Yes I'm sure the tech is not there yet and I'm not saying make a hard copy and send it to space.... but how far are we off? Hundreds of years or decades? Is there an iterative process... perhaps satellites at first (since landing is generally complicated). I guess it also depends on what you want to store and what you use to store. There are crystals that could store data for pretty much eternity [1]. The problem with shoving stuff in a hidden salt mine is that no one (ie aliens, future people etc) will know where it is where as on the moon or satellite you can effectively have a much more salient sign of here is the data (ie what is worse the data is destroyed or the data is never found?).
