I think this is what you are looking for (lists.freebsd.org seems to down at 
the moment, so I can't confirm this is the thread I think it is):
http://lists.freebsd.org/pipermail/freebsd-questions/2004-November/064560.html

Anyway, to backup /usr directly to a dvd(+rw), I use the this command:
dump -0 -uL -C16 -B4589840 -P 'growisofs -speed=4 -Z /dev/dvd=/dev/fd/0 ' /usr
This gives you a dvd or series of dvds with the dump file on them. You can 
then boot from CD2 (live system) and use restore to restore the data. If the 
link above is the one I think it is, it gives you an example restore command.

Hope that's the kind of thing you are after.

Cheers,
