What isnear online

Discover the concept of near online storage, also known as nearline storage, and how it differs from instant access and offline storage methods.

When it comes to accessing data, there are different levels of availability. Instant access refers to data that can be accessed immediately, while offline storage refers to data that is not readily accessible.

Near online storage, also known as nearline storage, falls between these two extremes. It offers a compromise between instant access and offline storage. With near online storage, the data is not readily available, but it can be accessed relatively quickly compared to offline storage. The system needs some time to locate the appropriate cartridge or disk before retrieving the requested information.

Tape and disk libraries are commonly used for nearline storage because they offer a good balance between accessibility and cost-effectiveness. While near online storage may not provide immediate access, it still offers a faster retrieval time compared to offline options.

So, the next time you come across the term “near online,” you’ll have a better understanding of its role in storing and accessing data.
