These are deviations from the standard "DB dump first, file path second" strategy. Decide deliberately, do not silently extend.
### Nextcloud database
### Nextcloud
Recovery currently relies on the raw live DB path `/local/appdata/nextcloud/postgres`. This is inconsistent with the policy "Do not back up raw live database storage directories as the primary recovery artifact" stated below.
Open decision:
- Option A: extend `ops/borg-ui/scripts/pre-backup-dumps.sh` with a `nextcloud-postgres` dump and treat the raw path as transient.
- Option B: accept the raw path as a documented Nextcloud-specific exception.
Until decided, the raw path is what Borg sees today and is the only Nextcloud DB recovery surface.
### Nextcloud user data path is outside the borg-ui mount set
`/mnt/user/documents/nextcloud-data` is not mounted into `borg-ui` in `ops/borg-ui/docker-compose.yml`. Nextcloud user files are therefore not in the current Borg scope. Resolution requires a separate Compose change (add a read-only mount) and is not silently fixed in this scope document.
`pre-backup-dumps.sh` writes `nextcloud.dump` from `nextcloud-postgres`. Borg UI also mounts `/mnt/user/documents/nextcloud-data` read-only as `/local/nextcloud/data`, so database and user files are both inside scope after the Borg UI stack is recreated.
