SBS Backup Fails on VSS 0x800423f4 error Part 2
In working on the backup issues we noticed that there is a direct corolation between SQL Server and the backup not working. In the Event Viewer we are getting the following when the backup should start:
Event Type: ErrorEvent Source: VSSEvent Category: NoneEvent ID: 6013Date: 3/17/2006Time: 10:01:52 PMUser: N/AComputer: SERVER1Description:Sqllib error: OLEDB Error encountered calling ICommandText::Execute. hr = 0x80040e14. SQLSTATE: 42000, Native Error: 3013Error state: 1, Severity: 16Source: Microsoft OLE DB Provider for SQL ServerError message: BACKUP DATABASE is terminating abnormally.SQLSTATE: 42000, Native Error: 3202Error state: 1, Severity: 16Source: Microsoft OLE DB Provider for SQL ServerError message: Write on '{6982A5F8-27AD-45DF-A816-53522621B2F4}1' failed, status = 995. See the SQL Server error log for more details.

So it appears that SQL is our culprit with our failed NT backups. Microsoft has suggested we make sure that the System Account is running as the log on service for MSSQL$Sharepoint and MSSQL$Monitoring as well as for the default MSSQL instance. It appears to be so. We'll be following some more as we narrow down what is happening. It also seems to now be happening sporadically as last night all backups worked. Go figure.
