YourSQLDba設置共享路徑備份

YourSQLDba能夠將數據庫備份到網絡路徑（共享路徑），這個也是很是靈活的一個功能，之前一直沒有使用過這個功能，最近因爲一個需求，因而我測試了一下YourSQLDba備份到網絡路徑，中間遇到了一些問題，遂整理以下。

測試環境：

    操做系統：  Windows Server Standard 2012

  數據庫版本：  SQL SERVER 2014

 

1：設置共享路徑權限

  

     這一步很簡單，也很是好理解。共享路徑須要給某些特定用戶才能訪問，例如某個域帳號。在此略過。

 

2：映射網絡驅動器。

映射網絡驅動器，顧名思義，就是將局域網內的一個共享文件夾做爲一個虛擬的網絡硬盤，而後將該網絡硬盤映射到本地計算機，而後咱們就能夠在本地計算機上訪問該共享文件夾. YourSQLDba不能直接訪問共享路徑。不然會報錯。

 

3：而後使用Exec YourSQLDba.Maint.CreateNetworkDriv設置網絡路徑。

sp_configure 'show advanced option', 1;

go

reconfigure;

go

sp_configure 'xp_cmdshell', 1;

go

reconfigure;

go

Exec YourSQLDba.Maint.CreateNetworkDrives

 @DriveLetter = 'S:\'  

 @unc = '\\192.168.xxx.xxx\YourSQLDBABAK\Server1' 

設置網絡路徑，必須開啓數據庫「xp_cmdshell」選項，不然就會有以下錯誤。

 

Exec YourSQLDba.Maint.CreateNetworkDrives

  @DriveLetter = 'S:\' 

, @unc = '\\192.168.xxx.xxx\YourSQLDBABAK\Server1'

 

消息 15123，級別 16，狀態 1，過程 sp_configure，第 62 行

The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.

net use S: /Delete

net use S: \\192.168.xxx.xxx\YourSQLDBABAK\Server1

15123: The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.

消息 15123，級別 16，狀態 1，過程 sp_configure，第 62 行

The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.

 

 

若是你遇到下面錯誤信息，請檢查你SQL SERVER服務的登陸帳號是不是NT帳號或域帳號。若是是默認的NT Service\MSSQLSERVER則會遇到該錯誤提示。

 

能夠將SQL Server服務的登陸帳號改成共享路徑設置權限的域帳號。那麼接下來，修改一下做業YourSQLDba_FullBackups_And_Maintenance裏面的配置信息就OK了

exec Maint.YourSqlDba_DoMaint

  @oper = 'YourSQLDba_Operator'

, @MaintJobName = 'YourSQLDba: DoInteg,DoUpdateStats,DoReorg,Full backups'

, @DoInteg = 1

, @DoUpdStats = 1

, @DoReorg = 1

, @DoBackup = 'F'

, @FullBackupPath = 'S:\FULL_BACKUP\'

, @LogBackupPath = 'S:\LOG_BACKUP\'  

-- Flush database backups older than the number of days

, @FullBkpRetDays = 1

-- Flush log backups older than the number of days

, @LogBkpRetDays =1

-- Spread Update Stats over 7 days

, @SpreadUpdStatRun =1

-- Maximum number of consecutive days of failed full backups allowed

-- for a database before putting that database (Offline).

, @ConsecutiveFailedbackupsDaysToPutDbOffline = 9999

-- Each database inclusion filter must be on its own line between the following quote pair

, @IncDb =

'

'

-- Each database exclusion filter must be on its own line between the following quote pair

, @ExcDb =

'

'

-- Each database exclusion filter must be on its own line between the following quote pair

, @ExcDbFromPolicy_CheckFullRecoveryModel =

'

' 

 

若是SQL Server服務是LocalSystem啓動，YourSQLDba備份時會報以下錯誤信息,你須要將SQL Server服務的登陸身份改成域帳號

BackupDiskFile::CreateMedia: 備份設備 'S:\FULL_BACKUP\MsDb_[2016-07-04_Mon]_database.BAK' 沒法create。操做系統錯誤 5(拒絕訪問。)。

 

在測試過程當中發現YourSQLDba備份到共享路徑對網絡環境要求比較高，有幾回在網絡出現連續掉兩個或兩個以上包的時候，備份進程就出錯，檢查出錯信息，發現以下錯誤信息。

<Exec>

  <ctx>yMaint.backups</ctx>

  <Sql>

backup database [WSS_Content_get_teams_tdc]

to disk = 'S:\FULL_BACKUP\Test_[2014-11-11_18h49m05_Tue]_database.BAK'

with Init, Format, checksum, name = 'YourSQLDba:18h49: S:\FULL_BACKUP\Test_[2014-11-11_18h49m05_Tue]_database.BAK'

</Sql>

  <err>Error 3201, Severity 16, level 1 : Cannot open backup device 'S:\FULL_BACKUP\Test_[2014-11-11_18h49m05_Tue]_database.BAK'. Operating system error 53(The network path was not found.).

</err>

</Exec>
