YourSQLDba可以将数据库备份到网络路径(共享路径),这个也是非常灵活的一个功能,以前一直没有使用过这个功能,最近由于一个需求,于是我测试了一下YourSQLDba备份到网络路径,中间遇到了一些问题,遂整理如下。
测试环境:
操作系统: Windows Server Standard 2012
数据库版本: SQL SERVER 2014
1:设置共享路径权限
这一步很简单,也非常好理解。共享路径需要给某些特定用户才能访问,例如某个域账号。在此略过。
2:映射网络驱动器。
映射网络驱动器,顾名思义,就是将局域网内的一个共享文件夹作为一个虚拟的网络硬盘,然后将该网络硬盘映射到本地计算机,然后我们就可以在本地计算机上访问该共享文件夹
3:然后使用Exec YourSQLDba.Maint.CreateNetworkDriv设置网络路径。
sp_configure 'show advanced option', 1;
go
reconfigure;
go
sp_configure 'xp_cmdshell', 1;
go
reconfigure;
go
Exec YourSQLDba.Maint.CreateNetworkDrives
@DriveLetter = 'S:\'
, @unc = '\\192.168.7.146\YourSQLDBABAK\Server1'
设置网络路径,必须开启数据库“xp_cmdshell”选项,否则就会有如下错误。
Exec YourSQLDba.Maint.CreateNetworkDrives
@DriveLetter = 'S:\'
@unc = '\\192.168.7.146\YourSQLDBABAK\Server1'
息 15123,级别 16,状态 1,过程 sp_configure,第 62 行
he configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.
et use S: /Delete
et use S: \\192.168.7.146\YourSQLDBABAK\Server1
5123: The configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.
息 15123,级别 16,状态 1,过程 sp_configure,第 62 行
he configuration option 'xp_cmdshell' does not exist, or it may be an advanced option.
如果你遇到下面错误信息,请检查你SQL SERVER服务的登录账号是否是NT账号或域账号。如果是默认的NT Service\MSSQLSERVER则会遇到该错误提示。
可以讲SQL Server服务的登录账号改为共享路径设置权限的域账号。那么接下来,修改一下作业YourSQLDba_FullBackups_And_Maintenance里面的配置信息就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 =
'
'
在测试过程中发现YourSQLDba备份到共享路径对网络环境要求比较高,有几次在网络出现连续掉两个或两个以上包的时候,备份进程就出错,检查出错信息,发现如下错误信息。
<;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>
