I'm not sure where to post this so if some one can direct me to thread about this that would be great.
This fall I attended an educational session in our local camera shop that was given by a Canon rep. I will try and quote him as directly as I can here: He said that he highly discouraged backing up pics on an external hard drive since they have moving parts "that eventually crash and fail" (this just happened to me this week so I understand that one too well). He said that online storage is not really recommended either because 1) most sites have hidden in the "small print" that they now own your pictures and 2) just how long will a site be up--you can't guarantee longevity of a site! He highly recommended using DVDs to store your prints and then launched into a speech that not all DVDs are equal either. He said that the DVDs/CDs that are mass produced start to lose image quality in 3-4 years. He said that, and I believe he said "only" brand that has proven to have lasting quality (100+ years) is Delkin. Now that I've personally had an external hard drive crash this week I would like to go to DVD myself and am wondering if it's worth the pricier Delkin brand (runs around $80 on Amazon currently). OR, do you have other advice for me?
