Can a lost Minecraft: PE world be retrieved?

Solution 1:

Restore on new iPad

If you are going to buy a new iPad, and backed up the stolen one you can easily restore the old backup and you will have the world back again. but you have to install all the apps (including minecraft again)

What does iTunes backup

• ...
• App Store app data (except the app itself, its tmp, and Caches folder)
• App settings, preferences, and data, including documents
• ...

I recommend this anyways because it will be identical to you old iPad.

Save the old backup to a external storage, because it might happen that itunes overwrites the backup and everything is lost.

Restore on PC
