Setting data set options

If you plan to allow IMS Recovery Expert to offload backups, you must set data set names and other specifications for the offloaded data sets.

1. On the Offload Options panel, specify Y in the appropriate backup type field (Local Primary, Local Backup, Recovery Site Primary, or Recovery Site Backup) and press Enter.
   Note: When you later edit a profile, specify U in the appropriate backup type field and press Enter.
