own backup commands. Additionally, it provides an optimized backup environment for data protection and management through backup history verification and backup file deletion features.

PostgreSQL(DBaaS) Recover

If a failure or data loss requires restoration from a backup file, you can recover using the recovery feature based on a specific point in time. When performing a PostgreSQL (DBaaS) recovery, a new server is created with the OS image from the initial provisioning point, the database is installed with the version from the backup point, and the recovery proceeds with the database’s configuration information and data.
