DPM 2012 can’t backup server with Sophos Installed

While setting up our new backup server (System Centre Data Protection Manager 2012) one of the issues we came across was with it failing the data synchronizations with a error message like this one-

Type:     Synchronization
Status:  Failed
Description:        Changes for Volume C:\ on <servername><domainname> cannot be applied to \\?\Volume{4fac41a1-0f58-11dc-8993-806d6172696f}\ProgramData\Sophos\AutoUpdate\Cache\savxp\. (ID 112 Details: Cannot create a file when that file already exists (0x800700B7))

The simple solution here is to exclude the Sophos AutoUpdate folder from the DPM backup, its quite a pain if you have to do it for a whole lot of servers but not much else that can be done!
