一段脚本实现自动备份并保存最近几天的SQL数据库

<div class="codetitle"><a style="CURSOR: pointer" data="10337" class="copybut" id="copybut10337" onclick="doCopy('code10337')"> 代码如下:<div class="codebody" id="code10337">
DECLARE @filename VARCHAR(255)
DECLARE @date DATETIME
SELECT @date=GETDATE()
SELECT @filename = 'G:\存放位置\数据库名称-'+CAST(DATEPART(yyyy,@date) as varchar)+'-'+CAST(DATEPART(mm,@date) as varchar)+'-'+CAST(DATEPART(dd,@date) as varchar)+'.bak'
BACKUP DATABASE [数据库名称] TO DISK = @filename WITH INIT
GO DECLARE @OLDDATE DATETIME
SELECT @OLDDATE=GETDATE()-5
EXECUTE master.dbo.xp_delete_file 0,N'G:\存放位置',N'bak',@olddate,1

上面是一个备份最近5天的数据库作业脚本。
