Answer:
Backup storage devices retains current copies of data on hand, enabling backup in the event of hardware failure or data loss. Backup storage, unlike long-term, archive, or cold storage, must allow for the quick recovery and restoration of backup data. Backup storage devices are disk-based hardware appliances that include specialized software for encryption, interconnection, data processing, and compression. A remote backup appliance aids in the maintenance and recovery of company operations. As storage media, backup storage frequently employs both disk-to-disk (d2d) and magnetic tape systems.
The primary function of such devices is data storage and processing, which serve to improve efficiency and performance. This component comprises hard disks, USB drives, solid-state drives, and portable hard drives. There are additional storage options, such as cloud storage, AWS storage, and so on, but they are not the principal sources of storage devices. These are some of the new ways to save data online. Storage devices are an essential component of a computer system.
