    guys…
    you need to look at this…

    https://code.google.com/p/tungsten-replicator/

    This enables multi-master replication and/or moving/syncing data to other db’s

    Is this data moving towards a “Big Data” moment ? maybe it should be in hadoop ?

    regards

    Hi ally,

    The only problem with sending to multiple servers is that if a path is down between the client and a server, the data between servers will get out of sync because the client wont be able to update them all – so you would still need a method by which to keep the other servers up-to-date.

    I’ve use this before…

    https://code.google.com/p/tungsten-replicator/

    to keep MySQL backed RADIUS servers in sync in a multi-master config.

    In Australia we haven’t really done anything nuclear past a couple of small reactors for science & medical in Sydney at Lucas Heights.

    That being said we have a waste dump in central & northern Australia…

    and some of the biggest uranium mines on the planet…

    So while high level radiation from a nuclear accident may not be a concern, the potential exists for dust storms to bring uranium into populated areas.

    So.. thinking about how to achieve global replication we need to know what DB underpins the master server.

    Once we know that, we will begin to understand what’s possible.

    So the big questions are …

    What is the DB ?

    I suspect its MySQL

    How much space per record is consumed ?

    Have you already extrapolated the db space required for the deployment of say a 1000 units worth of data for a year ?

    If it is MySQL then replication can be done securely in many ways.

    regards
