It would certainly be interesting to know how much space is saved through deduplication. However, my guess is that it's very unlikely to make the difference between a viable and a non-viable company. Particularly as they had a viable business when storing data on S3 [1]. I'd expect the cost savings of moving from S3 to their own hosted storage to be far greater than those earned through deduplication.
