You can have BRMS record library objects and members or directories and files that could not be saved when running backup control groups. BRMS records the unsaved objects in a missed object policy which is nothing more than another backup control group containing one or more backup object lists or backup link lists containing these missed objects. You can then use the missed object policy to review which objects did not get saved, or to run the missed object policy in an attempt to re-save the missed objects.
To have BRMS record unsaved objects for all backup control groups, you can specify a missed object policy name on the Missed object policy prompt of the Backup policy. To have BRMS record unsaved objects for individual backup control groups, you can specify a missed object policy name on the Missed object policy prompt on specific backup control groups.

If the missed object policy does not exist when the backup control group runs, it will be created using the same attributes as the current backup control group. If the missed policy exists, you can also specify whether it is cleared of any existing missed objects using the Clear missed objects prompt.
Missed objects are recorded in backup object lists and/or backup link lists, and these lists are added to the missed object policy as backup items. The format of the backup lists name is Znnnnnnaaa where nnnnnn is the current job number and aaa is unique sequence identifer. These backup lists are created as needed depending on the auxiliary storage pool, object detail, and save-while-active attributes of the current backup items. These lists are deleted when a missed object policy is cleared. If you do not clear a missed object policy and use it for a subsequent backup, new lists are created and added as backup items to the missed object policy.
