Abstract: Systems and methods for identifying data files that have a common characteristic are provided. A plurality of data files including one or more data files having a common characteristic are received. A potential rule is generated by selecting key terms from a list that satisfy a term evaluation metric, and the potential rule is evaluated using a rule evaluation metric. The potential rule is added to the rule set if the rule evaluation metric is satisfied. Based upon the potential rule being added to the rule set, data files covered by the potential rule are removed from the plurality of data files. The potential rule generation and evaluation steps are repeated until a stopping criterion is met. After the stopping criterion has been met, the rule set is used to identify other data files having the common characteristic.

Abstract: A mechanism is provided for establishment, optimization, and routing of remote transitive name space access. The illustrative mechanism adds a new protocol primitive to distributed file systems, which establishes a new multiplexed client connection between the client, the transitive server, and the destination server(s). The protocol allows establishment of remote mounts on a transitive file server. The protocol allows the client to request a “recipe” for a direct connection to the destination file server without intermediate nodes. The protocol allows the intermediate server to be established as a multiplexer that forwards requests/responses to/from destination servers without unmarshalling/remarshalling.

Abstract: A computer implemented method and system manages digital media files in a non-linear video editing system. A user may store digital media files in a user directory. If an instruction is received to move a first digital media file from the user directory to a shared directory having a location that is not directly accessible to the user, such move occurs, thereby preventing direct access by the user to the first digital media file. A link is generated in the user directory to the first digital media file, the link providing the user indirect access to the first digital media file located in the shared directory. If the link to the first digital media file is deleted from the user directory, the first digital media file is not deleted from the shared directory until the system subsequently receives an additional instruction to delete files corresponding with previously deleted links.

A local tree is constructed for each user by assigning local weights for the one or more software elements based on user visits to the one or more software elements. A group tree is constructed for each group to which the users belong by assigning group weights for the one or more software elements based on the user visits to the one or more software elements. The local tree and the group tree are stored for use in various applications.

Abstract: Sequential media reclamation is usually performed after portions of a sequential access volume's data are no longer needed and the unused portion of the volume exceeds a threshold. Improved sequential media reclamation is provided by using a sequential access disk volume (for example, a volume of a virtual tape library (VTL)) embodied as a sparse file. Reclamation of objects stored in the volume is accomplished by nulling out regions of the sparse file that contain the objects that are no longer needed. A replication method is also provided in which information about the objects stored in the sparse file (such as offset and length) is used during replication to enable the correct portions of a target volume (embodied as a sparse file) to be nulled out to match a source volume (also embodied as a sparse file).

Abstract: File system views are created for each application executed by a user, where this user-specific view comprises operating system files needed to run the application and file system changes made with this application for this user. Changes made to the file system during execution are allowed (in accordance with the user's permissions), but by default, those changes are not visible to other applications or to other users. Optionally, a user or administrator may specify that one or more file system views are to be accessible from other views. The view-specific isolation of file system changes applies also to system files and meta-data alterations that might be made to the operating system. In one alternative approach, file system views may be created for an application without regard to individual users, where that application's view is then used for all users who execute the application.

Abstract: An improved scalable object storage system allows multiple clusters to work together. Users working with a first cluster, or with a multi-cluster gateway, can ask for services and have the request or data transparently proxied to a second cluster. This gives transparent cross-cluster replication, as well as multi-cluster compute or storage farms based upon spot availability or various provisioning policies. Vendors providing a cloud storage “frontend” can provide multiple backends simultaneously. In one embodiment, a multi-cluster gateway can have a two, three, or higher-level ring that transparently matches an incoming request with the correct cluster. In the ring, a request is first mapped to an abstract “partition” based on a consistent hash function, and then one or more constrained mappings map the partition number to an actual resource. In another embodiment, the multi-cluster gateway is a dumb gateway, and the rings are located only at the cluster level.

Indexing includes metadata indexing a metadata part, conditionally content indexing a content part, and updating the linking structure. Content indexing is performed only if the content part does not match a content part already stored and indexed. Index entries each associate a key word or key value with corresponding metadata or content parts containing the key word or key value.

Abstract: A method and system for minimizing loss of critical digital data while such data is being written to a storage medium. The critical digital data is written to a digital storage medium in small blocks or segments. As each segment is transferred to the storage medium, the file allocation table is updated and the file is closed. By segmenting the files into smaller file segments, the amount of critical data lost as a result of a system failure or power loss is reduced. During playback, the file segments are dynamically assembled allowing playback of the digital data in a continuous manner.

Abstract: Disclosed are systems, methods, and devices for providing off-line indexing to client-based software development environments. For example, an integrated development environment (IDE) may be provided, and a request for indexing of source code available to the IDE caused to be transmitted to a remote indexing server. In response, an index of the source code created by the remote indexing server is received and stored at an accessible storage location. In response to detecting at least part of an identifier received by the IDE, the index is accessed and information associated with the identifier retrieved. The associated information can then be displayed via the IDE. Prior to transmitting the indexing request to the remote indexing server, a computing device executing the IDE may first determine whether an index for the source code is already available to the computing device, and only transmit the request if no available index is found.
