You don't need two separate SDs to do that. The Copy job will copy a job
stored on a tape belonging to one pool to a tape belonging to another
(different) pool. Say there are two pools, P1 and P2. All tapes loaded
into library 1 are put into pool P1. All tapes in library 2 are put into
pool P2. A backup job is defined with Pool=P1 and NextPool=P2. So the
backup job always writes to tapes in pool P1, and every tape in P1 is in
library 1. When a copy job is later run, it will use the NextPool
defined for the pool the backup job was written to, which is in this
case P2. So, the copy job will copy the original backup job from a tape
in pool P1, writing it to a tape in pool P2. Because all of the P2 tapes
are in library 2 and all of the P1 tapes are in library 1, the copy job
will always copy from a library 1 tape to a library 2 tape.
