Thema: Full Backup! For recovery.

Hi
I would like to make a backup that would be completely full for recorvery.
What do I want to achieve?
I would like to have a complete backup of the entire image of the receiver on the USB Stick including settings, picons, bouquet, all already installed plugins, cccam and others.
So, in the event of a failure, all you have to do is flash this image without any additional settings or installations, with properly arranged bouquet, picons ect.
So that after flashing this image, and reboot the receiver was in the same stage as at the time of backup.
Is it possible?
If it is, can anyone tell me how to do it?
Is it from the level of the receiver itself or e.g. via a network on a PC?

I would like to test different configurations, different images.
Such a USB stick for recovery would greatly simplify me and speed up the return to what I have now.

Thanks.

Yes, I already make backup, but I need be 100% it will works like recovery with all settings, plugins ect. It is quite important for me, before I will make any change in receiver.
