We are restoring some old family photos and movies - all the black and white photos are fine, but the color photos are fading. All the old cellulite film from the 30s and 40s is pretty much dead, it's just disintegrating. There is no long term preservation besides copying. All my digital video on tape from the early 2000s is dead. The early DVDs I burned in 2002-2004 are all dead (due to the organic dye, I guess). Many of the CDs I burned in the late 90s are dead. The most durable digital format I have has been the 5.25" disks, probably due to their ultra low density.
