@nebulon I appreciate your advice. The backup server is not on the same location as the cloudron server. It isn't even on the same country (like I do with all my backups).
Maybe I wasn't clear: the server has an OS disk (nvme) and a HDD for backups. The mount I showed is the HDD disk mount. It was just to check if any filesystem mount options were needed to improve performance.
Thank you all.
