Benefits of secondary storage

There are two main benefits to moving infrequently used data from primary storage to secondary storage: to free capacity on primary storage and to lower overall storage costs.

Secondary storage provides a lower-cost, higher-capacity storage tier than primary storage, although the data stored is not immediately accessible. This tradeoff is worthwhile in some cases, such as for a backup disk appliance. Such an appliance can store a vast amount of data, but getting access to it requires dedicated backup software. Similarly, optical discs and backup tapes must first be mounted before they can be read.

Data sets stored on secondary storage include backup data, test/development data, scientific data, reference data, archived data and other older operational data that no longer requires daily access. Organizations may still gain value from this data by running analytics against it, or it may need to be stored only to meet regulatory requirements.

Data is often archived for long-term preservation. Whether to meet regulatory compliance or maintain business transaction records, some businesses need to store data for years or indefinitely. Because this data isn't frequently accessed or changed, it is more cost-efficient to store it on high-capacity secondary storage.

Some businesses store archive data in a third tier, separate from the storage tier used for backup and accessed even less frequently. This is called cold storage, or sometimes tertiary storage, but it is important to note that secondary storage is a blanket term for all nonprimary storage.
