Embodiment Construction

[0037] See figure 1 As shown, the data backup and restoration method of the present invention employs a system comprising a data encryption module 1, a data compression module 2, a data decryption module 3, a data decompression module 4, a message processing module 5, a data upload module 6 and a data download module 7; The data encryption module 1 encrypts data through a specific algorithm, and the description of the encryption algorithm is encapsulated in the message processing module 5 as meta information, and the encrypted data is output to the data compression module 2 . The data compression module 2 uses a specific compression algorithm to process the output of the data encryption module 1, and the compressed data is sent to the message processing module 5 as input, and the description of the compression algorithm is also sent to the message processing module 5 as meta information. The data decryption module 3 obtains the description of the encryption algorithm from the ...

Abstract

The invention relates to the technical field of cloud computing, in particular to a regular data backup and recovery method based on cloud storage. In the regular data backup and recovery method, a data compression module, a data decompression module, a data encryption module, a data decryption module, a message encapsulation module, a data uploading module and a data downloading module are involved; the method comprises the following steps of: performing operation such as encryption, compression, message processing, uploading, checking and the like on data during data backup; and performing operation such as downloading, message processing, checking, decompression, decryption and the like on the data during data recovery. By the method, the data backup and recovery speed of a cloud storage system can be increased, the data backup and recovery efficiency can be improved, and the data transmission security can be enhanced; and the method can be applied to data backup and recovery of the cloud storage system.

Description

technical field [0001] The invention relates to the technical field of cloud computing, and relates to a data timing backup and recovery method based on cloud storage. Background technique [0002] As the name suggests, data backup is a process of retaining data in a certain way so that it can be reused in case of system damage or other specific situations. Data recovery is to restore the data to the latest state in case of a system disaster to ensure the normal operation of the system. [0003] Traditional data backup and data recovery include the following strategies: [0004] Full backup: All data is backed up every time. For example, all data is backed up on one tape on Monday, all data is backed up there on another tape on Tuesday, and so on. The advantage of this backup strategy is that when a data loss disaster occurs, the lost data can be recovered with only one tape (that is, the backup tape the day before the disaster). However, it also has deficiencies. First,...
