Try to do backup on Windows 7 machine to network share on SBS2008. Was working fine. Now, recieve this error emssage "The backup was not successful. The error is: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up. Please check in the event logs for any relevant errors. (0x81000037)." Looked in event viewer and found this: "The backup operation that started at '‎2010‎-‎12‎-‎31T03:02:24.245000000Z' has failed with following error code '2155347999' (Windows Backup cannot find the shared protection point.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved." Please advise how to solve?

See the following troubleshooter: http://support.microsoft.com/kb/973455: Error code 0x81000037 If the reparse point points to a location that contains any compressed file format (multimedia files, .zip files, and so on), you receive an error message that resembles the following: 0x81000037: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up To work around this problem, remove this reparse point from the library, and then run the backup wizard again. To back up content for this reparse point, select the absolute path of this location from the Windows Backup configuration user interface. Note: This error may also occur if Microsoft Forefront Client Security reports a file as malware, and this file will be included in backups by Windows Backup. In this case, use Forefront Client Security to remove malware from your computer. Hope this helps.

I have this problem "0x81000037: Windows Backup failed while trying to read from the shadow copy on one of the volumes being backed up". I use Windows 7 Backup to automatically back my files up to a NAS daily. Can you please provide more detail about your answer "remove this reparse point from the library" ... specifically: what library -is this the volume being backed up or the backup itself? what utility do I use to remove the reparse point? Can you provide a step by step guide? Thanks RedRover7

I would also like a more detailed step by step guide because me and 95% of people having this problem are -not- technicians! (Sorry for bad English I am Dutch).

Hi, I also need more information on how to implement the solution you are offering. Where is the "reparse point". Do I simply delete it and rerun the backup? Thank you
