You are designing a backup solution for a pool of Azure Virtual Machines hosting a business application. The solution must meet the following requirements:
- Retain daily backups for days.
- Retain weekly backups for years and store them in the most cost-effective storage tier available.
- Ensure backup data is resilient against a zone outage within the primary region.
Which two configurations should you include in the backup design?
- A Recovery Services vault configured with zone-redundant storage (ZRS) redundancyAnswer
- An Enhanced backup policy with a tiering rule to move weekly recovery points to the Vault-archive tierAnswer
- CA Recovery Services vault configured with locally redundant storage (LRS) redundancy
- DA Standard backup policy with instant restore retention set to 3 years
Answer
Configure a Recovery Services vault with zone-redundant storage (ZRS) redundancy and implement an Enhanced backup policy with a tiering rule to move weekly recovery points to the Vault-archive tier.
To satisfy the resiliency requirement against zone-level failures, the Recovery Services vault must use zone-redundant storage (ZRS). To store the weekly backups cost-effectively for 3 years, the solution must use an Enhanced backup policy that supports tiering the recovery points to the Vault-archive tier, which offers the lowest storage cost for long-term archival data.
