Anybody figured out a way to completely backup the 770?

In a similar way that you'd use ghost, acronis, clonezilla etc to take a complete image of a system. In the few hours I've owned a 770 I've got loads of applications installed and made a load of changes (kernel image etc) which I clearly don't want to have to do again in the event I kill it.

OK the kernel change will always need to be handled by the flash app, but the rest should just be either dd'able or?

Ideas?

What do people do?
