A storage technology that combines multiple hard drives together to provide fault tolerance and better performance. Data is spread out across the drives, along with additional calculated data, so that data can be re-generated if part of the array fails. RAID protects you against data loss in the case of hardware failure. Unlike backup, RAID does not offer protection against file corruption or deletion, or data loss to malware, theft, or natural disaster.
BackupA copy of data, stored in a secondary location, which is used to restore data in the primary storage location that is corrupted or lost. Restoring involves copying data from the backup to the primary storage to replace the corrupted or lost files. Backing up is a storage strategy that allows you to recover from data loss.
MalwareA term derived from "malicious software," and that refers to all computer viruses, worms, Trojans, and spyware.
A system that acquires, stores, monitors, preserves, and provides access to its resources, run by an organization committed to providing long-term access to authenticated content to its users. A repository requires significant infrastructure to build and maintain.
