Format=Old_File
    Format=New_Tape

    Specifies whether the backed up or optimized .aij file was
    written in the old (disk-optimized) or the new (tape-optimized)
    format. The Format=Old_File qualifier is the default. You must
    specify the same Format qualifier that was used with the RMU
    Backup After_Journal command or the RMU Optimize After_Journal
    command. If your .aij file resides on disk, you should use the
    Format=Old_File qualifier.

    If you specified the Format=Old_File qualifier when you optimized
    or backed up the .aij file to tape, you must mount the backup
    media by using the DCL MOUNT command before you issue the RMU
    Recover command. Because the RMU Recover command will use RMS
    to read the tape, the tape must be mounted as an OpenVMS volume
    (that is, do not specify the /FOREIGN qualifier with the MOUNT
    command).

    If you specify the Format=New_Tape qualifier, you must mount the
    backup media by using the DCL MOUNT /FOREIGN command before you
    issue the RMU Recover command.

    Similarly, if you specify OpenVMS access (you do not specify the
    /FOREIGN qualifier on the DCL MOUNT command) although your .aij
    backup was created using the Format=New_Tape qualifier, you will
    receive an RMU-F-MOUNTFOR error.

    The following tape qualifiers have meaning only when used in
    conjunction with the Format=New_Tape qualifier:
