Event ID: 2028

Symbolic Name: VSSWriterFreezeError
Message: The Microsoft Exchange Replication Service VSS writer (instance %1) failed when freezing the storage groups.
   
Explanation

This Error event indicates that the writer of the Volume Shadow Copy Service (VSS) of the Microsoft® Exchange Replication Service has successfully prepared for the backup and for taking the snapshot. However the VSS writer did not stop all I/O requests so that the snapshot could continue. The VSS writer might not have stopped all I/O requests for the following reasons:

  • The replication service could not create a temp log file for the backup.

  • The replication service could not stop I/O activity to the volumes affected by the selected backup.

   
User Action

To resolve the error, follow these steps:

  • Verify that the Microsoft Exchange Replication Service is running from the Services snap-in.

  • Run VSS backup again.

If you are not already doing so, consider running the tools that Microsoft Exchange offers to help administrators analyze and troubleshoot their Exchange environment. These tools can help you make sure that your configuration is in line with Microsoft best practices. They can also help you identify and resolve performance issues, improve mail flow, and better manage disaster recovery scenarios. Go to the Toolbox node of the Exchange Management Console to run these tools now. For more information about these tools, see Toolbox in the Exchange Server 2007 Help.
