Hello everyone.
 3 node Cassandra 0.8.5 cluster. I've left the system running in production environment for long term testing. I've accumulated about 350GB of data with RF=2. The machines I used for the tests are older and need to be replaced. Because of this I need to export the data to a permanent location. How should I export the data? In order to reduce the storage spac I want to export only the non-replicated data? I mean, just one copy of the data (without the replicas). Is this possible? How?

Cheers,
Alexandru
