Time Machine only backs up your computer, not your external drives. Once it has done the first backup, it works very quickly. You need an external drive for it, however, about the size of your internal drive and preferably not USB. USB is very slow and inefficient compared to Firewire as it does not stream the data but sends it in packets.
I think Apple may have an unusually good Firewire implementation, and rather poor USB; I've found on Windows and Linux that there's little difference (after spending money for what was supposed to be a faster external drive solution).
