consolidate offsite backup: inotify change tracking, deduplicate Synology paths [ci skip]
...
Architecture overhaul:
- Synology truenas/ renamed to nfs/, immich paths flattened to match source
- Created nfs-ssd/ on Synology for SSD data (thumbs, ML cache)
- Deleted pve-backup/nfs-mirror (53GB duplication eliminated)
- New inotifywait daemon (nfs-change-tracker.service) watches /srv/nfs + /srv/nfs-ssd
- offsite-sync Step 2: reads inotify change log, rsync --files-from only changed files
- weekly-backup: removed NFS mirror step entirely (NFS goes direct to Synology)
- Cleaned 9 orphaned LVs (101GB + 38 snapshots reclaimed from thin pool)
Performance: incremental sync completes in seconds (vs 30+ min with full rsync)

improve 3-2-1 backup: auto-discover dirs, Immich offsite sync, SQLite backup [ci skip]
...
- weekly-backup.sh: replace hardcoded BACKUP_DIRS with glob auto-discovery
(catches nextcloud-backup, council-complaints-backup, future dirs)
- weekly-backup.sh: add auto SQLite backup from PVC snapshots
(magic number check, ?mode=ro URI, fallback to raw copy)
- offsite-sync-backup.sh: add NFS media direct-to-Synology sync
(Immich, calibre, audiobookshelf — reuses existing TrueNAS Cloud Sync paths)
- Cleaned up 9 orphaned LVs + 38 snapshots on PVE host (101GB reclaimed)

fix offsite sync: use --chmod for Synology permission compatibility
...
Synology Administrator user can't create dirs with root-owned permissions
from PVC snapshots. Switch from -az to -rltz --chmod to set writable
permissions on destination. Also updated Cloud Sync Task 1 excludes
to prevent duplication of backup dirs on Synology.

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.
