Onan the Clumsy,
I can guess by your Tag, you do not want to spend any money, but you have to figure out how much your data is worth if it is destroyed (Fire, Virus, etc.) or hacked and broadcast all over the Internet.
First option for your notebook computer. My guess is that it has a network card built in. You could connect the computer to your Business network and transfer the files over your LAN to a computer that has a CD-Burner. Then you could get a hard copy of your data, (that does not require putting it out on the net).
There are three other options for you:
1) USB Hard Drive. It is fast and easy to backup anything you want:
2) USB CD-Burner or DVD Burner. It lets you make hard copies of your data from any computer:
3) USB Flash Drive. They are great since you plug them in any USB port and copy your data, then put it in your pocket. (Up to 2Gb of Solid State Storage):
Take Care,
Richard
