I keep my entire iTunes and iPhoto Libraries on my TC. (so they are NOT on my MBP)
I was manually backing these up to an external drive, attached to the TC - in the meantime trying every backup solution I could find.
some would not see the TC, and the ones that did would backup the ENTIRE iPhoto Library every backup.
Than I found Chronosync:

Unlike some of the other backup solutions I came across, chronosync can look 'inside' of the iPhoto Library, and update only changed files.
I have been using it for a few months, and it has been flawless.
