Difference between Backup and Computer data storage

Backup vs. Computer data storage

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. 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.
