How to avoid obsolete storage hell
Don't get suckered into using a backup medium that your next computer won't be able to read.Rafe Needleman April 13, 2005
In 1987, I was a dBase II programmer for a structural engineering firm. The computers of the day weren't terribly reliable (some things don't change), so I backed up my work regularly onto 10MB Iomega Bernoulli disks. I also thought I might want to check out my work at a future date, so I filed away the disks.
Recently, I uncovered these disks. They're rather quaint now -- massive 8in.-by-10in. plastic cartridges holding flexible disks inside them -- but they were the height of reliable backup at the time. Today, they're utterly and completely obsolete, best used as serving trays for drinks. Along with the Bernoulli cartridges, I uncovered more old Iomega disks: a few 44MB Bernoulli Box II disks (mini-versions of the original -- only some 5in. across), a solitary 1GB Jaz drive cartridge and about two dozen Zip disks of the 100MB and 250MB variety.
Am I a sucker for media that's doomed to become outdated, or is it just that I fall for the siren call of Iomega? In truth, all media eventually becomes obsolete (want to buy my old Joni Mitchell LPs?); it just seems that some wither and die faster than others. Which brings us to the question we should all be asking ourselves: what's going to happen to the CD-ROMs and the DVD-Rs we're using to archive our precious data? Are they doomed to becoming useless, except as coasters, too?
Putting aside the issue of whether DVDs will be readable at all in 20 years (the metal oxides in DVDs can rust), there's the simple progression of technology and storage at work. At one point floppy disks were ubiquitous, but hardly anybody uses them anymore, because you can hardly fit anything on them -- a 1.4MB floppy disk can't hold a single uncompressed digital photograph from today's advanced cameras. Even an 8.5GB double-layer DVD is doomed to the same fate.
