I've been having people do work for my website a lot recently and I've realized I've been giving out my FTP details a lot, not even knowing if the person is trustworthy. As far as I know, its possible for someone to delete files off your server or mess up your site badly. Correct me if I'm wrong. Before I give out my FTP details anymore to have anyone do work for me, how can I back up these files in case someone decides to screw me? I'm using filezilla if that helps. Thanks guys.
