Hello. In my itunes library I have 35000 songs which I back up on an external drive and time machine.
My question is that if I import another album or two, how do I back this up without having to backup the whole library again which takes 3-4 hrs with usb2 and 1.30hrs through thunderbolt.
Up to now nobody i spoke to can answer this question.
P.S. I know time machine backs it up automatically. My question relates to backing up on other external hard drives.
