First I hope I'm not spamming this topic too much, but Dropbox' (I actually prefer copy.com) enormous advantage is it hasn't got a file (amount) limit, which means it can easily be used to backup without archiving things first (WordPress 3.8 currently contains 1162 files). Not even talking about using services like Git.

Also it comes with still some slightly odd way of revisioning control.

Dropbox and Cloudup have different things in mind when it comes to storage, but still, above can be viewed as an advantage.
