Re: Undelete files / directory

[Jean-Denis Girard <jd.girard@sysnux.pf>]

So I commented out the break on line 238 of btrfs-find-root so that it
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!


Best regards,
Jean-Denis Girard
