Computer backupAn operation or procedure that copies data to an alternative location, so it can be recovered if deleted or becomes corrupted. Depending on how often the data changes, how valuable it is, and how long it takes to backup determines how often a backup is run. For example, a company with valuable information such as customer records that change frequently may backup their data every day or in some cases every few hours. Even more sensitive data such as bank records may be stored on drives using some form of RAID, which helps protect the data even if a drive fails.

Today, there are dozens of different ways to backup your information and mediums to keep your data. For example, CD-R, DVD-R, USB thumb drives, external drives, and in the cloud are some of the most popular places to backup your data.
