title: How do I send btrfs snapshots to multiple destination drives?
body: <p>How do I make a BTRFS <a href="https://btrfs.wiki.kernel.org/index.php/Incremental_Backup#Incremental_Operation" rel="nofollow noreferrer">incremental backup</a> to multiple source destinations, so I don't have to run <code>btrfs send</code> multiple times?</p>
  
  <pre><code>btrfs send -p /tmp/parent_subvol /tmp/incremental_backup_snapshot | btrfs receive /mnt/destination_drive1
  btrfs send -p /tmp/parent_subvol /tmp/incremental_backup_snapshot | btrfs receive /mnt/destination_drive2
  </code></pre>
