Hi,
To see if this is a Windows backup issue, or a DPM replica (storage) issue, try the following
1) Set up a network share on a remote machine
\\server\bmrshare
2) From an administrative command prompt on the PS, type:
wbadmin.exe start backup -allcritical -backuptarget:\\server\bmrshare
3) If that fails with the same error, off to windows support you go, else, see if your DPM storage pool disk has greater than 512 byte sectors (IE 4K sectors) - if so that is the problem because Windows server 2008 R2 backup cannot make .vhd files on drives
with sectors >512 bytes.
You can Identify if the DPM storage pool disk is a 4k drive by doing the following:
MSInfo32 will identify the 4k native drive in Components/Storage/Disks with a
Bytes/Sector = 4096
