Is it possible to use "Time-Machine" with an external hard-drive through an IP?

I have an external HD connected to a Raspberry Pi and I have installed SSH. What I am hoping to achieve is this:

I have a Mac Mini and a Macbook Pro, I want their back-ups to be in-sync but, through the user of an IP that is directed to the raspberry pi that connects the hard-drive. I know/read that this is possible using Airport extreme but, I do not have that, instead a standard router but I am able to port forward.

Can anyone recommend any open source solutions rather than needing a Time Capsule or OS X Server running on the NAS?

What do you mean by "backups being in sync"? Are you looking for a backup or for a syncing solution? Mixing these two concepts may lead to very bad results... – patrix Jan 12 '13 at 10:58
@patrix Thanks for the reply. So I could use a back-up for my mac mini but it also backs-up the file on my MBP as well. M main concern is setting time-machine using an IP.. Any ideas? :) – Phorce Jan 12 '13 at 11:02
You need a way to make the drive visible to the Mac (like a conventional NAS). Don't think SSH will help here, you need to run something like NFS on the Pi (and then make sure that OS X accepts the shared drive as a backup destination). – patrix Jan 12 '13 at 11:07
@patrix network based time machine requires server side software, plain NAS will most likely not work well. – Thorbjørn Ravn Andersen Jan 13 '13 at 11:44
@ThorbjørnRavnAndersen Thank's for your reply. Could you suggest any tutorials online? – Phorce Jan 13 '13 at 11:55

I think what you really want is Netatalk. It is excellent software, and if run with a zfs backend, it is simply perfect as a time machine target.
