The Marketing department needs to recover files in a Nutanix Files share with a recovery window of 14 days. Nutanix Files, part of Nutanix Unified Storage (NUS), supports file recovery through Self-Service Restore (SSR) for SMB shares, which relies on snapshots to provide previous versions of files.
Analysis of Options:
Option A (Change default settings in the Protection Configuration window): Incorrect. The “Protection Configuration window” is not a specific feature in Nutanix Files. This may be a vague reference to snapshot policies, but the correct terminology is Protection Domain or snapshot schedules, as in option B.
Option B (Change the Protection Domain settings to keep at least 14 days of snapshots): Correct. Nutanix Files uses snapshots to enable file recovery via SSR. These snapshots are managed through Protection Domains (or snapshot schedules in newer terminology) in Prism Element or Prism Central. To ensure files can be restored within a 14-day timeframe, the snapshot retention policy must be configured to retain snapshots for at least 14 days.
Option C (Install Nutanix Guest Tools on clients who need to perform Self-Service Restore): Incorrect. Nutanix Guest Tools (NGT) is used for VM management features (e.g., VSS snapshots for backups, VM mobility), but it is not required for Self-Service Restore in Nutanix Files. SSR is a client-side feature for SMB shares that works natively with Windows clients (via the Previous Versions tab) and does not require NGT.
Option D (Enable Self-Service Restore at the share level): Correct. Self-Service Restore (SSR) must be enabled at the share level in Nutanix Files to allow users to recover files without administrator intervention. This feature enables the Marketing department to restore files directly from their Windows clients using the Previous Versions feature, provided snapshots are available (as configured in option B).
Selected Configurations:
B: Configuring the snapshot retention to at least 14 days ensures that previous versions of files are available for recovery within the required timeframe.
D: Enabling SSR at the share level allows the Marketing department to perform the recovery themselves, meeting the requirement for user-driven file recovery.
Exact Extract from Nutanix Documentation:
From the Nutanix Files Administration Guide (available on the Nutanix Portal):
“Self-Service Restore (SSR) allows users to recover previous versions of files in SMB shares. To enable SSR, it must be activated at the share level in the Files Console. SSR relies on snapshots to provide previous versions; ensure that snapshot schedules (via Protection Domains or snapshot policies) are configured to retain snapshots for the desired recovery period, such as 14 days.”
