Problems solved by technology

In the case of poor network communication quality, the data backup storage operation from the service management node to each backup management node may not be successful, or it may be successful after repeated retransmissions, which makes the reliability of data backup storage poor, and more The situation of repeated retransmission will also lead to the slow processing speed of data backup storage, and excessive occupation of network bandwidth resources, and the data backup process may be transmitted in plain text, and the transmission security is poor

Abstract

The embodiment of the invention provides a data backup method and device, and relates to the field of the internet. The method comprises following steps of receiving and storing data packets; carrying out fountain coding to the data packets; and sending the coded data packets to backup management nodes. When data packets need to be backed up, the fountain coding is carried out on the data packets; the coded data packets can be transmitted reliably under a condition that a network environment is relatively poor; moreover, the fountain coding is realized in a software mode, the speed is relatively fast, and the timeliness of backup transmission of the data packets is ensured; and coded transmission rather than plaintext transmission is carried out on the data packets, equivalently, the data packets are encrypted, and the data transmission security is ensured.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of the Internet, and in particular to a data backup method and device. Background technique [0002] With the continuous development of Internet technology, various network applications are being introduced, which are increasingly affecting people's production and life, followed by a massive increase in the amount of data and a massive increase in the number of visits. For a network application, the corresponding data can be the data of the software program of the network application, the data for managing and maintaining the operation of the network application, or the user data generated when the majority of end users use the network application. Data, which often has important value, needs to be stored securely. At the same time, with the rapid growth of end users, the number of visits to the web application may be very high. [0003] For this reason, at present, a typical serv...
