I was wondering if anyone had any experience of various online backup systems.

I currently backup the bulk of my stuff to an external HD, and use Dropbox for the more 'mission critical' stuff. However, if things ended up going all IndieStone on me I'd still end up losing several GB of stuff I'd quite like to keep.

Case in point, my users directory is 70GB, and while some of that will invariably be uneeded, it includes huge numbers of photos etc. I should also probably include my music in that, as if fire takes my computer, it'll also take the CD collection from which I could restore it.

Dropbox isn't really geared up for backing up everything I want, unless I'm prepared to pothole my entire system with symlnks.

So, I'm really looking for personal experience. Especially if you've had to use the restore feature.
