Patent number: 7293033Abstract: A computer system that allows for multiple users that each have access to shareable files. In one exemplary embodiment, each user has a user file tree that corresponds to the shareable file tree and initially contains links or pointers to selected shareable files. Each user also has a private file area to store files. If a user wishes to access a shareable file to perform an action that does not modify the shareable file, then the user file tree will point to the shareable file and allow the user to access the file. On the other hand, if the user wishes to access a shareable file and perform an operation that modifies the shareable file, the computer system will make a copy of the shareable file and place the copy in the user's private file area. Next, the computer system will modify the user's file tree such that the link that pointed to the shareable file now points to the copy of the shareable file that was placed in the user's private file area.Type: GrantFiled: October 21, 2003Date of Patent: November 6, 2007Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Stanislav Protassov, Serguei Beloussov

Patent number: 7246211Abstract: A system and method for providing online data backup for a computer system. In which the computer system includes an intermediate block data container. The computer system may utilize the intermediate block data container to manage data block release during the online data backup process. When the data storage driver receives a request to write a block into a data area that has already been copied by the backup procedure, then the required write is performed without limitations. If the incoming write request is directed to an area not yet backed-up, then the write process is suspended and the current state of the given data area is copied to the intermediate data storage container. When the copy procedure is completed, the system will allow the write procedure to be executed. Thus, the content of the data block at the moment the backup procedure commenced is stored in the intermediate block container. The content will be copied from the intermediate block data container by the backup procedure when required.Type: GrantFiled: July 22, 2003Date of Patent: July 17, 2007Assignee: Swsoft Holdings, Ltd.Inventors: Serguei Beloussov, Stanislav Protassov, Alexander Tormasov

Patent number: 7209973Abstract: The present invention is a system and method for distributed, highly scalable, wide area peer-to-peer network data storage. The functionally equivalent servers in the system are divided into groups. Each server maintains a dynamic list which is polled to determine the availability of the closest neighbor servers. Each server is switched between the groups of servers to optimize network connectivity parameters. Data and directory files are divided into a plurality of pieces which are stored on different servers. Files are uniformly and independently named, utilizing a tree with a common root, logical pathways, and unique file identifiers. When a server receives a client request for file system access, the plurality of file pieces are collected and sent to the client server from the neighbor servers simultaneously in order to optimize bandwidth. Servers with maximum throughput capacity are utilized for highest transmission speed and reduced processing time.Type: GrantFiled: July 30, 2001Date of Patent: April 24, 2007Assignee: SWSOFT Holdings, Ltd.Inventors: Alexander Tormasov, Sergei Beloussov, Stanislav Protassov

Patent number: 6961868Abstract: The disclosed invention stores files in a set of independent, functionally equal pieces. These pieces are placed on different servers of a distributed network to achieve a pre-determined level of fault tolerance. Terms of fault tolerance are defined in terms of amount of unavailable sites in the network allowing receipt and access to the data file. Maximal and minimal number of pieces available are variable method parameters. The minimal amount of data pieces k needed to restore a data file is defined. The size of each piece is approximately equal to 1/k of the original file size. The maximal amounts of pieces are defined during distribution operation and depend upon a requested fault tolerance level. Redundancy in data storage is minimized and varies dynamically by changing the total amount of pieces available. Significant increase in data transfer rate is possible because all file pieces could be transferred parallel and independently.Type: GrantFiled: July 31, 2001Date of Patent: November 1, 2005Assignee: SWsoft Holdings, Ltd.Inventors: Alexander Tormasov, Mikhail Khassine, Serguei Beloussov, Stanislav Protassov

Publication number: 20030041097Abstract: The present invention provides a highly scalable system for fault tolerant distributed data file storage over a set of functionally equal network servers linked through a local network with network servers and client computers. Data files are represented as a set of transactional records, each record is disassembled into redundant, functionally identical data pieces with original file reassembly dependent only upon the number of data file pieces and not on the presence or absence of any particular data file piece. Local algorithms generate unique data file identifiers upon file creation and disassembly. Changes to the data file storage system are ranked by creation time and stored as separate records with unique transaction identifiers in addition to unique data file identifiers. A transactional data file record is stored by disassembling the transactional file into pieces placed at the network servers. Low-level transactional files are collected to reassemble the data file contents.Type: ApplicationFiled: July 11, 2002Publication date: February 27, 2003Inventor: Alexander Tormasov
