How to SELECT * into a SQL table incremntally by date?

Question

I have a SQL Server table called "tblProducts".
Sometimes I backup this table by making a copy of it with this simple query:
SELECT *
INTO [test01].[dbo].[tblProducts_20141206]
FROM [test01].[dbo].[tblProducts]
Every time when making a backup, the date is included in the table name.
I would like to create a SQL Job that runs this kind of query once every week.
Is it possible to maybe in a stored procedure or declaring a variable to achieve this that allows the backed-up table name to be named like [tblProducts_todaysDate]?
Thanks.

hi ,dchencm
i just want to point out the some bad effect of this pratice
first point is
when your db has be corrupt，your backup out of work
i think you should backup your table to other db ensure that when your db has be corrupt you still have real backup
just like
SELECT *
INTO [test01_backup].[dbo].[tblProducts_20141206]
FROM [test01].[dbo].[tblProducts]
another point is your pratice is total amount of backup not  incremental backup
when your table  become bigger and bigger ,and then the number of record reach several million or several ten million or several hundred million, you must import all  data the table have
so, this is not a good idea
i just suggest  apply replication or logshipping etc to copy the diff data the table proceded is the better
 the steps of detail  as following
step 1
USE [test01]
GO
/****** 对象: StoredProcedure [dbo].[sp_ImportBackupData] 脚本日期: 12/25/2010 16:47:49 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[sp_importbackupdata]
AS
BEGIN
BEGIN
DECLARE @date DATETIME ,
@sql VARCHAR(1000)
SET @date = GETDATE()
SET @sql = 'SELECT * INTO [test01].[dbo].[tblProducts_'
+ CONVERT(VARCHAR(8), @date, 112)
+ '] FROM [test01].[dbo].[tblProducts]'
EXEC (@Sql)
END
END
step 2
USE [msdb]
GO
/****** 对象: Job [import data] 脚本日期: 02/22/2011 09:22:44 ******/
BEGIN TRANSACTION
DECLARE @ReturnCode INT
SELECT @ReturnCode = 0
/****** 对象: JobCategory [Database Engine Tuning Advisor] 脚本日期: 02/22/2011 09:22:44 ******/
IF NOT EXISTS (SELECT name FROM msdb.dbo.syscategories WHERE name=N'Database Engine Tuning Advisor' AND category_class=1)
BEGIN
EXEC @ReturnCode = msdb.dbo.sp_add_category @class=N'JOB', @type=N'LOCAL', @name=N'Database Engine Tuning Advisor'
IF (@@ERROR <> 0 OR @ReturnCode <> 0) GOTO QuitWithRollback

Certainly， you can edit it for yourself
