A file protection scheme for fixed content in a distributed data archive uses computations that leverage permutation operators of a cyclic code. In an illustrative embodiment, an N+K coding technique is described for use to protect data that is being distributed in a redundant array of independent nodes (RAIN). The data itself may be of any type, and it may also include system metadata. According to the invention, the data to be distributed is encoded by a dispersal operation that uses a group of permutation ring operators. In a preferred embodiment, the dispersal operation is carried out using a matrix of the form [IN<sub2>—< / sub2>C] where IN is an n×n identity sub-matrix and C is a k×n sub-matrix of code blocks. The identity sub-matrix is used to preserve the data blocks intact. The sub-matrix C preferably comprises a set of permutation ring operators that are used to generate the code blocks. The operators are preferably superpositions that are selected from a group ring of a permutation group with base ring Z2.

The present invention is a method of organizing and processing data in a distributed computing system. The invention is also implemented as a computer program on a computer medium and as a distributed computer system. Software modules can be configured as hardware. The method and system organizes select content which is important to an enterprise operating said distributed computing system. The select content is represented by one or more predetermined words, characters, images, data elements or data objects. The computing system has a plurality of select content data stores for respective ones of a plurality of enterprise designated categorical filters which include content-based filters, contextual filters and taxonomic classification filters, all operatively coupled over a communications network.

An image retrieval system has a network server, at least one client terminal and a data archive of a multiuser file management system, spatially separated from server and client, of a file server. A reduced data stream is now transmitted between server and client and includes a header for transmitting address and meta information with an additional data field that includes an access key to the bulk data stored in the external data archive. This reduces the data volume to be transmitted during image retrieval, and thus reduces the network utilization in the transmission of the data stream occurring between server and client. As a result of this, the time period required to transfer the modified data stream between server and client terminal is correspondingly short.

In a virtual disk library device access of data stored in a tape can be conducted at a high speed with a high-speed archiving process from a disk to the tape in units of LUs maintained. The efficiency of update of the data stored in the tape can be improved. In this system, when the data stored in the tape is to be accessed with a high-speed archiving process in units of LUs from the disk to the tape maintained, a disk staging process is performed in the unit of a page that is smaller than the unit of an LU, and accordingly, high-speed access can be implemented. In addition, when an update process for the data (LU) stored in the tape is performed, the host can be responded by only staging an update target page of the LU, and a prior disk staging process is performed for the remaining pages of the LU in the background. Accordingly, when the data is re-stored in the tape, immediately storing the data in the tape can be performed without performing a staging process.

A file system is capable of reading and writing a large amount of stream data, such as digital video / audio data, in real time, and is also capable of efficiently dealing with a normal data file of a small size. In the file system, realtime stream data is recorded in a recording apparatus while dividing the data into data units, each data unit corresponding to a predetermined time interval and being composed of a series of blocks, so as to form a realtime data file. When the realtime data file is read in real time, the data stored in the series of blocks is read at one time. Whether the data can be recorded or read is determined in accordance with a schedule of a recording / reading process of other realtime data or non-realtime data. The data is recorded or read in accordance with the determination result.
