"Root->Backups" whats this? this isnt a directory format, simple answer you need to log in using a command line ftp to your ftp server, look at the directories it gives you and work out the path relative to where you want to go and then change to it.
Did I just hear "You gotta help us, Doc. We've tried nothin' and we're all out of ideas" ? Is this you? Dont let this be you! I will put in as much effort as you seem to.
