Backup Exec 2012 Error:0xe0009425

Hi everyone just started using 2012 yesterday and got the below error on one server - any ideas??

Final error: 0xe0009425 - The Shadow Copy Components file system has been modified to contain only user-defined data, such as Backup Exec Deduplication Disk Storage (PDDE) and Distributed File System Replcation (DFSR). All other operating system-related data is now incorporated into System State. As a result, existing Shadow Copy Components file system backups and backup sets are incompatible with Backup Exec 2012. You should edit the job, delete the Shadow Copy Components selection, and then run the job again.

Does this mean remove the snapshot technology tick from the backup???

Thanks
