rdiff-backup may not be the best tool for what you describe.

rdiff-backup maintains a full current backup and series of diffs to get
to older versions.  This works great if you are maintaining the whole
rdiff-backup on disk.

Unfortunately, if you want to keep the 'full backup' on CD, then you
will need to burn a new CD everyday, because rdiff-backup does not treat
that as static object.

I believe there is an alternate backup solution that works much like
rdiff-backup, but it keeps the original full-backup and a series of
diffs to move forward in time.  I'm not sure of the projects name
(duplicity?), but it sounds like it would work better for you.
