Create a Dockerfile like this:

FROM your_image as initial
FROM your_image_base
COPY --from=initial / /

your_image_base should be something like 'alpine' - so the smallest image from which your image and its parents descend from.

Now build the image and check the history and size:

docker build -t your-image:2.0 .
docker image history your-image:2.0
docker image ls

docker run --rm -v some_volume:/volume -v /tmp:/backup alpine tar -cjf /backup/some_archive.tar.bz2 -C /volume ./

And to restore it, just run:

docker run --rm -v some_volume:/volume -v /tmp:/backup alpine sh -c "rm -rf /volume/ /volume/..? /volume/.[!.]* ; tar -C /volume/ -xjf /backup/some_archive.tar.bz2"
