Symptoms

Consider the following scenario:

  • You have a computer that is running one of the following operating systems:

    • Windows Server 2008 R2

    • Windows 7

    • Windows Server 2008

    • Windows Vista

  • You install an application that uses transactional logging on the computer, such as Microsoft SQL Server or Microsoft Exchange Server.

  • The log file of the application is saved on the root folder of a mount point.

  • You try to use the Windows backup engine to back up the application.


In this scenario, the backup operation fails, and you receive the following error message:

Log of files successfully backed up
'path of Log-File'
Log of files for which backup failed
'path of Log-File'
Failure in a Volume Shadow Copy Service operation.
ERROR - Volume Shadow Copy Service operation error <0x800423f0> the shadow copy set only contains only a subset of the volumes needed to correctly backup the selected components of the writer.


After you receive this error message, you run the Vssadmin list writers command. This results in the application writer being in the following state:

State: [8] Failed
Last error: Inconsistent shadow copy


Cause

This problem occurs because the XML metadata that is created by the log writer on the computer differs from the metadata that the Windows backup engine expects. If the file path for the log files points to the root of a mount point, the Windows backup engine expects the physical path for the log files to end with a trailing backslash. However, the log writer returns the physical path information without a trailing backslash. Therefore, this causes the issue to occur.

Problems with the log writer can also cause a different problem that is documented in the following Microsoft Knowledge Base article:

977179 You receive an "0x800423f0" error message when you perform system state backups on the passive node of Windows Server 2008-based Exchange Server 2007 CCR clusters
