Can't see sharepoint Site in DPM protection.

Hello,I like to add sharepoint site to be protected by DPM R2 2012, so I done all steps:

1. Install agent

2. On SharepointServer FE

C:\Program Files\Microsoft Data Protection Manager\DPM\bin>ConfigureSharepoint.exe -enablesharepointprotection - VSS Service get in running space

STADM.EXE -o -registerwsswriter

To check it I run command:

vssadmin list writers

Result

Writer name: 'SharePoint Services Writer'
   Writer Id: {da452614-4858-5e53-a512-38aab25c61ad}
   Writer Instance Id: {838ca299-176e-427f-abb2-710e9e959c55}
   State: [1] Stable
   Last error: No error

But when I'm trying to create prtection group on DPM I dont see sharepoint site, some have any idea ?
