Backup Strategy for Game Servers: Snapshots, Incrementals, and Drills
Backups are only real if you can restore fast. Build a layered backup plan.
A backup is only useful if you can restore quickly under pressure.
Layered backups
Use daily full backups, hourly incrementals, and a pre-update snapshot.
Test your restore
Run a restore drill monthly. Document the exact steps and timing.
Keep an offsite copy
At least one backup should live outside the primary node.
Make backups a routine, not an emergency plan.
