Backup VBS Program

I need a simple vbs program that can work as scheduled task in MS Windows. The main function is to download a specified directory with all sub-directories and files from FTP/SFTP and save it to a local folder. It is suggested to use WinSCP as the FTP client to connect the FTP Server. The program should have the following configuration in code. 1. Path of the local WinSCP exe file 2. FTP username 3. FTP password / path of private key (for ssh connection) 4. FTP Adress (e.g. ftp://[login to view URL]) 5. Download Directory (e.g. /var/www/html) 6. Local Backup Folder (e.g. c:\backup)
