For the people with minimal experience on backups, and how not to lose all their passwords.
My experience, -do not repeat-
I wanted to re do the installation of qubes on my laptop with raid1 (instead of just upgrading from 4.2, I don’t know if it was possible).
So I did back up of all the qubes on an external drive.
(vault vm has my main db with all my passwords for encrypted disks, -no back up of that though-)
I though though that the backup needs to be encrypted so I canceled the previous one and made a new with a passphrase I saved inside vaultvm.
Happy that I have the passphrase and the back up I followed the instructions to install 4.3 on raid1.
Cool, now the back up.
Encrypted with a passphrase I don’t know and only remember partial words from the eff_large_wordlist of keepassxc. In which I added also some number because I though it would be better.
FUN.
EDIT: I am able to be logged in here from another laptop that I thought to log in before starting the re-installation in case that I needed advice on something. I didn’t think at that moment to save the passphrase 
EDIT2: If you know any ways that can mentally help me remember more of the words of the passphrase I am all ears. If someone wants to assist on breaking my passphrase (as that seems to only be the way to get my data back I will be following with a git repo with the scripts I will try) For compensation I can offer free beer if you make it to FOSDEM2026 
Lessons learned the hard way.
