A backup cell has a manager software agent responsible maintaining and initiating a backup regime for the network computing devices in the backup cell. The backups are directed to backup devices within the backup cell. Several backup cells can be defined. A manager software agent for a particular cell may be placed into contact with the manager software agent of another cell, by which information about the cells may be passed back and forth. Additionally, one of the software agents may be given administrative control over another software agent with which it is in communication.

A system and method for transferring data in a library storage system. The library storage system comprises a management server including a storage policy. A media agent is connected to the management server. A plurality of storage media and a data source are connected to the media agent. The data source is divided into at least a first and a second portion of data. The portions of data are transferred from the data source to a first and second primary storage medium using a first and a second data stream respectively. The media agent then causes the first and second portion of data to be transferred from the first and second storage medium to a third auxiliary storage medium using a third combined data stream. Auxiliary copying is performed in chunks and multiple streams are copied in parallel.

An incrementally-scalable database system and method. The system architecture enables database servers to be scaled by adding resources, such as additional servers, without requiring that the system be taken offline. Such scaling includes both adding one or more computer servers to a given server cluster, which enables an increase in database read transaction throughput, and adding one or more server clusters to the system configuration, which provides for increased read and write transaction throughput. The system also provides for load balancing read transactions across each server cluster, and load balancing write transactions across a plurality of server clusters. The system architecture includes an application server layer including one or more computers on which an application program(s) is running, a database server layer comprising two or more server clusters that each include two or more computer servers with replicated data, and an intermediate "virtual transaction" layer that includes at least two computers that facilitate database transactions with one or more databases operating in the database server layer. Data in the database(s) are evenly distributed across the server clusters in fragmented mutually exclusive subsets of data based on a hashing function. An application program interface is provided so as to enable application programs to perform a full range of database transactions without regard for where data is stored, or what database(s) is operating in the database server layer.

A system is disclosed in which a data processing device is completely synchronized with a messaging service. One embodiment of the system comprises a wireless data processing device; a messaging service to maintain messages and other information on behalf of a user; and synchronization logic for maintaining synchronization of the messages and other information between the wireless device and the messaging service.

A system and a method are disclosed for synchronizing folders between one or more layers of folders. It includes selecting layers to link together, comparing folders in the selected layers using an immutable identifier, parsing the folders of each of the selected layers into fields, comparing the fields of parsed folders of the selected layers, and determining whether to synchronize the folders of the selected layers based on conflict rules triggered in response to the comparison of the fields of the parsed folders. Also disclosed is a system and method of merging two or more folders in a network into a single folder. It includes comparing entries between folders to identify duplicate entries, grouping the identified duplicate entries in each folder, generating a matrix from the duplicates grouping and assigning each matrix entry a value, and matching the matrix entries based on the assigned values to determine an extent to merge an identified duplicate entry.

An extensible protocol to replicate, integrate and synchronize distributed information is described which may be implemented in a computer system. A system and method for replicating, integrating and synchronizing distributed information is also described.

A method and apparatus for remotely synchronizing a mobile terminal to a target computer is disclosed. A user's operation of the mobile terminal is monitored and a computer program is executed for adapting ordering and filtering synchronization rules in response to the user's operation of the mobile terminal to generate a modified set of synchronization rules. Synchronization data is exchanged between the target computer and the mobile terminal using the modified set of synchronization rules.

Transaction ping-pong is selectively prevented in a bidirectional database replication system. The system has a plurality of nodes connected via communication media in a topology. Each node includes a database and a transaction transmitter or collector which sends transactions posted to the database to a database at one or more other nodes for replication in the databases of the one or more other nodes. All transactions to be posted to databases in remote nodes that were sent by a local node are detected, and the database at the local node is inhibited from posting selective transactions which were detected as being originally sent by the local node.

Techniques associated with intelligent device connection for wireless media ecosystem are described, including receiving, by a media device, a first control signal from another media device implementing a connection awareness device, the first control signal configured to cause the media device to access data associated with playing a media content being played by the other media device, obtaining marker data from the other media device, the marker data representing a marker associated with the media content, retrieving content data from using the marker data, the content data configured to play the media content starting at a point indicated by the marker data, and sending a second control signal to the other media device, the second control signal configured to indicate a completion of synchronization with the other media device.

Objects in a master database and objects in a replicated database are synchronized using identifiers and version stamps of the objects. Each object has a unique identifier and a version stamp that is incremented when the object is updated at the master database. A synchronization server uses the identifiers and version stamps of objects to perform out-of-date detection and conflict detection. The synchronization server resolves update conflicts according to rules.

Various embodiments of the present invention are directed to a storage platform comprising a database engine, a data store, an application programming interface. The data store is implemented on the database engine for storing data therein, and the data store implements a data model that supports the organization, searching, sharing, synchronization, and security of data stored in the data store. Specific types of data are described in schemas.

A distributed database system has multiple compute nodes each running an instance of a database management system (DBMS) program that accesses database records in a local buffer cache. Records are persistently stored in distributed flash memory on multiple storage nodes. A Sharing Data Fabric (SDF) is a middleware layer between the DBMS programs and the storage nodes and has API functions called by the DBMS programs when a requested record is not present in the local buffer cache. The SDF fetches the requested record from flash memory and loads a copy into the local buffer cache. The SDF has threads on a home storage node that locate database records using a node map. A global cache directory locks and pins records to local buffer caches for updating by a node's DBMS program. DBMS operations are grouped into transactions that are committed or aborted together as a unit.

A system and method are directed towards providing a database replication technique using interception in memory of the transaction change data records. The invention employs Input/Output instrumentation to capture and split out the in memory transaction change journal records. Captured memory blocks are sent to a parser, which concatenates the records into a single record, and creates a redo/undo vector that can be converted to original DML/DDL statements. Source level transformations can be applied to the vectors, which are then sent to a post agent on the same or a different computing device. The post agents may perform destination level transformations, and generate DML/DDL statements to be executed by the corresponding destination RDBMS instance. Post agents may also perform conflict detection and resolution during DML/DDL statement executions. Transaction consistency is supported by performing commits/rollback on the destination after receiving the redo/undo vector representing a commit/rollback on the source.
