Embodiment Construction

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other arbitrarily if there is no conflict.

[0031] figure 1 This is a method for data synchronization of a distributed file system according to an embodiment of the present invention, and the method includes:

[0032] S10. Detect whether the file has changed,

[0033] S20. If it is detected that the file has changed, synchronize the changed file to other distributed file systems.

[0034] Among them, step S10 includes detecting whether there is a newly created file or detecting whether the original file is modified.

[0035] In this embodiment, the modification of the original file can be detected by obtaining the metadata attribute of the...

Abstract

The invention provides a data synchronization method of distributed file systems and the file systems. The data synchronization method comprises the following steps: detecting whether a file is changed or not; and if the file is detected changed, synchronizing the changed file to other distributed file systems. The data synchronization method can be deployed on distributed file systems, so that real-time synchronization or fixed-time synchronization of user data can be realized, the requirements of safety and timeliness of the user data can be met to the largest extend.

Description

Technical field [0001] The invention relates to the field of data synchronization, and is characterized by a method and file system for data synchronization of a distributed file system. Background technique [0002] At present, most users may have such a requirement, that is, in order to ensure the security of their data, they want to back up important data, and require that the data can be synchronized in real time, can be synchronized from one file system to other systems, and ensure that Synchronized past data can be accessed. Generally, in order to meet user needs, many file systems cannot achieve real-time performance; in addition, even if data synchronization can be achieved, it may happen that the synchronized data cannot be accessed. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a distributed file system data synchronization method and file system to ensure that data is synchronized between different file syst...
