Hi Anishek they were created from more than a couple of months ago
You then probably free a fair amount of data :-). We didn't do any actions that would create a snapshot You shouldn't have any snapshot unless you drop or truncate a table, call them through "nodetool snapshot" or run repair without the -pr option. Also make sure to disable the 'snapshot_before_compaction' option, never see a case where this was useful or in use, I believe this one is here for debugging purposes (it is disabled by default). I believe that's all. i couldn't find the command in 2.0.17 Added in 2.1.0.beta-1: https://github.com/apache/cassandra/blob/trunk/CHANGES.txt#L1903 :-).
