Abstract

The invention discloses a data storage method, equipment and system and aims to overcome the defects of long consumed time and low efficiency of copy-on-write operation executed on a file in a Base storage by a container in the prior art. In some feasible embodiments of the invention, the data storage method includes starting to create a copy of the file in a first container storage unit when the circumstance that the file stored in a Base storage unit is opened by application in a first container by a writable mode is detected; when the circumstance that write operation is performed on the file by the application in the first container is detected, acquiring update data of the file, and establishing and storing a data item according to the update data; when the circumstance that the copy of the file is created is detected, acquiring the update data of the file from the data item, and synchronizing the update data of the file into the copy of the file.

Description

technical field [0001] The present invention relates to the technical field of computer and communication, in particular to a data storage method, device and equipment. Background technique [0002] Container virtualization is an operating system level, very fast and efficient virtualization technology. Its principle is to provide different system views for different running processes based on the operating system kernel. This isolation can be used to ensure authorized access to hardware resources, such as CPU (Central Processing Unit, central processing unit) and IO (Input Output, input and output) bandwidth, while ensuring security and efficiency. Each container has a file system environment that is only accessible to the processes and applications in the container. Due to the fast, lightweight and efficient container virtualization, containers are suitable for large-scale deployment. In scenarios such as the Internet and private clouds, some customized specific applica...
