Rsync Add-On has stopped working

Hi all, I was under the impression that I was using the Rsync add-on to copy some files (e.g., /backup and /config) to another machine on my lan. Today’s release prompted me to reexamine my backup policies and I notice that Rsync seems to have stopped working some months ago. I haven’t touched the configuration or anything, and there aren’t any complaints in my logs, but absolutely nothing is showing up on the other end. This is my config:

private_key_file: /ssl/rsync/id_rsa
username: root
folders:
  - source: /backup
    destination: /media/backup/homeassistant/
  - source: /config
    destination: /media/backup/homeassistant/
remote_host: 192.168.50.214

I checked (using the Terminal & SSH add-on) and the private key is still there and still works to ssh to the host at that address (e.g., ssh -i /ssl/rsync/id_rsa [email protected]). The log of the add-on just says:

[16:33:57] INFO: Use private key from null
[16:33:57] INFO: Synced all folders

Is this add-on still supported? I checked and I believe I’m using the updated repository. Anything else I can check?

Just to close this, I must be doing something wrong, but I can’t figure it out. I’ve uninstalled the Add-On and just use a Samba share instead to achieve the “2” (two media) in the 3,2,1 backup strategy.

Still, I’ve been using rsync for must be a decade now and I’d be curious what I did wrong. Manually running rsync works fine. This add-on seems to be doing nothing, with no errors or warnings.
