Trevor, with so many films being transferred to a digital medium, supposedly in part to preserve against physical deterioration, what's being done to protect digital, probably equally fragile in its own way, from potential loss due to an EMP or viruses or..... some threat we haven't even thought of, like malicious AI one day, lol?
Know what I mean?
I think despite all the praises sometimes sung to it, digital is fragile and vulnerable to widescale threats. A disaster might destroy a single warehouse and its contents, true, but in some scenarios a motivated wartime enemy or a cyber-terrorist could conceivably erase a worldwide treasure trove of mankind's collected works with a push of a button. And then there's keeping up with changing operating systems that just in my own life have resulted in data loss and memories down the drain.
Is there a backup?
The best backup for digital is to have a full set of film masters - picture negative and optical sound negative - or a so-called "clean" print of a film available: we have a lot of these here.
