Hi Varun, yes you are right - that's the structure that gets created. But if I want to backup ALL columnfamilies at once this requires a quite complex rsync as Vladimir mentioned. I can't just copy over the /data/keyspace directory as that contains all the data AND all the snapshots. I really have to go through this columnfamily by columnfamily which is annoying.
