USE [master];
GO

CREATE DATABASE db;
GO

CREATE DATABASE db2;
GO

BACKUP DATABASE db TO DISK = 'c:\temp\db.bak' WITH INIT, COMPRESSION;
GO

RESTORE DATABASE db2
  FROM DISK = 'c:\temp\db.bak'
  WITH REPLACE,
  MOVE 'db' TO 'c:\temp\db2.mdf',
  MOVE 'db_log' TO 'c:\temp\db2.ldf';

我必须在我的本地创建新的db进行测试，并且我的prod有备份。我先创建了db，并尝试在新db上运行BAK，这为我产生了这个错误。我删除了db并恢复它，同时在恢复屏幕本身提供新的db名称。恢复时自动创建db。

USE [master];
GO

CREATE DATABASE db;
GO

CREATE DATABASE db2;
GO

BACKUP DATABASE db TO DISK = 'c:\temp\db.bak' WITH INIT, COMPRESSION;
GO

RESTORE DATABASE db2
  FROM DISK = 'c:\temp\db.bak'
  WITH REPLACE,
  MOVE 'db' TO 'c:\temp\db2.mdf',
  MOVE 'db_log' TO 'c:\temp\db2.ldf';

如果您正在使用脚本方法，并且有关于LDF和MDF文件的错误，您可以首先查询备份文件中的备份集中文件的逻辑名称(和其他详细信息)，使用以下命令:

-- Queries the backup file for the file list in backup set, where Type denotes 
-- type of file. Can be L,D,F or S
-- info: https://learn.microsoft.com/en-us/sql/t-sql/statements/restore-statements-filelistonly-transact-sql
RESTORE FILELISTONLY FROM DISK = 'C:\Temp\DB_backup.bak'
GO

你会得到类似如下的结果:

然后你可以在查询中使用这些逻辑名称:

    -- Script assumes you want MDF and LDF files restored on separate drives. Modify for your scenario
    RESTORE DATABASE DB 
    FROM DISK='C:\Temp\DB_backup.bak'
    WITH REPLACE,
      MOVE 'DB' TO 'E:\MSSQL\Data\DB.mdf', -- "DB" is the mdf logical name from query above
      MOVE 'DB_log' TO 'F:\MSSQL\Logs\DB.ldf'; -- "DB_log" is LDF logical name from query above

关于RESTORE filelist的更多信息可以从SQL Server文档中找到。

这帮助我从系统驱动器导入备份文件

Create a database with the same name(preferably) as your .bak file database name Right click the database > Tasks > Restore > Database Under "Source for restore" select "From Device" Select the .bak file selecting the path from the system Select the check box for the database in the list box below Under "Select a Page" on the right Select "Options" Select the checkbox labeled "Preserve the replication settings(WITH KEEP_REPLICATION) Select the checkbox for Overwrite the existing database(WITH REPLACE) Now Go back to the General page and click OK to restore the database...

有些人把这个问题看得太复杂了。我发现这非常简单。

1)创建一个与你的.bak文件数据库名称相同的数据库

2)右键单击数据库| Tasks >恢复>数据库

3)在“还原源”下选择“从设备”

4)选择“。bak”文件

5)在下面的网格视图中选中数据库对应的复选框

6)在右侧的“选择页面”下选择“选项”

7)选中“保留复制设置(WITH KEEP_REPLICATION)”复选框

现在返回到General页面，单击OK恢复数据库…就是这样。
