这是我使用的脚本。有点棘手，但很有效。在SQL Server 2012上测试。

DECLARE @backupPath nvarchar(400);
DECLARE @sourceDb nvarchar(50);
DECLARE @sourceDb_log nvarchar(50);
DECLARE @destDb nvarchar(50);
DECLARE @destMdf nvarchar(100);
DECLARE @destLdf nvarchar(100);
DECLARE @sqlServerDbFolder nvarchar(100);

SET @sourceDb = 'db1'
SET @sourceDb_log = @sourceDb + '_log'
SET @backupPath = 'E:\DB SQL\MSSQL11.MSSQLSERVER\MSSQL\Backup\' + @sourceDb + '.bak'    --ATTENTION: file must already exist and SQL Server must have access to it
SET @sqlServerDbFolder = 'E:\DB SQL\MSSQL11.MSSQLSERVER\MSSQL\DATA\'
SET @destDb = 'db2'
SET @destMdf = @sqlServerDbFolder + @destDb + '.mdf'
SET @destLdf = @sqlServerDbFolder + @destDb + '_log' + '.ldf'

BACKUP DATABASE @sourceDb TO DISK = @backupPath

RESTORE DATABASE @destDb FROM DISK = @backupPath
WITH REPLACE,
   MOVE @sourceDb     TO @destMdf,
   MOVE @sourceDb_log TO @destLdf

您可以只创建一个新数据库，然后转到任务，导入数据，并将所有数据从您想要复制的数据库导入到刚刚创建的数据库。

这里提到的解决方案都不适合我-我使用的是SQL Server Management Studio 2014。

相反，我不得不取消“选项”屏幕中的“在恢复前进行尾日志备份”复选框:在我的版本中，默认情况下它是选中的，并阻止恢复操作完成。 取消检查后，还原操作继续进行，没有出现问题。

右键单击要克隆的数据库，单击Tasks，单击Copy database ....遵循向导，您就完成了。
