CREATE
        Create a shadow copy.
        The user should set the desired context or options.
        The user can command BEGIN BACKUP to specify full backup.
        CREATE must be issued after at least one ADD VOLUME.
        It may be followed by EXEC to execute a duplication script for backup from the shadow copy.

        Here is an example sequence of commands to create a shadow copy for backup.
        It can be saved to file as script.dsh, and executed by typing DISKSHADOW /s script.dsh
        Assume:
            1) your system volume is c: and p: is an available drive letter.
            2) you have a backupscript.cmd in c:\ to
               perform the copy of shadow data p: -> your backup drive.

        #You can enter these commands manually or script them
        #Diskshadow script file
        SET CONTEXT PERSISTENT NOWRITERS
        SET METADATA example.cab
        SET VERBOSE ON
        BEGIN BACKUP
        ADD VOLUME C: ALIAS systemVolumeShadow

        CREATE

        EXPOSE %%systemVolumeShadow%% p:
        EXEC c:\backupscript.cmd
        END BACKUP
        #End of script

        You only need ADD and CREATE to create a simple shadow copy.
        This will not have context or option settings, and it will be a copy backup.
