FTP settings to run back up website on different server

Passive mode is being used Brian but i agree the directory is the problem. In linux the default web directory is /var/www/html but as a root user the files wont send to that location. So after reading many guides i set up a var/www/web folder as User Weather so this should get me access but i can only ftp in sftp.
To Linux/Apache experts i’m sure this is basic stuff but i just need the information what i need to do so the WD files will go to /web folder and update the website.
