    We have installed Acronis True Enterprise with Universal Restore
    Plugin on a Windows 2003 R2 Server. Unfortunately we are not able
    to create a backup (whole partition), because the software is
    not able to "lock" the partition. The error message is
    "Unable to create volume snapshot (0x70021)".

    Perhaps this has to do with the Distributed File System (DFS)
    which is running on the system. Please keep in mind that this
    DFS is a integrated part of the Microsoft operating system (R2).

    Does anybody have experience of Acronis with MS DFS?

    Build : Acronis True Image Enterprise Server® with
    Acronis Universal Restore® version 9.1 (build 3,71:cool:
    System: Windows Server 2003 R2 (!)
    Acronis TT: #797035

    Special software:
    MS DFS (Distributed File System; R2 Feature)
