GoodSync

GoodSync will automatically backup and synchronize all your important files so you never need to worry about losing your emails, precious family photos, contacts, MP3s, and financial documents. GoodSync works locally - between desktops, laptops, servers, and external drives, but it is also capable of backing up and syncing files to and from remote servers using FTP, SFTP, WebDAV, and more. Our latest version allows synchronization with Windows Mobile devices and PDAs.
