How about Mac software that does backups by looking for what has been modified and then replacing only what is needed to the existing backup files to make them current. I currently backup to a second Glyph drive just by copy and paste. I have to create a new backup folder each time and them I trash the outdated folder. It's cumbersome but it works for now. What I need is Mac software (if available) that has a cherry picker style of backing up files. Isn't there something called Retrospect or something like that for Mac?
