I just purchased a LaCie d2 Extreme external HD for backup purposes and have a couple of questions: 1. My LaCie came with Silverkeeper software, but is it worth buying a copy of Superduper instead to create bootable back-ups? 2. I want to clone both of my computers automatically on a regular basis. Can I permanently connect my Powermac via Firewire 800 and my Mini via Firewire 400 to the LaCie (it is a triple interface model), then set the backup hardware to clone each machine regularly? 3. If both of my computers are cloned on the same external HD (in 2 separate partitions), what happens if I need to boot one machine from the external HD - will it know automatically what partition to boot from? Thanks!
