Time Machine Backup after HD replacement

[Matt-Man-Plus]

Hello, I just replaced the stock 160GB HD in my unibody macbook with a WD Blue Scorpio 640GB HD. I used Super Duper to clone the old drive to the new one, approximately 115 GB.

Now Time Machine wants to backup the full 115GB to my Time Capsule, which kinda sucks because it's going to be a redundent backup that's gonna take up over a 10th of my TC's space. Is there any way to avoid this and still use Time Machine?

When I upgraded my internal hard drive I could not find a way around not backing up the whole disk again. I decided to delete the old backup and leave the new backup to do its thing over night. (Somebody could prove me wrong)
