Refer to the exhibit.
An organization has the requirements listed below for a server’s backup data.
Two copies must be retained for the same backup data.
One copy must be sent to disk with a retention period of one month.
A second copy must be sent to tape with a retention period of six months.
The copy on disk may only be automatically deleted by Symantec NetBackup after one month.
This must be configured without use of storage lifecycle policies.
How can a Symantec NetBackup 7.5 administrator configure a backup policy, maximizing automation, to meet these requirements?

A.
create a basic disk staging storage unit with a fixed retention of one month and staging to tape with a retention of six months; configure the backup policy to use
this disk

B.
configure the backup policy to back up to a basic disk with retention of one month; run the bpduplicate command to duplicate to tape with retention of six months

C.
configure two identical schedules for the same policy, then configure one schedule to go to a basic disk with retention of one month and configure the other
schedule to go to tape with retention of six months

D.
configure the backup policy so that the schedule creates multiple copies: one to basic disk with one month retention, and one to tape with six months retention
