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

我今天在虚拟机SQL Server上遇到了这个问题。我试图恢复一个1.8GB的数据库,它被ASYNC_IO_COMPLETION卡在0%。

我尝试了多次,将.bak文件移动到我要恢复到的驱动器;甚至试图恢复另一个大小<400MB的不相关数据库。

我在这个帖子上尝试了所有的方法,都没有成功。

然后我遇到了恢复卡在DBA的ASYNC_IO_COMPLETION和答案为我工作。

启用“立即文件初始化”并重新启动SQL Server,然后重试恢复。SSMS GUI几乎立即显示进度百分比,如下所示:

Select percent_complete,* From sys.dm_exec_requests

我的猜测是VM后面的存储非常慢,或者有故障。

RESTORE DATABASE {DatabaseName}
   FROM DISK = '{databasename}.bak'
   WITH REPLACE, RECOVERY

这个方法奏效了:

我有一个情况,我的数据库显示恢复状态,我不能运行任何查询,不能与我们的软件连接。

为了摆脱这种情况,我所做的是:

停止windows服务中的所有SQL相关服务。 我打开了数据文件夹,其中Ldf和Mdf文件驻留在SQL目录中,通常是这样的: “C: \程序文件 ***********\ 该软件\数据 然后我复制了数据库的Ldf和Mdf文件: (数据库名称)。MDF和[db name]_log.ldf

我把这两个文件都复制到另一个文件夹。

Then I started all the SQL related services (in step 1) again from windows services. Started my MS SQL Management studio with normal login. Right click on the culprit database and hit DELETE (to delete the database at all). All the LDF and MDF files related to this database have gone from DATA folder (mentioned in step 2). Created a new database with the same name (same name of the one I deleted in step 6 - the culprit database). Then [database name]->right click -> tasks -> Take Offline. I then Copied both the files (from step 3) back to the DATA folder (step 2). [database name]->right click -> tasks -> Bring Online.

如果您想从备份文件恢复SQL Server数据库,可以使用以下脚本:

RESTORE DATABASE [MyDatabase] -- which database to restore
FROM DISK = N'X:\MyDatabase.bak' -- location of the database backup
WITH 
    FILE = 1, -- restore from a backup file
    -- declare where the file groups should be located (can be more than two)
    MOVE N'MyDatabase_Data' TO N'D:\SSDPATH\MyDatabase.mdf',
    MOVE N'MyDatabase_Log' TO N'E:\HDDPATH\MyDatabase.ldf',
    -- Tape option; only relevant if you backup from magnetic tape
    NOUNLOAD,
    -- brings the database online after the database got restored
    -- use this option when you don't want to restore incremental backups
    -- use NORECOVERY when you want to restore differential and incremental backup files
    RECOVERY,
    -- replace existing database with the backup 
    -- deletes the existing database
    REPLACE, 
    -- print log message for every 1 percent of restore
    STATS = 1;

好吧,我有类似的问题,就像在Pauk的情况下一样,这是由服务器在恢复时耗尽磁盘空间引起的,因此导致了永久恢复状态。 如何在不停止SQL Server服务的情况下结束此状态?

我找到了一个解决方案:)

Drop database *dbname*

你可以这样做:

停止服务(MSSQLSERVER); 重命名或删除数据库和日志文件(C:\Program files \Microsoft SQL Server\MSSQL.1\MSSQL\Data…)或任何你有文件的地方; 启动服务(MSSQLSERVER); 删除有问题的数据库; 重新恢复数据库。
