Abstract

The invention discloses a data copying method for a distributed file system, and the method comprises the steps: receiving a copying request transmitted by a client, and determining a target data structure corresponding to the copying request; generating metadata of the target data structure, and associating the metadata of the target data structure with metadata of a source file in the distributed file system to obtain an association relationship; and modifying the source file according to a data modification instruction sent by the client, and executing copy-on-write operation on the targetdata structure in the client according to the association relationship. The data copying efficiency can be improved. The invention further discloses a data copying system of the distributed file system, electronic equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data copy method and system of a distributed file system, an electronic device and a storage medium. Background technique [0002] With the ever-increasing demand for data storage, the amount of file data managed by enterprises also increases. When the business needs to copy a large amount of data in the file system, the client needs to read the data from the server to the client, and then the client sends the data to the server for writing, during which various IO confirmations are performed (eg: lookup, etc.). This data copy method has a long IO path and low data copy efficiency. [0003] Therefore, how to improve data copy efficiency is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0004] The purpose of the present application is to provide a data copy method and system of a distributed file system, a...
