- Add new "Data Routing" flowchart up front showing which paths go
where (sda mirror vs Synology-direct vs not-backed-up).
- Overall Backup Flow: split Layer 2 into 2a (nfs-mirror daily 02:00)
and 2b (daily-backup 05:00); show nfs-mirror as an explicit
component; clarify Step 2 is immich-only direct + nfs-ssd.
- Weekly Backup Timeline → Daily Backup Timeline: actual schedule
(00:00 LVM, 00:15 PG, 00:45 MySQL, 02:00 nfs-mirror, 05:00 daily-
backup, 06:00 offsite-sync, 12:00 second LVM); explicit inotify
feeding Step 2.
- Physical Disk Layout: current capacity numbers + dual sdc→sda and
sdc→Synology arrows (immich-only) reflecting the two-leg design.
- Restore Decision Tree: refreshed age tiers (< 12h LVM, 12h-4w sda,
> 4w Synology) + dedicated branch for immich photos (which only
have an offsite copy).
