VMS Help  —  BACKUP  Qualifiers  /IGNORE
       /IGNORE=option

    Specifies that a BACKUP save or copy operation will override
    restrictions placed on files or will not perform tape label
    processing checks.

                                   NOTE

       File system interlocks are expressly designed to prevent
       data corruptions, and to allow applications to detect and
       report data access conflicts.

       Use of the INTERLOCK keyword overrides these file data
       integrity interlocks. The data that BACKUP subsequently
       transfers can then contain corrupted data for open files.
       Also, all cases in which these data corruptions can occur
       in the data that BACKUP transfers are not reliably reported
       to you; in other words, silent data corruptions are possible
       within the transferred data.

    The /IGNORE= qualifier has the following options:

    ACCESSIBILITY    Processes files on a tape that is protected by
                     a volume accessibility character, or on a tape
                     created by HSC Backup. The option applies only
                     to tapes. It affects the first tape mounted and
                     all subsequent tapes in the save set.

    INTERLOCK        Processes files that otherwise could not be
                     processed due to file access conflicts. Use
                     this option to save or copy files currently open
                     for writing. You must have the user privilege
                     SYSPRV, a system UIC, or ownership of the volume
                     to use this option.

                     See the Note before this table for more
                     information about this keyword.

    LABEL_           Saves or copies the contents of files to the
    PROCESSING       specified magnetic tape volume regardless of
                     the information contained in the volume header
                     record. BACKUP does not verify the volume label
                     or expiration date before writing information to
                     the tape volume. Note that you cannot use this
                     option with the /EXACT_ORDER qualifier.

    LIMIT            Prevents the target device from inheriting the
                     volume expansion limit.

    NOBACKUP         Saves or copies both the file header record and
                     the contents of files marked with the NOBACKUP
                     flag by the /NOBACKUP qualifier of the DCL
                     command SET FILE. If you do not specify this
                     option, BACKUP saves only the file header record
                     of files marked with the NOBACKUP flag.
