Zorluk: OrtaDesign Azure Backup Solutions

An enterprise uses Azure Files shares to store business-critical documents. You are designing a backup solution using Azure Backup that satisfies the following requirements:
- Shared file data must be backed up three times per day to achieve an 88-hour Recovery Point Objective (RPO).
- Backup data must be retained for 1010 years to comply with regulatory requirements.
- The vault storage must remain resilient to zone outages within the primary region while minimizing storage costs.

Which two of the following configuration options should you select to meet these requirements? (Select two.)

  1. An Enhanced backup policyCevap
  2. A Recovery Services vault configured with Zone-Redundant Storage (ZRS)Cevap
  3. C
    A Standard backup policy
  4. D
    A Recovery Services vault configured with Locally Redundant Storage (LRS)
  5. E
    A Recovery Services vault configured with Read-Access Geo-Redundant Storage (RA-GRS) to allow write operations in the secondary region before a failover is initiated

Cevap

The correct configuration requires choosing an Enhanced backup policy and a Recovery Services vault configured with Zone-Redundant Storage (ZRS).
The combination of an Enhanced backup policy and a Recovery Services vault configured with Zone-Redundant Storage (ZRS) meets all the requirements. The Enhanced policy is required for Azure Files to support sub-daily backups (meeting the 8-hour RPO) and long-term storage in the vault tier (meeting the 10-year retention rule). The ZRS configuration ensures the backup data is resilient to zone outages while being more cost-effective than geo-redundant storage.

Adım Adım Çözüm

1
Analyze the RPO and retention requirements to determine the required backup policy tier.
An 8-hour RPO requires multiple backups per day, and a 10-year retention rule requires vault-level storage rather than just share snapshots. This necessitates an Enhanced backup policy, as Standard policies only support daily backups and a maximum of 200 days of snapshot retention.
Determines the backup policy tier required to meet the operational and compliance SLA.
2
Evaluate the resiliency and cost-minimization requirements for backup storage redundancy.
To survive a zone outage within the primary region, Zone-Redundant Storage (ZRS) must be used. Locally Redundant Storage (LRS) is not zone-resilient, and Geo-Redundant Storage (GRS) violates the cost-minimization requirement by replicating data across regions.
Identifies the correct storage replication tier for the Recovery Services vault.
3
Select the two correct configuration options based on the policy and vault redundancy requirements.
Select the Enhanced backup policy and the ZRS-configured Recovery Services vault.
Combines the policy and storage tier findings into the final configuration.

Anahtar Kavram

Azure Backup supports Standard and Enhanced backup policies, with the Enhanced policy enabling sub-daily backups and vault-tier storage for long-term retention. Storage redundancy options like ZRS protect vault data from zone failures cost-effectively.
