Summary
The documentation provides both Azure CLI and PowerShell examples for configuring selective disk backup and restore, but the PowerShell examples are inherently Windows-centric. There is a notable emphasis on Windows tools and patterns, such as referencing BitLocker for encryption and using PowerShell as a primary scripting interface. Linux-specific instructions are limited to brief notes (e.g., ensuring 'lsblk' and 'lsscsi' are available), and there are no Linux shell (bash) script examples or explicit Linux command-line walkthroughs. Windows terminology and tools (e.g., drive C:, BitLocker) are mentioned before or more prominently than their Linux equivalents.
Recommendations
  • Add explicit Linux (bash) command-line examples for common operations, such as using Azure CLI from a Linux shell.
  • Include Linux-specific scripting examples (e.g., bash scripts) alongside PowerShell examples.
  • When discussing encryption, mention Linux (dm-crypt) and Windows (BitLocker) equivalently and in parallel.
  • Ensure that Linux prerequisites and troubleshooting steps are as detailed as those for Windows (e.g., provide sample commands to install 'lsblk' and 'lsscsi' on various distributions).
  • Where possible, use neutral language (e.g., 'command line' instead of 'PowerShell') and avoid assuming Windows as the default environment.
  • Add screenshots or walkthroughs of the Azure portal experience for both Windows and Linux VMs, highlighting any differences.
