What customer environments best fit the BRMS Cloud solution as a full system recovery solution?
The BRMS cloud solution requires physical ISO format media to do a full system recovery. To produce the correct format, the virtual optical images that are generated have to use an image size of *DVD4700. If the size of the contents of any of the sequences in the QCLDBIPLxx default control group exceeds 47Gb (ten 4.7Gb volumes), BRMS does not recommend using the BRMS Cloud as a full system recovery solution.
What customer environments are best suitable for BRMS Cloud?
...
When using the BRMS supplied cloud control groups named QCLDIPLxx the backup always goes to virtual optical and the transfers are not initiated until after the control group is finished. This is because BRMS uses leave processing during the backup and appends to the optical volume set. Optical does not have an exit program available to call to initiate a transfer when a volume is full. By default, the QCLDIPLxx control group attributes for option 9 'Subsystems to process' value is set to Restart *YES which or when using restricted state batch processing, the subsystems will start the subsystems and allow automatic transfers to happen after the control group completes. If the Restart value is changed to *NO, BRMS does not do any special processing to start any subsystems and the automatic transfer request will fail. The volumes will stay in *TRF state until the problem is resolved. When the subsystem is started again, running STRMNTBRM will find and transfer any volumes left in *TRF state.
