I am debating creating a bootable backup of Leopard. Right now, I've got 10.5.1 humming along nicely on my PowerBook, with an OWC portable drive partitioned for Time Machine plus general data storage. I am planning on sending back the OWC drive for a larger one, and when I get it I was thinking about creating a third partition, and using that as bootable backup for OS X. Since Time Machine isn't bootable without a Leopard DVD. I'm curious what's the best program for doing a barebones backup? I don't need all of my apps available to me, although if I was stuck with that, I suppose I could make the partition slightly larger. I just want bootable OS X. Can I do that with Super Duper or CCC and ignore the Apps folder or just certain apps? Will bad things happen? I just don't want a 20 GB partition to boot 6.5 GB worth of OS.
