The direct‐to‐host emergency restore operation lets you restore the VM that contains vCenter Server, vCenter Server Appliance, or Platform Services Controller when vCenter Server becomes unavailable or when you cannot access the vSphere Data Protection user interface by using the vSphere Web Client.
vSphere Data Protection depends on vCenter Server for many of the vSphere Data Protection core operations. When vCenter Server becomes unavailable, an emergency restore operation can restore the VM that contains the vCenter Server, vCenter Server Appliance, or Platform Services Controller directly on the ESXi host that is running the vSphere Data Protection Appliance. The Emergency Restore tab displays a list of VMs that have been backed up by the vSphere Data Protection Appliance. These VMs that contain vCenter Server or Platform Services Controller instances can be restored as new VMs on the ESXi host where the vSphere Data Protection Appliance is running. For best practices, recommendations, and limitations of the emergency restore operation, see the vSphere Data Protection documentation.
- Log in as an administrator to the vSphere Client, click the Summary tab.
- Under Host Management, select Disassociate Host from vCenter Server.
- Click Yes when prompted to disassociate the host from vCenter Server.
- In a Web browser, navigate to the vSphere Data Protection Configure Utility.
- On the Emergency Restore tab, select the VM that will serve as the restore point, and click Restore.
- In the Host Credentials dialog box, enter valid host credentials and click OK.
- In the Restore a Backup dialog box, enter a new name.
- Select a datastore as the destination target for the backup, and click Restore.
Caution: The datastore capacity size is listed. Make sure you select a datastore with enough disk space to accommodate the restore. Insufficient space causes the restore to fail.
- In the Recent Tasks pane, check the progress to verify that the restore is submitted successfully.
Note: The restored VM is listed in the inventory at the vSphere host level. Restoring to a more specific inventory path is not supported.
