Is this Mac based storage solution doable?

[bmckenney]

I will be using a headless Mac Mini music server. There is an older iMac in the house as well. I would like a dedicated external storage device for the Mac for the iTunes store using either a USB or Firewire interface. My DAC will be Firewire so I might use the USB interface for the external storage. I would also like another larger external storage device, either desktop or portable, for backing up the music store, and for backing up the older iMac as well.

 

I'm assuming I can use Mac Time Machine on the Mini to easily backup the the primary music store disk to the backup disk thru the Mini. And can I see the backup disk on the Mac Mini from the iMac so that I can backup the iMac to it?
