The problem is probably that mettska's backup is from 2.0.1, and from 2.0.2 onwards Jolla changed the way the backup system works, and thought it was a good idea to make it completely incompatible with the old way.

mettska, I think the way to solve this would be to do another factory reset, then restore the backup on Sailfish 1.x–2.0.1 before updating to 2.0.2 and above.
