Backup with clonezilla failing

[Muffin]

I tried using clonezilla to create a backup of my steam deck, because I wanted to try installing windows on it to see if it'd fit me, but whenever I try to clone it to my new backup drive I get the error message: extfsclone.c: Couldn't find valid filesystem superblock.
I was wondering if there's a way to fix this without breaking the current installation of my steam deck

You may also use "dd". A quick dig on the net brought below nice article up.

Did you manage to fix this issue ?

I had the same problem, I solved it by using another USB disk (had this problem with every kingston drive I have) and Clonezilla live-20221110-lunar-amd64 instead of the latest one.

I've backed up 2.5tb of data (nvme + sd card) without any issue.

Not really no, valve themselves said they won't support it which is a shame

Try -fsck-src-part in clonezilla

I have since given my deck to my boyfriend since he lost his pc

Can't really check if it works now :c
