Using the multitool to backup the whole system and restore it in new box

Hi Jock (Paolo)

I had sent a private message, but later I saw many messages from Charles Bauer, heading  a project where I am also involved.

Here, we are receiving some hundreds of TV BOX, MXQ PRO, model 3228A (probably 1 of RAM and 8 of ROM) and with the task to transform it
a Linux machine. Well, this task requires some scalability to do this conversion following a methodology. What I had thought:

1. Install  the ARMBIAN  in one these box, and configure it with all desired customizations

2. Do a back-up of this box using the Multitool (option for backup)
    I saw that the Multitool did a copy of whole eMMC (or NAND) memory... resulting in a file without extension of 7,8G (around this )
    My supposition  about this backup option, it generates  a whole image of this TV BOX,  and ready to be replicated in another similar box???
    Am I right?
3. Using the restore option, I choose this file to burn news TV BOX.  Am I correct in my reasoning?

Is there another stractegy to replicate a configuration in hundred of box?

Unfortunately, I can not do a dd from another Linux machine, using a male-to-male USB, once the MXQ PRO, with any powering in usb it boots!!!!

Any tips to replicate a hundred of  TVBOX in customized ARMBIAN? Am I correct to install the backup, an image, by restore with Multittol?
How can I copy with dd all the system from a TVBOX with Rockchip 322X ... it simply boots connecting any male-to-male  USB cable

Cheers in advance
