What does Hot Standby mean, and what do I need to implement it?

Hot Standby is a method where ARC is configured for failover between two server nodes, one of which is active as the production server while the other is idle, or in standby mode, waiting for failover to occur. This allows for a shorter maintenance downtime and for quicker recovery in the event of a server outage.

You need ARC 6.0.2 or newer, and an external SQL database (postgreSQL or MSSQL) and two or more servers for ARC failover.
