The esaiest solution to synchronize two servers with ISPConfig 2 is to synchronize the bind config files with rsync.

ISPConfig 3 will support multi server setups where you may have multiple dns, mail, web and database servers incl. replication from one interface, but ISPConfig 2 is build to be used on single servers, thats why it is not so easy to replicate the data.
Ok, how about this method: I'm thinking we could use ge as the live machine; users would use ge for mail, admins would log in to ge, etc. Ga would then be a hot backup machine. An rsync script could keep the named zone record files current, with reloads performed when changes are actually detected/transferred. Our Cisco GSS could most likely be configured to take care of the actual failover.

And as a related issue, when ISPConfig 3 is available, do you expect it will be possible to upgrade from version 2, as opposed to a clean install with mysqldumps, etc?
