Every qubit might be precious so you would need more matter than the earth to do it (if you wanted to accurately simulate things like when/how volcanos/typhoons happened, so that the memories would be correct).
Possibly the rest of the solar system would be useful as well so you can rewind the clock on solar flares etc.
I wonder what a non-disruptive biosphere scan would look like.
