Backups "Append to Path " doesnt work

So my problem is that :
i have a server which i backup to an exteal ftp server.
the problem is that i use the "Append to Path" but it never really goes to the PATH specified,instead it changes the NAME of the files to
Sunday.user.user.tar.gz
instead of going to the PATH of /home/backup/Nameoftheday/user.reseller.tar.gz
it just create the backup at /home/backup/Nameoftheday.user.reseller.tar.gz

any help will be appreciated

thank you!
