A company has several Azure virtual machines running critical line-of-business applications. They need a solution that provides automated backup of these VMs with a daily backup policy and ensures that they can restore any individual disk from a VM without having to restore the entire VM. Which Azure Backup feature should be utilized?
- AAzure VM Backup with Instant Restore
- BAzure VM Backup with Granular Disk Restore
- CAzure Backup for Files and Folders
- DAzure VM Backup with Disk Exclusion
Show answer & explanationAnswer & explanation
Correct answer: B. Azure VM Backup with Granular Disk Restore
Azure VM Backup allows for granular disk restore, meaning you can restore individual disks from a VM backup without needing to restore the entire virtual machine, which directly meets the requirement.
Why the other options are wrong
- A. Instant Restore capability allows for fast restoration of VMs using snapshots, but doesn't specifically highlight the ability to restore individual disks.
- C. Azure Backup for Files and Folders uses the MARS agent and is for specific files/folders on servers, not full VM disks.
- D. Disk Exclusion allows you to skip certain disks from backup, which is the opposite of ensuring all critical disks are backed up and individually restorable.
Azure VM Backup Granular Disk Restore
A capability of Azure Backup for virtual machines that allows users to restore individual disks or even specific files and folders from a VM backup, without needing to recover the entire virtual machine.
- Reduces recovery time and resource consumption compared to full VM restore.
- Provides flexibility for targeted data recovery.
- Supported for both Windows and Linux Azure VMs.
Memory trick: VM backup's disk restore, just a piece, not the whole floor.
