Abstract

The invention discloses an object storage data transmitting method and device. The method includes the steps of receiving a data upload instruction, and segmenting objects in object flow into a plurality of data segments, calculating the fingerprint value of each data segment, reflecting a mapping table between the fingerprint values and corresponding storage positions according to the fingerprint values, calling a fingerprint value database, judging whether fingerprint values exist in the fingerprint value database, if yes, establishing the backward referencing from the data segments corresponding to the fingerprint values to the objects, if not, uploading the data segments corresponding to the fingerprint values, and upgrading the fingerprint values to the fingerprint value database. By segmenting the objects and selectively uploading data according to fingerprint existence, by means of an object transmitting protocol oriented to repeated data deletion, the overall access throughput of a system is improved; the utilization rate of a storage device and network bandwidth of the object storage system is effectively increased, and the data transmitting efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of object storage and deduplication of stored data, in particular to a method and device for object storage data transmission. Background technique [0002] With the continuous improvement of the level of social informatization and the rapid development of Internet technology, all kinds of unstructured data, such as pictures, audio and video, text data, etc. are showing an explosive growth trend. While cloud storage services bring convenience to people , the data scale is also expanding rapidly, which puts forward higher requirements for the ability to store massive data. Studies have shown that up to 75% of the data is duplicated, and an important reason for the low utilization of storage resources is the large amount of duplication and redundancy in the data. [0003] The object storage system accesses the objects in it mainly through uploading, downloading, and deleting. When the uploading system...
