I wonder how much cine/movie film from the early days has been lost because it was on cellulose stock and how many glass plat photographs found use as green house glass. We seem to have this notion that everything from the past has been saved. It hasn't.
Nothing is permanent except diamond, and that is slowly converting back to carbon.
It's quite easy: make copies using different analogue and digital methods. Convert RAW files to jpgs, which are likely to be usable (orconvertable) when the maker's-specific raws have "vanished" from use. Move any files on from, say 3 1/2 inch floppies before those floppies fade out of use. Print 'important' photos onto paper.
As Stephen says digital techniques have recovered several analogue prints making them able to be seen and appreciated.
By the way, I hope all analogue film has been copied. Otherwise one fire and it's gone, just like the birth certificates and such like lost in Dublin almost a hundred years ago or the records from WWI which were lost when the building they were stored in was hit by a bomb in WWII.
