Depends how much you have to back up. Dropbox and sugarsync are the two main players, both with desktop apps that look after everything automatically. Dropbox give you 2GB for free and sugarsync give you 5GB for free, after that you need to stump up cash.
Sugarsync are cheaper.
Box only has a Web interface for home users.
Another one worth checking is Ubuntu one. Has a desktop app and gives 5GB for free.
No reason you can't try them all asks pick your fave.
Also, sugarsync and Ubuntu one allow you to stream your music to your phone
