Zalman FTP client 2010 provides a solution to this problem. The solution provides a unique "change list methodology" to the website. This means that for the first time, with a single click one may view the history of all the changes that were made on the site. It is a powerful and seamless archive engine that automatically backs all data (both to remote and local folders). The solution provides a diff tool which allows the developer to compare the local copy with the remote copy before overwrite occurs.
