The system further can include an application image update smoothness processor programmed to consolidate changes to adjacent image regions in an image of a shared application for transmission to the communicatively coupled application sharing clients in a single application image update interval. A shared application smoothness method can include the steps of detecting common shared image changes across multiple adjacent display regions of a shared application image and transmitting updates for the multiple adjacent display regions to communicatively coupled application sharing clients in a single image update interval.

Abstract: Methods and apparatus are described for a horizontally scalable high performance object storage architecture. Metadata are completely decoupled from object storage. Instead of file names, users are given a locator when the object is uploaded and committed. Users can store the locator along with their own metadata or embed it directly in the static content. Clients can choose which storage nodes to store data on based on dynamic measures of node performance. Since there is no coupling among storage servers, performance can scale horizontally by adding more nodes. The decoupling also allows the front end services and storage to scale independently. High service availability is achieved by object-level synchronous replication and having no single point of failure. Failed nodes are rebuilt using copies of data in other nodes without taking the cluster offline. In addition to the replication, the ability to add or remove nodes on-line reduces maintenance-related service downtime.

Abstract: This document describes tools capable of differentiating a superset of entities from which a user may receive current updates effective to provide current updates for only some of the entities of the superset. In one embodiment, for example, the tools enable a user of a mobile device to select a set of entities from which the user will automatically receive updates that are current, easily accessible, and visible at-a-glance. The tools may forgo providing current updates for entities that are not selected by the user, though the tools may provide these updates when explicitly requested by the user or at particular times or events.

Abstract: This invention involves tracking and backing all the information that a user generates on its computer devices (including embedded devices) in real time. The local user server records all user actions and gestures (via various means that include TV cameras). All of this information (user actions and saved files in a computer) is then sent to a remote server via the Internet. This remote server has a virtual map of all the embedded devices on a computer that the person uses. The remote server immediately starts to interpret the user's actions (including user gestures). In one implementation, the invention stores user actions that are related to data generation (e.g. actions that called some links where data is stored, or executed some programs that generated data). In another variant the remote server generates and downloads the same files that are downloaded on the local user computer devices.

Abstract: A first log reader publishes first messages to a plurality of queues. The messages comprise changes for transactions extracted from a log by the first log reader. In response to one of the queues becoming unavailable, a second log reader is launched to read and extract from the log, and to publish second messages comprising changes for transactions extracted from the log by the second log reader to the unavailable queue as a catch-up queue. In response to the catch-up queue becoming available and the second log reader reaching the end of the log, the publishing of the second messages for the catch-up queue is transferred from the second log reader to the first log reader.

Abstract: A transaction system that allows for analysis and administration at the global transaction participant level is disclosed.

Abstract: A selective restore technique for restoring file systems within computer systems provides on-demand access during the restore process, while preventing users from slowing the restore process by generating random accesses to files that have not yet been restored, early in the restore process. The restored files are grouped into multiple groups of files, which correspond to multiple phases of the restore process. On-demand requests may be locked out for some or all users during the first one or more phases of the restore, while they are permitted for the subsequent phases, ensuring that critical files needed by all users will be available before the backup process is interrupted by on-demand accesses. The groups are generally organized by elapsed time since last access or modification, and may be organized at restore time or during periodic back-up operations so that the files may be similarly organized in the backup media.

Abstract: Application Programming Interfaces (APIs) and UI modifications for existing applications are used to implement efficient methods for taking content offline with full synchronization, incremental synchronization, in the case of document libraries per-folder synchronization, and the like. The APIs provide support for synchronizing changes to attachments, the ability to download a document library's complete contents or only a list of the available documents, and read-only folder hierarchy replication in the case of document libraries. These abilities coupled with corresponding user interface features enable easier browsing and searching of large document library structures, making edits to those documents offline, being able to see an up-to-date version of those documents in a preview mode, and receiving reminders when offline edits remain on the local computer and need to be updated to a server.

A storage management server calculates selection conditions of candidates for a copy data storage volume and an update request storage volume based on a continuous data protection period to continuously protect a protection target volume and a disk capacity and an update access characteristic of the protection target volume to thereby select, according to the selection conditions, the candidates for the copy data and update request storage volumes. At occurrence of abnormality in data of the protection target volume, the continuous data protection system can restore data to a particular position (point of time) within the continuous data protection period.

