Empfehlungen (mehr Resilienz):
- Regelmäßig Restore testen (Stichprobe): DB-Import + Dateien entpacken + App-Start prüfen.
- Verschlüsselung: Archiv zusätzlich clientseitig verschlüsseln (z.B. age/gpg) bevor Upload.
- Immutable/Versioned Backup-Ziel (wenn möglich): Schutz vor Ransomware/Löschung.
- Monitoring/Alerting: systemd unit failure => Benachrichtigung.
- Snapshots (LVM/Btrfs/ZFS): Bei großen Datenmengen besser als rsync; reduziert Downtime für Nextcloud.
