Perhaps one of the most perfect Freeware solutions to creating back-ups of your hard drives. BladeBox Iron Edition allows its user to create encrypted volumes quickly and easily without a lot of configuration.

BladeBox Iron Edition allows you to create up to 4 virtual, encrypted volumes, and each can contain up to 30mb of data. The encrypted volumes act like regular disk drives and are invisible until they are activated (mounted) from the password protected interface. The data is transparently encrypted/decrypted on-the-fly, using 256bit AES encryption., there is no need to manually encrypt each file, as it is automatically protected once it is added to one of your protected drive letters.
