My feelings about Mozy are mixed. The first couple times I tried to use it on my work computers it never backed up anything, which was a problem, of course. I'm not sure if that was user error or an compatability with my computer or OS. A year later I was looking for a good online backup service to backup my home photos and videos. I tried Mozy again at home, and although it took forever to backup the initial content (20 GB), it works like a charm now. About $5 a month and keeps our photos and video safe--on the fly.
