Abstract

The invention provides a data backup method. The data backup method comprises the following steps: S1, initiating a complete backup request; S2, traversing a file to be fully backuped, storing the path of the file object to be fully backuped, setting the archiving bit of the file object as an archived state, performing backup on the directory, the file information and the data block of the traversed file object, and keeping the backuped complete file object; S3, initiating an incremental backup request; S4, traversing all file objects, and judging whether the archiving bits are in the archived states or not, if so, neglecting the file objects and the subordinate file objects thereof; or otherwise, performing a step S5; and S5, storing the path of the file object that is to be subjected to the incremental backup in a local information file, and setting the archiving bit of the file object as an archived state, then performing backup on the directory, the file information and the data block of the traversed file object to the data center. According to the data backup method, the lookup process for changed files is simplified, and the incremental backup efficiency of cloud storage file objects is improved.

Description

technical field [0001] The invention relates to the field of cloud storage, in particular to a data backup method. Background technique [0002] With the rapid development of the cloud industry, cloud storage products have become the most basic products and services in cloud services. Taking the enterprise network disk as an example, it has become the most popular enterprise-level cloud storage application, and it is also the major IT giants competing to enter. industry. [0003] Usually what we call "cloud storage" refers to "cloud object storage", which is used to store unstructured data. All major cloud computing vendors have implemented this cloud computing infrastructure. It abstracts unstructured data into objects, that is, one object per file, and provides an interface for addition, deletion, modification and query (API) based on the HTTP protocol to realize the storage and operation of unstructured data. [0004] The existing software and hardware integration produ...
