Dave Brosius commented on CASSANDRA-7311:
-----------------------------------------

I think it would be better if this option was stored in the schema_keyspaces 
table so that the setting doesn't have to be replicated across the entire 
cluster's yamls. 

In that case i would think you would add an option to the create keyspace 
command such as

create keyspace foo with replication = {'class' : 'SimpleStrategy', 
'replication_factor': 1} and incremental_backup=true;

if the keyspace didn't have a value set, the system wide setting would be used, 
or perhaps if not specified the default would be written into the 
schema_keyspaces table.

> Currently incremental backups are globally defined, however this is not 
> always appropriate or required for all keyspaces in a cluster. 
> As this is quite expensive, it would be preferred to either specify the 
> keyspaces that need this (or exclude the ones that don't).
