Nearline storage (a portmanteau of "near" and "online storage") is a term used [1] in computer science to describe an intermediate type of data storage that represents a compromise between online storage (supporting frequent, very rapid access to data) and offline storage/archiving (used for backups or long-term storage, with infrequent access to data).
Tertiary storage is also known as nearline storage because it is "near to online". The formal distinction between online, nearline, and offline storage is: [8] Online storage is immediately available for I/O. Nearline storage is not immediately available, but can be made online quickly without human intervention.
The four classes, Multi-Regional Storage, Regional Storage, Nearline Storage, and Coldline Storage, differ in their pricing, minimum storage durations, and availability. [5] Interoperability - Google Cloud Storage is interoperable with other cloud storage tools and libraries that work with services such as Amazon S3 and Eucalyptus Systems. [6]
Off-line bulk storage – Tertiary and Off-line storage. This is a general memory hierarchy structuring. Many other structures are useful. For example, a paging algorithm may be considered as a level for virtual memory when designing a computer architecture, and one can include a level of nearline storage between online and offline storage.
Nearline storage is typically less accessible and less expensive than online storage, but still useful for backup data storage. A mechanical device is usually used to move media units from storage into a drive where the data can be read or written. Generally it has safety properties similar to on-line storage.

Several models of the 3851 were available. The smallest A1 holding 706 cartridges storing 35.3GB, while the largest A4 held 4,720 cartridges storing 236GB in a 20-foot (6.1 m) long unit. All of the units were also available in the "B models" which added a second controller for on-line backups, as well as offline storage.
