Hi,
I tried to recover an accidentally deleted text file from a btrfs volume using
the trusty old ''grep --text -C 500'' method and failed, since
the filesystem was
compressed. So I wrote a shell script that uses btrfs-progs for a proper
undelete functionality.
Attached is the script that implements a working btrfs-undelete using the find-
root and restore tools from btrfs-progs. It is fairly complete and solid and
it even has some command line help. It needs bash and common unix utilities
(sed, grep, wc, dirname, sort). I have successfully used it to recover a
couple of files I deleted accidentally and was able to recover 2/3 of them just
fine. The rest was zero-sized, I assume that''s because the file blocks
have
already been reused.
If you like it, feel free to add it to btrfs-progs. I''ve chosen GPLv2
or later
as license, as that''s what btrfs-progs seems to use.
Please CC me on replies, I am not subscribed (and don''t intend to).
