A dental group runs Windows and Linux VMs in Azure. It needs backups that capture a consistent state of the databases inside those VMs, allow restoring individual files without rebuilding a machine, and keep recovery points available in a paired region. Which service should you configure?
Show answer and explanation
Answer: B
Azure Backup stores recovery points in a Recovery Services vault. It takes application-consistent snapshots using VSS on Windows or pre and post scripts on Linux, allows file-level restore from a recovery point, and with cross-region restore enabled lets you restore in the paired region. Plain disk snapshots are usually crash-consistent unless coordinated. Site Recovery is built for failover rather than long backup history, and geo-replication of storage does not create application-consistent restore points.
Why the other options are wrong
- A. Scheduled snapshots are usually crash-consistent. They lack the application quiescing that Azure Backup performs, and restoring single files from them is clumsy.
- C. Site Recovery is designed to fail workloads over to another region quickly. It does not keep a long history of backup points for file-level restore.
- D. Geo-replication copies storage objects to another region for durability. It does not create application-consistent restore points for VM workloads.
