Hitachi Vantara Assigned Patent

Hitachi Vantara Corporation, Santa Clara, CA, has been assigned a patent (10,235,251) developed by Clark, Nathan W., Millbury, MA, Bryant, Alan G., East Walpole, MA, Bramante, Jr., Richard D., Methuen, MA, and Kostadinov, Alexander Vladimirov, Brighton, MA, for a “distributed disaster recovery file sync server system.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”Example implementations are directed to restoration of data not only from the servers, but also from the clients connected to the server. Algorithms are incorporated to identify content that was created or modified after the last backup. This algorithm also identifies and resolves changes in the mount points for shared folders, preventing information leakage. When the server recovers from a failure, it notifies the clients about the recovery on their next connection. Each client then determines the current state of its mount points and file paths and compares them with the server’s mount points and file paths. After the comparison, the client comprehends and indicates the mount point differences by renaming them and sends entire local data, all files, folders, mount points) to the server. The server reconciles the differences.”

The patent application was filed on December 17, 2013 (14/915,372).
