Nutanix Volumes is a block storage service that provides persistent storage for containerized applications running on Nutanix Kubernetes Engine (NKE). The NKE clusters are deployed with a Nutanix CSI driver that natively integrates with Volumes to enable backup and disaster recovery capabilities. Files is a file storage service that supports SMB and NFS protocols. Objects is an object storage service that supports S3-compatible APIs. Storage Container is a logical grouping of physical disks in a cluster.

According to Nutanix documentation on unified storage (NCP-US) v6, to automatically delete backups older than one year, an administrator should modify the existing bucket lifecycle policy to set the expiration period to one year. Lifecycle policies enable administrators to automate the transition of objects to different storage classes and to expire them altogether. In this scenario, modifying the existing bucket lifecycle policy to shorten the expiration period to one year will ensure that backups older than one year are automatically deleted to free up space in the cluster.

According to the Nutanix Unified Storage v6 documents at nutanix.com1, Objects supports Streaming Replication which allows you to replicate data between two or more Objects clusters for disaster recovery or data locality2. According to Splunk documentation3, SmartStore is an indexer capability that uses remote object stores such as Objects to store indexed data and reduce local storage requirements4. Therefore, by deploying another Objects instance at the remote site and replicating the SmartStore bucket from the primary site, you can improve read performance and reduce WAN latency for Splunk.

File Analytics is a tool used for monitoring and auditing file activity within an organization's file servers. The administrator needs to determine the most recent operation a user performed on the share cifs1 within the last 24 hours. To accomplish this task in File Analytics, the administrator should go to the Audit Trails section, where they can search for the cifs1 share and view the actions on the share over the past 24-hour range. This will allow the administrator to see all the activity that has occurred on the share, including the most recent operation performed by the user.
According to the Nutanix Unified Storage v6 documents at nutanix.com1, File Analytics captures all file activity for registered file server instances and provides an audit trail for administrators2. In the Audit Trails section, you can search for the user or the share name and view their operations over a specified time range2. This would allow you to determine the most recent operation a user performed on the share cifs1 within the last 24 hours.

Nutanix Files is a file storage service that supports SMB and NFS protocols. Access Based Enumeration (ABE) is a Windows feature that filters the list of available files and folders on the file server to include only those that the requesting user can access. Nutanix Files also supports replication to a DR site using Async DR.
