For disaster recovery where high availability is required, you can use a hot standby strategy to ensure server availability in case of system failure. In this strategy, you maintain two servers and backup the file store and database as part of your regularly-scheduled system backup procedures. This enables you to immediately switch to the hot standby system should the primary system fail. A hot standby system configuration is shown in the following figure.
