I am looking to remove unnecessary roles and features from Windows 2019 systems
and there is a new feature named System Data Archiver which is installed by default.
The official description says:
>
Provides services to collect and archive Windows Server system data.
Does anybody know a little more about this feature, especially what happens if this feature is uninstalled?
Qu'est-ce que the purpose of the System Data Archiver feature?

The **System Data Archiver** gathers data and provide them to the **System Insight** feature.
(Thanks to Yilia Zhao (MSFT CSG) who led me to the answer)
## Consequences of uninstalling the feature
If you uninstall the **System Data Archiver** feature the **System Insight** will log the following type of errors:
```
ProviderName : Microsoft-Windows-System-Insights
Id : 147
Message : Unable to load DLLs required to gather data for capability 'CPU capacity forecasting'. Potential issues: Feature 'System-DataArchiver' is uninstalled. if so, install the 'System-DataArchiver' feature.
```
Furthermore, when you uninstall the **System Data Archiver** feature it removes the collected data too. You must then wait at least 6 days after reinstalling it before **System Insight** can make a forecast.
