FOXMAN-UN can be deployed with server redundancy. A main server provides the default FOXMAN-UN base and core services, and the database to which a client can connect. A warm standby or cold standby server is configured and is activated in case of non-availability of the main server.

With warm standby the services on the standby server are started automatically when switching over. With cold standby the services on the standby server need to be started manually.

A periodic database backup and replication ensures that main and standby servers have an up-to-date database.
