To configure the Cluster Edition for a dedicated method, use:
sp_addserver 'SYB_BACKUP', NULL, '$DEDICATED'
Each instance in a cluster configured for a dedicated Backup Server method must include a Backup Server.
When a user connects to instance “cookie” using isql and issues a dump or load command, instance cat finds the SYB_BACKUP entry in sysservers pointing to the '$DEDICATED' keyword. If the specified Backup Server (‘cookie_BS’) is not running, the Cluster Edition automatically restarts this Backup Server.
