I think an electronics copy is the nearest thing to the original. For me, we 
 information and nothing more. A QND reader can get as near as we will from
 any quantum defined state of an object and two objects with identical quantum
states are indistinguishable, even in theory.

Even an imperfect copy will be better than anything else. Such a copy would be
motivated to recover the missing information and so is the best insurance
 for getting it, in uploaded form or nano repair if this is possible.

 The natural laws in brain are electro-chemical ones, they rest upon
electromagnetic field and quantum mechanics. Both subjects are
 well known (even if there are arcane interpretations of quantum mechanics).

So I think we can indeed conceive a fairly good simulation.
There is another problem: I don't think reanimation probability
grow with time. Too much problems can destroy a frozen body.
The sooner you get out, the best, even in an electronics device
linked to a biological "interface" having nothing in common with
the human species.
