An administrator decides to restore VMware vCenter from a file-based backup following a failed upgrade. Which interface should the administrator use…

The restore process for a vCenter Server from a file-based backup is initiated using the vCenter GUI Installer, which is run from the vCenter Server ISO file. This method is specifically designed for disaster recovery scenarios, such as a failed upgrade, where the existing vCenter Server is no longer operational. The installer provides a "Restore" workflow that first deploys a new vCenter Server appliance and then populates it with the configuration and data from the selected backup file.

A. The Direct Console User Interface (DCUI) is a low-level interface for basic network configuration and troubleshooting of the appliance; it lacks restore functionality.

B. The vCenter Management Interface (VAMI) is used to configure backups and manage the running appliance, but it cannot be used to perform a restore when the vCenter is non-functional.

C. The vSphere Client is the management interface for the vSphere environment. It is dependent on a functional vCenter Server and would be inaccessible in a failure scenario.

1. VMware vSphere 7.0 Documentation

"vCenter Server Installation and Setup" Guide.

Section: "Restore a vCenter Server from a File-Based Backup"

Content: The guide explicitly states

"You can restore a vCenter Server instance from a file-based backup by using the GUI installer of the vCenter Server appliance." It then details the procedure

which begins with running the installer from the ISO and selecting the "Restore" option.

2. VMware vSphere 8.0 Documentation

"vCenter Server Installation and Setup" Guide.

Section: "Restore vCenter from a File-Based Backup"

Content: This document confirms the procedure for a newer version: "To restore a vCenter instance from a file-based backup

you must deploy a new vCenter appliance by using the GUI installer... In the vCenter installer

click Restore." This reinforces that the GUI installer is the correct tool.
