Problems solved by technology

[0005] The above protection measures have a great effect on improving data security, but on the one hand, it requires a lot of investment, on the other hand, the effect obtained is not enough to meet people's requirements for data security and reliability, and based on hardware redundancy The remaining methods have poor scalability, and it is often troublesome to add and delete new data servers

Embodiment Construction

[0045] The preferred embodiment of the present invention is described in more detail below with reference to the accompanying drawings of the present invention.

[0046] The network online backup system is generally divided into two parts: the client and the server, and the server can generally be divided into a name server and a data server group. Two parts of the present invention: data service virtualization can be used on the server side; data block redundancy can be used on the client side.

[0047] Figure 4 It is a structural diagram of data service virtualization applied on the server side. As shown in the figure, the data service pool is a virtual storage pool that can continuously add new data services, has good scalability, and is composed of multiple data services. Different data services can be located on the same machine or distributed across on multiple machines.

[0048] 1. Combine multiple data services into a data service pool. Register data services, and...

Abstract

This invention provides an on-line backup method based on data unblock redundancy and virtual storage, which divides a message to fragments to realize data unblock redundancy and virtual data service to get high data safety, reliability to extend the system with cheap hardware.

Description

technical field [0001] The invention belongs to the technical field of network communication, and specifically relates to an online network backup method, in particular to an online backup method based on data block redundancy and virtualized storage. Background technique [0002] Network online backup is a kind of data backup based on the network, that is to say, the user backs up the data to the remote data server through the network instead of the local hard disk. Through the effective management and protection of the remote data server, the maximum Protect user data to a certain extent, so that in the case of user data loss, data can be easily restored, and data security and disaster recovery capabilities can be improved. [0003] figure 1 It is a basic network online backup structure diagram. As shown in the figure, usually the network online backup method includes two services with different purposes: name service and data service. The name service is a service that...
