DNA is incredibly resilient. Stored in proper conditions it is expected last for hundreds of thousands of years. Hundreds of years with today's techniques, which require that it be kept "cold and dry." I don't know the details. See: https://www.nytimes.com/2015/12/04/science/data-storage-on-dna-can-keep-it-safe-for-centuries.html Fragments have been recovered and the genome of long-extinct species such as the Neaderrthal people have been recovered. Of course they were in millions of pieces, but they could be assembled. If you kept multiple copies of databases, using similar techniques and file compare you could reassemble them, I think. >
