Hi,
The error code 0x809909F4 is an internal error code that indicates that the XML file may have errors or may not be well-formed.
To resolve this issue, you can check the ScriptingConfig.xml file in the \Microsoft Data Protection Manager\DPM\Scripting folder on the protected computer. Make sure that the XML file does not have any errors and that it is well-formed.
<?xml version="1.0" encoding="utf-8"?>
<ScriptConfiguration xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://schemas.microsoft.com/2003/dls/ScriptingConfig.xsd">
<DatasourceScriptConfig DataSourceName="Data source">
<PreBackupScript>"Path\Script Parameters" </PreBackupScript>
<PostBackupScript>"Path\Script Parameters" </PostBackupScript>
<TimeOut>30</TimeOut>
</DatasourceScriptConfig>
</ScriptConfiguration>
The following example for your reference:
I hope this helps!
