Re: [Marketing Mail] Re: [Marketing Mail] Cassandra 2.1: Snapshot data changing while transferring

Hi Paul, If I understand correctly, you are making a tar file with all the folders named "snapshots" (i.e. the folder under which all the snapshots are created. So you have one /snapshots /folder per table). If this is the case, when you are executing "nodetool repair", Cassandra will create a
