Abstract: A computer implemented method includes receiving indexing data for groupings of business resources, identifying a first grouping of business resources from the groupings of business resources in response to a user query based on the indexing data, and retrieving a first business resource model associated with the first grouping of business resources. The first business resource model defines relationships among the business resources in the first grouping and further defines relationships among the groupings of business resources with respect to the first grouping of business resources. The method also includes generating a second business resource model based on the first business resource model in response to user input, and providing access to a second grouping of business resources associated with the second business resource model.

Abstract: The invention provides a method and system for duplicating all or part of a file system while maintaining consistent copies of the file system. The file server maintains a set of snapshots, each indicating a set of storage blocks making up a consistent copy of the file system as it was at a known time. Each snapshot can be used for a purpose other than maintaining the coherency of the file system, such as duplicating or transferring a backup copy of the file system to a destination storage medium. In a preferred embodiment, the snapshots can be manipulated to identify sets of storage blocks in the file system for incremental backup or copying, or to provide a file system backup that is both complete and relatively inexpensive.

Abstract: The invention provides techniques for duplicating all or part of a file system while maintaining consistent copies of the file system. A preferred embodiment reads data from the source file system (mapped according to a first storage block arrangement) creates an image stream and writes this data onto the destination file system (in accordance with a second storage block arrangement). Thus, the invention allows an image transfer between file systems that have dissimilar characteristics. An intermediate storage medium can be used to store or transmit the data read from the source file system before writing the data to the destination file system. (For example, the intermediate storage medium can include a magnetic tape or other archival device, or a network.) Another aspect of the invention writes the data to the intermediate storage medium using a normalized or implied block list.
