Owner=user-id

    Specifies the owner of the tape volume set. The owner is the
    user who will be permitted to restore the database. The user-
    id parameter must be one of the following types of OpenVMS
    identifier:

    o  A user identification code (UIC) in [group-name,member-name]
       alphanumeric format

    o  A UIC in [group-number,member-number] numeric format

    o  A general identifier, such as SECRETARIES

    o  A system-defined identifier, such as DIALUP

    The Owner qualifier cannot be used with a backup operation to
    disk. When used with tapes, the Owner qualifier applies to
    all continuation volumes. Unless the Rewind qualifier is also
    specified, the Owner qualifier is not applied to the first
    volume. If the Rewind qualifier is not specified, the backup
    operation appends the file to a previously labeled tape, so
    the first volume can have a protection different from the
    continuation volumes.
