Here is the cheap route that I went. As long as you are not needing GIGs at a time and are only concerned with data. I formatted a CDRW to work like a floppy, I then made a BAT file to erase the CDRW, PKzip a certain directory and also recurse sub directories, then the bat file moves my zipped file to the CDRW. Works great for me. After compression the files I need backed up are only 500megs or so. So I have 2 weeks worth of CDRW's and everyday I put in the correct CDRW and go to work. I use WinXP scheduler to run the bat file at 11am and I am all backup up and ready to roll when I get home. If you are needing GIG's of space, you can use a second hard drive and use a bat file just the same.
