Format=Old_File
    Format=New_Tape

    Specifies the format in which the backup file is to be written.
    Oracle Corporation recommends that you specify the Format=Old_
    File qualifier (or accept the default) when you back up your .aij
    file to disk and that you specify the Format=New_Tape qualifier
    when you back up your .aij file to tape.

    If you specify the default, the Format=Old_File qualifier, the
    RMU Backup command writes the file in a format that is optimized
    for a file structured disk. If you specify the Format=New_Tape
    qualifier, the Oracle RMU command writes the file in a format
    that is optimized for tape storage, including ANSI/ISO labeling
    and end-to-end error detection and correction. When you specify
    the Format=New_Tape qualifier and back up the .aij file to tape,
    you must mount the backup media by using the DCL MOUNT command
    before you issue the RMU Backup After_Journal command. The tape
    must be mounted as a FOREIGN volume. If you mount the tape as an
    OpenVMS volume (that is, you do not mount it as a FOREIGN volume)
    and you specify the Format=New_Tape qualifier, you receive an
    RMU-F-MOUNTFOR error.

    When you back up your .aij file to tape and specify the
    Format=New_Tape qualifier you can create a backup copy of the
    database (using the RMU Backup command) and a backup of the
    .aij file (using the RMU Backup After_Journal command) without
    dismounting your tape.

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

       Active_IO
       Block_Size
       Crc
       Density
       Group_Size
       Label
       Owner
       Protection
       Rewind
       Tape_Expiration

    The Format=New_Tape and the Noquiet_Point qualifiers cannot be
    used on the same Oracle RMU command line. See the Usage Notes
    Help entry for an explanation.

    The default file specification, when you specify the Format=New_
    Tape qualifier is .aij_rbf. The default file specification, when
    you specify the Format=Old_File qualifier is .aij.

    Although Oracle Corporation recommends that you specify the
    Format=New_Tape qualifier for .aij backup operations to tape
    and the Format=Old_File qualifier for .aij backup operations to
    disk, Oracle RMU does not enforce this recommendation. This is to
    provide compatibility with prior versions of Oracle Rdb. See the
    Usage Notes Help entry for issues and problems you can encounter
    when you do not follow this recommendation.
