Sql Server远程备份数据库方式一

--注意：异地备份数据库，需要先开启备份文件夹的网络共享，数据库选择master
--打开允许执行xp_cmdshell 
EXEC sp_configure \'xp_cmdshell\',1

exec master..xp_cmdshell \'net use \192.168.0.139\DatabaseBackup password /user:192.168.0.139\administrator\'

backup database myDatabase to disk=\'\192.168.0.139\DatabaseBackup\myDatabase_04_05.bak\' with init

exec master..xp_cmdshell \'net use \192.168.0.139\DatabaseBackup /delete\'

--关闭允许执行xp_cmdshell
EXEC sp_configure\'xp_cmdshell\', 0

如果提示无权限错误，请先执行以下脚本，注意数据库要选master

EXEC sp_configure \'show advanced options\', 1
GO
RECONFIGURE WITH OVERRIDE
