I'm going to configure ISPConfigon 2 sercers. Oen will be MASTER (email, domains, mysql etc.) and second will be SLAVE (different then MASTER email, domains, mysql). I know the database can be replicated. My question is if mail, ftp and other configuration can also replicate from MASTER to SLAVE and also SLAVE to MASTER. If ie SLAVE is broken - does MASTER takes over ie. email tasks from master) also if MASTER fails does SLAVE can work with his configuration and replicated configuration from MASTER.
