Summary:
The documentation exclusively provides a PowerShell script using Windows-specific modules (e.g., MSOnlineBackup) and registry paths, with no mention of Linux or cross-platform alternatives. All instructions and next steps are tailored to Windows environments, and there are no examples or guidance for Linux users.
Recommendations:
- Add equivalent script samples for Linux environments, using bash or Python where possible.
- Document whether the MARS agent or similar backup functionality is available on Linux, and if so, provide Linux-specific instructions.
- If the feature is Windows-only, clearly state this limitation at the beginning of the documentation.
- Include a comparison table or section outlining differences in backup policy management between Windows and Linux platforms.
- Provide links to Linux backup policy documentation or third-party tools if native support is unavailable.
