我有一周前的Database1备份。在调度程序中每周进行备份,我得到一个.bak文件。现在我想要处理一些数据,所以我需要将其恢复到另一个数据库- Database2。

我看到过这个问题:在同一台pc上使用不同的名称恢复SQL Server数据库,建议步骤是重命名原始db,但我不在这个选项中,因为我在生产服务器中,我不能真正做到这一点。

是否有其他方法将其恢复到Database2,或者至少如何浏览该.bak文件的数据?

谢谢。

Ps:上面链接的第二个答案看起来很有希望,但它总是以错误告终:

恢复文件列表异常终止

实际上,这比恢复到同一台服务器要简单一些。基本上,您只需浏览“恢复数据库”选项。这里有一个教程给你:

特别是因为这是一个非生产恢复,您可以放心地尝试它,而不必担心过多的细节。只需将SQL文件放在新服务器上您想要的位置,并给它起任何您想要的名称,就可以开始了。

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).

当我使用旧数据库恢复新数据库时,遇到了与本主题相同的错误。(使用.bak也会出现同样的错误) 我用新数据库的名称更改了旧数据库的名称(与此图相同)。它工作。

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。

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.
