I've been Googling this and fiddling with my computers and not finding anything helpful or current. I'm using a G5 to serve my iTunes content and provide backup to all my computers with internal disks. It is loaded with Leopard. All my macs are on Lion. Everything is connected through gigabyte ethernet using an airport extreme. How do I get my Lion machines to see the shared disk on my G5 using Time Machine? Even with the shared disk mounted, Time Machine does not see it. I may move to Chronosync at some point, seeing the great reviews, but for now I just want to use a simple and free solution to get going.
