JBoss EAP 6.3 - Domain Mode - Disaster Recovery

Hi guys,

I have a question about disaster recovery of DomainManager.
This is my scenario:
one server Master - DomainManager where I expose the WebConsole and CLI
two servers Slave - Connected to Master. Every server has a few of Configuration names in a few of Server Group

Our servers are located into two different geographic server farms because if a server farm go down the second one provides the service, but the problem is this: we have only one server Master.

I read the documentation about the "Command line parameters" and I saw that it is possible to execute the service with the switch "--backup" to take a local copy of the configuration but in my configuration I execute the service with a windows service and I can't use the "--backup" switch.

The questions are:
Is it possible to backup the entire directory D:\RedHat\jboss-eap-6.3 and restore to another server located in the remote farm ?
Is there a special method to start the web service from the slave server and get the domain.xml configuration in local ?
Is there a "guru" method that someone suggest to me to resolve that problem ?

Thanks in advice for every suggestions,
Roberto
