Managing availability with DFSMSdss

One of the major functions of DFSMSdss is the backup and recovery of data. Using the DUMP and RESTORE commands, you can backup and recover data sets, z/OS UNIX files, and volumes. You can also use the DUMP and RESTORE commands on ranges of tracks. However, this is usually done as a means of diagnosing I/O errors rather than as a means of backing up and recovering data.
