Findings aus dem Backup-/Restore-Audit 2026-06-18 umgesetzt: - Dump-Frische als Prometheus-Metrik (homelab_borg_dump_present / homelab_borg_dump_age_seconds) im Host-Exporter; schliesst den Blindfleck, dass Borg weiterlaeuft und stale Dumps archiviert, ohne Job-Fehler. - Neue Alerts HomelabBorgDumpMissing / HomelabBorgDumpStale (critical) plus ALERT_RULES.md. - Freshness-Gate (.sh + .ps1) und H:-Nearline-Pull um n8n.sqlite.dump und postgresql17-globals.sql ergaenzt. - Critical-Container-Watch um mail-archiver, n8n, homeassistant, smarthome-mosquitto erweitert. - BACKUP_SCOPE: /mnt/user/projekte und sonstige User-Shares ausserhalb App-Scope als bewusste offene Operator-Entscheidung dokumentiert; Hermes-data-Pfad als geparkt klargestellt. - MASTER_TODO: Nearline-Pull-Ueberwachung, Host-Pull-Nachzug und projekte-Scope-Entscheidung aufgenommen. Enthaelt ausserdem die zuvor vorbereiteten Scope-Erweiterungen (nextcloud html+data, n8n, filebrowser, influxdb3) und Scope-Drift-/ Retention-/Compact-/Check-Alerts.

Borg dump scripts
These scripts are intended to run on the Unraid host before a Borg backup starts.
Current script
pre-backup-dumps.shgitea-bundle-mirror.sh
Output
Fresh dump artifacts are written to:
/mnt/user/backups/borg/dumps/latest
Fresh Gitea repository bundles are written to:
/mnt/user/backups/git-bundles/gitea
Borg UI should include /local/borg-dumps as a backup source.
The Gitea bundle target should also be part of the Borg scope, either through
the backups share or an explicit Borg source.
The dump set also includes unraid-flash-config.tar.gz, a host-generated
archive of /boot/config plus checksum and manifest. Treat this archive as
secret backup material.
Notes
- The script is written for host execution where
dockeris available. gitea-bundle-mirror.shadditionally expects host access to the Gitea bare repositories under/mnt/user/services/gitea/data/git/repositories.- It does not assume Backrest.
- It keeps only the latest dump set because Borg itself provides history.
Recommended automation path
The recommended automation path is:
- Unraid User Scripts on the host
- host-side schedule / cron
- Borg UI backup job afterwards
This is preferred over a Borg UI inline hook because the dump script expects:
- host access to
docker exec - host paths like
/mnt/user/... - direct write access to the dump target directory
Do not treat pre-backup-dumps.sh as a Borg UI inline script unless the architecture is deliberately changed later.
See USER_SCRIPTS_SETUP.md for the intended host-side rollout.
