Who are we saving it for? That level of black swan will end humanity and … well, that's it. We won't need the info. Any species that arises after us will likely follow different paths of development. Any species receiving the information would have to be at a very specific point of development in order to even understand what they received. If we're saving it to aid future generations of humans understand us and/or rebuild or something useful, then by all means, save it. But if we're just trying to prove to the universe that we existed, I don't think the universe cares one way or the other.
