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
