Cause

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

Resolution

To resolve this issue follow the steps below:

1. First check for unresolvable SIDs in the 'Administrators' group on the SCVMM source machine. If any exist, delete them.

2. Open regedit and locate 'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList'

3. Under the ProfileList subkey, delete any subkey that is named SID.bak.

Note: SID is a placeholder for the security identifier (SID) of the user account that is experiencing the problem. The SID.bak subkey should contain a ProfileImagePath registry entry that points to the original profile folder of the user account that is experiencing the problem.

More Information

Shadow Copy Optimization Writer
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.

The writer name string for this writer is "Shadow Copy Optimization Writer".

The writer ID for the shadow copy optimization writer is 4DC3BDD4-AB48-4D07-ADB0-3BEE2926FD7F.
