Hello Picnaut,

It is very generous of you to offer to do this, but I can't help but feel that there is already a solution out there. I did some initial checking today and discovered a multitude of programs that offer selective file back-up, and some apparently with either version number and/or date archiving. Most also offered the ability to only back-up on change, which would be most desirable. Of course some of these packages are quite expensive, whereas others are very cheap if not free. I'll be checking this out in more details in the days to come, and post my results here.
