Answer 1

The problem is the adb version of your PC. Using adb version 1.0.31 the backup/restore will be sucessfull.

If your device has an adb version prior to 1.0.31, then you must use an adb version of 1.0.31 on PC. Versions of adb 1.0.32+ broken the backwards compatibility. Source: Issue 208337
