Sql Server远程备份数据库方式一（合集）

Posted 2020-12-15 九日之阳

--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 192.168.0.139DatabaseBackup password /user:192.168.0.139administrator‘
backup database myDatabase to disk=‘192.168.0.139DatabaseBackupmyDatabase_04_05.bak‘ with init
exec master..xp_cmdshell ‘net use 192.168.0.139DatabaseBackup /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
GO

 

备份数据库存储过程

USE [master]
GO
