The offsite Synology hit 97% — the Backup share grew +670G in a week, traced
to the 2026-05-26 change that began mirroring large regenerable services
offsite, plus an unbounded nextcloud.log bloating its backups to 87G.
- nfs-mirror: re-exclude ollama, prometheus-backup, audiblez, ebook2audiobook
(regenerable; live-only on sdc). Keep *-backup DB dumps (real safety copies).
- offsite-sync Step 2: nfs-ssd leg is now immich-only; ollama/llamacpp on the
SSD no longer ship offsite (re-pullable models).
- daily-backup: skip nextcloud/nextcloud-data-proxmox (orphaned pre-encryption
PV, still backed up weekly).
- nextcloud: cap+rotate the log (log_rotate_size=10MB); the dedicated backup
now excludes html/ (app code, from image), logs, and preview cache and keeps
only the latest copy (pvc-data holds version history) → <5G (was 87G).
- nextcloud: pin image to 32.0.9 in chart_values. A 2026-05-26 Keel bump moved
the live pod to 32.0.9 (data migrated to 32.0.9.2) but TF still defaulted to
32.0.3; reconciling that drift this session rolled a 32.0.3 pod that
CrashLooped on the downgrade. Pinning eliminates the drift.
Docs: backup-dr.md + infra CLAUDE.md updated (add nfs-mirror, new exclusions).
