Abstract: Provided are a method, system, and article of manufacture, wherein a data structure corresponding to a set of client nodes selected from a plurality of client nodes is generated. Objects from the selected set of client nodes are stored in the data structure. A determination is made that an object corresponding to a client node of the selected set of client nodes has to be stored. An additional determination is made as to whether the object has already been stored in the data structure by any client node of the selected set of client nodes. The object is stored in the data structure, in response to determining that the object has not already been stored in the data structure by any client node of the selected set of client nodes.

Abstract: Techniques are provided for allocating storage space to a storage pool. A request for storage space for the storage pool is received. A list of locations associated with the storage pool is obtained, wherein the locations are capable of spanning multiple file systems or multiple directories within a single file system. One or more allocation techniques are applied to select one or more locations at which storage space is to be allocated. The storage space is allocated at the selected one or more locations.

Abstract: Provided are a system, method, and article of manufacture wherein at least two primary storage pools are configured, wherein a first primary storage pool is configured to indicate a second primary storage pool as a next storage pool in a storage hierarchy that comprises the first primary storage pool and the second primary storage pool. The first primary storage pool of the storage hierarchy is copied to a copy storage pool, wherein the first primary storage pool and the copy storage pool are included as parameters of a single command. The second primary storage pool is copied to the copy storage pool, in response to determining that the second primary storage pool is the next storage pool for the first primary storage pool in the storage hierarchy.

Abstract: A method for generating file copies with minimal mounting and positioning of storage volumes involves receiving a request to generate file copies specifying file selection criteria, identifying matching files meeting the selection criteria, locating the matching files on their storage volumes, and copying the files to a copy set. Determination of file copying order is optimized by placing greater emphasis on relative storage locations of matching files than on the order in which their copies are requested. Once a storage volume is mounted, all files stored on that volume are matched against the pending requests including future requests and if found to be the subject of a request, are copied from the mounted volume in optimal position-sensitive order. Copying from secondary storage is deferred until all copying from primary storage is complete.

Abstract: Provided are a system, method, and program for grouping backup objects stored in backup storage. A backup group is created and a plurality of backup objects are added as members of the backup group in separate backup transactions. The backup objects added to the backup group are stored to backup storage.

Abstract: Any node in a multi-node processing system may be employed to route commands to a selected group of one or more nodes, and initiate local command execution if permitted by local security provisions. The system includes multiple application nodes interconnected by a network, and one or more administrator nodes each coupled to at least one application node. Each administrator node has assigned security credentials. The process starts when the administrator node transmits input to one of the application nodes (an “entry” node). The input includes a command and routing information specifying a list of desired application nodes (“destination” nodes) to execute the command. In response to this input, the entry node transmits messages to all destination nodes to (1) log-in to the destination nodes as the originating administrator node, and (2) request the destination nodes to execute the command.

Abstract: Disclosed is a server having a plurality of clients coupled to the server at client nodes, and coupled to a plurality of receivers. Events, which may range from a successful completion message to a major error alert, may be generated relating to the server or to the client nodes. A method is disclosed for dynamically selectively distributing the events to particular ones of the receivers, in response to a selective enabling/disabling of the events to each receiver. The method with respect to client nodes comprises: upon opening a session of a client node, the selectively enabled events/receivers relating to the client node are determined. Upon the selective enabling/disabling occurring during the session of the client node, the determined selectively enabled events/receivers relating to the client node are dynamically updated.

Abstract: A system and method for storing data in a network computing environment. The network includes a source server that will receive data to be stored from a client and target servers that have locally attached physical storage media. A server-to-server protocol is used to establish a communication connection between the source server and target server while programming allows the storage of the data from the source server on the physical storage at the target server, while also creating a virtual volume at the source server on which the data is also stored. From the perspective of the client, the data appears to be stored at the source server on locally attached storage media. The present invention eliminates the requirement for actual physical media locally attached to the source server.

Abstract: Disclosed are a method, embodiable in computer readable program code, and a system for providing server-to-server event logging. A server-to-server event message is generated including 1) an event identifier, 2) any text insert pertinent to the event message, and 3) a source trail indicating the origin and history of the event, the source trail comprising an identifier of any server forwarding the event, each identifier separated by a special character, so that the origin and any subsequently transmitting servers may be known. Further, the source trail of a received server-to-server event message is parsed to determine each identifier in the source trail, and the event message transmitted to a receiving server only if the receiving server identifier is absent from the parsed source trail, thus preventing any loops which might cause the event to be repeated.
