Secondary storage is non-volatile, long-term storage.

Why Komprise is the Easy, Fast, No Lock-In Path to the Cloud for file and object data.Secondary storage is needed to keep programs and data indefinitely. Transparent move technology solutions that use file-level tiering to accomplish this.

Transparent archiving is key to ensuring that data moved to secondary storage still appears to reside on the primary storage and continues to be accessed from the primary storage without any changes to users or applications. When data tiering and archiving cold data to secondary storage, it is important that the archiving / tiering solution does not disrupt users by requiring them to rewrite applications to find the data on the secondary storage. This keeps the data easily accessible in order to satisfy both business and compliance requirements. Furthermore, in moving data from more expensive primary storage to less expensive tiers of storage, knowns as cloud tiering, storage managers are able to save money. The growth of organizational unstructured data has prompted storage managers to move data to lower tiers of storage, increasingly cloud data storage, to reduce the impact on primary storage systems. In addition, to lessen the demand on primary storage, object storage devices may also be used for secondary storage. In an enterprise environment, the storage of secondary data can be in the form of a network-attached storage (NAS) box, storage-area network (SAN), or tape. This replication or data backup process, ensures there is a second copy of the data. Secondary storage typically tiers or archives inactive cold data and backs up primary storage through data replication or other data backup methods.

Data management software is used to find the right data to place on secondary storage and move data to secondary storage without user disruption.Use cases include: Cold data storage, Cold data tiering or data archiving, data backup and Disaster Recovery storage.Examples include: Amazon Simple Storage Service (S3), Amazon Glacier, Azure Blob, Google Cloud ColdLine Storage, and on-premises object stores such as IBM Cloud Object Storage.Object-based secondary storage is extremely popular today especially in the cloud. It can use file (Network Attached Storage NAS via NFS and SMB/CIFS protocols) or block-based storage-area-network (SAN) or object formats.It can either be hosted on-premises at data centers or in the cloud.It is typically orders of magnitude cheaper than primary storage – it is designed for more capacity storage than performance.It is typically designed for long-term storage – its non-volatile media such as solid state devices, optical or magnetic storage devices such as tape.For example, internal secondary storage devices include the hard disk drive, the tape disk drive, and compact disk drive. This can consist of items like the operating system, device drivers, applications, and user data.

These devices store almost all types of programs and applications. Secondary storage is for any amount of data, from a few megabytes to petabytes. Secondary storage devices are storage devices that operate alongside the computer’s primary storage, RAM, and cache memory.
