Simple PERL or PHP script to do SFTP transfer

I have a Linux/Cpanel server which runs a backup every 2 days. The backup [login to view URL] ile is around 30GB. I need a simple PERL/PHP cronjob script that will be set to run every 2 days to check what is the latest 30GB file (you can checking all 25+ GB files in the directory "/home/myusername/" and taking the file which is modified less than 2 days ago). Upon detection - Launch SFTP from this current server - Connect to another Linux Barebone Server (no cPanel, this is just SFTP access). - Transfer the file over Need an email to be sent on either one of these event: - Successful upload of the backup file - Any failures
