If you delete a very important file, in many cases there is no easy to &quot;cancel&quot; the replication even after you realized your mistake!<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=367994" width="1" height="1">http://blogs.msdn.com/b/adioltean/archive/2005/02/05/367879.aspx#367947Sun, 06 Feb 2005 12:27:00 GMT91d46819-8472-40ad-a661-2c78acb4018c:367947robertThere is an other reason to continue making the traditional back-ups: software errors can never be excluded. <br>This is true for any replication mecanism. I have seen many sites go down including the back-up site because a software error caused a data base corruption on the main site which immediately caused by replication the same error to be propagated to the back-up system. That's what called a rolling disaster. <br>In fact application software companies like SAP do not recommend synchronized replication, but slightly differed replication so that if a data corruption occurs on the main site you get a chance to check what happened before applying the data replication to the back-up system.<div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=367947" width="1" height="1">
