The /GPT qualifier propagates the GPT.SYS file from the source
    disk to the destination disk. The /GPT=NONE qualifier does not
    propagate the GPT.SYS file from the source to the destination disk.
    By default, /GPT is enabled if GPT.SYS is located on the source
    disk.
    Note: If there is no GPT.SYS file on the source disk, the /GPT
    qualifier does not create a new GPT.SYS file in the destination
    disk. The /GPT and /GPT=NONE qualifiers can be used with the image
    restore or image copy operation only. Any attempt to use the /GPT
    and /GPT=NONE qualifiers with the save and non-image restore or
    non-image copy operation is ignored.
