how can I check that all photos have been backed up in time machine
I have used Time Machine for the first time to back up my Macbook Air. Macbook Air's iPhoto shows approx 5200 pictures on file.
How can I check that the external hard drive (Time Machine) has all 5200 saved correctly before deleting the photos from the Macbook Air ?
iPhoto '08, Mac OS X (10.7.3)
