Druva Assigned Three Patents

Storage tiering for backup data
Druva Inc., Santa Clara, CA, has been assigned a patent (11755416) developed by Borate, Milind, Jain, Somesh, Thakur, Pallavi, and Apte, Anand, Pune, India, for a “storage tiering for backup data.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A backup management system may include a data management server, a warm-tier data store, and a cold-tier data store. Snapshots may be captured from various client devices. A data block stored in the warm-tier data store may be referenced by multiple backup snapshots and/or referenced by one or more users. When a data block’s total reference count is equal to the cold reference count or equal to or less than a threshold total reference count, the data management server may determine that the data block is ready to be migrated to the cold-tier data store. The data management server may send the data block into a candidate queue. In the queue, data blocks with similar retention periods or similar expected restoration may be grouped as a unit. The unit may be transmitted to the cold-tier data store in a single write request.”

The patent application was filed on 2021-01-08 (17/145147).

Recovery point objective optimized file recovery
Druva Inc., Santa Clara, CA, has been assigned a patent (11755420) developed by Borate, Milind, Apte, Anand, and Thakur, Neeraj, Pune, India, for a “recovery point objective optimized file recovery.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system includes a data store and a data management server. The data store stores a plurality of backup snapshots that capture states of a device at different times. The data management server receives a request to restore the device that is potentially malware affected. The data management server retrieves a first backup snapshot of the device. The data management server determines that a first file stored in the first backup snapshot is malware affected. The data management server checks one or more corresponding versions of the first file captured in one or more previous backup snapshots to identify a clean version of the first file. The data management server determines that a second file stored in the first backup snapshot is clean. The data management server restores data in the device.”

The patent application was filed on 2020-11-18 (16/951579).

Dynamic file chunking system for data backup
Druva Inc., Sunnyvale, CA, has been assigned a patent (11734226) developed by Ramteke, Ashish, Chaudhary, Jagdish, Chandak, Kailash, and Jain, Somesh, Pune, India, for a “dynamic file chunking system for data backup.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system for dynamic file chunking is provided. The system includes a memory and a processor configured to access one or more files to be chunked for a data backup operation and to identify a type of the one or more files. The type of the file is based upon an extension of the respective file. The processor is configured to analyze storage data associated with each type of files corresponding to a plurality of chunking techniques. The processor is configured to associate each of files with a corresponding data chunk size and a chunking technique class based upon the analyzed storage data and to analyze data backup parameters in-real time during the data backup operation and to update at least one of the data chunk size and the chunking technique for each of the type of files based upon the data backup parameters.”

The patent application was filed on 2020-09-29 (17/035903).
