Internal
Whether this server is using shared store or not. Default is false.
backup-group-name
This is the unique name which identifies a live/backup pair that should replicate with each other. Example: "pair-A".
check-for-live-server
If a replicated live server should check the current cluster to see if there is already a live server with the same node id. Default is false.
TODO: ?
failover-on-shutdown
Whether this backup server (if it is a backup server) becomes the live server on a normal server shutdown. Default is false.
allow-failback
Whether this server will automatically shutdown if the original live server comes back up. Default is true.
max-saved-replicated-journal-size
The maximum number of backup journals to keep after failback occurs. Specifying this attribute is only necessary if allow-failback is true. Default value is 2, which means that after 2 failbacks the backup server must be restarted in order to be able to replicate journal from live server and become backup again.
