Abstract: Methods, systems, and devices for data management are described. Point-in-time data that includes one or more files may be generated from data management information stored at a data management system having multiple nodes. One or more sets of virtual partitions may be created for at least one file of the one or more files. One or more external file descriptors associated with respective locations of the at least one file and one or more sets of internal file descriptors associated with respective external file descriptors and locations of corresponding sets of virtual partitions may be generated in response to a request. One or more subsequent requests to read the at least one file may be routed to the nodes based on the one or more sets of internal file descriptors. Based on the routing, the respective portions of the one or more files may be output in parallel.

Abstract: Methods, systems, and devices for data management are described. A data management system may request a backup from a host environment, and the host environment may preload, in response to receiving the request, a library configured to intercept backup communication traffic at the host environment. The host environment may execute the backup procedure for backing up the host data store, and communicate, using the preloaded library, backup data resulting from the executed backup procedure between the host environment and the backup system. The backup data may be transmitted using a cryptographic security protocol that encrypts the backup data.

Abstract: Methods, systems, and devices for data management are described. A data management system may receive a request to generate backup data for a set of data files from the one or more databases. The data management system may then generate, in response to the request, a file including a set of partitions including respective groups of shard files that correspond to respective groups of data files from among the set of data files. In some examples, a respective group of shard files within a partition of the set of partitions may include a first shard file representative of metadata for the partition and one or more additional shard files representative of the respective group of data files for the partition. The data management system may then distribute the respective groups of shard files to a set of nodes within the distributed backup system.

Abstract: A method, apparatus and computer program product are provided to determine one or more probe point data objects and/or validate one or more probe point data objects for use with determination of traffic conditions. A determined probe point data object may be determined and/or updated with one or more probe point data objects which exclude any probe point data objects determined to correspond to an off-road location. A validated probe point data object may additionally or alternatively be determined using one or more first validation sequence check operations and using one or more second validation sequence check operations. The determined probe point data object and/or validated probe point data object may be used to determine one or more traffic conditions, and as a result, traffic condition determinations may be determined more accurately and efficiently.
