Hey cybereagle,
Disable your security softwares and perform the backup to determine if it’s interferring with the backup process. Still no go? You may follow the steps mentioned below for further troubleshooting. Ensure that you enable the security softwares once you’re done with the troubleshooting.
This problem could also be due to one or more profiles under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\ProfileList with missing ProfileImagePath.
To check whether you have missing profiles:
Caution: The registry contains critical settings that are necessary for your system to function properly. Take extra caution while making changes. . For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article below:
Back up the registryhttp://windows.microsoft.com/en-US/windows7/Back-up-the-registry
1. Open regedit, navigate to the above registry key. (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList). Expand the list
2. Click on each of the profiles listed. The first 3 profiles should have ProfileImagePath value of
%SystemRoot%\System32\Config\SystemProfile,
%SystemRoot%\ServiceProfiles\LocalService, and
%SystemRoot%\ServiceProfiles\NetworkService
respectively.
3. Starting from the 4th profile, the ProfileImagePath should contain path to the user profiles on your machine, such as C:\users\Christine
4. If one or more of the profile has no profile image, then you have missing profiles.
To work around this, delete the profile in question:
1. First, export the ProfileList key for safekeeping. (Right click on the key, choose “Export”, and save it to the desktop.)
2. Right click on the profile in question, choose delete.
3. Try backup again.
