Role of RDS "Session host" and "Connection Broker"?

Question

System administration

The question arose: There are two Session hosts and one Connection Broker, we know one hundred and all user data is stored on "Session host"s and the user uses resources, What will happen if one "Session host" server falls, then the user who has always connected to this server will lose his data, or is there some kind of replication between servers?
Thanks

Configure the User Profile Disk section in the Remote Session Collection properties on the broker
