Local storage + cloud storage at once

[rs232]

I have been using local storage long time and it works perfectly.
My media is backed up in the cloud via a rclone/encrypted configuration that allows me direct access to the online copy of the content.
Now I'm tinkering with the possible scenario and after some testing this afternoon I managed to add a second library pointing to the mounted cloud storage which is great.

What I'm after in the thread is some intel on how to have cloud as a backup repo in case the local fails.
Yes, I can add it as an additional library, but this also means double storage needed locally (I'm running this within an LXC), double metadata, double Identifying process, double everything.

Is there a way to use the local library (that was populated based on local media) and simply tweak it to be re-used with this second media repository?

Or is there anything else obvious I am missing here?

Thanks in advance!

On the fly fail over? I'm not aware of away to achieve that within Jellyfin.

What you could do in that situation is use a symlink to point to the cloud storage in place of the original storage. So that it appears to be the same content from Jellyfin's perspective.
