Hosted feature layers greater than 2 GB in size fail to export as a file geodatabase in Portal for ArcGIS.

Workaround

1. Open ArcGIS Pro and connect to the Portal environment.
2. Click 'Add Data' in ArcGIS Pro, connect to the Portal for ArcGIS content, and add the feature layer to export.
3. Right-click the layer, go to Data, and click Export Features.
4. In the Environments tab, ensure 'Maintain Attachments' is selected (if applicable).
5. Click Run to create a new feature layer and new feature class in the specified output location.

Alternatively, create a file geodatabase replica from the REST page of the feature service and run the process asynchronously.
