Abstract: The described embodiments distribute and synchronize objects in a network. More specifically, the described embodiments distribute copies of objects locally (i.e., store copies of objects in local address spaces). By storing a copy of a given object in a local address space, the object's methods may be executed locally, which can help to avoid excessive network traffic associated with remotely executing the object's methods. However, executing an object's methods locally can result in the state of the object (i.e., data associated with the object, etc.) becoming out of sync with other copies of the object in the network. To avoid issues associated with unsynchronized copies of the object in the network, the described embodiments use a policy that specifies conditions under which objects are to be synchronized.

Abstract: A system, method and computer program product for synchronizing data written to tape with improved data recovery. When writing data to tape, an index is kept in memory and updated to reflect change(s) to a file system mounted on tape. After a predetermined amount of data is written to a tape, a device may perform a sync operation, causing the index to be written into a data partition of the tape. If the sync operation is successful, the index in the index partition of the tape can be updated using a copy of the index in the data partition of the tape next time the tape is mounted. If the sync operation is not successful, the device may write the data to a different location on the same or another tape, update the index, and force another sync operation. This process can be repeated.

Abstract: A method and associated system for efficiently firing mapping and transform rules during a bidirectional synchronization of two or more systems. A processor loads a set of mapping and transform synchronization rules and a set of cross-reference tables. When an event message received from a source system identifies a revision to an element of the source system's data, the processor parses the message to identify the revised source-system data. The processor uses the cross-references to identify synchronization rules that are associated with the revised data element. If any of the identified rules requires an additional source-system data element or an extrinsic data element located at an external source, the processor retrieves those further identified data elements. The processor then looks up the synchronization procedure of the identified rules, packages it into a synchronization message, and sends the message to the target system.

The management system selects a second pair group allocated resources different from resources allocated to the first pair group as a candidate migration destination of the first asynchronous remote copy pair with reference to the resource management information.

Abstract: A server stores files and manages the synchronization of those files across client devices in accordance with user preferences that may be embodied in change management rules. A first version of a file has been designated to be synchronized across at least a first client and a second client. The first client accesses the first version of the file and creates a first modified version of the file, and the second client accesses the first version of the file and creates a second modified version of the file. When the first and second clients attempt to re-synchronize their respective modified versions of the file, the server determines a preferred version from among the available modified versions of the file according to change management rules. Then, the preferred version is stored by the server and is subsequently served for synchronization across the client devices.

Abstract: A method, system and computer-usable medium are disclosed for improved point-in-time copying of data within an asynchronous data mirroring environment. A first establish for a first point-in-time copying process is generated, followed by submission of a request to initiate an asynchronous data mirroring process associated with the first point-in-time copying process.

Otherwise, the point-in-time establish reservation is then used to generate an establish for the second point-in-time copying process, which is then initiated.
