EXEC sp_configure 'show advanced options', 1;RECONFIGURE;

EXEC sp_configure 'xp_cmdshell', 1;RECONFIGURE;

declare @machine nvarchar(50) = '192.168.11.10' --服务器IP

declare @path nvarchar(50) = 'DBBackup\KH_01' --服务器共享目录名称

declare @user nvarchar(50) = 'admin' --服务器的用户名

declare @pwd nvarchar(50) = 'Admin1@3' --服务器的密码

declare @database nvarchar(50) = 'KH_01' --本地要备份的数据库名称

if left(@path,1) != '\' set @path = '\'+@path

declare @sql nvarchar(800) = 'net

use \\'+@machine+@path+' "'+@pwd+'"

/user:'+@machine+'\'+@user

--建立连接类似：'net use \\192.168.200.175\208bf " " /user:192.168.200.175\happy'

Exec KH_01..xp_cmdshell @sql

declare @date datetime = getdate();

Declare @fileName nvarchar(200) = '\\'+@machine+@path+'\'+@database + replace(Convert(nvarchar,@date,120 ) ,':','_') + '.bak'

--备份数据库

Backup Database KH_01 To disk = @fileName With Format

set @sql = 'net use \\'+@machine+@path+'

/delete'

--断开连接类似：'net use \\192.168.200.175\208bf /delete'

Exec KH_01..xp_cmdshell @sql
