Recover purged data on windows server 2012 file system with active deduplication

 Hello,

I have a very difficult situation, i was using robocopy command to move data between two virtual disk in a windows 2012 file server, but i miss used the command  and it purged most of the information of our public relations department

These information was in a disk with active windows 2012 deduplication, i try to recover it from our system center DPM backups but i understand later that the backup was not valid because the DPM version we used at the time do no recognize the new deduplication feature, so all the data files now are corrupted

I also try to use the Getdataback software to recover deleted files but the most i found was the chunkdata from deduplication

Now i need to understand what chances we wave to recover some or all of this data using the DPM backups we have available or reconstructing the deduplication using the chunk data

Best Regards
