Hi Bob, I guess you are talking about the backup option?
Check out http://haproxy.1wt.eu/download/1.4/doc/configuration.txt in section 5: backup When "backup" is present on a server line, the server is only used in load balancing when all other non-backup servers are unavailable. Requests coming with a persistence cookie referencing the server will always be served though. By default, only the first operational backup server is used, unless the "allbackups" option is set in the backend. See also the "allbackups" option. So you basically configure two server in your listen/backend section. The backup server will have to contain the "backup" keyword.
