By tape drive, the docs mean pretty much any device, including (in
this case) a flat file.
Check dump(8), particularly the -f parameter.
>From there, the dump file can be poured into a .iso image and burned
to a CD or DVD. Automagically, if you're diligent about keeping
blanks in your drive.
There were some scripts for automating some of this process floating
around once upon a time, I'd sure like to see something like this
again - particularly written in perl. If they don't show up in
response to this thread, maybe I'll hack some together myself.
I'm in the late stages of tweaking a new box out, and once I get
amavisd and clamav integrated with postfix, I'll probably be down to
the backup process myself.
Very timely thread from my POV :)

The perversity of nature is nowhere better demonstrated by the fact
that, when exposed to the same atmosphere, bread becomes hard while
crackers become soft.
