The present invention is a method of organizing and processing data in a distributed computing system. The invention is also implemented as a computer program on a computer medium and as a distributed computer system. Software modules can be configured as hardware. The method and system organizes select content which is important to an enterprise operating said distributed computing system. The select content is represented by one or more predetermined words, characters, images, data elements or data objects. The computing system has a plurality of select content data stores for respective ones of a plurality of enterprise designated categorical filters which include content-based filters, contextual filters and taxonomic classification filters, all operatively coupled over a communications network. A data input is processed through at least one activated categorical filter to obtain select content, and contextually associated select content and taxonomically associated select content as aggregated select content. The aggregated select content is stored in the corresponding select content data store. A data process from the group of data processes including a copy process, a data extract process, a data archive process, a data distribution process and a data destruction process is associated with the activated categorical filter and the method and system applies the associated data process to a further data input based upon a result of that further data being processed by the activated categorical filter utilizing the aggregated select content data.

A disaster recovery system and a method therefor, having: a function for receiving write requests from a host computer to write log information indicating the contents of a database process executed for a database buffer on a main site, database data updated on the database buffer and status information indicating the position of log information used for disaster recovery; a function for transferring the received write request for log information to a recovery site by a synchronous remote copy process; and a function for transferring the received write request for database data to the recovery site by an asynchronous remote copy process. While remote copy can be executed at a long distance without data loss, the deterioration of the performance of a database process on a main site can be suppressed.

The on-chip copy process is extended so that the data may be copied between two blocks that may be on different chips, different planes on the same chip, or the same plane of the same chip. More specifically, the methods described here provide a single data copying mechanism that allows data to be copied between any two locations in a memory system. An exemplary embodiment uses an EDO-type timing. According to another aspect, selected portions of the relocated data, such as chosen words in a transferred page, can be updated in the controller on the fly. In addition to transferring a data set directly from a read buffer of a source array to a write buffer of a destination array, the data set can concurrently be copied, if desired, into the controller where an error detection and correction operation can be performed on it.

A computer system implements hot mirroring for main system memory. That is, the computer system permits a user to hot plug a new memory board into the system and the system will respond by switching to a mirrored memory mode in which write cycles are performed to both memory boards (new and old). Once a new board is hot plugged into the system, the contents of the old board are copied over, in a background mode, to the new board so that both boards will have the same data. Because this background copying process may take a non-trivial amount of time and may detrimentally interfere with other system traffic, the system a user to exert control over the relative speed of the background copying so as to trade-off the time it takes to switch over to the mirroring mode versus the impact on on-going system behavior.

A storage device including a logical volume being a migration source of an application copies data stored in the logical volume being a migration source into a logical volume being a migration destination of the application. After such a copy process is started, the storage device stores the data written into the logical volume being a migration source as differential data without storing the data into the logical volume being a migration source. When the copy process is completed for the data stored in the logical volume being a migration source, a management computer starts copying of the differential data, and in a time interval after the copying of the data stored in the logical volume being a migration source is completed but before the copying of the differential data is completed, a computer being a migration destination of the application is turned ON. With such a logically-partitioned computer system, power consumption at the time of application migration can be reduced.

In one embodiment, a system includes a performance monitoring facility of a database adapted for measuring performance of the database regularly, a data protection manager for controlling a backup operation of the database on a storage subsystem, logic adapted for providing an interface between the performance monitoring facility of the database and the data protection manager, logic adapted for starting the backup operation while informing the performance monitoring facility about the starting of the backup operation, logic adapted for continuously evaluating performance of the database to determine when a predefined performance criterion is violated, and logic adapted for sending information from the performance monitoring facility to the data protection manager to cause compliance with the predefined performance criterion in response to the predefined performance criterion being violated.

A system and method for providing a substantially constant-time copy operation for file system objects managed by a network storage server begins by generating a new file based on metadata in a source file. The system then generates a snapshot of the source file or the logical volume in which the source file resides. The system then copies each of the indirect blocks of the source file to a corresponding location in the destination file. During the copy process, a modified set of file system operations can be executed on the destination metadata container. In response to a read request directed to a target block in the destination file, the system determines if target block has been copied. If the block has not been copied, the system provides a data segment from the corresponding data block in the snapshot. Write requests are processed by generating a new data block and adding a reference to the new data block to the target location in the destination metadata container. During the copy process, the system checks each block reference before copying to determine if the block reference has been modified by a write operation. If the block was modified, the system skips copying that particular block reference. The system provides additional operations to execute truncate and append operations during the copy process.

The invention provides systems and methods for continuous back up of data stored on a computer network. To this end the systems of the invention include a synchronization process that replicates selected source data files data stored on the network and to create a corresponding set of replicated data files, called the target data files, that are stored on a back up server. This synchronization process builds a baseline data structure of target data files. In parallel to this synchronization process, the system includes a dynamic replication process that includes a plurality of agents, each of which monitors a portion of the source data files to detect and capture, at the byte-level, changes to the source data files. Each agent may record the changes to a respective journal file, and as the dynamic replication process detects that the journal files contain data, the journal files are transferred or copied to the back up server so that the captured changes can be written to the appropriate ones of the target data files.

A method in a data processing system for automatically terminating or resuming backup copy sessions after an abnormal interrupt or reset notification occurrence during a backup copy process. A status indication is entered into activity tables associated with a plurality of storage subsystems and devices within a data processing system in response to initiation of a backup copy session. Status indications are then entered upon successful completion of a backup copy session within the data processing system. The indications within the activity tables are reviewed to determine the status of a backup copy session upon restarting a resource manager, abnormal termination of a backup copy program, or an operating system initial program load. If a backup copy session has been initiated but not completed, the backup copy session is then terminated. The indications within the activity tables are also reviewed to determine the status of a backup copy session if a reset notification is raised by a storage subsystem. The tracks extents which are active for a volume associated with a particular session identification are determined. A comparison is then made between the tracks extents which are active and the volume and extent information associated with a physical session identification. If a match exists between the tracks extents which are active and the volume and extent information associated with a physical session identification, the backup copy session resumes. If a match does not exist, the backup copy session is terminated.
