Zorluk: OrtaDesign Azure Backup Solutions

You are designing a backup solution for Azure Virtual Machines that host a financial application. The solution must meet the following requirements:
- Backups must be performed twice daily to meet a strict recovery point objective (RPO).
- File-level recoveries from the last 77 days must be performed instantly using local snapshots to minimize the recovery time objective (RTO).
- All vault backups must be available for restore in a paired secondary Azure region in the event of a primary region disaster.
- Vaulted backups must be retained for 33 years.

Which two configurations should you include in the design?

  1. Configure an Enhanced backup policy with the snapshot retention set to 77 days.Cevap
  2. Configure a Recovery Services Vault with geo-redundant storage (GRS) and enable Cross Region Restore (CRR).Cevap
  3. C
    Configure a Standard backup policy with the snapshot retention set to 77 days.
  4. D
    Configure a Recovery Services Vault with locally redundant storage (LRS) to minimize backup costs.

Cevap

Configure an Enhanced backup policy with the snapshot retention set to 77 days, and configure a Recovery Services Vault with geo-redundant storage (GRS) and enable Cross Region Restore (CRR).
To meet the requirements of a twice-daily backup frequency and 77 days of instant recovery snapshot retention, an Enhanced backup policy must be configured. Standard policies do not support multiple backups per day and are limited to a maximum of 55 days of snapshot retention. To ensure the backups are restorable in the paired secondary region during a primary region disaster, the Recovery Services Vault must use geo-redundant storage (GRS) with Cross Region Restore (CRR) enabled.

Adım Adım Çözüm

1
Analyze backup frequency and instant recovery snapshot retention needs.
Determined that the solution requires a twice-daily backup schedule and a snapshot retention of 77 days.
Standard VM backup policies only support daily backups and a snapshot retention range of 11 to 55 days. Supporting a twice-daily frequency and a 77-day snapshot retention requires the Enhanced backup policy.
2
Evaluate disaster recovery requirements for the vault backups.
Determined that vault backups must survive a primary region disaster and be restorable in the secondary region.
Locally redundant storage (LRS) does not protect against regional outages. To allow restores in a secondary paired region when the primary region is unavailable, the Recovery Services Vault must be configured with geo-redundant storage (GRS) and Cross Region Restore (CRR) enabled.
3
Select the correct combination of policy and vault settings.
Identified the need for an Enhanced backup policy and a GRS-configured Recovery Services Vault with CRR enabled.
Selecting these configurations satisfies all the design constraints including the RPO, instant RTO recovery window, and regional disaster resilience.

Anahtar Kavram

Selecting between Standard and Enhanced backup policies based on frequency and snapshot retention requirements, and choosing appropriate vault storage redundancy for secondary region recovery.
