A couple of weeks ago, during the BUILD conference, and interesting functionality for Windows Azure was revealed: Geo-Replication of the data in the Windows Azure Storage.
It basically provides data replication for all your Windows Azure Blob and Table data at no additional cost. Your data stays in the same regions as it is replicated between two locations hundreds of km apart but still in the same region (i.e. North and West Europe, …). It is provided for additional data durability in the case of major data center disaster – so try achieving that yourself especially at the price of 0€…
Amazing functionality, providing a live back-up of all of your data at no charge!? Read more about it here and start putting your data into the clouds 
. It will soon turn out to be the safest and most reliable place!
