add 3-2-1 backup pipeline: weekly PVC file copy, NFS mirror, pfsense, offsite sync - weekly-backup.sh: mounts LVM thin snapshots ro, rsyncs files to /mnt/backup/pvc-data with --link-dest versioning (4 weeks). Also mirrors NFS backup dirs from TrueNAS, backs up pfsense (config.xml + full tar), PVE host config, and prunes >7d snapshots. - offsite-sync-backup.sh: rsync --files-from manifest to Synology (no full dir walk). Monthly full --delete sync on 1st Sunday. After=weekly-backup.service dependency. - lvm-pvc-snapshot.timer: changed to daily 03:00 (was 2x daily) - Prometheus alerts: WeeklyBackupStale, WeeklyBackupFailing, PfsenseBackupStale, OffsiteBackupSyncStale, BackupDiskFull. LVMSnapshotStale threshold 24h→48h. 2026-04-06 14:53:28 +03:00			`[Unit]`
