Appl. No.:

10/452795

Steven R. Kleiman - Los Altos CA, US
David Hitz - Los Altos CA, US
Norman Hutchinson - Richmond, CA

Assignee:

Network Appliance Inc. - Sunnyvale CA

International Classification:

G06F 12/00
G06F 17/30

US Classification:

707203, 707204

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. The information is read from the intermediate storage medium using normalized or implied block list and written to the destination file system according to the second storage block arrangement.

International Classification:

G06F 17/00

US Classification:

707203, 707204

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. Also in a preferred embodiment, shadow snapshots can be maintained, with a shadow snapshot including a set of member storage blocks that formed a consistent file system other than an active file system, with a set of selected member storage blocks removed from the consistent file system.

Abstract:

Methods, systems and apparatus for choosing image labels. In one aspect, a method includes receiving data specifying a first image, receiving text labels for the first image, receiving search results in response to a web search performed using at least some of the text labels as queries, ranking the text labels, at least in part, based on a number of resources referenced by the received search results, wherein at least some of the resources each include an image matching the first image, and selecting an image label for the image from the ranked text labels, the image label being selected based on the ranking.
