05 / World management
World backups and updates
Make a full backup before moving your adventure, then check the new build's world rules.
Back up before updating
Action diagram
Close the game and server
Fully close your single-player game or stop your private server.
Copy to a separate location
Copy the entire world folder to another location and keep the previous mod JAR. Do not back up only selected files.
Test the backup copy
Install the update in a new profile and test it with a copy of the backup first. Other players must use the same build.
Apply rules to an existing world
The world owner or server administrator applies rules to an existing world that has no Nuram rules yet. Earlier Nuram save formats are not converted automatically. If data is quarantined, keep the original files and use a complete backup with its matching build, or start a new world.
Action diagram
Inspect the current state
Run /nuram rules inspect and note the current status and revision.
Use the inspected revision
Confirm that the backup is complete, then run /nuram rules apply 1 <revision> backup-confirmed. Replace <revision> with the actual number from the previous step.
Check READY
Run inspect again and confirm READY before playing. If the state has changed, check the latest revision again.
Here, 1 is the world rules version, which is separate from protocol version 9. New worlds initialize automatically.
Restore a previous version
Close the game or server, then restore both the previous JAR and the complete world backup from that time. Replacing only the JAR in an updated world is not a safe rollback.
Game version: 0.1.2
