The save file of a long-term archive for BS2000 files can be automatically duplicated if it is stored at storage level S2 and the long-term archive concerned was assigned a shadow archive. The automatic duplication mechanism must also be activated in the HSMS statement ARCHIVE-FILES. Here the value *ALLOWED must be specified for SHADOW-COPY in the OPERATION-CONTROL operand of the HSMS statement ARCHIVE-FILES (default setting).
The save file is copied into the assigned shadow archive at the end of the archival run. The copy in the shadow archive is given the same save version ID and save file ID as the original, i.e. it receives the same time stamp.
If the files are to be deleted after archival (DELETE-FILES=*YES), they are not deleted until the save file has been copied.
If a save file in a long-term archive is to be extended, the automatic duplication mechanism also attempts to extend the save file with the same SFID in the assigned shadow archive. If this save file does not exist, duplication (and possible deletion of the files) is not carried out and message HSM0318 is issued.
