    Error message

    Message logs in the Management Console of the Backup & Disaster Recovery appliance show the following error related to Microsoft SQL Server backup:

    MSSQL: warning: cannot connect to explicitly configured 'MSSQL10.XXXX' server instance: Failed to connect to server XXXX\MSSQL10.XXXX

    Steps to resolve

    You see the MSSQL10 instance when you enumerate the SQL databases in the backup agent on the Microsoft SQL Server.

    This is a false error message having to do with the Microsoft SQL Server plug-in searching for a database that does not exist.

    In the backup agent on the Microsoft SQL Server, make sure this database is excluded.
