Purpose of data protection (data backup)

· Continuous data protection (CDP), also called continuous backup or real-time backup, refers to backup of computer data by automatically saving a copy of every change made to that data, essentially capturing every version of the data that the user saves.

· The key principles of data protection are to safeguard and make available data under all circumstances. The term data protection is used to describe both the operational backup of data and business continuity/disaster recovery (BC/DR)

· Storage technologies that can be used to protect data include a disk or tape backup that copies designated information to a disk-based storage array or a tape cartridge device so it can be safely stored. Mirroring can be used to create an exact replica of a website or files so they're available from more than one place. Storage snapshots can automatically generate a set of pointers to information stored on tape or disk, enabling faster data recovery, while continuous data protection (CDP) backs up all the data in an enterprise whenever a change is made.

· The purpose of personal data protection isn’t to just protect person’s data, but to protect the fundamental rights and freedoms of persons that are related to that data. Whilst protecting personal data it is possible to ensure that persons’ rights and freedoms aren’t being violated. Ex: incorrect processing of personal data, might bring about a situation where a person is overlooked for a job opportunity or, even worse, loses current job.

· Not complying with the personal data protection regulations can lead to even harsher situations, where it’s possible to extract all the money from a person’s bank account or even cause a life-threatening situation by manipulating health information.

· Data protection regulations are necessary for ensuring and fair and consumer friendly commerce and provision of services. Personal data protection regulations cause a situation ex: personal data can’t be sold freely which means that people have a greater control over who makes them offers and what kind of offers they make.
