I am well above average when it comes to backing my files up on the computer. Of course there is always something you forget to backup. I have been burned more than once by loosing important information. Last month I started using rsycn a bit to backup my files. I am trying to get a bit more advanced in how I use the tool.
I also decided instead of backing up my data to a firewire drive attached to my Powerbook that I would backup the data to another firewire drive connected to my desktop. In order to do that I am moving files around on my desktop to allow me to use the firewire drive as a backup only drive.
ISO’s and virtual machines sure do take up allot of space.
