Best Backup Types for Storage Quotas and Operating System Disks
Question
There is an Azure Stack Hub integrated system with 08 user subscriptions and each subscription having about 45 virtual machines (VMs)
You have been assigned the responsibility to plan a backup and restore strategy for this system.
Which type of backup would you use for storage quotas and operating system disks respectively?

A. B. C. D.Correct Answer: B
Infrastructure backup service helps in restoring the previously defined storage, compute and network quotas but it doesn't backup network configuration, IaaS Virtual machines and storage resources like storage accounts, tables, blobs,etc.
Option A is incorrect.
Infrastructural backup and Virtual machine backup should be used for storage quotas and operating system disks respectively.
Option B is correct.
Infrastructural backup and Virtual machine backup should be used for storage quotas and operating system disks respectively.
Option C is incorrect.
Virtual machine backup can not be used for both types of resources.
Option D is incorrect.
Infrastructural backup can not be used for both types of resources.

To plan a backup and restore strategy for an Azure Stack Hub integrated system with multiple subscriptions and virtual machines, it is important to understand the types of backup available in Azure Stack Hub.
Azure Stack Hub offers two types of backup for virtual machines and infrastructure:
- Virtual Machine backup: This type of backup is focused on backing up the virtual machines running in the Azure Stack Hub environment. This backup includes the data disks, operating system disks, and configuration files of the virtual machines.
- Infrastructural backup: This type of backup is focused on backing up the Azure Stack Hub infrastructure. It includes the data for the underlying storage, networking, and compute resources.
Based on the given scenario, with eight user subscriptions and 45 virtual machines per subscription, it is recommended to use Virtual Machine backup and Infrastructural backup respectively.
The reason behind this is that virtual machines have data disks and operating system disks that hold important data and configurations. Virtual Machine backup allows for quick and easy restoration of these disks in case of any disaster or system failure. In addition, the backup of the virtual machines can be scheduled and customized to fit the needs of each individual subscription.
On the other hand, Infrastructural backup is important for the underlying infrastructure that supports the virtual machines. This backup allows for quick restoration of the Azure Stack Hub environment in case of any disaster or system failure. It is important to note that the infrastructure backup should include all critical components such as storage, network, and compute.
Therefore, the correct answer to this question is A. Virtual Machine backup and Infrastructural backup respectively.
