CF9, Windows Server 2008 Standard, IIS7, mySQL 5.1.48 community. 

I have managed to get CF to take a database mySQLdump which I was going to run as a nightly cfschedule task, with a server time based lock on the application controlled in application.cfc

That will get me a local copy, but whats the best strategy to encrypt the datadump.sql text file (and what would you use to do so for sensitive personal information) and transfer to an off site location, cfftp?
