  35 # DESCRIPTION:
  36 #       ZFS can handle stream with multiple identical (same GUID) snapshots
  37 #
  38 # STRATEGY:
  39 #       1. Recursively backup snapshot
  40 #       2. Restore it to the given filesystem
  41 #       3. Resend the snapshot again
  42 #       4. Verify this stream can be restore to this filesystem again
