Important Aside: The one time I had to resort to btrfs restore I didn't
get the contents of _many_ of the really small files. My _guess_ is that
those where the files small enough to reside entirely within the
original filesystem's metadata.
You should mount the filesystem read-only and recursively copy the
hirearchy to another file system as well as doing a restore. The two
results can then be folded together, or at least the former might help
you find some of what the latter might miss.
I could be totally wrong, or restore could have been improved since
then, but it was what seemed to be happening.
