Ok Professor, better put your tinfoil hat on. I'm not talking Flickr or Smugsmug or whatever other dinky free thing you read about in last week's rag. I'm talking actual cloud based backup solutions. Anyway, you probably know all about these too so no need to explain further. :confused:]
Actually no, you clearly have no idea what you're talking about.
Back up solutions for all digital data can be a real PITA. Paper tapes, Hollerith cards, tape [print through and fade problems], memory drums [fade problems and now parts], metal disks, floppy disks, ... nothing is perfect and they all require due diligence. Even used SECDED.
Cloud based solutions unfortunately are subject to hacking and theft. Further if you read the contracts, you loose your copyright privileges and control of the images. Suppose you took nude photographs of a girl friend. Later you marry her. Both your careers take off. Someone finds those photographs and spreads them all over the internet. Do you think this will cause you a problem?
The only cloud solution that is worthy of being considered would be one that is a server farm completely under your own control. At this time that is hardly cost effective
versus existing analog methods.
Analog also has its problems: water damage, fire, dust, scratches, ... RC paper is not as archival as fiber paper. Color prints are less fade resistant that black & white but keeping them out of the sunlight and using UV glass helps. Some slides from the 1960s are showing signs of fading [Dynachrome and some Anscochrome, not Ektachrome nor even the dreaded Kodachrome].
Neither analog nor digital are completely archival, but generally in the long run analog is more archival than digital today.
Yes, I know what I am talking about and it is based on a lot of experience, analysis, physics, engineering and science and not on what I had for breakfast or the way I would like the world to be.
