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'
Logical Name PhysicalName
