My context was that, independent of any actual backup solution, in Vista and 7 shadow copy gave you file history across pretty much the whole drive (this was separate from "System Restore"). This made it trivial to deal with restoring some previous version of a file or folder even days later. If you ever had that problem, shadow copy would have solved it*

* I think it was not in Home Edition, so yes, thumbs down on that
