So I have an external hard drive that I use that's hooked through the USB of my time machine. Now that my Itunes library is getting rather large I'd like to move the whole thing to my external to use. I know that you can wake the drive to be accessable for Itunes libraries, but does Time Machine also back up the drives that are hooked through it so that my Itunes library isn't only on my networked external? Or just the internal drive of your comp? Been looking for articles but to no luck. Thanks.
