To protect a Nutanix Files instance between two sites with a1-hour RPO (Recovery Point Objective),four recovery points, andcross-hypervisor capabilities, the administrator should useSmart DR. Smart DR is a disaster recovery feature for Nutanix Files that enables replication of file shares between primary and recovery sites, supporting automated failover and recovery with configurable RPOs and retention policies.

TheNutanix Unified Storage Administration (NUSA)course explains that “Smart DR for Nutanix Files supports replication between sites with configurable RPOs as low as 1 hour, multiple recovery points, and cross-hypervisor compatibility, ensuring seamless failover and recovery.” Smart DR allows the administrator to set a replication schedule to meet the 1-hour RPO requirement, retain four recovery points by configuring the retention policy, and supports cross-hypervisor environments (e.g., AHV, ESXi, Hyper-V) since Nutanix Files operates at the file-share level, independent of the underlying hypervisor.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “Smart DR provides disaster recovery for Nutanix Files with an RPO as low as 1 hour, the ability to retain multiple recovery points (e.g., four snapshots), and compatibility across hypervisors, making it ideal for multi-site file server protection.” The feature uses asynchronous replication to copy file share data to the recovery site, ensuring data consistency and availability.

The other options are incorrect:

Protection Policies: Protection Policies in Nutanix are used for backup and snapshot schedules, typically for VMs or volumes, but they are not specific to Nutanix Files and do not support cross-site replication with the specified RPO.

Smart Sync: Smart Sync is not a Nutanix feature; it may refer to third-party tools or unrelated functionalities and is not applicable here.

Protection Domain: Protection Domains are used for VM-level replication and disaster recovery in Nutanix, not for Nutanix Files, and they are hypervisor-specific, which may limit cross-hypervisor support.

The NUSA course documentation highlights that “Smart DR meets stringent RPO requirements, such as 1-hour intervals, and supports multiple recovery points while ensuring compatibility across hypervisors, making it the optimal solution for Nutanix Files disaster recovery.”
