Microsoft has introduced a new concept in storage – “Cool” blob storage. This storage is designed for archive scenarios where availability isn’t quite as demanding and where access requirements are lower. Cool storage is significantly cheaper to store data but more expensive to access it, ideal for long term archives, backups, etc. where the need is primarily storage and not frequent access.
Storage prices are significantly cheaper in cool storage, as low as $0.01 per GB compared to $0.024 per GB.
Third party backup software providers such as Commvault and Veritas will support selection of either Hot or Cool storage within their backup solutions.
