Accept_Label

    Specifies that RMU Backup should keep the current tape label it
    finds on a tape during a backup operation even if that label
    does not match the default label or that specified with the
    Label qualifier. Operator notification does not occur unless
    the tape's protection, owner, or expiration date prohibit writing
    to the tape. However, a message is logged (assuming logging is
    enabled) and written to the backup journal file (assuming you
    have specified the Journal qualifier) to indicate that a label is
    being preserved and which drive currently holds that tape.

    This qualifier is particularly useful when your backup operation
    employs numerous previously used (and thus labeled) tapes and
    you want to preserve the labels currently on the tapes. However,
    you are responsible for remembering the order in which tapes were
    written. For this reason, it is a good idea to use the Journal
    qualifier when you use the Accept_Label qualifier.

    If you do not specify this qualifier, the default behavior of RMU
    Backup is to notify the operator each time it finds a mismatch
    between the current label on the tape and the default label (or
    the label you specify with the Label qualifier).

    See the description of the Labels qualifier under this command
    for information on default labels. See How Tapes are Relabeled
    During a Backup Operation in the Usage_Notes help entry under
    this command for a summary of which labels are applied under a
    variety of circumstances.
