FILE UPLOADING METHOD IN CLOUD STORAGE, CLIENT, APPLICATION SERVER, AND CLOUD STORAGE SYSTEM

摘要

The present invention discloses a file uploading method, a client, and an application server in cloud storage, and a cloud storage system. The method includes: extracting an eigenvalue of a target file to be uploaded; submitting an upload request including the eigenvalue to an application server, so that the application server determines, according to the upload request, whether a client needs to upload the target file; receiving an execution instruction that is sent, according to a determining result, by the application server; and if the execution instruction is an upload instruction, uploading the target file to a file server according to the upload instruction. The present invention can optimize a file uploading process, thereby avoiding a waste of traffic, and improving uploading efficiency.
