System for delivering an event journal during a back-up session in a distributed file system is presented. The system includes an event intake module, a load balancer, a plurality of object creation modules, a journal manager, and a journal service module. Each object creation module of the plurality of object creation modules further includes an ingestor and a drainer. A related method is also presented. The system and method provide for reliable and time-ordered delivery of events in the event journal.

A data back-up system configured to back-up one or more data sets from one or more devices to a data back-up server by using a proxy pool is presented. The data back-up system includes a load-balancer configured to distribute the one or more data sets across the proxy pool. The load balancer includes a data receiver configured to receive types of files, number of files, and total size of each file in the one or more data sets; a load estimator configured to estimate a weighted average load of each data set based on the number of files, the total size of each file, a compressibility factor for each file type, and an encryption factor for each file type; and a load distributor configured to distribute the one or more data sets as a plurality of workloads across the proxy pool.

A system and a method for on-demand search of a large data-set is presented. The system includes a data indexer, an index writer, and an index reader. The data indexer is configured to index the data set. The index writer is configured to create a multi-level directory including a plurality of directories having one or more hash partitions. The index writer is further configured to generate a hash table for each directory and write data from the indexed data set into a corresponding hash partition of a directory. The index reader is configured to identify and query a hash partition in each directory based on a search term and a corresponding hash table for the directory. The index reader is further configured to retrieve one or more relevant records, and present the one or more relevant records to a user.

System and method for on-demand search of a large dataset

A system for estimating one or more data storage parameters and/or statistics in a data storage system is presented. The data storage system includes a plurality of storage containers. The system includes a snapshot module, a container stats aggregator, a synchronization module, a global stats aggregator, and storage stats estimator.
