Control groups consist of groups of libraries, objects, folders, spooled files, and other types of data that share common characteristics or that you want grouped together for backup purposes. Whereas policies determine how data is processed, control groups determine, by their content, which data to process. They also specify what kind of backup you want BRMS to perform, such as full, incremental, or cumulative-incremental. In addition, control groups specify which days the data will be processed, and the order in which the processing occurs. Control groups usually refer to, and work with, related policies. You can set control group attributes to override policy decisions.
Though you cannot create control groups specifically for a recovery job, BRMS does efficiently recover data by control groups.
