Full backup problem and getting Full Backup off HAOS to my network

I have the Samba Backup addon, but it’s not a full backup, and I can’t set what it backs up.

With settings → Backup I can make a full backup, but I don’t know how to get it off my Odroid and onto my network.

Also I saw an addon called Samba Share but I couldn’t get it to connect, even though the Samba Backup addon seemed to have no problem finding the network.

I just now tried to make a new full backup using the System → Backup function, got an error:
