You wouldnt be able to set up a copypool for the offsite copy it would
have to be another onsite pool. You could always try using the devcl
type of file and going that route.

I would also look at doing the dbbackups as devcl=file. That is what we
are looking at doing to reduce the waste of gigs of tape for a rather
small db.
