I would like to get some opinions on this. I have an airport extreme with an external drive hooked up to it for backing up my hard drive on my macbook. I have 2 options..... 1. Time Machine .... good for lost files, but not quite as easy to restore from. or 3. SuperDuper! ..... makes an exact duplicate of my drive using "smart update". I can schedule it to back up my drive every night and it takes very little time after the initial backup is made. Can't go back in time and grab a file, but I can just copy the backup to a firewire and boot from it and I'm right back where I started from. Which is the better way to go?
