No, what I was mentioning here is what I have read as standard linux functionality with copying, when a file is copied, and it doesn't matter where to, rather than create a 2nd copy of the file, the "copy" is created as a hard link to the original file, for storage efficiency, and then when one of the files is updated the hardlink is broken and both files become physical.
Considering all the grinding noises my hard drive makes if I copy a file, I wouldn't have said it works in that way.
