Incremental backups to non-root FTP account?

I’m trying to look for ways to back up websites from my webserver (obviously running CyberPanel) to my home NAS server.

I can see that you can setup an FTP location, but the documentation says it has to be a root user. My NAS does not allow root login so that’s out.

Is there a way to do this without root?

Apparently, not yet. CyberPanel uses SFTP (through SSH) and doesn’t provide a way to use non-root account. It’s a bit lame, so my guess is that it is bound to change in the future.
