Also remember its free to recover your entire Crashplan archive (I have 500GB with them). If you wanted to recover 500GB with Glacier it would cost $200 @10MB/s (according to someones calculation further down) You have to pay for retrieval
Not totally true, you have to pay for retrieval for 1GB and upwards per month: http://aws.amazon.com/glacier/#pricing as well as 5cent per upload/retrieval request.
