一段腳本實(shí)現(xiàn)自動備份并保存最近幾天的SQL數(shù)據(jù)庫

    代碼如下:
    DECLARE @filename VARCHAR(255)
    DECLARE @date DATETIME
    SELECT @date=GETDATE()
    SELECT @filename = 'G:\存放位置\數(shù)據(jù)庫名稱-'+CAST(DATEPART(yyyy,@date) as varchar)+'-'+CAST(DATEPART(mm,@date) as varchar)+'-'+CAST(DATEPART(dd,@date) as varchar)+'.bak'
    BACKUP DATABASE [數(shù)據(jù)庫名稱] 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
    上面是一個備份最近5天的數(shù)據(jù)庫作業(yè)腳本。
