Not necessarily for aliens ... but why not keep a backup in a safe place outside the dangers of earthlings ?

OTOH, I think a sufficiently advanced alien intelligence will be able to decipher the information structures we use regardless of differences in technology. It's possible though there will be missing links in that archive, which will need to be supplemented with a primary secondary and high school curriculim.

What format? I'm eager to know the solution to this non-problem.
