Zorluk: OrtaAzure Virtual Machine Recovery and Restore

An administrator is responsible for recovering a critical virtual machine named `vm-db-accelerate` that runs Windows Server 2025. The virtual machine has a premium OS disk and a premium data disk with Write Accelerator enabled. The virtual machine is backed up daily to a Recovery Services vault. Following a database corruption event, the administrator needs to restore the virtual machine from a backup while ensuring that Write Accelerator remains enabled on the restored data disk. Which restore option must the administrator use?

  1. Restore the disks, and then create a new virtual machine from the restored disks.Cevap
  2. B
    Select the Create New restore option from the Azure Portal restore wizard.
  3. C
    Select the Replace Existing restore option to overwrite the disks of the running virtual machine.
  4. D
    Use Item-Level Recovery to download the virtual hard disk files and attach them to a new virtual machine.

Cevap

Restore the disks, and then create a new virtual machine from the restored disks.
Restoring the disks and then creating a new virtual machine is the correct approach. According to Microsoft Azure Backup documentation, if a virtual machine has Write Accelerator enabled, performing a direct 'Create New' virtual machine restore will result in a restored virtual machine without Write Accelerator configured. To preserve this configuration, you must choose 'Restore Disks' and then create the virtual machine from those restored disks.

Adım Adım Çözüm

1
Navigate to the Recovery Services vault, select the backup item for the virtual machine, and trigger a restore operation.
The restore configuration options are displayed.
To initiate the recovery process from an existing backup point.
2
Choose the 'Restore disks' option instead of 'Create new' or 'Replace existing', specify a staging storage account, and start the restore.
The virtual hard disks (VHDs) and deployment templates are restored to the staging storage account.
Azure Backup does not support enabling Write Accelerator on restored VMs when using the direct 'Create New' VM restore option. Restoring disks is required to maintain this custom configuration.
3
Use the generated ARM template or custom PowerShell/CLI commands to deploy a new virtual machine from the restored disks, ensuring Write Accelerator is configured.
A new virtual machine is created with the Write Accelerator configuration intact on the premium data disk.
To complete the VM restoration while preserving advanced disk configurations.
