Encrypted System Backup
I would like to encrypt my entire disk offered by a fresh Ubuntu install as described here.
However, my current laptop has too many configurations that I do not want to re-do. I would like to backup the entire system, format the drive, re-install Ubuntu with the disk encryption option, and restore all files and configurations.
How hard is it to do this and what should I be careful about? Can I backup and restore as described here?
