Provided are techniques for organizing a temporary device group for collaborative computing. A list of functions for each of a plurality of devices are stored. A determination is made to form a device group including a receiver device from the plurality of devices, where the receiver device will perform one of the functions. An individual function usage score is generated. In response to the individual function usage score exceeding a device threshold, a request to form a device group is sent to the receiver device. In response to receiving an indication of acceptance to form the device group from the receiving device, the device group is formed for a temporary period, where functions and data are shared in the device group.

Organizing a temporary device group for collaborative computing

A backup method is provided for a file system for managing hierarchical storage including one or more storage media on a computer system including one or more computers. Each of the one or more storage media includes a data part which is separated from an index and on which updated information is appended and kept. Each of a plurality of pieces of data within the file system is managed to be migrated to at least any of the one or more storage media. The backup method includes backing up metadata of the plurality of pieces of data migrated within the file system; and backing up the index of each of the one or more storage media to which the plurality of pieces of data have been migrated, substantially at the same time point as the metadata.

Backup and restoration for storage system

A method and a system for event validation on a vehicle. The method includes detecting an event determined by the vehicle. The method can include requesting and receiving external event determination, from at least one external source within a first surrounding area, based on the event. The method also includes generating an internal event determination based on the event and validating a validated event based on the both the external and internal event determinations. The method includes requesting and receiving external drive plan, from the external source within a second surrounding area, based on the validated event. The method also includes generating an internal drive plan, validating a validated drive plan based on the internal and external drive plans, and implementing the validated drive plan.

Event validation using multiple sources

Identifying a set of message files associated with a user. The identified files are processed on a file-by-file basis according to a closeness relationship. Message files are returned responsive to a search request and displayed according to the closeness relationship.

User-based file search results

A method, executed by at least one processor, includes generating a snapshot for a plurality of data files, receiving an update request for a selected file of the plurality of data files, determining if the selected file is subject to a backup policy, updating the selected file without preserving the snapshot of the selected file if the selected file is not subject to the backup policy, and updating the selected file while preserving the snapshot of the selected file if the selected file is subject to the backup policy. A corresponding computer program product and computer system are also disclosed herein.

Policy driven data updates

A mechanism is provided in a data processing system for asynchronous replication in a hierarchical storage management integrated storage system. For a given file to be replicated from a primary storage system to a remote storage system, the primary storage system accesses the remote storage system to determine file existence and migration status at the remote storage system for the given file. Responsive to the primary storage system determining that the given file exists and has been migrated from first tier storage to second tier storage at the remote storage system, the primary storage system determines a first performance penalty for file recall and a second performance penalty for sending excess data from the primary storage system to the remote storage system. Responsive to the primary storage system determining that the first performance penalty is greater than the second performance penalty, the primary storage system sends whole file data for the given file to the remote storage system to replicate the given file at the remote storage system.

Improving performance of asynchronous replication in HSM integrated storage systems

A computer-implemented method is provided for ensuring a particular service level provided by multiple devices. The method includes maintaining, by a database, complementation parameters for a set of device groups. Each of the device groups includes at least two devices such that one of the two devices can complement at least one functionality of another one of the at least two devices in a same one of the device groups. The method further includes monitoring, by a processor operatively coupled to the database, the devices in the device groups to detect device malfunctions. The method also includes, responsive to a detection of a malfunctioning device from among the device groups, ensuring, by the processor, the particular service level by changing complementation parameters of a corresponding one of the devices paired with the malfunctioning device.

Ensured service level by mutual complementation of IoT devices

Provided are techniques for delegating cloud-side roles to devices. Network quality information is received for a network from one or more devices. It is determined that the network is unavailable in an area from which the network quality information was received. For a new device, a trajectory path of the new device is predicted. It is determined that the new device is about to enter the area based on the trajectory path. One or more software modules and data are identified. The one or more software modules and the data are sent to the new device, wherein the new device executes the one or more software modules to generate one or more insights from the data.

Delegating cloud-side roles to devices

A method for avoiding inode number conflict during metadata restoration at a restoration location is provided. The method includes receiving metadata for a first file including an inode containing an initial internal inode number and a directory entry containing an external inode number, determining an allocation status of the initial internal inode number at the restoration location, identifying an available internal inode number to be allocated to the first file, updating the initial internal inode number in the inode for the first file with the available internal inode number, registering the available internal inode number and the external inode number in an inode mapping table indicating correspondence between the available internal inode number and the external inode number, and restoring the inode based on the available internal inode number.

Avoiding inode number conflict during metadata restoration

An information processing apparatus, backup method, and program product that enable efficient differential backup. In one embodiment, an information processing apparatus for files stored in a storage device includes: a metadata management unit for managing metadata of files stored in the storage device; a map generation unit for generating a map which indicates whether metadata associated with an identification value uniquely identifying a file in the storage device is present or absent; and a backup management unit for scanning the metadata to detect files that have been created, modified, or deleted since the last backup, and storing at least a data block and the metadata for a detected file in a backup storage device as backup information in association with the identification value.
