Btrfs devel - May 2012 - Could btrfs-restore be extended to also restore file dates?

Any possibility of getting btrfs-restore to also restore the files
timestamp?

I''m doing a restore right now as I had one btrfs partition blow up and
I''m noting that the timestamps are marking all the restored files as
new. It would be nice to be able to do a quick compare of file dates to
determine any changed files that may be newer on the restore vs the
backup. (I can save full file compares for when the server is not being
actively used.)

I do realize it is possible that there could be other issues, but for
quickly determining potential issues this could be useful.

I do realize that there may be technical reasons for the current
behavior, so at the very least this is suggestion for future
functionality even if it doesn''t help me.

Quick look, yes it is possible and quite straightforward. The function
restore.c:copy_file has direct access to the found on-disk inode item
and can access the time fileds, then simply setting them for the file.
Maybe it could restore more, like uid, gid or mode.

I''m sure restoring all those fields would be functionality that most
server admins would want. If anyone on this list can add it, then you
have my thanks.
