Creating backup using luckybackup following tutorial from spx labs

Hi!

Im following this tutorial - https://unraid.net/blog/unraid-server-backups-with-luckybackup

I'm trying to set up a backup from my main server to my backup server using the blog above but I'm having a bit of trouble. When I run the line:

scp /root/.ssh/id_rsa.pub 192.168.1.9:/root/.ssh/

I get an error saying port 22: Connection refused, am I correct in saying in mangement settings within webGUI I need to set use SSH to yes should fix that issue or is there something Im missing?

I also had I another question another user mentioned to save the key under /luckybackup/.ssh/, in the next step of the blog when he copies the key to the backup server would I enter in the following line?

scp /luckybackup/.ssh/id_rsa.pub <backup server IP>:/luckybackup/.ssh/

As I dont have luckybackup on my backup server? Or would it just create the directory?

Apologies I did also reply to the forum within this thread -

but seems it might be a bit old and hidden
