We are running into problems where Backup jobs are taking away a huge bandwidth out of the C* nodes. While we can schedule a particular timing window for backups alone, the request pattern is so random; there is no particular time where we can schedule backups, periodically.
My current thinking is to run backups against a replica that does not serve requests. Questions: 1. *Is it the right strategy? * 2. *if it is - how do I pull a replica out from serving requests ? * 3. *If not, what is the right backup strategy ?*
