Rewind
    Norewind

    Specifies that the magnetic tape that contains the backup file
    will be rewound before processing begins. The tape is searched
    for the backup file starting at the beginning-of-tape (BOT). The
    Norewind qualifier is the default and causes a search for the
    backup file to be started at the current tape position.

    The Rewind and Norewind qualifiers are applicable only to tape
    devices.
