I recently installed windows 7 on my new Windows 8.1 computer and then made a system image and set up a regular backup schedule using Windows backup in control panel. The system image was created with no problem but I ran into a problem with the file backup. I get this error message when windows attempts to backup my files "Backup encountered a problem while backing up file c:\widows\system32\config\systemprofile\Background. Error:(The system cannot find the file specified." Can anyone tell me what this means and how to fix it; or even if it is something that requires fixing?
