Windows 7 backup failing with error 0x81000031
Windows 7 backup fails with the following error (German): Die Sicherung war nicht erfolgreich. Fehler: "Fehler beim Bestimmen des Bibliothekenspeicherorts eines der in die Scherung eingeschlossenen Benutzer durch die Windows-Sicherung. (0x81000031)" The short English version of this error message is: "cannot find library folders of this user". The backup error log under "C:\Windows\Logs\WindowsBackup" points to the same problem: Beim Sichern der Datei "C:\Users\sb.BUGFREE\Music" ist ein Problem aufgetreten. Fehler: (Das System kann die angegebene Datei nicht finden. (0x80070002)) Beim Sichern der Datei "C:\Users\sb.BUGFREE\Videos" ist ein Problem aufgetreten. Fehler: (Das System kann die angegebene Datei nicht finden. (0x80070002)) Short English version again: "Error backing up files. System cannot find the files in this path". Since I have relocated all my library folders to the root of drive D: the backup will never find any library on the C: drive. My profile folder on C: (which is "C:\Users\sb.BUGFREE") is empty except for the hidden folder "AppData". When configuring the Windows backup drive D: gets displayed as possible backup destination. I've set the actual backup destination to a network drive instead. Additionally I've set the backup to include the files chosen by Windows (recommended option). Putting all the pieces together I think that the Windows 7 backup has no support for relocated library folders. Since relocation of the libraries is a standard feature of Windows I think this case has just been overlooked in development of the backup. Perhaps someone from the Microsoft can confirm this as a bug. >> Steffen

I can not remove the device I see as causing the problem. It is a vestige of a one time attempt to use a Sony Camera jump drive. I now shows up as Drive Q:/ but will not allow me to delete it. How do I delete it?
