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).
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]
An example of primary storage. 15 GB PATA hard disk drive (HDD) from 1999. When connected to a computer it serves as secondary storage. 160 GB SDLT tape cartridge, an example of off-line storage. When used within a robotic tape library, it is classified as tertiary storage instead. Read/Write DVD drive with cradle for media extended
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.
To optimize storage costs, cold data can be stored on lower performing and less expensive storage media. [2] For example, solid state disks may be used for storing hot data, while cold data can be moved to hard drives , optical discs , tapes , or migrated to cloud storage .
Cloud storage is generally deployed in the following configurations: public cloud, private cloud, community cloud, or some combination of the three also known as hybrid cloud. [4] In order to be effective, the cloud storage needs to be agile, flexible, scalable, multi-tenancy, and secure. [5]
