Planning for a local site full IMS System Level Backup with forward recovery

You need to set up a local site full IMS System Level Backup with forward recovery.

About this task

Figure 1. IMS system configuration for a local site full IMS System Level Backup with forward recovery
This figure shows an IMS system that is configured to use data set isolation as a System Level Backup methodology. The upper boxes show the IMS source volumes separated into IMS recovery structure volumes and IMS application structure volumes and the lower box shows them recovered.

The following steps describe implementing a local site full System Level Backup with forward recovery:

Procedure

  1. The IMS system is discovered and analyzed so that the correct System Level Backup methodology can be chosen for the intended recovery needs.
  2. A System Level Backup Profile is created. During the profile creation process, DASD volumes used for the System Level Backup are selected. The target backup volumes can be selected from a range of target units or an SMS Storage Group.
  3. A System Level Backup is created using the information provided in the backup profile to drive a storage-based fast replication process. Backups that use the “full” option will back up all volumes of the IMS system (3a, 3b), while backups that use the “data only” option will back up the data volumes only (3b).
  4. The backup is recorded in the IMS Recovery Expert metadata repository. Recorded information includes: backup type, time, target volumes used, and data set name mappings for use in application-level recoveries.
  5. Online disk volumes can be archived to tape automatically after each System Level Backup or on demand using the System Restore and Offload ISPF menus.
