# Backup

Backing up the BASE_DIR (default: /srv) should in theory be sufficient.

## Database Backup

As database servers like PostgreSQL might not play nicely with taking a backup of their data folders while running, it's advised to first dump the database and only include the dump in the backup.

Therefore, all database containers SHOULD follow a common naming folder scheme.

### postgres

**Scheme:** $BASE_DIR/{service}/psql

**Task:** `task srv:psql-dump -- {service}`

**Dump:** /tmp/container-server/{service}.sql

### {to be extended}

**Scheme:** $BASE_DIR/{service}/tbd

**Task:** `task srv:tbd-dump -- {service}`

**Dump:** /tmp/container-server/{service}.tbd
