Protected system state file 'filename' is backed up to the drive file space, not system state file space.
Files protected by Microsoft Windows File Protection (WFP) or Microsoft Windows Resource Protection (WRP) are part of the Microsoft Volume ShadowCopy Services (VSS) System Writer which is part of the system state. These files are normally backed up as part of the system state, not the file system on which the files reside. A problem in the operating system environment prevented the protected file named in the message text from being enumerated as a system state file and thus backed up as part of the system state. The conditions that lead to this message are not normal. In order to ensure that the file is protected, it is backed up as part of the file system on which it resides.
The file is backed up as part of the file system on which it resides.
It is possible to restore the system using the file system and system state backups. However the conditions that prevent the system state files from being correctly enumerated should be addressed. On Microsoft Windows 2008 and Microsoft Windows 2008 R2 you can use the DiskShadow utility sub-command LIST WRITERS DETAILED to enumerate the system state files. On other versions of Microsoft Windows you can use the vshadow utility with the -wm2 option to enumerate the system state files. Verify that the file indicated in this message is not listed. Note: vshadow is a utility that you can obtain from Microsoft. After confirming that the files are not enumerated, contact your operating system technical support for help to diagnose and resolve the issue that prevents the file from being correctly enumerated as part of the system state.
