A CIO has been reviewing the corporate BCDR plan.

Smart DR enables granular recovery of individual file shares in Nutanix Files by replicating data at the share level. This allows for more fine-grained control over the failover process and ensures that only critical data is recovered in the event of a disaster or outage.

 Files Smart DR is a feature that allows you to replicate between Files instances, either on-premises or running on Nutanix Cloud Clusters on AWS1. With Files Smart DR, you can configure granular share replication, which means you can select which shares to replicate and which ones to exclude1. Therefore, the correct answer to your question is B. Smart DR.

Files Smart DR also supports replicating snapshots between the source share and its target, which can help with data recovery and compliance2. Additionally, Files Smart DR is the mechanism by which Files will support disaster recovery in the Nutanix Xi cloud3.
