    | External harddrives are dodgy...I got one, but don't depend on it.
    | what do you do when it won't turn on, or gives you a "disk not found "
    | error? It happens. 12 CD's are not that bad, you can knock that out
    | in no time. Then make a second set.

    I've had problems so far with one external drive (aside from the Seagate ones
    I got that never worked at all with Linux because they did not conform to the
    letter of the USB standard). Fortunately I have several and make backups in
    triples. I've had issues with CD and DVD media more often, generally a couple
    years after recording them. Really critical files I need to keep a long time
    are also backed up more times to USB sticks or SD cards.

    Anything is possible.
    No kidding.
    Are you a moron or just play one on the Usenet?
    Tape is not write-once.
    Some people don't make that in a month. Glad you do. Still can't
    guarantee it won't fail.

    Aha. So you didn't expect anyone else to ever read it or
    I LOVE back-pedaling!
    That's not a problem. When you break a tooth, you get a crown.
    No problem.
    Until some day some hurricane or tsunami trashes your entire
    computer setup including all your indestructible drives. Don't
    tell me it can't happen. /Anything/ can happen.
    For once you are admitting the possibility that you are human.
    For all we know, neither one of us even exists. And nothing
    Likewise. BTW, what exactly is the "horrid unspeakable crime" of
    telling a stupid person they are stupid? They SHOULD be told!

    Are we done now?

    Glad someone responded because it gives me a chance to say I
    left out "web" before [WWG?].
    Not that many read or noticed it.

    As for the tinfoil hat, it's rather a tired little joke, but
    yes, I admit it, I am psychotic and typing this with my toe

    The /sane/ truth is that Bush won both elections legitimately,
    there were NO gas chambers in Hitler's concentration camps (nor
    did grandpa Bush do profitable business with the aforementioned
    gentleman), there was NO moon landing, and Google stores NO
    personal data ANYWHERE. Oh, and there is NO Echelon either. Or
    US torture camps around the world. After all, God makes damn
    sure nothing bad /ever/ happens.

    THANK YOU for helping me to try and save what little sanity and
    common sense is left in this crazy world.

    Dupe Detector, for finding... duplicates.

    A back up is what you have when you have 2 copies of each photo - one on
    your main storage and one on another storage device.

    If your photos were only on your external HDD then you did not have a 'back

    .. . . keep them in a big book where nobody will look at them from one year
    to the next . . .

  11. Interesting; but having lost a whole weeks trip of photos a couple of
    years back, (from copying to a temporary drive while reconstructing my
    backups - it left two sub-folders uncopied) I need a no-dups detector
    program that tells me that 'this photo is NOT backed up'.

    Has anyone seen the equivalent software?

    "Pappa Joe" made most of the money he used to launch his sons into politics
    by bootlegging, along with other nefarious activities. His sons;

    -JFK - Killed
    -RFK - Killed
    -Ted - In the process of dying a horrible death from brain cancer, many
    years after having walked/swam away from any charges stemming from him
    unquestionably leaving Mary Jo Kopechne to die (while cowardly saving
    himself) in his car under the bridge he drunkenly drove off of in '69.

    -Then we have JFK Jr. - Killed himself, along with his wife and her sister
    in a plane crash because he thought he was better (at piloting) than he
    really was. Other family members were killed in a different plane crash
    years earlier.

    Various and sundry:

    - A still birth, a retard, an amputee, an alcoholic, and on and on. All
    either born, or married into, the Kennedy family.

  15. Wow!

    I am starting to feel like a technology glutton. I am adding to my photo
    archives at the rate of two to four gigabytes per week (I shoot stock and
    fill a four gig card every few days). I can't survive without a raid
    system. I have a terabyte drive in my primary computer, plus two terabyte
    backup drives for photo images alone, and I am constantly "weeding" through
    them to restore space. They are approaching eighty-percent capacity
    already. I can't imagine using optical media as a backup medium, it would
    be an impractical nightmare. I have had *many* cd's and dvd's fail over the
    years, I would never rely on them. I have also had hard drives fail, about
    one every two years, it is like driving a car, sooner or later you get a
    flat. Having three copies of my photo database gives me some sort of
    security. Thankfully hard drive prices are falling as my needs are growing.

    Have you ever sought professional help for your OCD?
    Aardvark, Oct 15, 2008
  18. This part is easy. If you also want to catch duplicates where the file
    has been renamed then you need to check the actual content of the file.
    I would create a checksum, e.g. MD5, and use this as the key identifier
    for each file. Then just run through all the folder with your photos,
    create the checksum for each image found, and store the full name under
    this checksum, always considering, that different files will have the
    same checksum. For a larger collection this will probably take quite
    several hours, but the task can run at low priority in the background.

    Once you got that data then for each checksum if there is more than one
    file you should confirm that the files actually have identical content
    (different content might create the same checksum), and then either have
    a predetermined sequence or interactively ask which of the duplicates to

    If you can do without fancy UI and go with the bare basics then I would
    say in e.g. Perl this is not more than probably 50 lines of scripting at

    Obviously this part requires human evaluation and therefore there is no
    way to automate it.

    Any backup software will do that. However, as others have pointed out,
    this can be a drag for a large collection and other means of backup
    might be easier to use.

    The major advantage of "Photo Library/Mangament Software" is not so much
    the organization of the files on disk but rather the ability to assign
    as many keywords to a photo as you like and then being able to search
    for any combination of those.
    Example: you took that great photo of the Golden Gate Bridge at sunset
    some time ago, but you can't remember on which of your 12 visits this
    happened. If you had marked that photo with the tags 'sunset',
    'bridges', and 'San Francisco' then it would probably be very easy to
    find now.
    And that is exactly the not so secret secret of a good backup. You can
    _NEVER_ rely on any single media or method. DVDs fail, CDs fail, HDs
    fail, computers and HDs get stolen with your precious backups, houses
    get flooded or burn down and your precious backups turn to ashes or
    demagnitized scrap metal.
    You need to take multiple backups on different media and store them in
    different locations. Depending on you level of paranoia maybe even a
    network backup in a different town (I'm sure not many backups survived
    Katrina or will survive the big one in SF, no matter if on HD or DVD) or
    on a different continent.

    I did not follow through all the messages, but just encase; Did
    anyone note that Picasa is not a place, it is a program. The photos
    you see there could be almost anywhere on your computer.

    It's possible to set it up for yourself if you are prepared to enter
    the ancient world of the Command line. Windows still retains the
    'Archive' attribute as part of the file data and you can set or unset
    this either by a keyboard command or by a simple script.

    Once you understand how it all works you will find it is not too hard
    to write a simple script to manage your archives and report on what
    has or hasn't been backed up.
