摘要： A method, a system, an apparatus, and a computer readable medium for transmission of data across a network are disclosed. The method includes receiving a data stream, analyzing the received data stream to determine a starting location and an ending location of each zone within the received data stream, based on the starting and ending locations, generating a zone stamp identifying the zone, the zone stamp includes a sequence of contiguous characters representing at least a portion of data in the zone, wherein the order of characters in the zone stamp corresponds to the order of data in the zone, comparing the zone stamp with another zone stamp of another zone in any data stream received, determining whether the zone is substantially similar to another zone by detecting that the zone stamp is substantially similar to another zone stamp, delta-compressing zones within any data stream received that have been determined to have substantially similar zone stamps, thereby deduplicating zones having substantially similar zone stamps within any data stream received, and transmitting the deduplicated zones across the network from one storage location to another storage location.

摘要： A system, a method, and a computer program product for adaptive scheduled periodic caching are disclosed. A data stream is received. The data stream contains a plurality of versions of data arranged in a plurality of data clusters. Each data cluster includes an anchor version having a plurality of versions of data dependent on the anchor version. A size of each anchor version of each data cluster is determined. A number of versions of data dependent on each anchor version is also determined. For each anchor version, a ratio of the determined number of dependent versions of data to the determined size of each anchor is computed. At least one anchor version for storing in a memory location is selected based on the computed ratio.

摘要： A system, a method, and a computer program product for performing deduplication of data using a scalable deduplication grid are disclosed. A listing of a plurality of zone stamps is generated, where each zone stamp represents a zone in the plurality of zones in a data stream. The listing contains a logical arrangement of the plurality of zone stamps obtained from each storage location and being accessible by a plurality of servers. A first zone stamp in the listing is compared to a second zone stamp in the listing. The first and second zones are delta-compressed based on a determination that the first zone stamp is substantially similar to the second zone stamp. A server is selected to perform the comparison and delta-compression.

摘要： The present invention provides systems and methods for transferring a set of files. Metadata and stub files associated with the set of files are received at a destination fileserver, a location component in the destination fileserver is updated to maintain a list of repository nodes associated with each file in the set of files, and each stub file is replaced with the full content of the file associated with the stub file. The replacing includes receiving a client request for a specified file in the set of files and replacing the stub file associated with the specified file with a full content of the specified file if the full content of the specified file has not yet been transferred. Replacing the stub file associated with a requested file is a higher priority task than replacing a stub file associated with a non-requested file.
摘要翻译：本发明提供用于传送一组文件的系统和方法。与文件集相关联的元数据和存根文件在目标文件服务器处被接收，目的地文件服务器中的位置组件被更新以维护与该组文件中的每个文件相关联的存储库节点的列表，并且每个存根文件被替换为与存根文件关联的文件的完整内容。替换包括在文件集中接收到指定文件的客户端请求，如果指定文件的完整内容尚未传输，则用指定文件的完整内容替换与指定文件相关联的存根文件。替换与所请求的文件相关联的存根文件是更替优先级的任务，而不是替换与未请求的文件相关联的存根文件。
