What Are Backup Missions?

Backup missions are the basic mechanism used by Control-D for backing up CDAM datasets to tape or cartridge. A backup mission makes a copy of the CDAM datasets onto tape. It does not delete the CDAM dataset from the disk.

Each backup mission archives the CDAM datasets for a specific period of time. You tell Control-D which backup mission should back up which reports. You do this in the report decollating mission definitions using DO BACKUP parameter. The backup mission name supplied is the mission that will back up all entries in the Active User Report List file marked with its name.

Report Decollating Mission Parameters Example

   ON CLASS      = T         EXTWTR               DEST          FORM           

   PRT COPIES    LVL    USER                      DEST          MAX COPIES     

       PRINT/CDAM PARMS =                                                      

   WHEN LINE       -       COL       -       PRINT   REF NXT   CT     AND/OR   

        STRING =                                                               

     DO USER     = *                     LVL    LINE 006 COL 016 - 019 S A T   

                                         SYNONYM =       CONCAT =            

     DO NAME     = PURCHASE ORD REPORT          LINE     COL     -            

     DO BACKUP   = BKP0031D                                                   

     DO                                                                        

You can define multiple backup missions that will back up reports for different lengths of time. For example, back up all the Accounts reports for a year, back up the JCL MSGCLASS output for a month, and back up all the Audit reports for seven years.

Each backup mission uses a separate tape, so if you run three backup missions every day, a minimum of three tapes will be used every day.
