Archive Stored Procedure

My SP looks like this that originally populates the record set.

CREATE PROCEDURE dbo.sp_insert_file


@KBID int,
@rev int,
@filename nvarchar(50),
@moddate datetime,
@owner nvarchar(50),
@author nvarchar(50)


As

INSERT INTO KBFile
(KBID, rev, filename, moddate, owner, author)
VALUES (@KBID,@rev,@filename,@moddate,@owner, @author)
GO

I need to have a stored procedure that will select a recordset based on KBID(PK) and archive the entire record set to another table. I then need to be able to UPDATE the individual records for this record set in the KBFile table.

I am trying to create an 'audit' trail while maintaining previous records.

Can someone point me in the right direction?
