s8n-ru 0dad38e02e Initial commit: racked.ru Minecraft server config snapshot

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

Backup & restore

Schedule

Host cron, daily 02:00, 7-day retention. Script: scripts/backup.sh (deployed to /opt/docker/backup.sh on host). Output: /opt/backups/YYYYMMDD_HHMMSS/.

Backs up the whole nullstone Docker stack; the Minecraft block (lines 80-117 of backup.sh) handles MC.

Strategy

Server state	Backup type	Method
Running	World snapshot + configs	`docker exec` tars worlds inside container (consistent), then `docker cp` out. Configs tarred from host.
Stopped	Full archive	Single tar of `/opt/docker/minecraft/` (worlds + plugins + configs).

Manual backup

ssh user@192.168.0.100 /opt/docker/backup.sh

Manual archive (full server, while stopped)

ssh user@192.168.0.100 'cd /opt/docker/minecraft && docker compose down'
ssh user@192.168.0.100 'tar czf - -C /opt/docker minecraft' > minecraft-backup-$(date +%F).tar.gz
ssh user@192.168.0.100 'cd /opt/docker/minecraft && docker compose up -d'

Restore

# Stop running server
ssh user@192.168.0.100 'cd /opt/docker/minecraft && docker compose down'

# Move current dir aside
ssh user@192.168.0.100 'mv /opt/docker/minecraft /opt/docker/minecraft.broken'

# Extract backup
scp minecraft-backup-YYYY-MM-DD.tar.gz user@192.168.0.100:/tmp/
ssh user@192.168.0.100 'cd /opt/docker && tar xzf /tmp/minecraft-backup-YYYY-MM-DD.tar.gz'

# Re-apply perms (userns-remap)
ssh user@192.168.0.100 'chmod -R 777 /opt/docker/minecraft'

# Boot
ssh user@192.168.0.100 'cd /opt/docker/minecraft && docker compose up -d'

What's NOT in repo backups

Plugin jars: re-downloaded fresh on each boot via MODRINTH_PROJECTS / SPIGET_RESOURCES.
World data: only in /opt/backups/ archives, never committed to git (binary, large, frequently changing).
Player data (usercache.json, ops.json, whitelist.json): committed to repo as snapshots only; live state lives on host.
