- Add libreportal.backup.db labels to the MariaDB/Postgres apps (nextcloud,
owncloud, bookstack, mastodon, invidious) so they back up live + consistent.
- If a declared dump cannot be taken (DB down, wrong path), the backup falls
back to stop-snapshot-start for that run instead of snapshotting torn data —
a misconfiguration degrades to 'safe with downtime', never to 'unsafe'.
