Backup Missions

Backing up reports is performed in Control-D by a backup mission.

A backup mission backs up reports to tape or cartridge (as defined in the installation process).

The reports, already compressed on disk, are kept for the number of days defined in the backup mission (retention period). Each backup mission name indicates how many days the reports are to be kept. For example, BKP0031D represents a backup mission for reports that will be kept 31 days.

Several predefined backup missions with commonly used retention periods are provided in the Getting Started and production environment.

The backup process for a backup mission consists of four stages:

1. Build the list of backup candidates

   The list is built from those reports that were decollated with a DO BACKUP mission parameter that specified this backup mission name (in the decollating mission definition). You filled in this parameter in Chapter 3 of the Walkthrough.

2. Merge the backup candidate list with the backup JCL skeleton
3. Submit the backup job
4. Analyze the results of the backup job

The backup mission to be activated was predefined and ordered during the installation process. It is automatically ordered from this day forward. The only action you must perform is to add a prerequisite condition "trigger."

1. From the COMMAND field, type =7 and press Enter. The IOA Manual Conditions screen is displayed.

2. Position the cursor in the OPT field to the left of the OP-START-BACKUP- 007D. You are now going to add this prerequisite condition to the active missions environment in order to trigger the backup mission.

   Note: The suffix of the condition, 007D, indicates the number of days the reports are to be kept.

3. Type A and press Enter.

   The following message is displayed on the first line of the IOA Manual Conditions screen, to confirm that the condition has been added to the mission.

   CTM567I COND OP-START-BACKUP-007D ODATE date ADDED

   After adding the condition, track the backup mission in the Active Missions Environment screen.

4. From the COMMAND field, type =A and press Enter to view the Active Missions screen.
5. Type F BKP0007D in the COMMAND field and press Enter to find the backup mission in the list of missions with the help of the FIND command.

   The four stages mentioned earlier are now in process.

6. Press Enter periodically to display the current status. The backup mission enters a BACKUP-IN-PROCESS status.

   Note: The submitted backup job initiates a mount for a tape. Please notify the computer operator to mount the tape. When the backup mission status is ENDED OK, you may proceed to the next exercise.
