Difficulty: Very hardDesign Azure Backup Solutions

You are designing an Azure Backup solution for a suite of critical Azure Virtual Machines hosting a high-performance SAP HANA database. The solution must satisfy the following requirements:
- Back up the virtual machines 22 times per day to protect against database transaction losses.
- Retain the local instant recovery snapshots on the virtual machines' managed disks for 1414 days to allow quick operational restores.
- Protect the backup data against regional disasters by replicating it to a secondary paired region, allowing recovery even if the primary region is completely unavailable.

Which of the following configuration options must you include in your backup design? (Select TWO)

  1. Configure a Recovery Services Vault with Geo-Redundant Storage (GRS) and enable Cross-Region Restore (CRR).Answer
  2. Create an Enhanced backup policy with a twice-daily backup schedule and set the instant restore retention to 1414 days.Answer
  3. C
    Create a Standard backup policy with a twice-daily backup schedule and set the instant restore retention to 1414 days.
  4. D
    Configure a Recovery Services Vault with Locally Redundant Storage (LRS) and enable Cross-Region Restore (CRR).

Answer

To meet the requirements, the design must use a Recovery Services Vault configured with Geo-Redundant Storage (GRS) and Cross-Region Restore (CRR) enabled, combined with an Enhanced backup policy scheduled for twice-daily backups and 1414 days of instant restore retention.
The correct strategy requires configuring a Recovery Services Vault with Geo-Redundant Storage (GRS) and enabling Cross-Region Restore (CRR) to satisfy regional resilience and failover capabilities. Additionally, an Enhanced backup policy must be configured because a Standard policy cannot support the required twice-daily backup schedule or the 1414 days of instant restore snapshot retention.

Step-by-Step Solution

1
Evaluate the backup frequency and operational recovery requirements.
The requirements dictate twice-daily backups and local snapshot retention of 1414 days.
This determines whether a Standard or Enhanced backup policy is needed based on policy limits.
2
Select the appropriate backup policy type.
Select an Enhanced backup policy.
Standard backup policies support only one backup per day and limit instant recovery retention to between 11 and 55 days, whereas Enhanced policies support multiple daily backups and up to 3030 days of instant recovery retention.
3
Determine the vault storage redundancy and restore features.
Configure a Recovery Services Vault with Geo-Redundant Storage (GRS) and enable Cross-Region Restore (CRR).
GRS ensures replication to the paired region, and CRR allows immediate restore operations in the secondary region if the primary region goes offline.
