Multivolume save set

    When you save information with BACKUP Manager, the save set sometimes
    spans more than one tape volume, creating a multivolume save set.
    When this occurs, BACKUP Manager fits as much data as it can on the
    first volume and then dismounts the volume.

    Depending on whether you specified more than one drive or whether you
    are using a tape loader, BACKUP Manager then does the following:

    ·  If you specified only one drive in the Output save set device-name
       field on the Save Volume screen, and you are not using a tape
       loader or operator assistance, BACKUP Manager prompts you to remove
       the tape that is in the drive and insert another one.  After you
       insert and load the second volume (or after an operator fulfills the
       mount request), BACKUP Manager continues writing data to the second
       volume.

    ·  If you specified multiple drives, BACKUP Manager continues writing
       data to the second volume if:

         - The drive is loaded.
         - The drive is on line.
         - The drive has the correct volume label.

       BACKUP Manager unloads the first volume and resumes the operation
       on volume 2.

    ·  If you are using an automatic tape loader, BACKUP Manager
       continues writing data to the tape in the next slot, assuming the
       tape loader has an  adequate supply of correctly labeled tapes.
       BACKUP Manager rewinds  and unloads the first tape and resumes the
       operation on volume 2.

    As a safeguard against initializing or writing the wrong tape, BACKUP
    Manager compares the label that you specify in the Tape label(s)
    field to the label of the tape in the drive.
