Backup on Linux - Permissons

I have Start9 running fine on a RPI 4 9GB but recently had the SD card fail. I re-installed from the Github download and restored the server fine.

Deciding I needed a backup I setup the path to an other local Pi and this looks fine. I get a permisson error. Does this need root user privilege on the backup device, maybe somebody recognises the error here?

Thanks
Garry
