Like many users, I'm cautious about losing data. My primary drive uses the built-in backup utility in Windows 7 to backup onto a pair of larger mirrored drives. I want to a way to automatically copy/synchronize that backup onto an external disk daily. I rotate that external drive out every week or so to an offsite location.
Currently, I manually wipe the external drive and copy-and-paste the backup from the mirrored drives. It doesn't seem like I should have to do it manually, but rather should be simple to set up automatically. What is the best way to achieve my goal?
