Summary
The documentation page demonstrates a strong Windows bias. All deployment and cleanup examples are provided exclusively in PowerShell, with no Azure CLI (bash) or Linux-native shell examples. The Bicep template provisions only Windows VMs, with no mention of Linux VM options or parameters. References to tools and workflows (such as 'right-click to paste' and PowerShell cmdlets) are Windows-centric, and there is no guidance for users on Linux or macOS platforms.
Recommendations
  • Add Azure CLI (bash) examples for deploying the Bicep template, including equivalent commands for parameter input and resource group deployment.
  • Provide a Linux VM option in the Bicep template, such as an additional parameter for selecting between Windows and Linux images, and document the allowed values.
  • Include cleanup instructions using Azure CLI commands, not just PowerShell.
  • Mention cross-platform compatibility of Azure Cloud Shell, and provide instructions for both bash and PowerShell environments.
  • Update references to input methods (e.g., pasting in Cloud Shell) to be platform-neutral.
  • Link to Linux-specific quickstarts or tutorials for VM backup with Bicep where available.

## 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:
