Druva Assigned Five Patents

Dynamic resource allocation during data backup/restore
Druva Inc., Santa Clara, CA, has been assigned a patent (12299491) developed by Manley; Stephen, Livermore, CA, Srinivasan; Preethi, Sunnyvale, CA, Singh; Ritesh, Jamshedpur, India, and Potnis; Ajay, Pune, India, for “system and method for dynamic resource allocation during data backup/restore.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A resource allocation map generator generates a resource allocation map for a current data backup and/or restore based on a mathematical model, real-time operating data corresponding to operating states of one or more resources, and historical data corresponding to data back-up and restore of one or more historical datasets. A resource allocation recommender generates a recommendation for resource allocation for the current data backup and/or restore based on the resource allocation map and a threshold value corresponding to a particular resource. A resource allocator dynamically initiates a change in resource allocation based on the generated recommendation.”

The patent application was filed on 2021-12-15 (17/552191).

Data compaction
Druva Inc., Santa Clara, CA, has been assigned a patent (12158860) developed by Jain; Somesh, Pune, India, Singh; Rohit, Ghaziabad, India, Agarwal; Shubham, Kota, India, and Borate; Milind Vithal, Pune, India, for “data compaction systems and method.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A file system and a related method are presented. The file system includes a data storage including a plurality of data blocks; a merge index including a plurality of namespace entries, wherein the plurality of namespace entries include a plurality of blockmap entries and a plurality of local reference entries; a deduplication database including a plurality of deduplication indices and a plurality of global reference entries for a plurality of datasets; and an indexing system configured to generate the plurality of namespace entries and the plurality of global reference entries.”

The patent application was filed on 2023-01-11 (18/095825).

Data management system for transferring files between databases
Druva Inc., Santa Clara, CA, has been assigned a patent (12153496) developed by Gottipati; Srikiran, Vijayawada, India, Borate; Milind, Pune, India, and Chitaliya; Nishith, Amravati, India, for a “data management system for transferring files between databases.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data management system manages concurrent readers and writers for large file scans. The data management system may read a plurality of data chucks of the file starting from different offsets and generate a bounded number of read requests, which causes a data chuck identifiable by a data offset to be loaded into a data buffer. The system may queue the loaded data chucks for generating write requests to release the loaded data chunks. One or more write requests are generated responsive to one or more data chunks being associated with a consecutive order of data offsets being successfully loaded to data buffers. The system may write data chucks released from the buffer-rounded reading stage to the data storage in a checkpointed writing stage. The checkpointed writing stage creates a checkpoint based on the data offset of the data chucks that have been completely transferred to the data storage.”

The patent application was filed on 2023-05-19 (18/199877).

Event journal delivery
Druva Inc., Santa Clara, CA, has been assigned a patent (12147309) developed by Thakur; Pallavi, Jain; Somesh, Borate; Milind Vithal, and Nishal; Prahlad, Pune, India, for “system and method for event journal delivery.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on 2020-12-14 (17/120565).

Data back-up using proxy pool
Druva Inc., Santa Clara, CA, has been assigned a patent (12093137) developed by Potnis; Ajay, Borate; Milind Vithal, Jathar; Sudeep, Nishal; Prahlad, Jain; Somesh, and Thorat; Nishant, Pune, India, for “system and method for data back-up using a proxy pool.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “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.”

The patent application was filed on 2021-04-16 (17/232900).
