Unfortunately their new backup support forces encryption; that makes sense for cloud-based backups but not for local (NAS etc.) ones. Requests for that just get replies to do it with manual backups the old way.
Because that means I need to manage the encryption key (which is a file, not a password). It makes it harder to do restores because I need to dig out the key.
I don't have anything I care about in the Home Assistant install to need encryption; if you have access to that you are already in the network, same as the actual running device.
