To create a FTP backup set, you need to open Xopero and run the Backup set, wizard by clicking on New backup setbutton in My backup sets tab.
In the What you want to backup? field, you need to choose Advanced copy and then FTP from the dropdown list. Name this backup set.
To properly configure backup set in Host field enter the FTP address (like name_server.domain.com), next select the port on which server is running and enter the name and password of user who has permission to log on the server. You can also enter the path to directory in Remote directory field - then will be performed only backup of this folder, else backup includes all server resources.
