A company is using Azure Backup to protect their critical Azure virtual machines. They discover that a VM's operating system disk needs to be restored to a previous state, but they want to keep the existing data disks and configuration. Which restore option should they choose to achieve this specific outcome?
- ARestore to New VM
- BRestore VM
- CRestore Disks
- DFile Recovery
Show answer & explanationAnswer & explanation
Correct answer: C. Restore Disks
The 'Restore Disks' option in Azure Backup allows you to restore individual disks (OS or data) from a recovery point. This enables you to replace just the OS disk while retaining the existing data disks and VM configuration, which is exactly what the scenario requires.
Why the other options are wrong
- A. Restore to New VM creates an entirely new VM with all disks from the backup, which is not suitable for keeping existing data disks on the original VM.
- B. Restore VM creates a new VM with all disks from the recovery point, potentially overwriting existing data disks or requiring a new VM.
- D. File Recovery is for restoring individual files or folders, not entire disks or VMs.
Azure Backup Disk Restore
Azure Backup's disk restore option allows restoring individual disks (OS or data) from a VM backup to either create a new VM or replace an existing disk.
- Provides granular control over disk restoration.
- Useful for OS disk corruption while preserving data disks.
- Can be used to create a new VM from restored disks or replace a disk on an existing VM.
Memory trick: VM for whole, Disks for parts, Files for tiny starts.
