[keycloak-user] multiple ldap servers (failover)

Hi all, We've just found keycloak, and are evaluating it. It's looking great so far! We have two questions. Question one: We are running three AD DCs, and would like to configure all three in keycloak, to get failover & redundancy. To do this, I have simply configured three comma-seperated DCs in the ldap URL field. Keycloak accepted this input, but I'm not sure that all three will be used... Is the above the way to provide multiple ldap servers to keycloak? Question two: How about backing up keycloak? We are running from an extracted tar.gz. If we keep backups of this keycloak-directory, is that enough? Does keycloak need to be shutdown at backup time? Best regards, MJ
