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。

在SQL Server 2008 R2操作系统中，将数据库以文件的形式备份到文件夹中。 然后选择“Database”文件夹中的恢复选项。 在向导中输入目标数据库中需要的新名称。 然后选择“从文件恢复”并使用刚才创建的文件。 我就这样做了，它非常快(我的DB很小，但仍然) 巴勃罗。

该程序以不同的名称将数据库复制到同一服务器。我依赖于这个网站上给出的例子，并进行了一些改进。

解决方案，基于这条评论:https://stackoverflow.com/a/22409447/2399045。 只需设置:DB名称，临时文件夹，DB文件文件夹。 运行后，您将拥有名称为“sourceDBName_yyyy-mm-dd”格式的DB副本。

-- Settings --
-- New DB name will have name = sourceDB_yyyy-mm-dd
declare @sourceDbName nvarchar(50) = 'MyDbName';
declare @tmpFolder nvarchar(50) = 'C:\Temp\'
declare @sqlServerDbFolder nvarchar(100) = 'C:\Databases\'

--  Execution --
declare @sourceDbFile nvarchar(50);
declare @sourceDbFileLog nvarchar(50);
declare @destinationDbName nvarchar(50) = @sourceDbName + '_' + (select convert(varchar(10),getdate(), 121))
declare @backupPath nvarchar(400) = @tmpFolder + @destinationDbName + '.bak'
declare @destMdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '.mdf'
declare @destLdf nvarchar(100) = @sqlServerDbFolder + @destinationDbName + '_log' + '.ldf'

SET @sourceDbFile = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 0)

SET @sourceDbFileLog = (SELECT top 1 files.name 
                    FROM sys.databases dbs 
                    INNER JOIN sys.master_files files 
                        ON dbs.database_id = files.database_id 
                    WHERE dbs.name = @sourceDbName
                        AND files.[type] = 1)

BACKUP DATABASE @sourceDbName TO DISK = @backupPath

RESTORE DATABASE @destinationDbName FROM DISK = @backupPath
WITH REPLACE,
   MOVE @sourceDbFile     TO @destMdf,
   MOVE @sourceDbFileLog  TO @destLdf

来自SSMS:

1 -备份原始数据库到。bak文件(your_source_db -> Task -> Backup)。

2 -右键点击“数据库”和“恢复数据库”

3 -设备>…(按钮)>添加>选择your_source_db.bak

4 -在“General”选项卡，在“Destination”部分，将“Database”your_source_db重命名为new_name_db

5 -在“文件”选项卡，勾选“重新定位所有文件到文件夹”，

在“还原为”列中重命名两个lignes，以保持与new_name_db(。mdf _log.ldf)

6 -在“选项”选项卡，“恢复选项”部分，勾选两个拳头选项(“覆盖…”'， '保存…')，对于'恢复状态':'恢复与恢复'

也要确保在“尾日志备份”部分的选项是不勾选的，以避免保持源db在“恢复状态”!

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。
