[SAGE] OS X backup to CD-R?

[Pat Wilson <paw@noh.ucsd.edu>]

I've got this very nice new iceBook running Mac OS X.  It would seem the obvious
thing to back it up to the built-in CD/R (I'm thinking "multi-tape", and
burning when it's time to change media).  I can't, however, get /sbin/dump
to talk to the CD/R device.

Has anyone gotten this to work?  Failing that, how _are_ you backing up?
I've found something called hfspax, but am not really sure it'll do (and
it's a <shudder> binary)...

Thanks.
