CDP (Continuous Data Protection) is a revolutionary and significant breakthrough to the traditional data backup technology. The traditional data backup solution focuses on the periodic backup of data, so it is always accompanied by problems such as backup window, data consistency and impact on production system.

CDP provides users with a new way of data protection. System administrators don't need to pay attention to the data backup process (because CDP system will constantly monitor the changes of key data, so as to automatically protect data), and only need to simply select the time point to be restored after the disaster, so as to realize the rapid recovery of data.

Extended data:

CDP tools were originally sold by startups, trying to sell them to mature backup vendors. Although the original CDP startup had some products and intellectual property rights, it was not successful. For example, EMC acquired Kashya Company because of its replication function, and was shocked by the CDP performance of Kashya Company. CA company acquired XOsoft and transformed its CDP into ARC high availability server. After acquiring FilesX, IBM added CDP function to its Tivoli Storage Manager TSM (Tivoli Storage Manager) system. Symantec acquired Revivio's CDP assets to enhance its backup software.
