Backup classification

Backup can be divided into system backup and data backup.

1. System backup: refers to the loss of the system files of the user's operating system due to disk damage or damage, computer virus or human error deletion, and the computer operating system cannot be started normally. Therefore, system backup is used to store the operating system in advance for backup support after failure.

2. Data backup: refers to data packets stored by users, including files, databases and applications, for data recovery.

Backup function

The function of backup is for backup support and use.

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.
