Minecraft Java: Edition Realm worlds can be restored from an automatic or manual backup to undo unwanted changes or fix corrupted files. Restoring a world reverts all progress to what was captured in the save, including builds and items.
Restore a Realm world
- Launch Minecraft: Java Edition.
- Select Minecraft Realms.
- Select your Realm and select Configure.
- Select World Backups from the Worlds tab.
- Select Restore next to the version you want to load.
