Pre/Post backup script online backup on VM level \Online\Servername - what is the format of datasource?

Question

Hello, I am trying to set prebackup script for DPM 2012 R2 UR2 on Windows 2003 R2 VM with SQL server 2005 Inside.
I would like to disable SQLVssWriter during the VM backups  (in DPM backup of \Online\Servername).
What is the correct format of ScriptingConfig.xml? This is what I have tried but it did not work.
<?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="System Protection ">
     <PreBackupScript>"C:\Sources\DPMscripts\PreBackup.cmd" </PreBackupScript>
     <PostBackupScript>"C:\Sources\DPMscripts\PostBackup.cmd" </PostBackupScript>
     <TimeOut>90</TimeOut>
   </DatasourceScriptConfig>
</ScriptConfiguration>
Can you point me to a right direct?

ok, let's try:
modified a query like this:
Use dpmdb
select ComponentName,caption from tbl_RM_RecoverableObject
where Caption like cast('%Online%' as ntext)
order by cast(Caption as nvarchar)
and I get the table like this:
E473B7C4-B1EC-49DC-A54C-6A65D36C64B3  Online\LCBUILD2
Now trying the script:
<?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="E473B7C4-B1EC-49DC-A54C-6A65D36C64B3">
      <PreBackupScript>"C:\Sources\DPMscripts\PreBackup.cmd" </PreBackupScript>
      <PostBackupScript>"C:\Sources\DPMscripts\PostBackup.cmd" </PostBackupScript>
      <TimeOut>90</TimeOut>
    </DatasourceScriptConfig>
 </ScriptConfiguration>
I'll let you know if it works...
