o  To use the RMU Dump Backup_File command for a database, you
       must have the RMU$DUMP, RMU$BACKUP, or RMU$RESTORE privileges
       in the root file access control list (ACL) for the database or
       the OpenVMS BYPASS privilege.

       You must also have read access to the .rbf file.

    o  If you do not specify the Options qualifier or if you specify
       the Options=Normal qualifier, the backup file will be read,
       but dump output will not be generated. This is useful to
       verify the backup file integrity and to detect media errors.

    o  See the Oracle Rdb Guide to Database Maintenance for examples
       that show the RMU Dump Backup_File command.
