It's pretty simple, really. I'd use a mind scanner to map your neural connections while you're asleep, effectively 'saving' your 'progress'. It's mapped to a network like those in Kurochi and Shinoko. Should you die, that copy would be copied to the brain of a clone held in stasis, as well as attaching your soul to your new body via the tether, and you'd be revived.

If you wanted a step farther, we could probably install a device in your skull to give an 'impression' of what's happened since your last 'save'. It'd probably be hazy though, like a dream, but it shouldn't overwrite anything, and would be a lot safer.

Of course, it'd take months to grow a proper and stable clone, but even then you'd be more or less safe... you'd just stay in the copy until the new body was ready.
