Method for local backing-up of data

Abstract

A method for local backing-up of data comprises the steps that a terminal sends a backing-up request to a local backup entity; the local backup entity verifies an identity of the terminal and returns a response; the terminal transmits the data to the local backup entity; the local backup entity gathers the data; the local backup entity conducts duplicate checking of the data; the local backup entity classifies grades of the data; according to grading results, the local backup entity backs up the data with different grades in a storage module; the local backup entity establishes and saves mapping relations; redundancy operations are conducted to the backed-up data; and completeness and reliability of the data with the high grades are verified. The method comprises the steps that safety and reliability of the data can be ensured; the cost can be saved; utilization rates of data storage resources and processing resources can be increased; repeated backing-up of the data with repeated contents can be avoided; physical space and power consumption can be reduced; the integration degree can be increased; and reading, writing and erasing can be accelerated.

Description

technical field [0001] The present invention generally relates to the field of computer data security, and more specifically relates to a method for locally backing up data. Background technique [0002] With the rapid development of the information industry, a large amount of data has emerged, which includes both original data, intermediate data and result data, among which the original data and result data contain important information. However, from the perspective of the computer system, on the time axis, disasters are inevitable due to external factors and the computer system itself. The so-called computer system disaster means: the serious failure or paralysis of the computer system caused by man-made or natural factors, which makes the business function of the computer system stop or the service can try to drop below the threshold, or it is a sudden burst that lasts for a considerable period of time. event. Common disasters include, but are not limited to: system di...

In addition, due to the huge amount of data, it puts great pressure on processing resources, and the writing and storage of data takes up a large number of threads and causes a sharp increase in power consumption. At the same time, the increase in electronic equipment brings about a decrease in writing speed, resulting in vicious circle
