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