No_Read_Only Allows you to specify that you do not want any of the read-only storage areas in your database to be backed up when you back up the database. If you do not specify the No_Read_Only qualifier, any read-only storage area not specified with the Exclude qualifier will be included in the backup file. The No_Read_Only qualifier allows you to back up a database with many read-only storage areas without having to type a long list of read-only storage area names with the Exclude qualifier. If you specify the No_Read_Only qualifier, read-only storage areas are not backed up even if they are explicitly listed by the Include qualifier. There is no Read_Only qualifier.
