The invention is a modular backup and retrieval system. The software modules making up the backup and retrieval system run independently, and can run either on the same computing devices or on different computing devices. The modular software system coordinates and performs backups of various computing devices communicating to the modules. Actions of modules on one of the computing devices acts as a system manager for a network backup regimen. A management component acts as a manager for the archival and restoration of the computing devices on the network. It manages and allocates library media usage, maintains backup scheduling and levels, and supervises or maintains the archives themselves through pruning or aging policies. The management component is not hard wired in its functionality, but may adapt to changing circumstances in these policies. A second software module acts as a manager for each particular library media.

A system and method for “on-the-fly” de-duplication of data before storing the data in a storage system is provided. A data de-duplication module illustratively cooperates with protocol servers and a file system of a storage operating system executing on the storage system to implement the novel de-duplication technique. The de-duplication module illustratively generates a block store, an index file and a hash table on storage space provided by the storage system. The hash table is utilized for tracking fingerprints and locations of blocks within the block store. The index file is utilized for storing directory information identifying the contents of data containers stored on the storage system, while the block store is utilized to store raw data blocks that comprise the data containers.

A method, information processing system, and computer program storage product for managing disk failures in a disk array. At least one disk in a first disk array is determined to have failed.

A recovery virtual machine acquires execution frequency information from a file, and converts a procedure, of which execution frequency is high in the execution frequency information acquired, to native code, and the time for starting the conversion is thereby reduced. Furthermore, by performing conversion at a timing at which a target procedure is invoked, load occurring due to the conversion is distributed, to prevent occurrence of failure in execution of an application caused by the load occurring due to the conversion.

A server management apparatus for lowering migration costs during scale-in/scale-out and workload consolidation of a cluster system(s) to thereby reduce power consumption is disclosed. The apparatus manages a physical server group which renders operative a virtual server group thereon and, when putting into practice a cluster system including a plurality of virtual servers placed in the physical server group, manages the layout state of virtual servers pursuant to the load state of the virtual server group. When executing scale-in, a virtual server operating on a physical server with the minimum number of operative virtual servers is specified as a shutdown target. When executing scale-out, a workload variation is predicted to control a scale-out destination of cluster system so that load variation-resembled cluster systems gather on the same physical server. The scale-in execution timing is delayed if the predicted load variation tends to rise and accelerated if it falls.

The invention provides tools and techniques for migration of user profiles in place on a computer. In one method, a first step provides a migration content storage partition to hold migration content such as user settings. This partition is provided by using a partition manipulation tool to obtain sufficient space on the computer. A second step saves migration content into the provided partition. A third step deploys an image into another partition on the computer, overwriting that partition. A fourth step then uses the migration tool to restore migration content from the migration content storage partition into the newly imaged partition, thereby customizing the new image with at least some of the former image's user settings. The migration content storage partition may then be deleted, or it may be retained and made available to the user as additional storage.

Provided are a system and method for supporting communication between application programs and the processing of messages by those programs. A table driven approach is used to select appropriate components of modular application programs to process received messages. The selection is carried out in dependence on associations between message types (e.g. request, inform, reply) and other characteristics of the message (e.g. whether the message is an expected reply (as identified by an identifier value). Also used in said selection are dynamic characteristics of the message or the system (e.g. possibly expiry of a timeout, or the state of an application). Rules combine these criteria and determine the conditions for invoking an application program component. Also provided is a mechanism for differentiating between reply messages which are received out of serial sequence but are still current and messages which are invalid.

A novel and useful apparatus for and method of software based phase locked loop (PLL). The software based PLL incorporates a reconfigurable calculation unit (RCU) that is optimized and programmed to sequentially perform all the atomic operations of a PLL or any other desired task in a time sharing manner. An application specific instruction-set processor (ASIP) incorporating the RCU includes an instruction set whose instructions are optimized to perform the atomic operations of a PLL. A multi-stage data stream based processor incorporates a parallel/pipelined architecture optimized to perform data stream processing efficiently. The multi-stage parallel/pipelined processor provides significantly higher processing speeds by combining multiple RCUs wherein input data samples are input in parallel to all RCUs while computation results from one RCU are used by adjacent downstream RCUs. A register file provides storage for historical values while local storage in each RCU provides storage for temporary results.

A system and method for multivolume file system backup without suspending activity of user application programs uses a file system snapshot of two and more partitions or volumes of the storage device, or two and more data storages, significantly increasing computer system availability and allows backing up two and more partitions of the storage device without interrupting computer services. Backup procedure is performed online, simultaneously creates snapshots of two and more partitions of the storage device or storage devices in the pre-selected point of time and copies data blocks from partitions into the backup storage device, optionally through the intermediate storage device. When a write command is directed to a data storage block identified for backup that has not yet been backed up, the identified data storage block is copied from the storage device to the intermediate storage device, the write command is executed on the identified data storage block from the storage device, and the data storage block is copied from the intermediate storage device to the backup storage device.

A technique is disclosed that allows different computers in a network to create an identifier that uniquely identifies the network. The technique allows the unique identifier to be consistently created over time, regardless of the particular make up of the computing devices in the network at any particular point time. In some implementation, a computer within the network hosts the identification creation tool. In order to create a unique identifier for the network, the tool identifies each network adapter used by the host computer. Using this information, the tool identifies a gateway device used by the network adapter or adapters, and then determines the physical network address of that gateway device. For example, if the network is an Ethernet network, the tool will determine the medial access control (MAC) address for the gateway device. The tool then creates a unique identifier for the network based upon the physical address. The unique network identifier can then be used to associate the billing a usage fee, such as a licensing fee, with the network rather than with an individual computer within the network. Alternately or additionally, the unique network identifier can be used to maintain and support the gateway device for the network.

A method of processing a document object model (DOM) tree having at least one tag located at a given node in the tree. The tag serves as a marker that initiates the invocation of a tag handler that, in turn, performs a simple macro substitution or a more complex algorithmic reorganization and manipulation of the tree. Upon encountering the tag, given information is passed to a method. In a first embodiment, the given information is a text representation of XML in the DOM tree at the given node and any child nodes of the given node. In an alternate embodiment, the given information is the given node of the DOM tree itself. The method generates an XML string, which is then parsed into a new DOM tree having a root node. The given node and any child nodes are then replaced by the new DOM tree, with the root node of the new DOM tree being positioned at the given node in the original DOM tree. The process may then be repeated for any additional tags.
