This command reads [C] network information data that can be then restored to another [C] to make a clone of the original [C]. The backup data structure is not public and it is encrypted (except the very last byte) by an AES-128 algorithm using an access password as a key. Backup data does not contain the device configuration. Use Read TR Configuration and Write TR Configuration instead.

NetworkData One block of the [C] network info data
To read all data blocks just start with Index = 0 and execute the Backup request. Then store the received data block from the response. The last byte of the read data specifies how many data blocks remain to be read. So, if this byte is not 0 just increment Index (0, 1, …) and execute another Backup request.
