I have my main iTunes library housed on an external hard drive (called 'iTunes') that is connected to my Airport Extreme router. I want to be able to back it up onto an external hard drive ('iTunes backup') that I plug into my MBP periodically. I set up a scheduled task to automatically do this when the drives are both visible on the system, but when I plug in my 'iTunes backup' external drive to my MPB, the task does not begin. The only way to make it backup is to manually start it. I know this is a little counterintuitive to backup a network drive to a local drive, but is this something CCC or Mac OSX cannot do? Is there a setting I need to tweak to make the automatic backup occur when the backup drive is connected locally? Thanks!
