Sure we do it all the time.  It goes
Disk->OffsiteDLT
Disk->OnsiteDLT
Now just to catch anything that has skipped or migrated from disk do
OnsiteDLT->OffsiteDLT

Just make sure you use the same copytapepool for all the commands.

This is how we do ours every day.

You can also do it by turning on caching of the disk pools.  Since we
compress at the client, this can sometimes make a file fail if the disk pool
is getting full.  For this reason we do not use disk pool caching.

Hope that helps
