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.
Captures live config state of nullstone Purpur 1.21.11 server:
- docker-compose.yml (itzg/minecraft-server image, MODRINTH_PROJECTS + PLUGINS lists)
- All plugin configs under live-server/plugins/ (no DBs, no jars, no world data)
- Server core: bukkit.yml, spigot.yml, purpur.yml, paper-global.yml, paper-world-defaults.yml, server.properties
Excluded via .gitignore:
- World data (world/, world_nether/, world_the_end/, auth_limbo/)
- Sensitive: AuthMe DB (password hashes), Lands DB, CoreProtect DB, Essentials userdata
- Jars (auto-fetched), logs, caches, .paper-remapped
