Regardless of how you specify data sets for backup, some data sets may be protected by the peer-to-peer remote copy (PPRC) function or by the extended remote copy (XRC) function. In either case, making backup copies is redundant and a waste of storage space. Use the ABACKUP SKIP(PPRC) command to direct ABACKUP to skip backing up any level 0 data sets that are totally contained on PPRC volumes. Use the ABACKUP SKIP(XRC) command to direct ABACKUP to skip backing up any level 0 data sets that are totally contained on XRC volumes. In addition, you can combine the parameters in the ABACKUP SKIP(PPRC XRC) command form.
