Duplicating Saved Items

Beginning with V5R4M0, BRMS allows you to mark saved items for duplication as an alternative to marking volumes. If your daily saves are appended to active volumes and then duplicated, this allows you to only duplicate the appended data to the output volume rather than having to reduplicate the entire volume.

Note:
This duplication method is not supported for optical media.

You can mark saved items for duplication by specifying *YES for the Mark history for duplication (MARKHST) parameter on any of the BRMS save commands, or using a media policy for the save which has *YES specified for the Mark history for duplication prompt.

You can have BRMS search for marked history items when running duplication by specifying *SCHHST for the From volume identifier (VOL) parameter of the Duplicate Media using BRM (DUPMEDBRM) command. Optionally , you can use the Mark history for duplication (MARKHST) parameter on the DUPMEDBRM command to specify whether the duplicated history items are to be remarked for a subsequent duplication.

You can use the Work with Media Information (WRKMEDIBRM) command and the Duplication view of the Work with Media Information display to view the marked saved items, or use options 18 and 19 to mark and unmark specific saved items. To do so, you can follow these steps:

  1. Run the WRKMEDIBRM command from a command line.
  2. Press F11 twice to get to the Duplication view of the Work with Media Information display.
