No, you misunderstand it.
This plugin is device-specific and firmware-specific. Unfortunately, devices differ in the way they use memory. Even memory capacity can affect the proper functioning of BackupSuite (you need a USB stick if you have little space in Internet flash memory or RAM and you may need EXT filesystem instead of FAT). They are also different in CFE-bootloaders, so loading the image into memory is different. Therefore, BackSuite on some devices must assume a different type of CFE-bootloader.
Unfortunately, BackupSuite is not universal, although many developers have customized this plugin to work with each one firmware. Then, for example, a different type of the Shell or a different version of the BusyBox in Linux is enough to make a problem.
I think it's stupid to make a full backup image. In my opinion, it is better to download the firmware from the internet, flash it, then add the necessary plugins and files, and finally replace the backed up file "/etc/enigma2/settings" or rather the entire contents of the "/etc/enigma2" folder. With Enigma2 stopped with "init 4" command in the Shell, of course.
If you want to solve functionality, you have to put the exact details of the problem and best on github (if you use OpenVisionE2 or OpenPLi, write about the problem on their Github server to Issues).
