Hey everyone. Just grabbed myself a nifty 2TB WD external to use with my rMBP. I'll be using it to run Time Machine backups as well as store my Movies/Music. I'll be excluding my Movies/Music from the TM backups so I can access them with out going in to Time Machine, but it'd be great if my external could 'peek' in to my system, see what's been added to the Movies folder, and copy those items over. Any software that might help with this?
