There has been siginificant discussion on incremental backups in Lightroom and the need for that ability. I have a solution easy to implement that should work well. If we could add a metadata tag that was the date and time last edited, via development of some kind, or additional of snapshots, etc., then we could filter on that metadata and produce an export to cd or hard drive.

This would enable daily, weekly, or other timespanned backups. It would also leave all the work in lightroom.

What do you think?? Other ideas??
