I don't know the answer, but would surmise that at least 50% larger than what you're backing up. However, if you're almost full now, you best get another HD for that machine (if it can hold more than one) or an external, bootable FireWire HD and start backing up what you have now and freeing some space or you're going to experience difficulties. FWHDs up to 300 GB are available for under $200. Since Leopard isn't coming until next spring, you're living on the edge right now.
