PutPlace provides an online backup service using Amazon Web Services including EC2, S3, and Elastic IPs. They have been using AWS in production since January 2008 and currently back up around 15,000 user files daily. Their monthly AWS costs are approximately $1,200 for EC2 and $470 for S3, which is doubling each month. To cut costs, they partition their database across smaller EC2 instances and use compression and deduplication to reduce storage needs.
