The gpcr utility lets back up, and restore to a specific point in time, a cluster’s physical data. You may back up to four types of systems: Amazon S3, Posix-based systems (NFS), Google Cloud Platform, or a local filesystem. The utility supports both full and incremental backups, and allows you to specify named restore points that govern from what point in time data must be restored from the archived data.
It includes a number of commands:
| Command | Description |
|---|---|
| backup | Back up all of the segments of the database cluster |
| configure | Configure the database cluster for backup or restore |
| create-restore-point | Create an explicit restore point |
| expire | Designate a backup as expired and delete it, by setting the backup’s expiration date to now |
| help | Display command help |
| info | Retrieve information about all backups in the specified archive location |
| monitor | Monitor and report on backup progress |
| restore | Restore all database segments using the specified backup and restore point |
gpcr prints both verbose and debugging-related messages.
