In the example system a full-volume dump is performed once a week on Sunday, starting between 3 a.m. and 4 a.m. and starting no new volumes after 5 a.m. All DFSMShsm-managed volumes are dumped every week. In addition, volumes in storage groups 1 and 2 are dumped to an extra copy for off-site storage every 14 days; volumes in storage groups 3 and 4 are dumped to an extra copy for off-site storage every 28 days. See Figure 1 for the complete set of commands that DFSMShsm uses to process a full-volume dump.
