We are doing this (same disk primary pool backed to two different tape
copy pools):
parallel
backup stg criticaldp criticaltc maxpr=1 wait=yes
backup stg criticaldp backupcopy maxpr=1 wait=yes
It results in:
143 Backup Storage Pool Primary Pool CRITICALDP, Copy Pool
CRITICALTC,
Files Backed Up: 2059, Bytes Backed Up:
66,581,766,144, Unreadable Files: 0,
Unreadable
Bytes: 0. Current Physical File
(bytes):
5,568,978,944 Current output volume:
AU0217.

It looks like TSM is smart enough to read the file from disk once, and
write to tape twice.
Does anyone know if this is the case and if/where it is documented?
