My tape drive crapped out :-< so....

I was wondering --- do any of you have a solution to backing up to
CD-Rs?  I have a fairly slowly-changing home directory at home (well,
except for digital photos, which I can back up separately), so I'd
like to have something that's able to do incremental backing up
(although CDs are getting so cheap).  CDs should be mostly OK for all
the text files, etc.

I tried burning tars onto multi-session CD-Rs with listed-incremental,
but am not sure how to avoid name collisions with the list files.

Thanks,
R
