我备份了一个数据库:

BACKUP DATABASE MyDatabase
TO DISK = 'MyDatabase.bak'
WITH INIT --overwrite existing

然后试图恢复它:

RESTORE DATABASE MyDatabase
   FROM DISK = 'MyDatabase.bak'
   WITH REPLACE --force restore over specified database

现在数据库处于还原状态。

有些人推测，这是因为备份中没有日志文件，需要使用以下方法前滚:

RESTORE DATABASE MyDatabase
WITH RECOVERY 

当然，这是行不通的:

Msg 4333, Level 16, State 1, Line 1
The database cannot be recovered because the log was not restored.
Msg 3013, Level 16, State 1, Line 1
RESTORE DATABASE is terminating abnormally.

在灾难性的情况下，你想要的是一个无法工作的恢复。

备份包含数据文件和日志文件:

RESTORE FILELISTONLY 
FROM DISK = 'MyDatabase.bak'
