I'd like to use WinSCP's command line utility or something similar that I can schedule through the Windows task scheduler to grab the folder (plus subfolders/files) from the Linux server nightly and store it on the Windows server.
WinSCP is a free FTP client that manages your SSH transfers between your local computer and a remote server by using secure connections and SCP (Secure Copy Protocol) or SFTP (Secure File Transfer Protocol). All this is done through an interface which is integrated with Windows Explorer, so you can drag and drop files to make transfers. You can also perform typical file management tasks through its default interface or in a dual panel style like that of Norton Commander.
You can easily rename files, copy and delete them, create new folders, or manage multiple files at the same time. It also allows automatic synchronization of folders. With WinSCP, you have a strong and functional free FTP client that allows you to manage remote files securely and comfortably.
