Druva Technologies Assigned Patent

Druva Technologies Pte. Ltd., Singapore, Singapore, has been assigned a patent (10,387,378) developed by Singhal, Nikhil, Borate, Milind, and Deshkar, Shekhar S., Pune, India, for “storage and retrieval of file-level changes on deduplication backup server.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”When a backup client sends a request to back up a file to a backup server, the file and an index, (e.g., checksum, hash, encryption, etc.) of the file are stored on the backup server in an efficient deduplication storage. If a backup client sends a request to back up a modified version of a file already stored on a backup server, the modified portion of the file is stored. In addition, an index of the modified portion is generated and stored along with the modified portions on the backup server. The indices can be used to reconstruct the file or modified version of the file when retrieved. The efficient deduplication storage method ensures that multiple copies of files or portions of files do not exist on the servers.”

The patent application was filed on July 2, 2015 (14/791,038).
