EUR not working in combination with DFS

It is not possible for users to restore (their own) files using EUR in situations where DFS (Distributed File System) is in place for the file servers.

Users receive the error message: "There are no previous versions available."

Previous versions of a file or of a folder in a DFS share are not listed if you access the share through a nested DFS link from a computer that is running Windows 7 or Windows Server 2008 R2.


A supported hotfix is available from Microsoft for the following Operating Systems.
  • Windows 7
  • Windows 7 Service Pack 1 (SP1)
  • Windows Server 2008 R2
  • Windows Server 2008 R2 Service Pack 1 (SP1)
The hotfix is available using this Support link:;EN-US;2466048

Our experience
The support article describes that this issue only occurs when you try to access the share by DFS name. <\\DFS\fileshare> When you access the share by the file server name it should work. <\\fileserver\fileshare>. However we experienced the issue also when accessing the share using the server name. Both issues where solved by the hotfix.

DPM 2010 does not calculate the size of BMR data source, but assumes 30 GB for all servers. Admins should change the value as per the size of BMR backups expected on their environments.
