Please note that I am not using Docker Volumes for this, as we have a custom backup solution which backs up all the folders inside the ‘/data’ root folder.

I looked at the other thread you have provided. You have explained about the Docker Volumes. Since it was working fine for me till last week or so, I tried deleting the containers and re-pulling the latest one and restarted the server. Same results.
