Notes for sysadmins

Migrations

Migrations run automatically by default.

# powersync.yaml

migrations:
    # Setting this to true will skip automatic migrations.
    # Migrations can be triggered externally by altering the container `command`.
    disable_auto_migration: true

MongoDB locks are used to ensure that migrations are only executed once in the case where multiple containers can be started simultaneously.

Backups

We recommend using git to backup your configuration files.

Your MongoDB database (for sync bucket storage) does not need to be backed up since it's easily recreated from Postgres.
