dd was the universally-recommended tool for this, specifically something
like:
dd if=/dev/rrzwhatever of=/dev/rmtwhatever bs=64k
Cautionary notes indicated that the database *must* be down for this to work
(which it was in our case), and since dd didn't have any smarts to deal with
multiple tape volumes, the tape must be larger than the device being backed
up.
As it turned out, the database people got comfortable with their backup
procedures and we didn't have to do this, but it made everyone feel better
that we _could_ do this if we needed to.
Thanks for all the responses.
