对于SQL Server 2012，使用SQL Server Management Studio，我发现从微软页面恢复到不同的数据库文件和名称的这些步骤很有用:(参考:http://technet.microsoft.com/en-us/library/ms175510.aspx)

注意，为了不覆盖现有数据库，设置步骤4和7很重要。

To restore a database to a new location, and optionally rename the database Connect to the appropriate instance of the SQL Server Database Engine, and then in Object Explorer, click the server name to expand the server tree. Right-click Databases, and then click Restore Database. The Restore Database dialog box opens. On the General page, use the Source section to specify the source and location of the backup sets to restore. Select one of the following options: Database Select the database to restore from the drop-down list. The list contains only databases that have been backed up according to the msdb backup history. Note If the backup is taken from a different server, the destination server will not have the backup history information for the specified database. In this case, select Device to manually specify the file or device to restore. Device Click the browse (...) button to open the Select backup devices dialog box. In the Backup media type box, select one of the listed device types. To select one or more devices for the Backup media box, click Add. After you add the devices you want to the Backup media list box, click OK to return to the General page. In the Source: Device: Database list box, select the name of the database which should be restored. Note This list is only available when Device is selected. Only databases that have backups on the selected device will be available. In the Destination section, the Database box is automatically populated with the name of the database to be restored. To change the name of the database, enter the new name in the Database box. In the Restore to box, leave the default as To the last backup taken or click on Timeline to access the Backup Timeline dialog box to manually select a point in time to stop the recovery action. In the Backup sets to restore grid, select the backups to restore. This grid displays the backups available for the specified location. By default, a recovery plan is suggested. To override the suggested recovery plan, you can change the selections in the grid. Backups that depend on the restoration of an earlier backup are automatically deselected when the earlier backup is deselected. To specify the new location of the database files, select the Files page, and then click Relocate all files to folder. Provide a new location for the Data file folder and Log file folder. Alternatively you can keep the same folders and just rename the database and log file names.

SQL Server 2008 R2:

对于您希望“从不同数据库的备份恢复:”的现有数据库，请执行以下步骤:

From the toolbar, click the Activity Monitor button. Click processes. Filter by the database you want to restore. Kill all running processes by right clicking on each process and selecting "kill process". Right click on the database you wish to restore, and select Tasks-->Restore-->From Database. Select the "From Device:" radio button. Select ... and choose the backup file of the other database you wish to restore from. Select the backup set you wish to restore from by selecting the check box to the left of the backup set. Select "Options". Select Overwrite the existing database (WITH REPLACE) Important: Change the "Restore As" Rows Data file name to the file name of the existing database you wish to overwrite or just give it a new name. Do the same with the log file file name. Verify from the Activity Monitor Screen that no new processes were spawned. If they were, kill them. Click OK.

您可以创建一个新的数据库，然后使用“恢复向导”启用覆盖选项或:

查看备份文件内容:

RESTORE FILELISTONLY FROM DISK='c:\your.bak'

注意结果中.mdf和.ldf的逻辑名称，然后:

RESTORE DATABASE MyTempCopy FROM DISK='c:\your.bak'
WITH 
   MOVE 'LogicalNameForTheMDF' TO 'c:\MyTempCopy.mdf',
   MOVE 'LogicalNameForTheLDF' TO 'c:\MyTempCopy_log.ldf'

这将使用your.bak的内容创建数据库MyTempCopy。

(不要创建MyTempCopy，它是在恢复过程中创建的)

示例(恢复名为'creditline'的db的备份到'MyTempCopy'):

RESTORE FILELISTONLY FROM DISK='e:\mssql\backup\creditline.bak'

>LogicalName
>--------------
>CreditLine
>CreditLine_log

RESTORE DATABASE MyTempCopy FROM DISK='e:\mssql\backup\creditline.bak'
WITH 
   MOVE 'CreditLine' TO 'e:\mssql\MyTempCopy.mdf',
   MOVE 'CreditLine_log' TO 'e:\mssql\MyTempCopy_log.ldf'

>RESTORE DATABASE successfully processed 186 pages in 0.010 seconds (144.970 MB/sec).

