Roy,
what additional level of protection do you achieve sending *primary* (!!!)
pool tapes off-site?
Juraj is absolutely correct - this is very bad practice. Copy pool tapes
can be ejected from library right after their creation or even made on a
"manual" library consisting of standalone drive(s). Tape sent off-site can
easily become damaged when courier drops it moving it back and forth.
Whenever this happens you do not have the chance to do something
reasonable.
I hope with this installation you are not forced to meet any SLA
requirements.

Roy,
I hesitate to answer your question,
because it would support you in a VERY BAD practise.
I find operation with only single copy of data simply irresponsible.
The costs for second copy are very low - only couple of tape media.
Do rethink this design, consider creating backup pool.
This makes it possible to keep tapes from primary pool
unloaded from library but still on-site,
thus eliminating your find-correct-tape problem.

Juraj Salak