Abstract: Performing a synchronization operation is disclosed. A first processing thread is used to copy a first file from a first data storage to a second data storage using a first connection. A second processing thread is used to copy a second file from the first data storage to the second data storage using a second connection. The first file is copied substantially concurrently with the copying of the second file. The synchronization operation results in first copied file and a second copied file in the second data storage. A real-time replication operation is performed. The first copied file and the second copied file are updated in an order determined at least in part by an order in which changes were made to the first file and the second file, respectively, as stored in the first data storage.

Abstract: Systems and methods for synchronization including the use of a global equivalency identification datum or set of datum. A universally unique identification datum may be associated with each independently created associated data set. In some embodiments, a synchronization server software element may be responsible for maintaining synchronization for a plurality of clients, including software elements or devices. A record believed to be new by the software elements may verify that the record is actually new. In some embodiments, verification of the record's newness involves assuming that the local ID is a global identification datum and comparing that datum to the all the sets of datum that the Sync-Server knows about. The synchronization server software element may use a table to hold information for all of the records known to that element. In some embodiments these records may have been deleted in the past.

Abstract: A target database is synchronized with a source database and the source database is replicated to the target database in a database replication system. The source database is on-line during the synchronization. The source database is located at a first node of the system, and the target database is located at a second node of the system. Changes in the source database are replicated to the target database by sending a replication stream from the first node to the second node. Successive blocks of data are sent from the first node to the target database to synchronize or resynchronize the target database with the source database. Each block of data includes one or more rows of data. The successively sent blocks of data are inserted into the replication stream at a point when the respective blocks of data are current or consistent in the source database, and the replication stream is posted to the target database. Synchronization or resynchronization thereby occurs simultaneously with replication.

Abstract: A handheld device includes a host database having first and second API associated therewith, a client database and a notification handler. The notification handler sends a request for notification of a change in the host database to the first API and receives the notification of the change in the host database after the change has occurred in the host database. The notification handler then requests contents of the host database from the second API and requests contents from the client database. These contents are then compared by the notification handler to identify the change in the host database. The notification handler then sends a command to update the client database based upon the change in the host database such that changes made in the host database of the handheld device may be continuously synchronized with the user's desktop computer via a wireless communication network.

In a second phase, the attributes that match patterns pre-specified in a configuration are used to determine which data to replicate and which modifications to make the devices. In a third phase, the data is replicated. In a preferred embodiment, the described techniques comprise an application that runs on a host device or is embedded in a logic or memory device. The described invention is designed to be transparent for system redundancy and error recovery processes such as error correction, re-transmission on links, and raid configuration.

Abstract: A conductor transmits a commit processing request to directors in response to a commit request received from an application. Upon receipt of a response to the commit processing request from any one of the directors, the conductor notifies the application of a successful commit. If there is a pending transaction due to a failure in a director, the conductor instructs the director to process the pending transaction upon recovery from the failure. If a failure occurs in the conductor during transmission of the commit processing request and the commit processing request is not received by any of the directors, the conductor inquires the director whether there is a pending transaction after recovery from the failure, and instructs the director to process the pending transaction based on a processing result of the pending transaction obtained from another director.

Jobs are distributed for concurrent execution by the associated processors.

Abstract: Various technologies and techniques are disclosed that improve synchronization of data between varying types of devices and/or services. A full participant receives a request from another participant to perform a synchronization operation. The synchronization engine determines whether the device or service is a full, partial, or simple participant. The device or service is a simple participant if it has a data store for synchronized data and no knowledge store. The device or service is a partial participant if it has a data store for synchronized data and a knowledge store, but does not understand the knowledge. The device or service is a full participant type if it has a data store for synchronized data and a knowledge store and understands the knowledge. The synchronization engine performs the synchronization operation with the device or service using a set of logic that is appropriate for the type of device or service.

Abstract: Tools and techniques for asynchronous database updates between client applications and search utilities are provided. These tools may receive indications of updates occurring within a workspace in which two or more users are collaborating. Updates to the collaborative workspace may be committed to a collaboration database maintained internally by a collaboration application. The tools may generate request to commit these updates to a search utility, so that the updates are searchable. The search utility maintains a search database that is decoupled from and operates independently of the collaboration database. The tools may increment a notification counter associated with the collaborative workspace, with the notification counter tracking how many requests to commit updates are pending. Finally, the tools may send the request to commit the update to the search database asynchronously with respect to the collaboration database.
