Archiving photos for long term storage from a digital camera

[Marquoz]

I had an interesting conversation with my father over the weekend because he purchased a new digital camera, and figured out a problem. Basicly how do you store photos from a digital camera for 20-30 years? Burning it to a CD isn't exactly viable because I know they degrade over time because of the burning process. Also storing on a hard drive isn't exactly 100% safe either because hard drives do crash. Storing on an external drive that is rarely used seems to be a safe solution at first glance, but then you have the issue of constantly moving it over 20-30 years and the chance of it being lost/damaged irreperably. Pen drives are out of the question because of the limit on read write before they burn out. RAID arrays have a fatal flaw as the controller can fail. The thought of storing it online was mentioned, but can you guarantee the company will be there 20 years down the line?

Is printing them out still the best way for long term archival solution? Or am I missing something with the changes in technology?
