There are four challenges to deal with in preserving memories over time:

  • Physical decay of the medium. Most digital storage media don't last as long as paper, or even photo film.
  • Physical loss or damage of the medium. With each passing decade the chances of fire, flood, theft, or accidental loss increase.
  • Future access to the medium. Those finding it need to have the right equipment and software to read it.
  • Navigation of the data. Those finding it need to be able to know what it is, what it means, and to find their way around it.
