I am using Mozy Remote Backup, in my long trail of testing backup solutions, this one is working well. Disclaimer: haven’t tried a restore yet.
I use it only for my “business” folder, not my images or music folders.
Every day, it automatically backs up my business folder when I’m away from my computer, and then, and this is the most satisfying bit, when I get back to my computer there’s a “your stuff is backed up!” notice. Aaaahhh. The feeling of satisfaction is very enjoyable!
