Hello.

I have been using rsync for a couple of months to provide synchronised
data between two of our servers and have had wonderful success with it.

I was wondering if anyone knew of another tool that might provide the
following:

        - "Real-time" push synchronization
        - rsync like "whats changed" algorithm
        - Distributed / Multiple-source synchronization
                eg: ServerA pushes to ServerB, then ServerC can receive
from ServerA and ServerB

Novell has a product called iFolder 3, but this requires a SUSE Linux
Enterprise Server with Novell's OES. But this is still Server->Node
synchronisation and not Server->Server

Did you check Unison? It uses rsync alghoritm, and if you want to create a multi-way syncing, you'd have to create a "star" topology (with a central server in the middle).

If you're familiar with rsync, you should be able to set up a multi way synchronization with Unison in an hour or two (though the flags are different); I can send you some of my scripts if you want.


If you want to achieve a real time synchronization, you'd have to play with a distributed filesystem like Coda, which would take you a couple of days to set up.