用“复制数据库”选项从数据库中复制一个不同的名称 备份新复制的数据库 恢复它!

以下是我从各种文章中拼凑出来的内容，使用备份和恢复来复制数据库，并使用move来修复物理位置，使用额外的sql来修复逻辑名称。

/**

 *
 * Usage: Update the @NewDatabase value to the database name to create or reset.
 */

DECLARE @NewDatabase SYSNAME = 'new_db';

-- Set up
USE tempdb;

DECLARE @TemplateBackups SYSNAME = 'TemplateBackups';
DECLARE @TemplateDatabase SYSNAME = 'template_db';
DECLARE @TemplateDatabaseLog SYSNAME = @TemplateDatabase + '_log';

-- Create a backup of the template database
BACKUP DATABASE @TemplateDatabase TO DISK = @TemplateBackups WITH CHECKSUM, COPY_ONLY, FORMAT, INIT, STATS = 100;

-- Get the backup file list as a table variable
DECLARE @BackupFiles TABLE(LogicalName nvarchar(128),PhysicalName nvarchar(260),Type char(1),FileGroupName nvarchar(128),Size numeric(20,0),MaxSize numeric(20,0),FileId tinyint,CreateLSN numeric(25,0),DropLSN numeric(25, 0),UniqueID uniqueidentifier,ReadOnlyLSN numeric(25,0),ReadWriteLSN numeric(25,0),BackupSizeInBytes bigint,SourceBlockSize int,FileGroupId int,LogGroupGUID uniqueidentifier,DifferentialBaseLSN numeric(25,0),DifferentialBaseGUID uniqueidentifier,IsReadOnly bit,IsPresent bit,TDEThumbprint varbinary(32));
INSERT @BackupFiles EXEC('RESTORE FILELISTONLY FROM DISK = ''' + @TemplateBackups + '''');

-- Create  the backup file list as a table variable
DECLARE @NewDatabaseData VARCHAR(MAX);
DECLARE @NewDatabaseLog VARCHAR(MAX);

SELECT @NewDatabaseData = PhysicalName FROM @BackupFiles WHERE Type = 'D';
SELECT @NewDatabaseLog = PhysicalName FROM @BackupFiles WHERE Type = 'L';

SET @NewDatabaseData = REPLACE(@NewDatabaseData, @TemplateDatabase, @NewDatabase);
SET @NewDatabaseLog = REPLACE(@NewDatabaseLog, @TemplateDatabase, @NewDatabase);

RESTORE DATABASE @NewDatabase FROM DISK = @TemplateBackups WITH CHECKSUM, RECOVERY, REPLACE, STATS = 100,
   MOVE @TemplateDatabase TO @NewDatabaseData,
   MOVE @TemplateDatabaseLog TO @NewDatabaseLog;

-- Change Logical File Name
DECLARE @SQL_SCRIPT VARCHAR(MAX)='
    ALTER DATABASE [{NewDatabase}] SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
    ALTER DATABASE [{NewDatabase}] MODIFY FILE (NAME=N''{TemplateDatabase}'', NEWNAME=N''{NewDatabase}'');
    ALTER DATABASE [{NewDatabase}] MODIFY FILE (NAME=N''{TemplateDatabase}_log'', NEWNAME=N''{NewDatabase}_log'');
    ALTER DATABASE [{NewDatabase}] SET MULTI_USER WITH ROLLBACK IMMEDIATE;
    SELECT name AS logical_name, physical_name FROM SYS.MASTER_FILES WHERE database_id = DB_ID(N''{NewDatabase}'');
';
SET @SQL_SCRIPT = REPLACE(@SQL_SCRIPT, '{TemplateDatabase}', @TemplateDatabase);
SET @SQL_SCRIPT = REPLACE(@SQL_SCRIPT, '{NewDatabase}', @NewDatabase);
EXECUTE (@SQL_SCRIPT);

如果不存在数据库，我使用以下代码:
