Appl. No.:

10/104694

John K. Edwards - Sunnyvale CA, US

Assignee:

Network Appliance, Inc. - Sunnyvale CA

International Classification:

G06F 17/30

US Classification:

707201, 707204, 707202, 707200, 707100, 707 1

Abstract:

A file folding technique reduces the number of duplicate data blocks of a file consumed on a storage device of a file server configured to generate a persistent image of its active file system at a point in time. According to the file folding technique, if “old” data blocks of the file are over-written with “new” data and that new data is identical to the data of the persistent file image, the old data blocks are “freed” and the file is directed to refer to the persistent image for its data. The invention reduces disk space consumption in a file server configured to generate persistent images of its active file system and, in particular, reduces overall persistent image disk usage.

Abstract:

The present invention provides a system and method for dynamically populating a list of most used execution points in a graphical user interface of an operating system based upon the utilization behavior of a user. One embodiment provides for depicting a list of execution points to most used programs by determining a list of eligible programs, tracking the usage of the eligible programs in a usage list, taking into account chronological order of the activation of the programs and determining which programs in the usage list have the most usage. These programs then have execution points placed on a displayed most used list in the graphical user interface.

US Classification:

726 4, 726 1, 726 17

Abstract:

This invention is directed to provide a method for enabling an administrator to monitor and selectively limit the computer functions available to a user. The method is carried out on a personal computer by an administrator, and administrator decisions can be enforced on other personal computers in a local network. The invention enables an administrator to restrict a user's logon hours, logon duration, access to computer functions, and access to applications based on content rating. In addition, the administrator may temporarily restrict or extend normally allowed access privileges. The invention also allows for the monitoring, auditing, and reporting of a user's computer function usage to an administrator.

International Classification:

G06F 17/30

US Classification:

707 6, 707 4, 707 5, 707 3

Abstract:

A metadirectory namespace is provided for storing files and directories “hidden” from one or more user-accessible namespaces. The metadirectory namespace is a separate, parallel namespace that coexists with other user-accessible namespaces in a storage operating system. Files and directories may be identified as being stored in a metadirectory based on their location or based on their associated flags. The metadirectory namespace may be selectively exported only to clients, users and applications given special file access permissions.

US Classification:

707201, 707204, 707101

Abstract:

A method for reducing duplicate data of an active file system, where the data is stored on a storage device of a storage system, is disclosed. A persistent image of the active file system is generated at a first point in time. At a later time, a sequence of steps to compare the active file system with the persistent image is initiated. Then, if a block of data of the active file system is identical to the data in the persistent image, the active file system is directed to refer to the persistent image for data of the file. Alternatively, if the block of data of the active file system is not identical to the data in the persistent image, the active file system is directed to refer to the data of the active file system. A file folding command may be issued to start the comparison.

US Classification:

714 42, 714 4, 714 7, 714 26

Abstract:

A method for handling a fault in a storage system comprises maintaining data in a mass storage subsystem and providing access to the data on behalf of a client. The method further comprises detecting a fault in a volume of data stored in the mass storage subsystem, determining a severity of the fault, and selecting a course of action in response to the fault, based on the severity of the fault.
