Copy and continue with original file

Hi,
I'm sure I'm not the first to ask, but these seem to be impossible keywords to find relevant posts with
What is the best way to make a copy of a file and then continue to work with the original? Hazel's behaviour is to my mind a bit counterintuitive in that it will 'follow' the copy and continue to work with that.
My scenario is to back up a file externally before doing anything further to it. One way is to make a copy and then copy it back. Unnecessary round trip, not ideal.
My current solution is to move the file to an intermediate folder and then do the backup copy. A second Hazel rule then monitors the intermediate folder and runs the next actions from there. Works, but just seems rather awkward.
Using this technique I have 9 folders to perform actions on my incoming files, where only 4 are really needed. So I was wondering if there is a more effective way to do this? Or anything I've missed?
Any info appreciated, thanks.
