Data backup is the basis of disaster tolerance, which refers to the process of copying all or part of the data set from the hard disk or array of the application host to other storage media in order to prevent data loss caused by system operation errors or system failures. Traditional data backup mainly uses built-in or external tape drives for cold backup. However, this method can only prevent human errors such as operational errors, and its recovery time is also very long. With the continuous development of technology and the massive increase of data, many enterprises begin to adopt network backup. Network backup is generally realized by professional data storage management software combined with corresponding hardware and storage devices.
