+  How to migrate a data volume
+---
+
+Here is how to migrate a data volume between two of your hosts. A rsync of the proper `/var/lib/docker/volumes` subfolder would work just as well, but is here a fun way to do it with docker and pipes :
+{{< highlight sh >}}
+export VOLUME=tiddlywiki
+export DEST=10.1.0.242
+docker run --rm -v $VOLUME:/from alpine ash -c "cd /from ; tar -cpf - . " \
+| ssh $DEST "docker run --rm -i -v $VOLUME:/to alpine ash -c 'cd /to ; tar -xfp - ' "
+{{< /highlight >}}
