A backup that includes an SMB remote volume is unsuccessful in Windows Server 2012

Applies to: Windows 8Windows 8 EnterpriseWindows 8 Pro


You run a backup on a computer that is running Windows Server 2012. To do this, you use a backup tool such as DiskShadow.exe to perform the backup for a local volume and for a server message block (SMB) file server remote volume. However, the backup is unsuccessful if the remote volume is added before the local volume, such as in a DiskShadow script.

For example, the backup is unsuccessful when you run a DiskShadow script that resembles the following:

#DiskShadow script file
set verbose on
Set Context Persistent
Set MetaData md.cab
begin backup
add volume \\Server\Share
add volume D:\


End backup
#End of script


This problem is caused by a mismatch that occurs when the Volume Shadow Copy Service (VSS) tries to find a volume device object that corresponds to the volumes that are listed in the DiskShadow script.
