    For example, if the backing planes is xF0 and the backing pixel is x75, can
    the server, when it saves into the backing store save all planes, and then
    when it restores from the backing store restore all planes?

Yes.

    The real issue is what does the phrase "free to save" in the protocol spec
    really mean?

That means it has the option of only saving the specified planes, but it is
not required to save just those planes.
