Backup storage refers to a storage device, medium or facility that is used for storing copies and instances of backup data. Backup storage enables the maintenance, management, retrieval and restoration of backup data for any individual, application, computer, server or any computing device.
Techopedia Explains Backup Storage
Backup storage is primarily an additional storage device used for keeping backup data. Typically, it is external to the system, server or device for which the backup data is created, such as a local/remote storage server. The backup storage itself can be a hard disk drive, tape drive, compact disk drive or any mass storage medium installed within a computer or storage server. In enterprise IT environments, the backup storage medium/technology used can be RAID, a storage area network or a network-attached storage system. Backup software or a backup manager is used to create, store, manage and retrieve backup data to and from the backed up application/device and the backup storage location.
