Druva Assigned Two Patents

Index based smart folder scan for cloud-computing provider network
Druva Inc., Sunnyvale, CA, has been assigned a patent (11,221,919) developed by Jacob, Rono Abraham, Pune, India, for “index based smart folder scan system and method for cloud-computing provider network.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A system and method for an index-based smart scan for a cloud-computing provider network is provided. The system includes a memory having computer-readable instructions stored therein and a snapshot repository configured to store a plurality of snapshots of a plurality of block storage volumes. Each of the plurality of block storage volumes is configured to perform volume based block storage operations for the cloud-computing provider network. The system further includes a processor communicatively coupled to the snapshot repository. The processor is configured to access contents of each of the plurality of snapshots. Each of the plurality of snapshots includes a point-in-time capture of the respective block storage volume. In addition, the processor is configured to perform a full scan of each of the plurality of snapshots to identify one or more files of the respective block storage volume. The processor is further configured to generate a folder index table for each of the files based upon the scan. The folder index table includes a listing of the file path and an associated modification time for each of the files. Furthermore, the processor is configured to update the folder index table over a pre-determined period of time and locate a file in the plurality of block storage volumes based on the folder index table.”

The patent application was filed on July 27, 2018 (16/047,213).

Data de-duplication among untrusted entities
Druva Inc., Sunnyvale, CA, has been assigned a patent (11,218,296) developed by Gottipati, Srikiran, and Borate, Milind, Sunnyvale, CA, for a “data de-duplication among untrusted entities.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A data storage system allows data to be encrypted and de-duplicated at the same system. By way of example, a server of the data storage system may request a client device which intends to upload a data block to transmit a first fingerprint of the data block to the server. The first fingerprint may be derived from the plaintext of the data block. The server may apply a one-way function to the first fingerprint to generate an encryption key and transmit the encryption key to the client device. The client device uses the encryption key to encrypt the data block and generates a second fingerprint which is derived from the ciphertext of the data block. The server uses both the first fingerprint and the second fingerprint to verify the data block and the legitimacy of the client attempting to upload the data block.”

The patent application was filed on July 8, 2019 (16/505,269).
