Back up of recent modified files

Hi,

I want to identify the files that are recently modified or with in a specified period (15 Days) in UNIX box. After identifying the files should be transferred to windows machine through FTP. The files should be overwritten in windows if it is already available.

Please help...

The find command has the mtime option for doing just that. Then use find's exec or use xargs to iterate through find's results and ftp the files.
