When you perform a backup on a Windows 2008 Server-based computer that uses the Volume Shadow Copy Service (VSS) System Writer, the backup fails with error messages that reference nonexistent files.
This problem occurs if registry entries remain from a program that was uninstalled. If the program was not uninstalled successfully, the System Writer may list files to be backed up even though the files have been deleted. For example, McAfee VirusScan 8.5i is known to experience this problem.
