What HAS been proved about digital technology is that it is inherently unreliable. If it was reliable there would be no such thing as a backup. If digital cameras were as good as film cameras there would be no such thing as Photoshop.
Nothing's proven. Backups exists first and foremost because of _US_. Human error is the main culprit... ask my client who deleted their database. People can/have thrown away important paper files, shredders still sell well too. What's one of the 1st things divorcees do to their wedding pictures? How many pieces of paper with something important written on it have we all lost? Chances are, we don't even remember that we've had and lost it.... electronic backups are sometimes used as a convenient way to point fingers.
As for film, as Socke already gave us a nice history lesson, nitrate based film was highly flammable, even explosive. There's "archival" for you... kaboom! My FP4+ negs still say "safety film", thank goodness for that. I'd hate to think this pile of negs sitting besides me is literally a time bomb.
As for film not having/needing backups... Robert Capa might have commented differently, his assistant certainly more so. All the movie film from the Normandy invasion was dunked in the ocean and lost. Movies studios were scambling for years to save rotting/decaying/crumbling movie film. Precious footage has been lost forever.
Nothing is immune to fire, flooding, theft and just plain ol' user error. My wife's family nearly threw away 90 year old glass negs from her grandfather. Analogue backups are at least 1 generation removed from the original, so it's never as good, and it's also a pain. That's why we don't bother unless it's very important, hence we use microfilm, photocopiers, digital archival systems for all those paper records.
Want to hazard a guess as to how many irreplaceable digital _and_ analogue records were lost in New Orleans?
Digital backups are so easy that we're stupid not to bother, so much so that it's become 2nd nature to just back it up "on the spot". We don't do it for film simply because it's impossible to make another exact copy immediately. That's why many take along a second backup body and shoot a second shot on a separate roll... there's the backup. In case film is lost/stolen, the lab screws up etc...yup, human error again.
Just because _we've_ changed our excuse from "sorry, we seem to have misplaced your account file" to "the computer seems to have lost your account info", doesn't change the truth. We've messed up, and it's very convenient to blame someone/something else. Since the "computer" doesn't have feelings, it's a convenient scapegoat. If _you_ scratch the film, lose it, destroy it etc, it's plain and simple... it's your fault. How come if you do the same thing to a computer file, it's the computers fault?
I'm not "in love" with digital or film... I'm in love with my wife. I have precious memories on both that I intend to keep, so I'm interested in the upkeep of both types of images.
