Question

Difficulty: MediumAzure Virtual Machine Backup Configuration

A company runs a production workload on a virtual machine named vm-db-prod in the Central US region. You are tasked with configuring a backup solution for vm-db-prod using Azure Backup. The backup solution must satisfy the following requirements:
- Create backups multiple times per day to minimize potential data loss.
- Enable the ability to restore the virtual machine in the East US secondary paired region in the event of a regional disaster.
Which configuration should you implement to meet these requirements?

  1. A
    Create a Recovery Services Vault in the Central US region configured with Geo-redundant storage (GRS) and Cross Region Restore enabled, and associate it with a Standard backup policy
  2. B
    Create a Recovery Services Vault in the East US region configured with Locally-redundant storage (LRS), and associate it with an Enhanced backup policy
  3. Create a Recovery Services Vault in the Central US region configured with Geo-redundant storage (GRS) and Cross Region Restore enabled, and associate it with an Enhanced backup policyAnswer
  4. D
    Create a Recovery Services Vault in the Central US region configured with Zone-redundant storage (ZRS) and Cross Region Restore enabled, and associate it with an Enhanced backup policy

Answer

Create a Recovery Services Vault in the Central US region configured with Geo-redundant storage (GRS) and Cross Region Restore enabled, and associate it with an Enhanced backup policy.
The correct configuration requires the Recovery Services Vault to be in the same region as the virtual machine (Central US). To perform backups multiple times per day, an Enhanced backup policy must be used since Standard backup policies only support a single daily backup. To allow the virtual machine to be restored in the secondary paired region (East US), the vault's storage redundancy must be configured as Geo-redundant storage (GRS) and Cross Region Restore must be explicitly enabled.

Step-by-Step Solution

1
Determine the required vault region
The Recovery Services Vault must be created in the Central US region.
Azure Backup requires that the Recovery Services Vault resides in the same geographical region as the source virtual machine being backed up.
2
Select the appropriate backup policy type
Select the Enhanced backup policy type.
The Standard backup policy type only supports one backup per day. The Enhanced backup policy type must be used to schedule multiple backups per day (such as hourly backups).
3
Configure vault storage redundancy and restore options
Configure the vault with Geo-redundant storage (GRS) and enable Cross Region Restore (CRR).
Cross Region Restore allows restoration of backups in the secondary paired region (East US). Enabling Cross Region Restore requires that the vault storage redundancy is set to Geo-redundant storage (GRS) before backups are configured.

Key Concept

Azure Virtual Machine Backup configuration requirements, specifically regional alignment, standard vs. enhanced policies for backup frequency, and storage redundancy settings required for Cross Region Restore.
