successful digital longevity faces  at least three competing risks: 1) 
physical media deterioration or failure, 2) hardware interface 
obsolescence and 3)  software format obsolescence (both image file 
format and filesystem standard).  Any one of them by themselves could 
relegate your images into oblivion.

i think the simplest metaphor is to imagine a clock that starts every 
time you lay a bit anywhere, on a hard disk, an external drive, a DVD, a 
flash drive.  When that clock shows 5 years has elapsed, at least one of 
those three risk factors is going to be sufficiently elevated that 
prudence would demand a new generation copy on a contemporary medium and 
contemporary format.

the paradigm is different from the "cool, dry, dark" archive model that 
worked so well for analog.  in digital we need to "stir the bits" by 
copying to keep them fresh.
