Data plays an essential role in business today. Most, if not all, E-business applications are database driven, and data backup is a necessary element of managing data. Backup and recovery techniques have always been critical to any database, and as real-time databases are used more often, real-time online backup strategies become critical to optimize performance. In this paper, current backup methods are discussed and evaluated for response time and cost. A prototype device driver, RORIB (Real-time Online Remote Information Backup) is presented and discussed. An experiment is conducted comparing the performance, in terms of response time, of the prototype and several current backup strategies. RORIB provides an economic and efficient solution for real-time online remote backup. Significant improvement in response time is demonstrated using this prototype device driver when compared to other types of software-driven backup protocols. Another advantage of RORIB is that the cost is negligible when compared to other hardware solutions for backup, such as Storage Area Networks (SANs) and Private Backup Networks (PBNs). Additionally, this multi-layered device-driver uses TCP/IP (Telecommunications Protocol/Internet Protocol) which allows the driver to be a “drop in” filter between existing hardware layers and thus reduces the implementation overhead and improves portability. Linux is used as the operating system in this experiment because of its open source nature and its similarity to UNIX. This also increases the portability of this approach. The driver is transparent to both the user and the database management system. Other potential applications and future research directions for this technology are presented.
