Single Copy on Nearline Disk and Tape
This data policy persists a single copy of each job sent to the system on to both nearline
disk and tape media. Once data is written on both disk and tape, it is removed from the
BlackPearl cache if the system detects that more cache space is needed for incoming data.
Note:
This data policy is automatically created when the system detects a disk partition
and a tape partition.
