How is a backup into the cloud or hard drive is a sub-optimal solution.

  HDD last only a few years up to 10-15y. SSD last even less years. DVDs last 10-20y. Cloud... it depends. Old school tapes last 20+ years.

    While I am in doubt with the numbers, I agree with the trend. Writable DVDs last sometimes even less years, since they are produced so cheap. There where the MO-Drives, that really lasted many decades, but they also vanished. Best solution currently are the old-school tapes, since they are created as real backup-solution. Trouble is, that when you want to buy a current drive (with enough data density) you will have to invest a stack of money just for the drive. Also the equipment and tapes are seldom sold for consumers. I looked up some figures ... and one cartridge currently costs half the sum of the same hdd space (consumer drives). So even the cartridges are rather costly for consumers.

      It's my understanding that writable DVD technology is so marginal that even the best media, MAM-A Gold, isn't worth trusting your data to, although by now we ought to have long term info on how good or bad it is in practice. Hmmm, and it looks like MAM-A Silver and Gold CD-Rs are what we're going to have to switch to. Previously they weren't judged as really needed given the quality of Taiyo Yuden CD-Rs, but if the latter aren't available....
