The backup menu allows you to run a second Master as backup device in the same domain as the “show” Master device without causing any conflict. As long as this device is in Backup Mode, it won’t give out any control data.
If it is necessary to change over to the backup device, this backup Master may take over all sites in the domain in order to run the show.
To change a Master into backup mode, go to the Backup menu and choose “Change Mode to Backup”. The status line at the bottom of the user interface displays “Backup” highlighted in orange instead of “Live”. When you have to change over to Show Mode, choose “Take Over All Sites In Domain” from the Backup Menu.
