# High availability

You can optionally install one or more additional Management Servers or Log Servers.

If the active Management Server is damaged, loses power, or becomes otherwise unusable, additional Management Servers allow system control without delays and loss of configuration information. A special Management Server license for multiple Management Servers is required.
Note: The Forcepoint NGFW Security Management Center Appliance (SMC Appliance) does not support high availability for the Management Server or the Log Server.

Log Servers can also be used as backups for each other to allow continued operation when a Log Server goes offline. When a Log Server becomes unavailable, engines can automatically start sending new logs and monitoring data to another pre-selected Log Server. Log Servers do not automatically synchronize their data, but you can set up automatic tasks in the system for backing up important records.
