I'd like to start a discussion about this post. I like the idea to store the metadata in a database
This would be a great feature for my Szenario. I use rclone mount on some servers. So each server is looking for the meta-data on the mount. In a very dynamic infrastructure, I could back up the database and restore it to the target server so that the server does not have to create a new database. Moreover, this process could be made even more efficient with a central database.
