SFTP Using new handbook instructions

I’m trying to follow the new instructions listed in the handbook for creating sftp users. I only want to upload my wordpress backup using sftp. Should I just enter in the www-data user into /root/.sftp-config/users.conf? If so should I give www-data user a password? If you could give just a best way to move files into a new wordpress install that would be great, thanks!

If you only want to upload one file, then why don’t you just sudo mv archive.tgz /path/to/wordpress/htdocs? Then chown it to www-data:www-data

I m also stuck. Followed instruction and created for www-data.
I can able to connect sftp but cant access app folder under my site folder.
