VIM2 1.4 how to clone it?

[RDFTKV]

Hello, User balbes150 offers some Linux varieties that boot/run from SD card or USB attached storage. Those have a script called DDBR, a backup/restore script that can backup the entire eMMC and restore it. I would think that could be used for multiple identical devices. I have not tried doing so myself, so not sure.
I am on an old phone now, when I get to a PC, I will post links. It will be a couple of hours before I get there.
Other options may exist, I have not tried cloning these devices, so cannot offer experience.
Update:
Info about using DDBR is here.

Note.
These systems are based on Armbian. For more information on setting up and working in Armbian see the relevant threads on this forum or on the forum Armbian.

You can proceed to the second stage, the creation of the full backup.

Start creating a full backup of the entire contents of eMMC.

For the console version to run the utility “ddbr” and follow the prompts (select mode to create a compressed copy).

For the full (graphical) system, you need to run the terminal to switch to user “root”. For this you need to run the command “su -” (su space minus). And run backup “ddbr”, then follow its tips to create the compressed copy.
