Duplicating data isn't a bad thing. Having a process that copies data into a reporting system solves the problem that otherwise it would be brittle (changes to either system might break things) and performance (any reporting queries affect realtime ones). Also, as it's decoupled, pulling in data from a 3rd system, e.g. CRM is possible.
