Title: Dennis James Hahn: Innovator in Data Backup and Recovery Techniques
Introduction
Dennis James Hahn is a notable inventor based in Wichita, KS (US), recognized for his contributions to data backup and recovery technologies. With a total of 4 patents, Hahn has developed innovative solutions that enhance the efficiency and reliability of data management systems.
Latest Patents
Hahn's latest patents include a data backup technique for backing up data to an object storage service. This invention provides a system, method, and computer program product for block-based backing up of a storage device to an object storage service. The process involves generating a data object that encapsulates data from a data extent, which covers a block address range of the storage device. The data object is named with a base name representing a logical block address (LBA) of the data extent, appended with an identifier that deterministically identifies a recovery point associated with the data object. This named data object is then transmitted to the object storage service for backup. During the initial backup, the full storage device is copied, while subsequent incremental backups only include data extents that have changed.
Another significant patent by Hahn is a data recovery technique for recovering data from an object storage service. This system and method involve identifying an address space of a data set to be recovered and locating a set of data objects stored by an object-based system that corresponds to the address space and a selected recovery point. The identified data objects are retrieved and stored to a storage device at a block address determined by the retrieved data objects, effectively recreating the address space.
