A small business needs a cost-effective backup solution for its Azure Virtual Machines. The VMs host non-critical development environments, and a daily backup is sufficient. The Recovery Point Objective (RPO) can be up to 24 hours. Which Azure service is most appropriate for this scenario?
- AAzure Backup
- BAzure Site Recovery
- CAzure Disk Snapshots
- DAzure Storage Account (manual VHD copy)
Show answer & explanationAnswer & explanation
Correct answer: A. Azure Backup
Azure Backup provides cost-effective, centralized backup for Azure VMs, supporting daily backups and meeting a 24-hour RPO, which is suitable for non-critical development environments.
Why the other options are wrong
- B. Azure Site Recovery is a disaster recovery solution, designed for continuous replication and rapid failover, which is overkill and more expensive for non-critical daily backups with a 24-hour RPO.
- C. Azure Disk Snapshots are point-in-time copies of disks. While they can be part of a backup strategy, they don't provide a complete, automated, and policy-driven backup solution for an entire VM with recovery management like Azure Backup.
- D. Manually copying VHDs to an Azure Storage Account would be labor-intensive, error-prone, and not a scalable or automated backup solution for VMs.
Azure Backup for VMs
Azure Backup provides a managed, scalable, and cost-effective solution for backing up Azure Virtual Machines.
- Policy-based backups (e.g., daily, weekly).
- Supports various retention policies.
- Cost-effective for less stringent RTO/RPO requirements.
Memory trick: Azure Backup, simple and cheap for VMs.
