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. YourSQLDba不能直接访问共享路径。否则会报错。
3：然后使用Exec YourSQLDba.Maint.CreateNetworkDriv设置网络路径。
sp_configure ‘show advanced option‘, 1;goreconfigure;gosp_configure ‘xp_cmdshell‘, 1;goreconfigure;goExec YourSQLDba.Maint.CreateNetworkDrives @DriveLetter = ‘S:\‘ @unc = ‘\\192.168.xxx.xxx\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.xxx.xxx\YourSQLDBABAK\Server1‘
消息 15123，级别 16，状态 1，过程 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，级别 16，状态 1，过程 sp_configure，第 62 行
The 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。
可以将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 =
‘‘
如果SQL Server服务是LocalSystem启动，YourSQLDba备份时会报如下错误信息,你需要将SQL Server服务的登录身份改为域账号
BackupDiskFile::CreateMedia: 备份设备 ‘S:\FULL_BACKUP\MsDb_[2016-07-04_Mon]_database.BAK‘ 无法create。操作系统错误 5(拒绝访问。)。
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.).Error 3013, Severity 16, level 1 : BACKUP DATABASE is terminating abnormally.
</err>
</Exec>
