I’ve ever welcomed comments on this site, and sometimes the comments, collectively, are meliorate than the example post, but I seldom only throw up a person and unstoppered the story to another speakers, depending on commenters to wage the aggregation and interest. But I conceive I’ll essay that now. The occurrence is a discourse from an “old pro,” histrion S., that I can’t answer:
I feature your place regularly and savor it immensely. I hit been a favoring for 25 years, employed mostly for non-profits.
I am visaged with a hardware issue. I hit strung unitedly pairs of hornlike drives (6 sets totaling most 7 TB to date) that support substantially for short-term storage. What do most grouping do for a long-term solution? I hit heard so whatever options, I am meet confused. Do you undergo a place or unification that haw help?
What most this? What does the forthcoming of archiving countenance aforementioned for digital images? The archiving of prints, slides, negatives, and another tralatitious media, a sub-specialty of essay conservation, has a well-established power and acknowledged practices. But what crapper you do now, or what do we domain to attain in the nearby future, for long-term, imperishable archiving of our digital media?
Does anyone undergo what actualised archiving institutions are doing? Is anyone alive of the land of acknowledged practices among conservators?

Featured Comment by Craig Norris: “This person has been actively on my list for the time decade years, ever since it became my domain to impact on the difficulty for TV stations (my another occupation right photography). Video creation typically consumes up to 70 gigabytes for every distance of broad definition transcription that is transcribed in whatever modify of shut file. Even with low-end transcription formats aforementioned HDV, using such deeper degrees of compression, it ease requires something in the visit of 11GB for apiece distance of transcribed material.
“In ease picturing the filler of our difficulty is whatever visit of magnitudes small in cost of unconditional accumulation hardware consumed, but the domain to dependably preserves the accumulation indefinitely is no inferior essential and no inferior difficult.
“To intend straightforward to the discourse display by Scott, I crapper designate on the fact that TV stations today are already using or hunting to ingest LTO accumulation tapes as the essential digital magnitude hardware medium. The underway edition titled LTO-4 has a autochthonous power of 800GB per enter cartridge.
“Linear accumulation enter cartridges aren’t beatific for day-to-day haphazard access, so the ordinary training is to ready the astir touchable on RAID hornlike round arrays, and to backwards it up regularly to LTO-4 tape, which is commonly housed in robotic auto-changing libraries containing hundreds or modify thousands of enter cartridges. Next assemblage module wager the launching of LTO-5 tape, with threefold the power of LTO-4.
“The above-mentioned resolution existence adoptive by TV stations isn’t economically viable for the cipher photographer, eliminate for the fact that a standalone LTO-4 enter intend crapper be utilised to back-up the multi-terabyte hornlike round hardware bespoken to one’s workstation.
“According to my stylish investigate on behalf of TV stations, and in the hunt to cipher my possess accumulation hardware difficulty at my studio, blu-ray round is aborning as a applicatory accumulation hardware medium. With the newborn dual-layer edition substance 50GB of power per disc, and an estimated accumulation ridge chronicle in the visit of note years, blu-ray round is probable to be the incoming accumulation archival employ that I compel for my digital picture archives.
“Supporting my comments above is the attending I prefabricated a some life past when I was hired to picture the NBC Universal athletics facilities in Beijing. I saw NBC transcription a rattling super equilibrium of the Games programme on Sony’s XDCAM HD info discs, a near relation of the Blu-ray accumulation disc.”
Featured Comment by Stephen Barnes: “Information Management is my punctuation job, and the digit abstract I’ll feature is that it’s meet as unclear for the professed archivists as it is for the photographers.
“I’ve worked with the National Archives for Scotland, Public Records Office for Northern Ireland, and The National Archives in England, and hour of them hit some conformable method or approach.
“The prototypal difficulty is deposit longevity. Any images we necessary to beam to them were place onto MAM-E [MAM-A in America] Gold DVD disks which hit an estimated 200 assemblage possession period. I personally ingest Kodak Professional Archival DVDs. All images are then derived onto a SAN which retains binary copies of apiece enter on-line. Finally, this SAN is hardback up to tape. We thence hit threesome assorted technologies on which images are retained.
“If a profession looks aforementioned it is feat to be superceded, we designate every accumulation to the newborn employ as presently as possible, to attain trusty we hit the knowledge to feature the data. Old technologies (eg. disc disks, modify VHS!) are archived along with a sort of employed devices. (There’s no saucer in archiving something if you don’t undergo if you’ll hit a amount in the future!)
“The aforementioned is genuine for formats. While it doesn’t countenance aforementioned JPG/TIFF are feat to go absent we would modify to deciding formats (PNG, PDF, DNG etc) to minify risk.
“What this every effectuation is that for huffy and historically essential aggregation we hit up to quaternary copies of the aforementioned accumulation on apiece of threesome media. That’s 12 copies of our images.
“But the professed archivists hit a desirable media for daylong constituent preservation—silver halide prints.”
Featured Comment by David A. Goldfarb: “If digit wants to preserves images for the ages and not rely on accumulation transfer, I concord that the resolution is to attain the prizewinning archival prints digit crapper attain and accumulation them according to the acknowledged archival practices for essay media. An essential generalisation of archiving is that a long-term deposit should be ‘human readable’ if possible.
“I met a student erst who had domain for the deposit of an essential amount in U.S. external policy. He had an duty flooded of 8″ floppies, the example machine utilised to display them, and a Brobdingnagian IBM machine the filler of a drink plateau that could indicant files from this computer. Sometimes that’s what it takes to preserves something worth protective in digital form. I venture by now, if he hasn’t migrated the accumulation digitally, he’s belike printed it all, and scanned and/or microfilmed it.”
is, in my opinion, the best aggregation of its
