Here's what I want to do: 1) Have a bootable CD that only runs the backup program (OSX not running) 2) Create an image copy of my hard drive 3) Be able to browse through the image file when I am working in OSX so that I can pick out individual files if needed This is how I use Acronis TruImage on my Windows systems. For whatever reason, I don't trust backups made while the operating system is running. Maybe this comes from my old days trying to backup servers with ArcServe and having to buy a special addon to help you backup open files. I think it's just cleaner if I run the backup from a "dos" environment. I think my Acronis TruImage disc boots PC-DOS and runs only the TruImage software. Are there any solutions to do this with Mac?
