What is the DR approach of Splunk ES on AWS?

Hi everyone, Assume the best practices of Splunk AWS is deployed on production AWS region (e.g. London). How to design the DR of Splunk? 1. create another best practice design in another region (e.g. Paris) and extend the SH cluster and indexer cluster to the Paris region? 2. what if a hot-stanby is no required, is it able to take a whole of the Splunk (including VPC, AZ, subnets, Security groups, instances, EBS) and archive it in S3 bucket and restore it in Paris region manually? Best Practice Architecture: https://aws.amazon.com/quickstart/architecture/splunk-enterprise/ Thanks.
