-----自动定期更名备份数据库　作者：周承昊 2005.4.26
--首先在数据库上备份一次，备份时选择“调度”，然后设置其调度时间等
--然后在SQL企业管理器－>管理－>SQLServer代理－>作业－>找到刚建的那个调度
--双击该调度作业－>步骤－>第一步，然后按需要输入下边这些SQL脚本
Declare @s varchar(254)
Select @s= Convert(VarChar(50),GetDate(),120)		--ODBC标准格式
Select @s=Replace( Replace( Replace(@s,'-','_'), ' ',''), ':','_')
Select @s='D:\SysData\Backup\Easter3M'+@s
BACKUP DATABASE [Easter3M] TO  DISK = @s WITH  INIT ,  NOUNLOAD ,  NAME = N'Easter3M 备份',  NOSKIP ,  STATS = 10,  NOFORMAT
