The data backup in the WAC backup process is implemented through HSB (Hot Standby Backup). HSB supports multiple data synchronization methods. Among them, the scheduled synchronization method further ensures that the table items on the primary and backup devices are completely consistent. The backup device will check whether its existing session table items are consistent with the primary device every () minutes. If they are inconsistent, the session table items on the primary device will be synchronized to the backup device.
