On some Windows 10 systems, the Windows Backup utility fails to create backups on the attached USB / Backup device. If the backup is attempted with the Filr driver stopped, the backup succeeds without problem.


A fix for this issue is available in the Filr 2.0 Hot Patch 4 and Filr 3.1.1, available via the Novell Patch Finder.


Starting with Windows 10, Microsoft uses the USN Journal feature in the backup. When a backup is attempted, Windows attempts to read the USN journal information for each of the folders present in the user profile. Since Filr does not support the journal information, the backup is failing. This USN journal was present in earlier versions of Windows but it was not used during backups.
