I have an external 500gb drive plugged into my brand new Time Capsule. The 500gb drive basically stores my entire library of music and my iTunes points to this external drive. Is it possible to have time machine backup all information on the 500gb drive to the time capsule, so encase the external drive takes a dump, I don't loose my entire music library? Maybe time machine is already doing this, I am not sure. Thanks for the help.
