Embodiment Construction

[0053] The present invention will be further explained and described below in conjunction with the accompanying drawings and specific embodiments of the description. For the step numbers in the embodiment of the present invention, it is only set for the convenience of explanation and description, and there is no limitation on the order of the steps. The execution order of each step in the embodiment can be carried out according to the understanding of those skilled in the art Adaptive adjustment.

[0054] A data deduplication method based on a storage gateway, comprising the following steps:

[0055] The storage gateway calculates the digest of the file to be uploaded and sends the digest to the server, so that the server issues a permission verification challenge command or a file upload command;

[0056] The storage gateway generates a response array according to the authority verification challenge command of the server, so that the server can perform authority verification;...

Abstract

The invention discloses a storage gateway based data duplication eliminating method, system and device. The method comprises the steps of, by a storage gateway, calculating an abstract of a to-be-loaded file and sending the abstract to a server so as to enable the server to send out a permission validation challenge instruction or a file loading instruction; by the storage gateway, generating a response array based on the permission validation challenge instruction of the server to enable the server to perform permissions validation; by the storage gateway, loading the to-be-loaded file to theserver by combining with a confused file based on the file loading instruction of the server; by the server, receiving the abstract of the to-be-loaded file which is sent by the storage gateway; andby the server, performing repeated checking on the abstract of the to-be-loaded file to generate the file loading instruction or the permission validation challenge instruction. The system comprises the storage gateway and the server; the device comprises a memory and a processor. The storage gateway based data duplication eliminating method, system and device greatly reduce workload of users, have high security and can be widely applied to the technical field of cloud computing.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a data deduplication method, system and device based on a storage gateway. Background technique [0002] In recent years, with the rapid development of cloud computing technology, more and more users use cloud storage services to store and manage data, resulting in a large amount of redundant data. In order to save storage space and network bandwidth consumption, researchers have proposed data deduplication (deduplication) technology, also known as deduplication technology. With this technology, redundant files or finer-grained data in cloud storage are eliminated, and the cloud storage server only needs to keep a copy of the data. [0003] Data deduplication technology can be divided into: client-side data deduplication and server-side data deduplication according to the location where deduplication occurs. In the client-side data deduplication scheme, the user...
