Stop your current cluster. Start a new cassandra instance on the
machine you want to store your data on. Use the sstable loader to load
the sstables from all of the current machines into the new machine. Run
major compaction a couple times. You will have all of the data on one
machine.

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,
