Example Configurations
Single Copy on Nearline Disk and Dual Copy on Tape
This data policy persists a single copy of each job sent to the system on to nearline disk and
two copies of the job on to 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 two tape partitions.
