如何通过bat文件备份sql server 2014 db数据？

Question

我使用此查询在bat文件到备份数据库，

sqlcmd -S .\MSSQLSERVER -E -Q "EXEC sp_BackupDb @backupLocation='D:\SQLBackups\', @databaseName='TestDb', @backupType='F'" pause 

它抛出这个错误，

Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : SQL Server Network Inte rfaces: Connection string is not valid [87]. Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : Login timeout expired. Sqlcmd: Error: Microsoft ODBC Driver 11 for SQL Server : A network-related or in stance-specific error has occurred while establishing a connection to SQL Server . Server is not found or not accessible. Check if instance name is correct and i f SQL Server is configured to allow remote connections. For more information see SQL Server Books Online..

是否有人可以帮忙吗？提前致谢。

可以使用SQLCMD在.bat文件，使这个bakcup，在这个环节上，你有一个例子stackoverflow link

SQLCMD：

The sqlcmd utility lets you enter Transact-SQL statements, system procedures, and script files at the command prompt, in Query Editor in SQLCMD mode, in a Windows script file or in an operating system (Cmd.exe) job step of a SQL Server Agent job. This utility uses OLE DB to execute Transact-SQL batches.

这里是链接的例子和定义： msdn link definition

例如：

sqlcmd -E -S %SERVERNAME% -d master -Q "BACKUP DATABASE [%DATABASENAME%] TO DISK = N'%BACKUPFILENAME%' WITH INIT , NOUNLOAD , NAME = N'%DATABASENAME% backup', NOSKIP , STATS = 10, NOFORMAT"
