SQL异地备份

 首先准备工作：开启SQL server Agent 服务，外围配置开启 xp_cmdshell，设置远程备份目标文件夹共享

--获取操作权限
Exec master..xp_cmdshell 'net use \\ipaddress\backupFolder password /User:ip\Administrator'
/*
  PS:调用xp_cmdshell需要在SQL外围配置器中设置允许xp_cmdshell
 net use \\192.168.1.108\easyworktools\test  远程IP+备份文件夹
  admin@cti 登录密码
  /User:192.168.1.108\Administrator  登录用户
*/
--备份名称，年-月-日.bak
DECLARE @bakName VARCHAR(200)
SET @bakName='\\ipaddress\folder\'+CONVERT(VARCHAR,YEAR(GETDATE()))+'-'+CONVERT(VARCHAR,MONTH(GETDATE()))+'-'+CONVERT(VARCHAR,DAY(GETDATE()))+'.bak'
Backup Database [test] to Disk = @bakName
--删除映射
exec master..xp_cmdshell 'net use \\ipaddress\folder\  /delete'
