Thanks for that report.
Can a developer review this and see if it should be made an option or
removed entirely?
I think that is the best way to proceed, or maybe even better make a
"brute force" option for btrfs restore that does something like my for
loop, recovering what it can through the filesystem.
Until then, can we make this into a concise set of instructions so we
can post it on the wiki?

continues even if it thinks it went past the fs size, rerun the command,
and I finally got a list of blocks to try!
Then as you suggested I did:
for i in `awk '{print $3}' root.txt`
do echo "------------------------ $i --------------------"
btrfs restore -v -f $i --path-regex '^/(|jdg(|/tmp(|/.*)))$' \
../x220_home.img .
done
And I now have back my ~2800 photos (~13 Gb).
Many thanks to those who helped!
I am glad i could help!
Best regards,

Hi all,
I did a successful btrfs restore a few months ago, saving all of my
deleted files except 2 (So i lost about 1GB on a 4TB filesystem)
Here is what i did (this is from memory and from my .zsh_history file,
so i may be missing something)
btrfs-find-root /dev/sdd -o 5 > b1.txt
I think the -o 5 option is quite important here.
Thanks for the reply, but for some reason btrfs-fins-root does not work
on this file system. Here is what I get:
[jdg@tiare tmp]$ btrfs-find-root x220_home.img -o 5
Super think's the tree root is at 115230801920, chunk root 131072
Went past the fs size, exiting[jdg@tiare tmp]$
I can mount the file system, access the files, though obviously not the
deleted directory.
Regards,
Jean-Denis Girard
