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
============= ===============
MyDatabase C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase.mdf
MyDatabase_log C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase_log.LDF
I had a similar issue with restoring using SQL Management Studio. I tried to restore a backup of the database to a new one with a different name. At first this failed and after fixing the new database's file names it was successfully performed - in any case the issue I'm describing re-occurred even if I got this right from the first time. So, after the restoration, the original database remained with a (Restoring...) next to its name. Considering the answers of the forum above (Bhusan's) I tried running in the query editor on the side the following:
RESTORE DATABASE "[NAME_OF_DATABASE_STUCK_IN_RESTORING_STATE]"
这解决了问题。一开始我遇到了麻烦，因为数据库名称包含特殊字符。我通过在周围添加双引号来解决这个问题-单引号将不起作用，给出“错误的语法接近……”错误。
这是我尝试解决这个问题(数据库处于恢复状态)的最小解决方案，我希望它可以应用到更多的情况。
执行RESTORE DATABASE/RESTORE LOG命令时，默认使用WITH RECOVERY选项。如果你被困在“恢复”过程中，你可以通过执行以下命令将数据库恢复到在线状态:
RESTORE DATABASE YourDB WITH RECOVERY
GO
如果需要恢复多个文件，CLI命令分别需要WITH NORECOVERY和WITH RECOVERY -只有命令中的最后一个文件需要WITH RECOVERY才能使数据库恢复在线:
RESTORE DATABASE YourDB FROM DISK = 'Z:\YourDB.bak'
WITH NORECOVERY
GO
RESTORE LOG YourDB FROM DISK = 'Z:\YourDB.trn'
WITH RECOVERY
GO
你也可以使用SQL Server Management Studio向导:
也有虚拟恢复过程，但你必须使用第三方解决方案。通常，您可以使用数据库备份作为实时在线数据库。ApexSQL和Idera都有自己的解决方案。由SQL Hammer审查关于ApexSQL恢复。如果要处理大量备份，虚拟恢复是一个很好的解决方案。恢复过程要快得多，还可以节省磁盘驱动器上的大量空间。你可以看看这里的信息图进行一些比较。
