I back up all my important data to the cloud (to Amazon Glacier, if you're curious). The backup software I use encrypts my data using strong encryption - stuff the NSA can't break.
Backing up to the cloud is smart because you can lose your devices to theft or fire. It's inexpensive, and it's secure.
Oh don't worry. I'm sure NSA already has a backdoor to that encryption you're using.
Just trying to remove that damn setup progress bar.
