Abstract

The embodiment of the invention provides a data backup system and method, relates to the technical field of data storage, and can reduce loss caused by data loss. The system comprises a production server, a local storage server and a remote distributed file system, the remote distributed file system comprises a remote disaster recovery server and a plurality of remote storage servers, the remote disaster recovery server is a management node of the remote distributed file system, and the remote storage servers are data nodes of the remote distributed file system; the production server is used for generating to-be-backed-up data and sending the to-be-backed-up data to the local storage server; the local storage server is used for storing the to-be-backed-up data sent by the production serverand sending the to-be-backed-up data to the remote disaster recovery server; and the remote disaster recovery server is used for receiving the to-be-backed-up data and storing the to-be-backed-up data to each remote storage server in a distributed storage mode.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a data backup system and method. Background technique [0002] Data is both a resource and a wealth for people. Data has economic value, industrial value and scientific value. Correct and reasonable data mining and analysis can bring high value returns to the enterprise, so the effective storage of data is particularly important. Currently, data is typically stored on a computer's local disk. [0003] At present, in order to prevent data loss, data can be backed up through disk arrays. However, this backup method is difficult to cope with large-scale data loss, and if hardware damage occurs, data may not be recoverable, resulting in low data security. Difference. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a data backup system and method to improve the security of stored data. The specific technical scheme is...
