iPhoto, iMovie, Final Cut Pro Backups
If i make changes to a photo in iPhoto, or changes to a clip in the time line in iMovie or Final Cut Pro, does time machine just make changes in the individual photo or clip in those packages or does it backup the whle package even though only a single change was made? If the whole package, do you have any suggestions on how to run sensible backups with these programs, so I don't run out of space on my backup hard drive. I have over 7,500 photos and over a hundred movies. I am constantly adding minor information changes to my photos and making minor edits to my movies.
