Preserving is costly for movies in digital form

Here is the source.

"...To store a digital master record of a movie costs about $12,514 a year, versus the $1,059 it costs to keep a conventional film master.

Much worse, to keep the enormous swarm of data produced when a picture is “born digital” — that is, produced using all-electronic processes, rather than relying wholly or partially on film — pushes the cost of preservation to $208,569 a year, vastly higher than the $486 it costs to toss the equivalent camera negatives, audio recordings, on-set photographs and annotated scripts of an all-film production into the cold-storage vault."
