On-demand Backup of Azure VMs
Go to your Azure Backup account, click on Settings, and in the PROTECTED ITEMS section, select Backup Items
Select your VM, the screen will also show last Backup Status, and then select Backup now to start Backup of your Virtual Machine immediately.
The on-demand backup also requires you to select the retention period of your VM. The backup will automatically be deleted once the period expires.
Restoration of Virtual Machine
On the same screen, where we selected Backup now, also shows Restore VM option. Once you select Restore VM option, you will need to select from multiple restore points giving you option to select the best desired state of VM to restore to.
You will be prompted to restore the Virtual Machine to new VM.
Azure Backup is definitely a great option for enterprises to backup On-premise and Azure workloads. However, a greater support for Linux such as file system restore would have added great use case in the live environments. In the next articles, we will see Backup Architecture leveraging StorSimple and how to backup On-premise workloads.
