How to reduce disk space usage

[dberardo-com]

Unfortunately i have noticed that the "propagated-mount" folder insider the /ar/lib/docker/plugins directory basically mirror the remote host directory. This causes a lot of disk usage on the local host machine mounting the volume. I assume this is done for caching purposes, but is it possible to avoid this?

And could this also be the root cause of the data loss caused by removing the volume mount, as highlighted in other issues?
