Create a panel backup before changing the world slot, difficulty, seed or server files. The Core Keeper package exposes both backup and restore actions, and a live restore test recovered the exact original ServerConfig.json.
- Stop the server and click Backup Server.
- Confirm the action and wait for the task to finish.
To restore, keep the server stopped, open Restore Backup, choose the required dated archive, tick Are you sure? and click Execute.
Wait for restoration to finish, start the server and confirm the expected world loads before deleting any newer backup.
