Problems solved by technology

[0003] Sometimes, users or business systems may need to update files to cloud storage. If the update is an additional file, since the modified content is written at the end of the file in a certain format, the modified part can be directly uploaded for file update; and If the updated file is a non-append file

Example Embodiment

[0026] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0027] Such as figure 1 As shown, it is a schematic flowchart of an embodiment of a fast file update method applied to cloud storage of the present invention. In this embodiment, the fast file update process includes:

[0028] Step 101: The client submits a file information query request of the file to be updated to the cloud storage server;

[0029] Step 102: The cloud storage server returns part or all of the file segment metadata of the file to be updated to the client according to the file information query request, and the file segment metadata includes the current segment metadata. The hash value of the fragment, the hash value pointers of the previous and next fragments of the current fragment, the fragment data address of the current fragment, and the data length of the current fragment;

[0030] Step 103: The client terminal d...

Abstract

The invention relates to a method and a system of fast file updating applied to cloud storage. The method of fast file updating applied to the cloud storage comprises steps as below: a client terminal submits an inquiry requirement of information of files needing to be updated to a cloud storage server; the cloud storage server returns file fragmentation metadata of the files needing to be updated according to the inquiry request of the information of the files; the client terminal compares the file fragmentation metadata; the client terminal determines the file fragmentation metadata for updating according to the data comparison result; the client terminal uploads the file fragmentation metadata and the fragmentation data to the cloud storage server; the cloud storage server updates the corresponding file fragmentation metadata of the files needing to be updated. The invention relates to the system of fast file updating applied to cloud storage. During the uploading and updating process of the files, inquiry and comparison are carried out at first to determine the file fragmentation which is changed, and therefore only the file fragmentation which is changed is uploaded, fast uploading and updating of the files is achieved, and occupation of system resources and network resources is low.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a fast file update method and system applied to cloud storage. Background technique [0002] Cloud storage is a cloud computing system with data storage and management as its core. Cloud storage provides users with high-speed and secure storage services based on cloud computing technology, which can meet the growing storage needs of users and provide high-security, High reliability, high availability, high compatibility and open storage services to provide open cloud storage capability support. [0003] Sometimes, users or business systems may need to update files to cloud storage. If the update is an additional file, since the modified content is written at the end of the file in a certain format, the modified part can be directly uploaded for file update; and If the updated file is a non-append file, the whole file will change when the file is modified, so the file mus...
