• Configuration command backup

  When the primary configuration device and the secondary configuration device are functional and the manual batch synchronous backup is started on the primary configuration device, the primary configuration device sends the configuration commands requiring dual-system hot backup to the secondary configuration device in batch. Then the secondary configuration device runs these configurations.

  When the secondary configuration device is not functional or fails, manual batch backup cannot be performed.

• Connection state backup

  When the master and backup are functional and manual batch synchronous backup is started on the master, the master sends connection state information requiring dual-system hot backup to the backup in batch. Then the backup upgrades state information.

  When the backup is not functional or fails, manual batch backup cannot be performed.
