I'm not sure that you can preserve all these files for generations to come. Consider that today's filetypes (PEF, DNG, jpgs, etc) are likely to be replaced in the future and if not converted to the new standard at the time the shift happens, you are bound to loose the ability to read them
The same holds true for the media used to archive the files.
