When you need to back up, restore, or migrate data from one Docker host to another, volumes are generally the best choice. You can stop containers using the volume, then back up the volume’s directory (such as /var/lib/docker/volumes/<volume-name>). Other alternatives, such as bind mounts, rely on the host machine’s filesystem having a specific directory structure available, for example /tmp/source on UNIX systems like Linux and macOS and C:/Users/John on Windows.
