Back Up Unlinked Production Regions

If the region cannot be shut down for database backup, we recommend that you back up unlinked production regions as described here.

To back up unlinked production regions

1. Create a duplicate region with its own knowledge base.

   Important! Ensure that the databases of the duplicate region are not on the same DASD as the production region databases.

   Note: If the region supports shared system images, create the duplicate on a different system. You cannot link regions that support shared system images if those regions are on the same system.

2. Use the Link Region and Synchronize Database option (on the Multi-System Support Menu) to link the duplicate region to the production region.

   The databases of the production region are copied to the duplicate region.

3. (Optional) In the duplicate region, switch off console consolidation in the CCONSOLIDATN parameter group (shortcut /PARMS).
4. Load an empty system image with no EventView rule set.

   Note: The duplicate region does not perform any automation, it simply contains an up-to-date, mirror image of the production databases.

5. When the backup is required, stop the duplicate region and perform the backup to tape.

Note: Any database updates that occur while the duplicate region is stopped are held by the staging file. The updates are sent to the duplicate region when it is restarted.
