It's still all toast.
That level of backup would handle any kind of physical failure - a dead drive, the destruction of your house, the failure of Google... but still, this thing would kill it.
There's only so much you can expect from a person when it comes to keeping their personal documents and family photos.
I mean obviously, if you're running a company you need a real backup solution, but for family files or a one-man-show business? There is no reasonable precaution.
