Synology is being removed as a host for the Anca/Elements archive
(770G). /srv/nfs/anca-elements on PVE becomes the source of truth;
sda /mnt/backup/anca-elements becomes the single-disk-failure mirror.
No offsite for this archive — by design.
- scripts/anca-elements-mirror.sh: rsync -rlt --delete -H, idempotent,
pushes anca_elements_mirror_last_{run_timestamp,status,bytes} to
Pushgateway, lockfile in /run, SIGTERM-safe (status=2 on abort).
- .service: oneshot, Nice=10, IOSchedulingClass=idle, 5h timeout.
- .timer: weekly Mon 04:00, Persistent=true, 15-min randomised delay.
Deployed to PVE host; timer enabled; initial 770G sync running in
background. Synology original to be deleted after first run completes
and parity is verified.
docs/architecture/backup-dr.md: documents Layer 3a + updated path
exclusion rationale (PVE is now upstream, not downstream).
