I'm interested in buying an external HD to back-up my MBP using Time Machine, but I have some questions left. I have the MBP's contenst (which I want backed up) and also another external 1TB (iomega ultramax) which contains all my movies/tv shows etc ... I want this Iomega HD backed up as well. So what happens if my Iomega drive crashes? Can I just purchase a new HD and put the contents back on there from the Time Machine back-up? Is it that simple?
