Problem/Justification
It is my understanding, that currently Cloud Sync Tasks use rclone to back up data. Unfortunately, that doesn’t seem to back up all the metadata, file ownerships, etc.
Impact
While this preserves the raw data, it makes restoring from backup complicated, as one needs to manually set users, permissions, etc. after restoring data.
If we could mount remote storage through a posixovl fusefs layer, we could use rsync “locally” instead of rclone to fully preserve file ownerships, permissions, symlinks, etc.
User Story
Got plenty of WebDAV-only storage for off-site backup, but nothing that would support rich backups like with rsync. An intermediate layer like posixovl over a WebDAV server would fix this.
Alternative
Given that restic is installed (and used for TrueCloud Backup) and given that restic can use rclone as backend, allow cloud sync targets to be used for restic backups.
What we need in any case, is an efficient way of doing proper backups including metadata onto easily available cloud storage.
