> We know that when we do backup for cassandra, we can do full bakcup with 
> snapshot, when we need to backup incremental data , incremental_backup can do 
> some help . 
> For snapshot we can just make snapshot for some keyspace/table. but 
> incremental backup will do all data backup(make hard link for all sstable 
> that flush from memtable or streaming ). we also know that commitlog's replay 
> can do some keyspace /table 's filter. 
> So  I think for incremental backup we also need some filter for it.After all 
> not all keyspace/table is so important to do backup.
