There might be some unwanted changes in the Registry Editor causing backup error code 0x8100002F to appear. For example, you may delete the

folder under the user profile by accident. In this case, it is a good choice to remove these keys which lack the
ProfileImagePath

Make sure to check all the folders under
ProfileList
and reboot your computer after modifying the registry.
