Alright, here's a funny question. I'm a DJ, and I use iTunes locally on my MacBook Air for my music. I also have my backup hard drive, to which I have copied my iTunes library to as the master storage. This backup of the iTunes folder is separate from the Time Machine Backups on the same disk.
I'd like to have just a select number of songs available on my machine (with it's wonderful, adorable 256GB SSD and all) and the entirety of my library on the external drive. When I get new music, I want to be able to add it to the iTunes library on the master disk so that everything is up to date. The reason for this is so that my fellow DJ can access that hard-drive with her own MacBook Pro to pull from the pool of music, and add to it with her own purchases.
Now, I realize that iTunes allows me to download songs I have previously purchased to my machine. This means I can pull purchases my assistant has made onto my local machine (and vice versa), and then also save them onto the master storage.
My real question is this: is there a way to succinctly sync the iTunes folder Time-Machine-style outside of the typical Time Machine backup location? I suppose it would work a bit like GitHub: there would be a central "repo" which all of the master changes are synced, and my assistant and I can pull what we need from it and add new songs to it, keeping the master storage up to date with every song we own.
The cumbersome way to do this would be to manually drag all of the new purchases into the iTunes Media folder when we buy them. There must be an easier way to do this! We want one big master library that we can easily sync to and pull from. Any cool way to do this?
(P.S. I am a programmer, so any sort of geeky or programmatic way to do this is heartily invited!)
