Clone Hard Drive and Disk Encryption

view story

http://ubuntuforums.org – Two quick questions for hard drive management: 1. What app can I use to clone my hard drive with that would be similar to Carbon Copy Cloner on the Mac (in order to make a bootable clone)? 2. I'm using FileVault on my Mac to encrypt my Mac's hard drive. Does Ubuntu CE offer something similar built-in or is there something I can install for encryption? Thanks! (Hardware)
