Can OS X automatically duplicate/backup files after use?

[iMacFarlane]

I know there are some wizards out there that either know how to do this or that it can't be done, so here we go:

I have an external drive I use for Time machine purposes, so I do regular backups. As a developer, the loss of my source files would be devastating. I was thinking it would be very comforting to, in addition to my Time Machine backup, I could copy all of my source to another disk, say an SD card or thumb drive.

Is there a way to automate this duplication of data? Some sort of trick to run in terminal or something?

Mirroring? I've never done this and wonder what solutions exist, besides the obvious: manually copy folder contents from HDD to SD card periodically.

Thanks in advance!

You could use Carbon Copy Cloner to periodically back up selected folders or your entire drive to an external drive. Also, depending on how much storage is required, you could use Dropbox or other online backup services to sync folders to other computers/phones, etc.
