Windows 7

I currently use a WD Passport hard drive to keep my data on. It is small enough to throw in my laptop bag. Once a week, I copy everything on that drive to another USB hard drive, a 500 gig 3.5" WD Caviar IDE drive in a USB enclosure. I rotate among three of those drive/drive enclosures and keep one off site about 40 miles away from here that I rotate out once a week and another in a safety deposit box at my bank. I've had my own practice for 7+ years now and I definitely do not want to lose all that work to a stupid computer disaster, an issue with mother nature, or some thief that actually gets through my door, my dog, and my gun.

Edited to add:

I'm probably going to upgrade around Christmas time and go with a 2.5" Sata WD drive and eSata/USB hard drive enclosure and I am going to upgrade all the backup drives to 3.5" Satas in eSata enclosures. Backing stuff up is just taking way too long nowadays.

I also do a mirror backup of my operating system hard drive to another local hard drive inside the machine. Not the best backup, but the programs themselves can always be replaced, the data cannot.
