Problems solved by technology

[0005] The main purpose of the present invention is to provide a data deletion method and device, aiming at solving the main idea of ​​current data deduplication is to use the data source locality feature to improve deduplication performance, and the locality feature is not obvious in distributed storage. Unable to delete data effectively and reasonably, resulting in insufficient deletion of redundant data and occupying storage space

Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] The invention provides a data deletion method.

[0052] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the data deletion method of the present invention.

[0053] In one embodiment, the data deletion method includes:

[0054] Step S10, acquiring data to be processed;

[0055] In this embodiment, when there is data to be processed, the processed data is the data to be processed, for example, when the data needs to be deleted, the data to be deleted is the data to be processed; or, for another example, when the data needs to be deleted , the historical data and the current data to be deleted are pending data. refer to figure 2 , the way to obtain the data to be processed includes:

[0056] Step S11, determining the mode of data deletion;

[0057] Step S12, when the data dele...

Abstract

The invention discloses a data deleting method and device. The data deleting method includes the steps: acquiring data to be processed; determining objects which match each other in the data to be processed; comparing data corresponding to the objects which match each other, and determining repeated data between the objects which match each other; and deleting the determined repeated data. The invention also discloses a data deleting device. The data deleting method and device can effectively and reasonably delete data, and can improve the storage space.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data deletion method and device. Background technique [0002] With the continuous advancement of social digital network informatization, the amount of data managed by IT companies around the world has increased dramatically, and the current large-scale data centers have continuously improved the requirements for the management of complex data in terms of scalability, performance, and cost. In order to slow down the growth of enterprise storage capacity, traditional data deduplication storage management technologies and methods can no longer meet the service quality requirements of big data backup applications, and new software and hardware technology advancements bring opportunities for the improvement of big data management capabilities. [0003] Most of the deduplication systems currently on the market must rely on fingerprint-based metadata indexing algorithms in or...
