First of all, thank you Jonathan for writing this script. I'm much happier with this arrangement of backup files!
It didn't work out of the box on my Mac because the some of the OS paths were constructed with hard-coded Windows backslashes, so I went in and changed them to be platform independent.
I hope this is helpful to someone. Since I hadn't seen any later versions of this script, I went ahead and advanced the version #.
