What if your computer dies? Is there an easy way to get the data back? What if your computer dies and you've moved to another country? (These are honest questions - I'm not asking rhetorically.)
The main feature of skydrive is dropbox-ish cloud storage that syncs a folder on your computer with their online storage. To "recover" you can just log in to a web browser and download the files.
I guess the "expected solution" would be that you can install the desktop client on a new computer, log in to your account and start syncing from anywhere in the world.
