Zorluk: OrtaAzure Virtual Machine Recovery and Restore

An administrator manages an Azure virtual machine named VM-App01 that is backed up to a Recovery Services vault. VM-App01 is configured with two network interface cards (NICs), and its primary network interface is associated with the backend pool of an internal Azure Load Balancer. Following a guest operating system corruption, the administrator needs to restore VM-App01 from a backup recovery point. The restored virtual machine must retain both network interfaces and its load balancer association. Which restore option should the administrator use?

  1. A
    Use the Replace Existing restore option to overwrite the active disks of the corrupted virtual machine.
  2. B
    Use the Create New restore option to automatically provision a new virtual machine with the original network interface settings and load balancer associations.
  3. Restore the virtual machine disks to a storage account, and then deploy a new virtual machine using the provided template while specifying the multiple network interfaces and load balancer configuration.Cevap
  4. D
    Download and run the Item-Level Recovery script to mount the backup disks as local drives on another virtual machine, and copy the network configuration metadata files to the original virtual machine.

Cevap

Restore the virtual machine disks to a storage account, and then deploy a new virtual machine using the provided template while specifying the multiple network interfaces and load balancer configuration.
Restoring the virtual machine's disks to a storage account (Restore Disks option) is necessary because the default Azure portal restore configurations (Create New and Replace Existing) do not support virtual machines with multiple network interfaces (NICs) or those associated with an Azure Load Balancer. Once the disks are restored as managed disks, you receive a deployment template that can be used or customized to recreate the virtual machine with its original network configurations and load balancer backend pool attachments.

Adım Adım Çözüm

1
Evaluate the restore requirements and limitations of the target virtual machine configuration.
Identify that the virtual machine uses multiple network interface cards (NICs) and is associated with an Azure Load Balancer, which are configurations unsupported by both 'Create New VM' and 'Replace Existing' portal restore paths.
Azure Backup limits the direct portal-based VM recreation and replacement options to simpler virtual machine architectures.
2
Select the 'Restore Disks' recovery option in the Azure portal and specify a target storage account.
Azure Backup restores the virtual machine's virtual hard disks (VHDs) as managed disks and generates a deployment template in the selected storage account.
Restoring disks allows the administrator to decouple disk recovery from virtual machine provisioning, enabling custom configurations.
3
Deploy the virtual machine using the generated template, configuring the multiple network interfaces and load balancer backend pool bindings.
The virtual machine is successfully recreated in its original architecture with all networking settings intact.
The custom deployment template or PowerShell deployment commands allow specifying the multi-NIC and load balancer properties that the basic portal wizard does not support.

Anahtar Kavram

Selecting the correct Azure VM restore method based on virtual machine configuration limits (multiple NICs, load balancers).
