title: How to take a recursive snapshot of a btrfs subvol?
body: <p>Assume that a btrfs subvol named "child-subvol" is within a another subvol say, "root-subvol" and if we take snapshot of "root-subvol" then, the "child-subvol" should also be taken a snapshot.</p>
  
  <p>Since recursive snapshot support is not yet there in btrfs file system, how can this be achieved alternatively ?</p>
