Backupify

My first Backupify email arrived today telling me that my precious cloud data had been successfully backed up; to the cloud.  I suppose this should make me feel more at ease with storing all of my life’s 1’s and zero’s in some ephemeral gaseous state.  What if the entire cloud dissipated?  It wouldn’t really matter where that my email was in two different parts of it, would it?  But I guess the chances of that happening are very small.  I mean my Internet is more likely to go down than to have anything happen to the cloud.  I wonder.  If the internet goes down, is the cloud still the cloud if I am no longer connected to it?
