A. You can use diskshadow.exe, a new utility in Windows Server 2008, to create shadow copies and restore content from a shadow copy. Diskshadow.exe can create VSS snapshots, mount snapshots with a volume letter, and delete snapshots. The following script, written in the Diskshadow utility’s scripting syntax, creates a snapshot of the D drive, mounts the snapshot as drive X, calls a command file to copy files from X to a backup location, then unmounts the snapshot and deletes it.
#Make shadows persistent
SET CONTEXT PERSISTENT
SET VERBOSE ON
#Cab location for process
SET METADATA d:\temp\Backup.cab
#Alias volume with alias
ADD VOLUME D: ALIAS DVOL
#Expose the volume and run command file then unexpose
EXPOSE %DVOL% X:
#Delete the shadow copy
DELETE SHADOWS SET %VSS_SHADOW_SET%
The command file copycommands.cmd can contain any commands you need for copying your desired files from the shadow copy.
Save the script as vmbackups.dsh and run it using the command
diskshadow -s vmbackups.dsh
