I have an new drive coming that I'd like to put in an enclosure (and I have one already, but its sort of...used...right now). I want to put an 80GB partition on the new drive to serve as an exact backup of my PB drive. Figure I'll back up the entire drive every few days. Questions: 1. What's the best way to do this? Is there an app in Tiger that will facilitate this, or do I need 3rd party software? I think I'd prefer to do it manually rather than having it happen automatically, but I'd like it to be easy (open program, push button...). 2. Given that I'll be backing up 80GB at a time, can I assume that a FW800 enclosure will make a notable difference in how long it takes vs. a FW400 enclosure? Thanks!
