I think there are worse ideas than cloning your data into a population of tardigrades using an error-correcting code, and then dehydrating them into the tun state. Not nearly the density of raw dry DNA (which itself can be stabilized using trehalose or PVA) but tardigrade tuns can resist harsh environments for ~millenia.
