Found while scoping the *arr media stack: there is currently no backup coverage for /mnt/user/appdata on Aegis. borgserver (old Unraid backup target) stopped accepting backups 2026-08-09 and was retired 2026-08-16; ccnet-pbs-backup-swarm-data only covers swarm CephFS. Adding a 6+ container *arr stack (plus revamped Lidarr) to this host makes appdata backup a prerequisite.

Near-term: install a Proxmox Backup client on Aegis and back /mnt/user/appdata (or at least the stack's appdata subtree) to luna-pbs. Data can land on the Unraid backup ZFS RAIDZ2 pool via PBS-back-to-Unraid for now.

Larger question: move Proxmox Backup Server itself back onto Unraid as a container (it was previously there). Evaluate storage target, retention, and how this interacts with the existing ccnet-pbs-backup-swarm-data flow and luna-pbs.

Blocks nothing hard for *arr phase 1 but should land before/alongside it. Related: *arr media stack design (in progress, not yet an issue).

Both halves resolved — closing.

Near-term (appdata coverage): delivered by PR #61 → ccnet-unraid-appdata-pbs-backup/ (Docker-packaged proxmox-backup-client on Aegis). Two layers into the aegis-unraid datastore, namespace copper/aegis-appdata, reusing the PVE encryption key:

daily primary (03:30) — crash-consistent appdata.pxar + bootconfig.pxar, --backup-id aegis
weekly cold (Sun 02:45) — CA Appdata Backup container-stopped archive, --backup-id aegis-appdata-cold

First backup GREEN and the restore drill PASSED 2026-08-29 (lidarr.db integrity_check ok, network.cfg byte-identical, --exclude /pbs-backup verified). Cron live in /etc/cron.d/root. Remaining: sanity-check the first aegis-appdata-cold snapshot after a Sunday (does not block Phase 1).

Larger question (PBS back onto Unraid): done, separately — luna-pbs was relocated from CT 356 to a KVM VM on Aegis (2026-08-29), see ccnet-luna-pbs-vm-runbook/. Same IP 10.10.10.250, same cert fingerprint, datastore aegis-unraid on the backup RAIDZ2 pool, NFS-exported host→VM over br0. Offsite sync (Aiden push, WI push per #62) intact.

Full build context: docs/arr-media-stack.md (Phase 0.5). A docs/homelab-build-history.md write-up folds into #58.
