No.

The simple solution is to use a new CD for each backup, wasting most
of it. CDs are cheap, so it's not that bad. If you don't want to
waste any space, you can burn multi-session CDs, adding a new session
for each backup. Consider the risk, though, that the burning screws
up, and all the earlier sessions are lost.
