Configuring failover monitoring and processing

Make sure you have a valid source and target specified, click Configure protection from the main Full-Server Failover Manager page, and then select the Failover tab.
Specify how you want to handle failover monitoring and processing.

Manual intervention required—By default, you will be notified when a failover is necessary, but the failover process will not start until you manually initiate it. If you disable intervention, failover will automatically start when a failure is detected.
Monitor Interval—By default, the target checks to see if the source is online every five (5) seconds. The source responds back to the target when it receives one of these checks. If desired, increase or decrease the interval between checks.
Missed intervals—By default, the target can miss five (5) responses from the source before assuming the source has failed. If desired, increase or decrease the number of responses that can be missed before the source is identified as failed.

Note:

Together, the Monitor interval and Missed intervals settings determine the total time before failover would be triggered. For example, five missed checks every five seconds would be 25 seconds to trigger failover. To achieve shorter delays before failover, use lower values. To achieve longer delays before failover, choose higher values.

Pre-Failover Script and Post-Failover Script—If you want to execute a script on the target before failover (pre-failover) begins or after failover has occurred (post-failover), specify the path to the script on the target. You can also search for the script by clicking Browse. The script will be processed using the same user account that is configured to run the Double-Take service. Scripts may contain any valid Windows command, executable, batch, or script file. The Pre-Failover Script will be executed as soon as the failover process is initiated. The Post-Failover Script will be executed after the failover process ends and the target has been rebooted.

Click OK to save the settings.
