Problems solved by technology

This method has the problem that all file servers receive data from the client at the same time, which not only puts a huge pressure on the client's network, but also has a high possibility of file errors
If there is a network transmission error in one of the uploading processes, the client will be requested to retransmit, which will inevitably cause network congestion on the client, and the data consistency in each file server is also difficult to maintain

Abstract

The invention discloses a data backup and updating method of a distributed file system, and aims at providing an improved data backup and updating method of the distributed file system to reduce a network transmission pressure of a client and decrease data consistence maintaining difficulty of mutually backed up file servers. The technical keys of the invention are that: the client initiates a file server file uploading request to a resolution server; the resolution server appoints a file server for the client and returns one effective storage path of the file server to the client; the client uploads the file to the file server according to the storage path; the file server receives and stores the file uploaded by the client, returns a message about successful operation to the resolution server, and transmits the file uploaded by the client to other file servers; the resolution server after receiving the message about the successful operation returns a combined code of the storage path of the file uploaded by the client and the file name to the client, notifies the user and the like.

Description

technical field [0001] The invention relates to a distributed file system, in particular to a data backup and update method of the distributed file system. Background technique [0002] With the development of cloud storage technology, a large number of user visits is a huge test for the data throughput and system concurrency of cloud servers. In order to ensure the security of file storage and prevent the loss of files stored by users due to cloud server failure, various file copy backup methods are adopted in the prior art. [0003] In an existing system with multiple file copy storage servers (hereinafter referred to as file servers), all file copies on the server are obtained from the client. That is to say, when uploading files to the data server, the client directly communicates with multiple file servers, and uploads the files to each file server to realize file backup. There is such problem in such method, all file servers all receive data from client simultaneousl...
