I want to add a couple of questions regrading incremental backups: 1. If I already have a Cassandra cluster running, would changing the i ncremental_backups parameter in the cassandra.yaml of each node, and then restart it do the trick? 2. Assuming I am creating a daily snapshot, what is the gain from setting incremental backup to true?
