Backup

In information technology, a backup, or the process of backing up, refers to the copying into an archive file of computer data so it may be used to restore the original after a data loss event.

Backup software

Backup software are computer programs used to perform backup; they create supplementary exact copies of files, databases or entire computers.

Computer data storage

Computer data storage, often called storage or memory, is a technology consisting of computer components and recording media that are used to retain digital data.

Data deduplication

In computing, data deduplication is a specialized data compression technique for eliminating duplicate copies of repeating data.

Disaster recovery

Disaster recovery (DR) involves a set of policies, tools and procedures to enable the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster.

Disk array

Typically a disk array provides increased availability, resiliency, and maintainability by using existing components (controllers, power supplies, fans, etc.), often up to the point where all single points of failure (SPOFs) are eliminated from the design.

Storage virtualization

In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" a host computer system, "Treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." A "storage system" is also known as a storage array, disk array, or filer.
