Data and features might be lost at the time of the failure. For instance:

Active monitoring and recording is stopped. They can be restarted manually

CAD uses LDAP replication to provide fault tolerance for configuration information,
such as work flows, agent hot seat settings, and so on. It uses MSDE merge

such as call logs, agent state logs, recording logs, and so on.
