SQL日志备份 - “最近不适用于数据库”

Question

我有一个相当大的数据库（用于我们的硬件设置），并且试图让镜像继续下去。我似乎无法将主数据库和镜像数据库同步到足够近以允许镜像启动。

完整备份大约需要10分钟，再加上8分钟才能将BAK传输到镜像服务器，另外需要10分钟才能将其恢复。所以，要尽量把事情尽可能靠近在一起，我能我也照本宣科了以下工作：

**在主**

SET NOCOUNT ON 
USE master 


DECLARE @dbFileName  VARCHAR(75) 
     , @logFileName VARCHAR(75) 

SELECT @dbFileName  = 'F:\SQL_Backups\RIVFramework_Prod1\Mirror\prod1.mdf.' + CONVERT(VARCHAR(10), GETDATE(), 102) + '.bak' -- formats date in YYYY.MM.DD -- 
SELECT @logFileName = 'F:\SQL_Backups\RIVFramework_Prod1\Mirror\prod1.ldf.' + CONVERT(VARCHAR(10), GETDATE(), 102) + '.bak' -- formats date in YYYY.MM.DD -- 

SELECT @dbFileName  
SELECT @logFileName  

/** 
** 1 - Make sure your database is in full recovery mode 
**/ 
ALTER DATABASE RIVFramework_Prod1 
SET RECOVERY FULL 

/** 
** 2 - Backup the database 
**/ 
BACKUP DATABASE RIVFramework_Prod1 
TO DISK = @dbFileName 

/** 
** 3 - Backup the database log 
**/ 
BACKUP LOG RIVFramework_Prod1 
TO DISK = @logFileName 

SET NOCOUNT OFF 

**复制文件**

---

***注意：我更改了主数据库恢复语句，以便日后文件能够正确恢复。改变

WITH NORECOVERY,

到

WITH REPLACE, NORECOVERY,

---

**上镜**

SET NOCOUNT ON 
USE master 

/** 
** Restore backup to Mirror server: 
** MIRROR SERVER 
** 4 - Restore to the mirror database with no recovery option 
**/ 
RESTORE DATABASE RIVFramework_Prod1 
FROM DISK = 'F:\XFer\prod1.mdf.2011.06.10.bak' 
WITH REPLACE, NORECOVERY, -- You need to have both options in here so the later log file restore works. 
MOVE 'RIVFramework_Prod1' TO 'F:\SQL2008\RIVFramework_Prod1.mdf', 
MOVE 'CampaignAnalytics' TO 'F:\SQL2008\RivFramework_Prod1_CampaignAnalytics.ndf', 
MOVE 'SalesAnalytics' TO 'F:\SQL2008\RivFramework_Prod1_SalesAnalytics.ndf', 
MOVE 'RIVFramework_Prod1_log' TO 'G:\SQL2008\RIVFramework_Prod1_log.ldf' 


/** 
** 5 - Restore the mirror database logs with no recovery 
**/ 
RESTORE LOG RIVFramework_Prod1 
FROM DISK = 'F:\XFer\prod1.ldf.2011.06.10.bak' 
WITH NORECOVERY 
GO 

现在，我约30分钟不同步。所以，我做的：

**在主**

SET NOCOUNT ON 
USE master 


DECLARE @logFileName VARCHAR(75) 

SELECT @logFileName = 'F:\SQL_Backups\RIVFramework_Prod1\Mirror\prod1.ldf.a.' + CONVERT(VARCHAR(10), GETDATE(), 102) + '.bak' -- formats date in YYYY.MM.DD -- 

SELECT @logFileName  

/** 
** 1 - Make sure your database is in full recovery mode 
**/ 
ALTER DATABASE RIVFramework_Prod1 
SET RECOVERY FULL 

/** 
** 3 - Backup the database log 
**/ 
BACKUP LOG RIVFramework_Prod1 
TO DISK = @logFileName 

SET NOCOUNT OFF 

**复制文件**

**上镜**

SET NOCOUNT ON 
USE master 

/** 
** 5 - Restore the mirror database logs with no recovery 
**/ 
RESTORE LOG RIVFramework_Prod1 
FROM DISK = 'F:\XFer\prod1.ldf.a.2011.06.10.bak' 
WITH NORECOVERY 
GO 

而且我迎接以下错误：

Msg 4305, Level 16, State 1, Line 53 The log in this backup set begins at LSN 61063000000325800001, which is too recent to apply to the database. An earlier log backup that includes LSN 61063000000117800001 can be restored. Msg 3013, Level 16, State 1, Line 53 RESTORE LOG is terminating abnormally.

任何想法我失踪？

TIA

在你只想做一个完全备份的第一个脚本。 在这两个脚本中，不要每次都将恢复设置为满，但要检查它是否已全部完成，如果尚未停止，则需要确定谁正在更改恢复模式。 在镜像中使用您显示的脚本仅恢复完整备份 返回到prinicpal并执行日志备份 在镜像中使用norecovery恢复日志。
