Batch File to Mount the latest shadowcopy to a folder for access. Delete the link to unmount.

For example, the script below will mount the latest shadow copy to the local directory “C:\MyShadow” and then copy the “outlook.pst” located in user JDoe’s documents folder to a backup server. Once finished, the local directory which held the shadow copy location is removed to clean itself up.

    CALL MountLatestShadowCopy C:\MyShadow\
    XCOPY “C:\MyShadow\Users\JDoe\Documents\Outlook\outlook.pst” “\\BackupServer\MyFiles\”
    RMDIR C:\MyShadow
