On a laptop it'd be nice though, but Saad Kadhi has already commented on

Why can't you do normal backups with encrypted FS?
If the encrypted file-system looks like one big binary file I can
understand the problems, but shouldn't it be possible to design the
system so there's one file per inode for example?
Writing an encrypted file-system is *way* over my head, but I'm intrigued
by the idea and looking for enlightenment.

Have a nice day
