Before updating, leave yourself a traceable copy

The most worry-free approach before updating the game is to back up your world first. A normal update usually won’t touch your save, but a cross-version update can occasionally leave a world unable to open, or upgrade it to a new format you can’t roll back from—so keeping an original copy ahead of time is the safest bet.

There are two simple ways:

  1. Export to a .mcworld file—export your current world to a single .mcworld, saved on your device or to iCloud/cloud storage, and that’s your offline copy. Exporting is free in TopoBlocks.
  2. Make a snapshot—record a version point for the world with a timestamp, size, and source hash, making it easy to verify and roll back later. On-device manual snapshots are free, happen on your device by default, and aren’t uploaded.

For a more systematic look at the different ways to back up manually, see How to back up a Minecraft world.

Restore always creates a new copy and never overwrites the original

This is a hard line for TopoBlocks: restore always creates a new copy and never overwrites your current world. In other words, if your world acts up after an update, what you restore from the backup is a new world file—the original one, along with the backup, is still there and traceable. There’s no “restore and oops, it overwrote my current one too” scenario. For the boundaries of overwriting and restoring, see Does restoring a world overwrite the current save.

Should you use cloud backup

If you only update occasionally and exporting manually yourself is enough, there’s no need to pay at all—both export and on-device snapshots are free.

But if you want to skip the manual step every time and have your worlds automatically backed up to the cloud with version history preserved, you can subscribe to World Pro (¥22/month, 20GB), with pricing and quota as shown in the App. It suits players with many saves, frequent updates, who want to be able to roll back to an older version at any time. Both approaches create a new copy when you restore and never overwrite your current world. To learn how cloud backup works in detail, see Minecraft world cloud backup.
