Hello, currently I am trying to recover a btrfs filesystem which had a few subvolumes. When running # btrfs restore -sx /dev/xxx . one subvolume gets restored.
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.
