Summary
The documentation page demonstrates a strong Windows bias. All deployment and cleanup examples use Azure PowerShell scripts, with no mention or example of Azure CLI or Bash equivalents. The Bicep template provisions only Windows VMs, and the allowed OS versions are exclusively Windows. The instructions and references (such as monitoring and starting backup jobs) link to PowerShell-specific guides. There is no guidance for Linux users or for deploying/protecting Linux VMs.
Recommendations
  • Provide parallel Azure CLI/Bash examples for deploying the Bicep template, starting backup jobs, monitoring, and cleanup.
  • Include or reference a Bicep template that provisions a Linux VM, or show how to modify the template for Linux.
  • Mention both Windows and Linux options in the prerequisites and throughout the guide, including links to relevant Linux documentation.
  • When referencing tools or scripts, present cross-platform options (e.g., Azure CLI before or alongside PowerShell).
  • Ensure that links to further reading or next steps include Linux-focused guides as well as Windows ones.

## Validate the deployment

### Start a backup job

The template creates a VM and enables backup on the VM. After you deploy the template, you need to start a backup job. For more information, see [Start a backup job](quick-backup-vm-powershell.md#start-a-backup-job).

### Monitor the backup job

To monitor the backup job, see [Monitor the backup job](quick-backup-vm-powershell.md#monitor-the-backup-job).

## Clean up resources

- If you no longer need to back up the VM, you can clean it up.
- To try out restoring the VM, skip the clean-up process.
- If you've used an existing VM, you can skip the final [Remove-AzResourceGroup](/powershell/module/az.resources/remove-azresourcegroup) cmdlet to keep the resource group and VM.

Follow these steps:

1. Disable protection, remove the restore points and vault.

1. Delete the resource group and associated VM resources, as follows:
