From what I read here: https://community.ui.com/questions/Cant-SFTP-to-Dream-Machine/2b1ab1ce-c93b-4488-bbab-8df2cdbedc94

It doesn't support SFTP. Rclone uses SFTP which is a separate protocol which runs over SSH.

It looks like it does support SCP but rclone doesn't support that yet.

I don't know if you can install SFTP? Maybe you can switch out dropbear for openssh?

hello and welcome to the forum.

i would be careful, not to sync to the desktop folder, as rclone can delete files during the sync.
better to use a sub-folder

Ah, silly mistake on my part.

Since it's an appliance, I'm not comfortable tinkering with it. I'll just have to find something that supports SCP.

Cloning to the desktop was a test. I'll be using a proper folder in production.
