A Failover Server service, which handles the processes of taking over from the recording server. This service is always running, and constantly checks the state of relevant recording servers

A Failover Recording Server service, which enables the failover recording server to act as a recording server.

In a cold standby setup, this service is only started when required, that is when the cold standby failover recording server takes over from the recording server. Starting this service typically takes a couple of seconds, but may take longer depending on local security settings and more.

In a hot standby setup, this service is always running, allowing the hot standby server to take over faster than the cold standby failover recording server.
