Using Super Duper I've created a bootable backup drive for my PowerBook. The idea is to have Time Machine doing regular backups on the same drive, but also having it bootable in case of an emergency. However, Super Duper has copied the entire drive (that's the only choice in unregistered mode as far as I know), and when I try to start Time Machine it attempts to back up my entire drive again. I assume if configure Time Machine not to copy certain folders (e.g. System, Applications...) then it won't make any backups of them later on even if things inside of them change. And if I leave Time Machine as it is and instead remove files the backup drive so far (the files/folders Super Duper copied) then I won't have a bootable drive any longer, so what do I do? I'm running MacOSX 10.5 (10.5.8?) on a PowerBook G4.
