Continuous=(n)
    Nocontinuous

    Specifies whether the .aij backup process operates continuously.
    You specify termination conditions by specifying one or both of
    the following:

    o  The Until qualifier

       Specifies the time and date to stop the continuous backup
       process.

    o  The value for n

       Specifies the number of iterations Oracle RMU should make
       through the set of active .aij files before terminating the
       backup operation.

    When you use the Continuous qualifier, you must use either the
    Until or the Interval qualifier or provide a value for n (or
    both) to specify when the backup process should stop. You can
    also stop the backup process by using the DCL STOP command when
    backing up to disk.

    If you specify the Continuous qualifier, Oracle Rdb does not
    terminate the backup process after truncating the current .aij
    file (when an extensible journal is used) or after switching to
    a new journal (when fixed-size journals are used). Instead, the
    backup process waits for the period of time that you specify in
    the argument to the Interval qualifier. After that time interval,
    the backup process tests to determine if the threshold has been
    reached (for an extensible journal) or if the journal is full
    (for fixed-size journals). It then performs backup operations
    as needed and then waits again until the next interval break,
    unless the number of iterations or the condition specified with
    the Until qualifier has been reached.

    If you specify the Continuous qualifier, the backup process
    occupies the terminal (that is, no system prompt occurs) until
    the process terminates. Therefore, you should usually enter the
    command through a batch process.

    If you specify the default, the Nocontinuous qualifier, the
    backup process stops as soon as it completely backs up the .aij
    file or files. The default value for the number of iterations (n)
    is 1.

    If you specify both the Until qualifier and the Continuous=n
    qualifier, the backup operation stops after whichever completes
    first. If you specify the Until=12:00 qualifier and the
    Continuous=5 qualifier, the backup operation terminates at 12:00
    even if only four iterations have completed. Likewise, if five
    iterations are completed prior to 12:00, the backup operation
    terminates after the five iterations are completed.

    The Continuous qualifier is not recommended when you are backing
    up to tape, particularly when the Format=New_Tape qualifier is
    used. If your tape operations complete successfully, you do not
    want the backup operation to continue in an infinite loop.

    Using the DCL STOP command to terminate a backup operation to
    tape might result in an incomplete or corrupt backup file.
    However, do not delete this backup file; it is extremely
    important that you preserve all .aij backup files, even
    those produced by failed or terminated backup processes. If
    the resultant .aij backup file is discarded, the next .aij
    backup file could contain a "gap" in transactions, so that no
    transactions would ever be rolled forward from that point on.
