All of the attributes on the Change Backup Control Group Attributes display default to values that BRMS establishes in the backup policy (*BKUPCY) except one. You can override any of the shared default values by changing the shared parameters on this display.
The Parallel device resources parameter on the Change Backup Control Group Attributes display is the only parameter that is not shared by the backup policy. Parallel device resource capability allows you to save data to multiple devices from the same job at the same time, thereby shortening your save window. To use the parallel device resource feature you need to have multiple tape devices attached to your system. You can find more detailed information about parallel processing in the Additional Options for Processing Control Groups section of this chapter.
