SQLServer备份语句（可用于作业备份）

--完整备份

declare @name varchar(250) 
set @name=\'D:\BACKUP\ALLBACKUP\\' + convert(varchar(50),getdate(),112)+ \'mzyy.bak\'

BACKUP DATABASE [mzyy] TO DISK = @name WITH NOFORMAT, INIT, 
NAME = N\'mzyy-完整 数据库 备份\', SKIP, NOREWIND, NOUNLOAD, STATS = 10
GO


--删除完整备份


declare @dir varchar(100),@str varchar(100),@fileName varchar(30),@filepath varchar(300)
SET @dir=\'del D:\BACKUP\ALLBACKUP\\'
SET @str = LEFT(replace(replace(replace(convert(varchar,getdate()-7,20),\'-\',\'\'),\' \',\'\'),\':\',\'\'),8)
SET @fileName = \'mzyy.bak\'
SET @filepath =@dir +@str + @fileName
exec xp_cmdshell @filepath

--删除差异备份

declare @dirs varchar(100),@strs varchar(100),@fileNames varchar(30),@filepaths varchar(300)
SET @dirs=\'del D:\BACKUP\DIFFBACKUP\\'
SET @strs = LEFT(replace(replace(replace(convert(varchar,getdate()-7,20),\'-\',\'\'),\' \',\'\'),\':\',\'\'),8)
SET @fileNames = \'mzyy_DIFF.diff\'
SET @filepaths =@dirs +@strs + @fileNames
exec xp_cmdshell @filepaths

--差异备份

declare @str varchar(100)
set @str=\'D:\BACKUP\DIFFBACKUP\\'+replace(replace(replace(convert(varchar,getdate(),112),\'-\',\'\'),\' \',\'\'),\':\',\'\')+\'mzyy_DIFF.diff\'
BACKUP DATABASE [mzyy] TO DISK=@str
WITH DIFFERENTIAL,RETAINDAYS=8,NOFORMAT,NOINIT,
NAME=N\'mzyy差异备份\',SKIP,NOREWIND,
NOUNLOAD,STATS=10

注意：如果需要删除备份的话，需要开启 xp_cmdshell

语句：推荐使用语句（因为，我使用的是 SQL2008R2，没在 SQL的配置工具中找到 SQLServer外围应用配置器）

还有，记得给文件夹配置权限（不然无法识别文件夹内的备份文件）

sp_configure \'show advanced options\',1
reconfigure
go
sp_configure \'xp_cmdshell\',1
reconfigure
go

--如需关闭只需将“sp_configure \'xp_cmdshell\',1”改为“sp_configure \'xp_cmdshell\',0”即可。
