Why It Matters
Disk failure, human error, or attacks can wipe months of gameplay in seconds.
The 3-2-1 Backup Rule:
- 3 copies (original + 2 backups)
- 2 different media types (local disk + cloud)
- 1 off-site copy (e.g., Backblaze, AWS S3)
Automate with cron:
0 2 * * * tar -czf /backups/mc_$(date +\%F).tar.gz /opt/mc/world && rclone copy /backups/mc remote:game-backups
Tip: Test your restore process monthly!
