hey guys, I'm trying to take = backups of a multi-node cassandra and save them on S3. 
My idea is simply doing ssh to = each server and use nodetool to create the snapshots then push then to = S3. 
So is this = approach recommended? my concerns are about inconsistencies that this = approach can lead, since the snapshots are taken one by one and not in = parallel.  

nodetool -h 10.10.10.1 snapshot = thissnapshotname

Any help would be = appreciated.
