Problems solved by technology

Currently, Windows 2012 implements deduplication of data within a single disk on the New Technology File System (NTFS, New Technology File System), but this implementation method has the following defects: 1. Data deduplication can only be realized within a single disk, not Global data deduplication; 2. Does not support searching for duplicate data in massive data; 3. Searching for duplicate data will cause IO performance to decline

Abstract

Embodiments of the invention disclose a data deduplication method, a data deduplication device, electronic equipment and a computer readable storage medium. The data deduplication method comprises thesteps of: acquiring a to-be-processed data container; searching a data container of which the data similarity with the to-be-processed data container meets a preset condition from existing data containers, and taking the data container as a target data container; and comparing the to-be-processed data container with the target data container, confirming duplicated data, and deleting the duplicated data in a post-processing flow. According to the data deduplication method and the data deduplication device, mass data deduplication in the global range can be achieved, and the purpose of saving storage space is achieved on the premise that the user IO performance is not reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of data processing, and in particular to a data deduplication method, device, electronic device, and computer-readable storage medium that can be executed in a post-processing flow. Background technique [0002] With the development of data technology, users have higher and higher requirements for high-performance storage, especially in cloud computing block device storage, such as higher read and write times per second (IOPS) and lower latency (Latency) , Because of this, the cost of high-performance storage has also increased significantly, such as all-flash storage arrays, non-volatile memory host controller interface specification solid-state hard disk storage (NVME SSD, Non-Volatile Memory Express Solid State Disk) and so on. In this case, it becomes very meaningful if the space occupied by storage can be saved without reducing the performance of user input and output (IO, Input Ou...
