I use mozy for my home backup and their system is good - their software works well on Mac and PC. They give you 2GB free which I haven't quite reached yet, but I might consider paying for unlimited when I do.

They hide their free 2GB offer now (at least, I couldn't find it) but you can access it at http://mozy.com/free

8. Dell and MessageOne ?

I have to assume that EMC is planning on building out these DC's with something other than Symmetrix and Clariion.

I did pay for the unlimited service. So far, they've got around 90GB of my data, and it's working nicely. I've done a few test restores, and they worked.

The Mac client is finally out of beta (though the beta worked for me without any issues).
