That seems to be kind of a joke, but I heard that the french CNES (spatial agency) is doing some huge database replication between two sites thanks to big trucks carrying the data once a month, because current network devices transfer rates do not allow them to do remote replication through the network. Or maybe the reasons to this method are not only technical but economical. I have no detailed information on this, and it's more a rumour than a verified information, but should somebody know more on the subject, i'd be interested in hearing it.
