Position Summary: A Backup Appliance Composed of High-capacity Disk Drives
2001Co-Authors: K. Keeton, E. AndersonAbstract:Disk drives are now available with capacity and price per capacity comparable to nearline tape systems. Because disks have superior performance, density and maintainability characteristics, it seems likely that they will soon overtake tapes as the Backup medium of choice. In this position summary, we outline the potential advantages of a Backup system composed of high-capacity disk drives and describe what implications such a system would have for Backup Software. In the past, magnetic tape had higher capacity and lower price/GB than magnetic disk; however, technology trends are reversing this relationship. Tape’s capacity lead over magnetic disks has shrunk over the last 15 years, and disk capacity is now on par with tape capacity. Furthermore, disk media price is within a factor of 3X of tape media price, and disks cost less per GB than tapes, once the tape drive and the tapes supported by the enclosure are taken into account. Given these trends, it is time to rethink tape’s role as the Backup medium of choice. Disks confer tremendous hardware-related benefits for a Backup system:

An Object-Oriented Approach for High Availability of Applications Integration
2015Co-Authors: Jameela Al-jaroodi, Nader MohamedAbstract:The integration of networked applications, especially those requiring continuous access to shared information resources and databases, may be effected by scheduled unavailability of one or more of these applications. The scheduled unavailability usually occurs due to a number of reasons including application or data Backup, Software or hardware maintenance for the application’s platform, executing periodic processes such as file reorganization or end-of-period processes, application maintenance, or application migration. This paper provides an object-oriented framework to increase the availability of integrated applications without fully replicating the application environment such as the application platforms, programs, and data. The proposed framework can be used to maintain the integration of networked applications during scheduled unavailability of one of the applications. In addition, the proposed framework enables highly available applications integrations while maintaining data and state consistency of the applications. This framework provides a cost-effective solution for increasing availability of networked applications integration

© 2008 Science Publications A Middleware Service for Increasing Applications Integration Availability
2010Co-Authors: Nader Mohamed, Jameela Al-jaroodiAbstract:Abstract: Middleware has become an integral part of many distributed applications offering effective integration and interoperability solutions. In some situations a problem may occur where the integration of distributed information applications may be affected by scheduled unavailability of one or more of these applications. The scheduled unavailability occurs due to several reasons including application or data Backup, Software or hardware maintenance for the application’s platform, executing periodic processes such as file reorganization or end-of-period processes, application maintenance, or application migration. This research introduces a new middleware service called Active Persistent Service. Unlike regular middleware persistent services, this active service can provide consistent responses instead of the unavailable applications for other applications. This service helps increase the integration availability of distributed applications without fully replicating the application environment such as application platforms, application programs and application data. The proposed service can be used to maintain the integration among distributed applications during scheduled unavailability of one of these applications. In addition, the proposed service enables highly available applications integrations while maintaining the data and state consistency of the applications. This service provides a cost-effective solution for increasing the availability of applications integration. Key words: Middleware, highly available applications, distributed information application

Backup & Recovery
2006Co-Authors: W. Curtis PrestonAbstract:Packed with practical, freely available Backup and recovery solutions for Unix, Linux, Windows, and Mac OS X systems -- as well as various databases -- this new guide is a complete overhaul of Unix Backup & Recovery by the same author, now revised and expanded with over 75% new material. Backup & Recovery starts with a complete overview of Backup philosophy and design, including the basic Backup utilities of tar, dump, cpio, ntBackup, ditto, and rsync. It then explains several open source Backup products that automate Backups using those utilities, including AMANDA, Bacula, BackupPC, rdiff-Backup, and rsnapshot. Backup & Recovery then explains how to perform bare metal recovery of AIX, HP-UX, Linux, Mac OS, Solaris, VMWare, & Windows systems using freely-available utilities. The book also provides overviews of the current state of the commercial Backup Software and hardware market, including overviews of CDP, Data De-duplication, D2D2T, and VTL technology. Finally, it covers how to automate the Backups of DB2, Exchange, MySQL, Oracle, PostgreSQL, SQL-Server, and Sybase databases - without purchasing a commercial Backup product to do so.For environments of all sizes and budgets, this unique book shows you how to ensure data protection without resorting to expensive commercial solutions. You will soon learn to:Automate the Backup of popular databases without a commercial utilityPerform bare metal recovery of any popular open systems platform, including your PC or laptopUtilize valuable but often unknown open source Backup productsUnderstand the state of commercial Backup Software, including explanations of CDP and data de-duplication SoftwareAccess the current state of Backup hardware, including Virtual Tape Libraries (VTLs)

LISA - Using Gigabit Ethernet to Backup Six Terabytes
1998Co-Authors: W. Curtis PrestonAbstract:Imagine having to prove everything you believe at one time. That is exactly what happened when I was asked to change the design of an Enterprise Backup System to accommodate the Backup and restore needs of a new, very large system. To meet the challenge, I’d have to use three brand-new pieces of technology and push my chosen Backup Software to its limits. Would I be able to send that much data over the network to a central location? Would I be forced to change my design? This paper is the story of the Proof of Concept Test that answered these questions.
