Nutanix documentation for Prism Central point-in-time backup states that Prism Central supports up to 30 days of restore points for recovery. This is documented consistently across Nutanix guidance for backup to Nutanix Objects, AWS S3, and generic S3-compliant storage. Because the platform wording is explicit and repeated, the correct answer is 30 days. ( portal.nutanix.com , portal.nutanix.com , portal.nutanix.com ) This is a retention-boundary question, so it is best answered directly from the official limit rather than from memory. The values 7, 14, and 90 days are exam-style distractors, but Nutanix's supported restore-point duration for Prism Central recovery is 30 days. In practical terms, that means administrators should plan their backup retention and operational expectations around that documented maximum rather than assuming indefinite or quarterly restore history.
