Microsoft Backup error 0x81000037 - no mounted volumes
When running Windows Backup I get after a while the "Failure to read shadow copy" with the above error. I followed instructions in http://support.microsoft.com/kb/973455 . I used the command window to find the Junction (parse) points. However, checking the properites none of the items in the generated list are listed as "Mounted Volumes"! So the entire solution just doesn't seem to apply. What can I do? Thanks.

Hi, The error you encounter is usually related to "reparse points" pointing to locations that can not be backed up for some reason (for example on fat32 volume). http://msdn.microsoft.com/en-us/library/aa365503(VS.85).aspx contains all info you need on reparse points. reparse points are in fact some kind of shortcut/link that redirects a folder. So the best advice would be to find out: a) wether you have fat32 formatted disks. If so, consider converting them to ntfs (using convert command) or not backing these files up using Windows Backup. b) Check your "Libraries" for included folders that do no longer exist. dir /al /s gives you list of "junctions" on the current folder and subfolders. Junctions are a very common kind of reparse point. You can use the information to find the "links" (reparse points) that cause the issue. Please note that not only "mounted volumes" can cause the issue. MCP/MCSA/MCTS/MCITP

This stupid backup program does not show which file/folder whatever generated the error. Any hints?
