Zorluk: ZorAzure Virtual Machine Recovery and Restore

An administrator manages a Linux virtual machine named VM-Prod01 in the East US region. The virtual machine has two managed data disks and is encrypted using Azure Disk Encryption (ADE). VM-Prod01 is backed up to a Recovery Services vault that has Cross-Region Restore (CRR) enabled, with West US designated as the secondary region. Due to an extended outage in East US, the administrator needs to recover VM-Prod01 in West US as quickly as possible. Which recovery strategy should the administrator implement?

  1. Restore the disks of the virtual machine to the secondary region, and then use the template or PowerShell to create the virtual machine from the restored disks.Cevap
  2. B
    Restore the virtual machine by using the 'Create new' option directly in the secondary region from the Azure portal.
  3. C
    Restore the virtual machine by using the 'Replace existing' option and specifying the secondary region as the target.
  4. D
    Use Item-Level Recovery to download the recovery script, mount the disks in the secondary region, and promote the mounted volumes to a new virtual machine.

Cevap

Restore the disks of the virtual machine to the secondary region, and then use the template or PowerShell to create the virtual machine from the restored disks.
For virtual machines encrypted with Azure Disk Encryption (ADE), Azure Backup does not support creating a new virtual machine directly from the recovery point using the portal interface. Instead, the administrator must choose to restore the disks. Once the disks are restored to the target region, the administrator must use the generated Azure Resource Manager (ARM) template or PowerShell to recreate the virtual machine from those disks. This satisfies both the ADE recovery constraint and the Cross-Region Restore (CRR) capabilities.

Adım Adım Çözüm

1
Analyze the virtual machine characteristics and backup configuration to identify restore limitations.
The VM uses Azure Disk Encryption (ADE), and recovery must occur in the secondary region (West US) using Cross-Region Restore (CRR).
ADE-encrypted VMs do not support direct VM restoration via the portal, and CRR does not support the 'Replace existing' VM restore option.
2
Evaluate the permitted recovery methods for the given configuration.
The only supported workflow is to restore the virtual machine's disks to the secondary region.
Restoring disks is the mandatory first step for recovering ADE-encrypted VMs and is fully supported under CRR.
3
Recreate the virtual machine using the restored disks.
The administrator deploys the VM in West US using the templates generated during disk restore or via PowerShell.
This completes the recovery process while maintaining the original encryption parameters.
