I am not sure whether it works with Mac, but I have been using CloneGenius (beta version) for a couple of years now.
It backs up the entire OS partition.
It is much faster than trying to reinstall everything. A 30gb partition takes about 40 minutes to back up (non-compressed). Reinstall, if necessary, also takes about 40 minutes.
CG operates from the CD drive, with its own OS. It reads USB external drives, so it is easy to direct the backed up files to write to USB drives.
USB drives are dirt cheap. I picked up one 320gb Western Digital this week at Walmart for $79.xx
Sounds good! There are so many tools at our disposal these days when it comes to backups, and just all around working on computers. We are certainly MUCH better off than we were just 5 or 6 years ago. Lately, I’ve been playing around allot with Virtualization. This is a very good time to be a geek. :p
The same with DVD backups. I have been tempted to go to an online backup. Still thinking about it.
