Sorry, I forgot this. Hier is the output:

The new image is same size, and since it seems small to me I am
attaching it to this mail.
What do you get for `btrfs insp dump-t -d /dev/` ?
Once I restore it, I get
$ sudo btrfs insp dump-t -d /dev/mapper/vg-nik
btrfs-progs v4.20.2

There is a valid superblock however. So it restored something, just
not everything, not sure. Might be related to create failed success!
Do anybody need something else from this filesystem? If not - I would be
glad to reformat and reuse this ssd partition.
Kind regards,
Nik.
