⁠Running

Backups are stored in the /backups directory, named as /backups/<database>/<database>-<timestamp>.sql. /backups should be mounted as a volume.

$ docker run -v /path/to/backups:/backups timheap/postgres-backups

⁠Configuring

Pass any of the standard PGUSER, PGPASSWORD, PGHOST, etc. environment variables to configure how pg_dump connects to your database. See the Postgres documentation⁠ for a full list. The default values will connect to a server named postgres on port 5432 using the postgres user with no password.

Set CRON_SCHEDULE to customise when the backup job runs. This defaults to @daily.

Set BACKUP_ON_START=1 to create a backup when the container starts, in addition to the cron job.

Set BACKUP_KEEP_DAYS to change the number of days of backups to keep. Defaults to 14 days of backups per database.
