When I run a Time Machine backup, does it back up all the photos I have in iPhoto? I am asking this because I bought my Mac in Jan. 2011. I ran my first Time Machine Back up in Feb. and I ran a second one just now. However, when I 'enter' Time Machine, it shows that iPhoto is only about 213 MB, (Not GB) and I know I have at least 80-100 GB of photos in iPhoto. Is there a way that I can enter Time Machine, and see exactly what in iPhoto has, or has not been backed up? Thank you!
