Backup installation on emmc

I have installed CE on emmc. But not just CE, I have also installed docker, portainer etc
not from the service addons but from some alternate methods listed in some threads here. So I dont know where those have been installed.

I want to move all of that to another install. If i do a backup from CE settings addon these additions arent getting backed up. How can I make a full backup of the emmc to write to another machine? Something similar to cloning a boot micro SD

If you do a backup from ce it’s all gonna be there as its in kodi folder… Done that many times.
