Cause

Volume Shadow Service (VSS) 'Shadow Copy Optimization Writer' is not fuctioning correctly. In the event log above the issue involves resolving a SID.

 
Beginning with Windows Vista and Windows Server 2008, this writer deletes certain files from volume shadow copies. This is done to minimize the impact of Copy-on-Write I/O during regular I/O on these files on the shadow-copied volume. The files that are deleted are typically temporary files or files that do not contain user or system state.
