To Back Up a Model

Follow these steps:

1. Access the Main Menu.
2. Select options 1.3.10.1. Press Enter. The Create Sequential Backup of Model panel displays.
3. Specify the name of the model you want to back up, as the name exists on the Host Encyclopedia.
4. Enter a fully qualified backup data set name. Use quotation marks.

   Note: Quotation marks create the data set name as entered. Without quotation marks, the data set name created is the one entered plus a system prefix and system suffix.

5. Enter a cleanup value.

   The cleanup value specifies the number of backup generations kept. Earlier generations are deleted.

   For example, to keep the current backup and the one before it, specify 2. The Backup utility:

   • Creates a new backup (the 0 generation)
   • Keeps the previous backup (the -1 generation)
   • Deletes the earliest backup (in this case, the -2 generation).

   If the cleanup value is zero, the utility keeps all backups.

6. Press Enter. A panel to Update JCL displays. Specify or edit the job card if necessary. Online Help contains suggested parameters for memory size and time. Press Enter. The JCL for the archive program displays below the JOB card.
