Besides the off-planet complete database-backup I envisioned, another intriguing conceit would be to start on the process of transcribing wikipedia onto vellum with non-corrosive and persistent ink (I don't think there are enough stone tablets, or even clay for tablets to ever suffice, but vellum is clearly unlimited, if a little slow to come by).
3 million clay tablets would be possible and vellum and the like tends not to last to well in the long term outside some limited climates.
