In my weewx.conf I have a section:
[[RSYNC]]
enable = true
server = XYZ # It's only identifier needed for file described below.
Can be anything, for example MY_SECRET_SERVER
path = /path/to/files/on/my/remote/server # for example:
/domains/my-domain/public_html/pws
And in /root/.ssh I have file named simply 'config':
Host XYZ
HostName my.remote.server.com # HostName can be also direct IP address
Port 45678 # Port to SSH if not standard 22
User me # name of your user on remote server
And rsync from inside of Weewx works in my case.
