cold storage

Cold storage is the retention of inactive data that an organization rarely, if ever, expects to access.

High capacity, low cost and durability are important goals for cold storage.  Data retrieval and response time can be significantly slower for a cold storage system than for devices or systems designed for active data. Media choices for cold storage include tape or low-cost commodity hard disk drives

Object storage is one of the most common storage system types for cold data. One prominent example of a cloud service that caters to cold storage is Amazon Glacier.  Facebook has also devoted considerable attention to the hardware used for a cold storage system through the Open Compute Project.
