Hi, you can use some external application that can backup/restore data of Android apps. I use Helium which is also recommended by NK, as I know.

There is also a full version of the app with some additional features, but even the free version should be enough for your purposes.

I have found only one issue: If you are restoring your saved data while not having enough internal memory space, the restoring process freezes sometimes instead of ending with an error message.
