About this project
What does Auto Backup add?







Automatic backups
- Set an interval and Auto Backup creates a backup in the background while you play — no interruptions.
- Optional backup right when you exit a world, so you always have a fresh save waiting.
- Old backups are pruned automatically once you hit your configured limit — favorites are never touched.
Manual backups, anywhere
- One click from the Backups screen, in-game or from the menu.
- Reach it from the main menu, the Select World screen, the pause menu while playing, or a configurable keybind — your pick.
Favorites
- Star a backup to protect it from both automatic cleanup and manual deletion. It's yours until you say otherwise.
Safe restores
- Restoring never overwrites your world. It creates a separate copy (
<world> backup <number>), so going back in time carries zero risk to your current save.
Built to feel vanilla
- Custom icons and screens styled to match Minecraft's own UI — tabs, buttons, and all.
- A quiet on-screen notification when a backup completes (toggleable).
