Nothing? My digital storage beats your film archive. It also deals with increasing entropy nicely. Speak for yourself.
My screens beat your paper. Again, speak for yourself. Also, it doesn't need to be beaten because it has nothing to do with the product, it's just a presentation medium. I can scan and hex-dump a negative onto a t-shirt and scream "nothing beats t-shirt" and that would be just as absurd.
Use proper file systems like BTRFS or ZFS.....you need checksum verification software (like hedge) because you have bit rot problem (data corruption), .....
That's alphabet soup to me, and I assume many others. I don't want to derail this thread further so I'll check for other threads on backup strategies. I think my strategy is sound but who knows.Use proper file systems like BTRFS or ZFS.

I'd be very interested in a scanner that:
1) uses a CMOS or other high quality full frame (rather than line) sensor;
2) employs optics that are truly optimized for flat field performance at the magnifications required for the variety of different magnifications mandated by by a variety of different film formats;
3) includes a reliable, consistent output light source (like electronic flash) that provides continuous spectrum light of appropriate colour temperature;
4) includes filtration for the light source to match the light to the design specifications of the mask in C-41 negative materials;
5) provides useful, flexible and efficient provisions for handling sheet film, complete rolls, and short strips of roll film and mounted slides, in a manner that ensures film flatness;
6) includes provisions that prevent interference from ambient light, and help remove/minimize/eliminate dust;
6) includes software protocols that are exactly matched to the sensor and light sources employed - both for positive and negative films - and provides file output that suits commonly used image editing software - not just Adobe products; and
7) is small and attractive enough to have out in open view.
In order for the optics to be of high enough quality, I accept the fact that it may be necessary to have multiple lenses on a turret or sliding mount.
In order to maintain the consistency of light output and sensor response, it may be necessary to include calibration hardware and software.
Do you think it would bee more than $300.00?
Actually you don't want continuous AKA "white" light.
Electronic flash.

I like digital photography, I have nothing against it. It just so happens that I enjoy using film cameras, not digital cameras, in spite of seeking a digital end-product - for a variety of reasons. Price, handling, ergonomics, the beauty of the process, the beauty of the results, the simplicity of the tools, and so much more. For example, I love shooting and developing black and white film and the results I (and I stress `I') get from a hybrid workflow (film camera+film+self-development+self-scanning) are way closer to my taste - with little or no post-processing - than what I (and I stress `I') could ever get with a DSLR followed by greyscale conversion of some kind.
So, to go back to scanning: it follows from the above that not everyone who scans uses scanning as cheap way to obtain digital 'contact sheets'. I, for instance, try to pursue the best scanning results I can get, and therefore am interested in great scanning devices. Therefore it makes sense to discuss scanning technique, scanners, DSLRs and any other devices that might fit the bill.

So if you, or anyone interested in this matter, would like to start a discussion I'd be all ears and be happy to contribute. Apologies to OP for the slight tangent.
Halogen is continuous. That's what counts. No big valleys and not sudden peaks.Halogen is a lousy example of of "continuous" light-- it's very low in the blue end of the spectrum, and heavily biased towards red. The higher CRI LED's have more blue (although they typically have a "notch" in the blue/green range) in their spectrum.
Here's a decent comparison:
Use proper file systems like BTRFS or ZFS.
Intentionally so.That's a pretty tall list of requirements.
filesystem on the NAS device is not relevant if corruption is caused by the host OS.
Use proper file systems like BTRFS or ZFS.
Of course, rebuilding most RAID's (or storage pools) requires stressing the ever-living crap out of the array, as you have to rebuild the entire array every time you replace a disk.

If you include the addendum in my subsequent post, it represents together all the things that I figure matter when it comes to digitization.
I included all that on the list, because I see so many posts that talk about one thing that matters, but imply that that thing makes all the difference.
@Adrian Bacon advocating for (even excellent) filesystems is a terrible advice in the context of backups! People just don't realize how utterly pointless filesystem integrity is when it comes to backups. In fact, part of me even wants to recommend chaos-monkey style hardware + filesystem losing data on purpose, just to force healthy backup habits.
@grat In-memory corruption happens all the time! Google published the paper on this a while ago analyzing their datacenter failures where they presented a probability of a bit flip per GB of RAM over time advocating for ECC. You can probably find it even now.
Ugh... "in 25 years" argument again... One would think an introductory course in statistics would cure that. First of all, a dataset of one is not enough to make conclusions. Secondly, I guarantee you that you've had more than one corruption, it is impossible for you to know the state of every byte on your computer.
Do you guys back up every image you take, or do you edit and delete your rejects? How many images do you have backed up right now? How many prints do you have saved?
