looks like command was executed successfully when I added sudo, no errors. but still the same errors in backup. It's weird it says "image saved successfully", but giving those errors on checking the saved image. Something is wrong.

yes, I did, and never saw any error after entering passphrase, so my understanding was passphrase is correct. Does it show any error to the user immediately or only in the end of the backup?

Running: cryptsetup open --type luks /dev/nvme0n1p3 luks-27dc5174-93c1-4737-9f6e-74a7f9376da1" -> When this command is run, did you see any error messages? I did not see that in the log file "clonezilla-img" should I type this command before or after backup?

also tried to save disk in dd mode but received similar errors, though I was expecting no errors at all. It is DD mode, why the partclone is triggered at all? this makes no sense

I tried to restore image to USB stick, but got the same error during restoration. I think I saw more erros, something "LUKS cannot create a password or partition", but i dont see them in the log. Log seems to be grabbing not all errors

Please do more tests there and let us know if all the data and functions work well in the cloned OS. but the backup is broken, it failed. If I restore cloned OS from a broken backup, I will lose both source installation and backup. I will have no working instance of Qubes if my backup doesn't work.

yes, QubesOS runs and boots perfectly fine. Have you ever tested Clonezilla against Qubes?
