Hi, I know that wireless backup can be done through a Time Capsule, but they're pretty expensive. Currently I have a wired 1TB backup drive that I have to plug into my MacBook each day to backup with Time Machine. Is there a way that I can hook up my external HDD to my network to allow me to then carry out this backup wirelessly? Further to this, once the drive is on my network, I assume locally it would be possible to store say my iTunes library on there and access it. Can this be done not locally too? Many thanks.
