In information technology (IT), backup or backup of data or a backup process means backing up computer data that is already in the secondary storage to a file so that it can be used to restore the original after a data loss event. The grammatical form is back up (phrasal verb), and the noun and adjective – “backup”.

Backups have two different goals. The main goal is to recover data after a loss, be it by data deletion or corruption. Data loss is a common experience for computer users; A 2008 study found that 66% of respondents lost files on their home computer. The secondary goal of a backup is to restore data from an earlier time in accordance with a user-defined retention policy, usually configured in a backup application, to determine the duration of copies. Although archives are a simple form of disaster recovery and should be part of any disaster recovery plan, archiving itself should not be considered a complete disaster recovery plan. One of the reasons for this is that not all backup systems can restore a computer system or other complex configurations, such as a cluster of computers, an active directory server or a database server, simply by restoring data from the archive.


Since the backup system contains at least one copy of all the data that is considered to be worth saving, the storage requirements can be significant. Organizing this storage space and managing the backup process can be tricky. An IT storage model can be used to provide a storage structure. Today there are many different types of storage devices that are useful for archiving. There are also many different ways in which these devices can be located to ensure geographic abbreviation, data security and portability.

Before sending data to the repository, they are selected, retrieved and processed. To optimize the archiving procedure, many different methods have been developed. They include optimization for working with open files and real-time data sources, as well as compression, encryption, and de-duplication, among other things. Each backup scheme should include test runs that confirm the reliability of the archived data. It is important to recognize the limitations and human factors included in each backup scheme.
