What I'd now like to do is to backup both Macs (a Mac mini that stays on my desk at home and a MacBook Air that travels everywhere with me, in case you haven't read the links above) to a mirrored NAS via Time Machine, and then have the mirrored NAS backup to the cloud. I'm aware of the potential compatability problems between Time Machine and certain NAS drives, but as for the rest, well:
Has anyone got this to work? Is there a specific cloud service that you could recommend? And what do the Time Machine files actually look like: would I be screwed if my office caught fire while the NAS was in the middle of sending data to the cloud?
