Abstract: Distributed network-based data backup, recovery and deletion methods and a distributed network system thereof are provided. The methods include respectively establishing peer-to-peer connections between a host storage server and a plurality of peer storage servers, dividing original data into a plurality of data segments, generating a plurality of data segment copies corresponding to the data segments according to a minimum survival rate and the number of peer storage servers. The methods also include transmitting the data segment copies to the peer storage servers, wherein the number of data segment copies for each of the data segments is equal to a redundancy, and the redundancy is smaller than the number of the peer storage servers, and the data segment copies distributed to any one of the peer storage servers correspond to a portion of all the data segments. Accordingly, the methods can effectively and safely backup the original data.

Abstract: A virtual file managing system including a file request managing unit, an information repository, a file namespace managing unit, and a file access managing unit is provided. The file request managing unit receives a file access request issued by a client, and returns a processing result of the file access request. The information repository stores a data structure of the virtual file managing system. The file namespace managing unit looks up address and path content of the file from the information repository according to the file access request. The file access managing unit performs an operation of accessing a file according to the address and path content of the file.

Abstract: A data file management and search method based on file attributes is disclosed. At least one data file, externally imported or generated by a user, is retrieved. Attributes of the data file are edited, a virtual catalog corresponding to the data file is generated, and a catalog tree is built according to the data file and the virtual catalog. The virtual catalog and the data file are displayed by a user interface. A search operation is performed based on a search command to locate at least one required virtual catalog or data file among multiple data files and virtual catalogs. A basic operation is implemented on the located virtual catalog or data file.

Abstract: A distributed audio visual (AV) system including a plurality of media servers, a media renderer, and a control point which are connected to each other via a peer-to-peer network is provided. Each of the media servers includes a content directory management unit (CDMU) and a query content information (QCI) module, wherein the CDMU includes a synchronizer module and a content information maintainer (CIM) module. The synchronizer module synchronizes content information of AV contents stored in all the media servers. The CIM module records the content information and establishes an integrated content directory list according to the content information. The QCI module queries the content information. The control point obtains the integrated content directory list from one of the media servers and queries the content information related to all the AV contents, so as to control the media renderer to play the AV contents.
