SYMPTOMS

Consider the following scenario:
  • You have a computer that is running Windows Server 2008.
  • Some Volume Shadow Copy Service (VSS) hardware providers are installed on the computer.
  • You use the Windows Server Backup tool or the Wbadmin.exe command-line tool to perform a backup on a computer.
In this scenario, the backup operation fails.

If you use the Wbadmin.exe command-line tool to perform the backup, you receive the following error message when this problem occurs:
Backup of volume VolumeLabel(X:) could not be completed. Error: The read from volume shadow copy on source failed.
Detailed Error: Invalid Function.

CAUSE

This problem occurs because the Windows Backup VSS Requestor incorrectly uses the VSS hardware provider instead of the VSS software provider that is provided by the system.
