Specifying how to manage groups of data sets

During backup processing, DFSMShsm processes individual SMS-managed data sets to comply with the attributes specified in the management classes to which the data sets are associated. Management class backup attributes let you specify:
  • Whether to use concurrent copy
  • How often the data sets can be backed up
  • How to guarantee frequency of backup
  • How many backup versions (maximum) to keep
  • How long to keep backup versions
  • Who can back up data sets by command
  • Whether to perform automatic backup
