Analysis
=======
According to the event logs above, I found this might be a known issue when you back up the System State on a Windows Server 2003 x64 Edition-based computer that is running SQL Server 2000.

This problem occurs because the SQL Server 2000 Virtual Device Interface (Sqlvdi.dll) is a 32-bit DLL. The 64-bit Volume Shadow Copy Service (VSS) writer that is included with the x64 edition of Windows Server 2003 requires an x64 edition of Sqlvdi.dll to work correctly.

Solution

Please refer to the following KB article to fix the problem:
