About storage unit groups for MSDP

Storage unit groups avoid a single point of failure that can interrupt backup service.
The best storage savings occur when a backup policy stores its data in the same deduplication destination disk pool instead of across multiple disk pools.

Veritas recommends that you select the method for the Storage unit selection type.
