    I have several hundred ripped movies on DVD-R medium. I would like to
    keep these for many years to show my sprogs etc

    I know that optical media cannot be relied upon for more than a few

    What should I back them up onto for longest life ? Tape ?

    Try buying the original copys on DVD: They should last much longer.

    Interesting question though, I have loads of edited DV footage from just
    before my daughter's birth to date, 3.5 years and counting and I've been
    wondering similar things.

    Make a copy every few years onto whatever the current mass-storage
    medium is, while you still have a drive that can read the previous
    version. I suppose that ideally you should be checking the media every
    so often to see what the error correction rate is, but any sample you
    check may not be representative of the worst example and just by reading
    the disks you could be causing additional errors, and you should be
    checking that the drive still functions but each spin-up is one step
    closer to failure.
    Transfer the data to papyrus scrolls and store them in clay pots in a
    cave in a desert somewhere.

    yawn :

    I think the best solution is a large external hard drive.
    They can be bought for 60 pounds (120 dollars ) for 500 GB.

    That should - hopefully - last 5 to 10 years.

    Putting all your eggs in one basket probably isn't the smartest move
    when it comes to reliable backup solutions. At least with removable
    media you have the chance to try different hardware rather than running
    straight to a data recovery specialist.

    But that doesn't work reliably, you'd have to be able to factor in
    sandstorms, global warming, flooding (hey, if the ice caps melt..)
    Definitely too impermanent and any transcription errors could make
    recovery difficult. Papyrus is expensive and have you any idea how much
    of it I would need for 60 hours of DV footage?
    Surely the point is that the external disk is taken off site so there
    are 2 copies of the data? Apart from that everything you say is valid.
