Each time an archive or backup run is made, another archive tape is created (or an archive data set on disk). As time passes, consolidate archive tapes (or move the archives on disk off to tape) and remove the expired data sets.
CA Disk provides an archive MERGE function that successively processes each archive tape volume, or an archive data set on disk, as input. It copies and distributes only the unexpired data sets.
The simple JCL merges data from FILES data set to new volumes.
