eheh thanks, also I tried asking Chat GPT what he thinks about my situation, my needings about my workflow and what are my requisites on a Linux distro. He said exactly Ubuntu and Derivates are a bit tight for my usecase. He suggest me using Fedora or OpenSuse or Arch .., or vanilla Debian Sid. I ended up trying Fedora. That’s all and I did not regret my choice.
Snapshots for quick roll-backs: A lightweight tool like Timeshift can take automatic Btrfs snapshots without replacing your full-disk
ddimage. It gives you a safety net for tweaks or updates while respecting the effort you already put into your backup routine.
Thanks Hydn for the tip, but the problem about using those tools are that I need to have an Unix file system (XFS, EXT4, BRTFS etc etc..) for keeping the backups. I have just one 4tb external disk and I prefer don’t split it’s partitions, just one big NTFS partition is great for my usecase.
In this case I can mount without problem the NTFS disk through Gparted live terminal and launch the dd command for save the image on the external disk.
In the end I will backup one unique .img file of the size of nearly 220gb which is storing all information about disk, data, bootloader, freespace.. lol 
If one day it’ll become a space problem I can starting rotating the backups, deleting the older ones.
I think it worth better using dd, 30 mins for a complete backup is an acceptable amount of time.
