backup: phase 1 + phase 2 scripts; daily script repaired and deployed Repairs the orphaned synapse-signing-key block at scripts/backup.sh lines 119-122 that was exiting the script under set -e before the Minecraft block could run, leaving 5 of the last 7 days without a world backup and zero usable snapshots after 7-day retention. Phase 1 (deployed today to /opt/docker/backup.sh on nullstone): - Repaired script — orphan block removed, MC arm wrapped so failures in one tar don't kill the run - tar exit code 1 ("file changed as we read it") now treated as success on the live MC world; spark profiler tmp file noise silenced via --ignore-failed-read --warning=no-file-changed - Plugin DBs (homestead, AuthMe, CoreProtect, LuckPerms) and configs now backed up alongside the world - Sentinel /opt/backups/.last-success stamped only when the world arm succeeds — gives outside monitors a single mtime to alert on - Manually verified end-to-end: 12G world tarball, 492M plugins, 279M dbs, 14 config files, sentinel updated. Pre-fix script saved at /opt/docker/backup.sh.bak-20260507-pre-phase1. Phase 2 (scripts in repo, deployment pending operator sudo): - scripts/restic-backup-playerdata.sh — Class A 5-min restic snapshots of playerdata/, stats/, advancements/, plugin DBs, LuckPerms; rcon save-all flush before snapshot; tag-scoped retention - scripts/restic-init.sh — one-time bootstrap (root-only) for /etc/mc-backup.{env,pw} + repo init at /home/user/restic/ - scripts/systemd/mc-backup-playerdata.{service,timer} — 5-min timer with hardening (ProtectSystem=strict, ReadOnlyPaths, etc) - docs/RUNBOOK-BACKUP-RESTORE.md updated with both phases' deployment steps and the operator-action checklist Off-host mirror to onyx (Phase 4) and class B/C/D world snapshots (Phase 3) are still TODO — see BACKUP-STRATEGY.md §11 phase plan. 2026-05-07 18:29:30 +01:00			`[Unit]`
