Once you get all of the data on one machine you can then
flush/drain/compact shutdown the single node and then take the data
folder off that machine and back it up. Then when you get your new
cassandra cluster setup you can use the sstable loader to shoot the data
from the backup into the new cluster.

Hi Jeremiah,
The thing is I will send the data to a massive storage facility (I
don't know what's behind the scenes) so I won't be backing up on one
machine where I can install Cassandra. Does the sstable loader work
just for copying data from a Cassandra cluster to somewhere on a disk
where there is no Cassandra instance? If not what is the best way/tool
to achieve that?
Cheers,
Alexandru

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,
Alexandru
