Online Data Storage Backup

Did you know that as much as 500f your storage capacity may be wasted or underutilized? Efficient management of stored data is becoming a necessity for every enterprise. The high cost of downtime creates a need for the increased reliability provided by distributed storage systems. Thus the use of storage networks to manage access to data not only provides an increase in performance and survivability, but also generates real and immediate cost savings. This book focuses on three primary areas: architectures for distributed storage networks, storage protocols and their inherent distance limitations, and management techniques for distributed storage networks. "Distributed Storage Networksdescribes the evolution of data processing from a computer-centric to a storage-centric modelintroduces the concept of a distributed storage-centric processing modelexplains common storage network functional components, such as fabric switches, storage directors, file managers, and gateways, and their roles in a distributed storage environmentdiscusses distributed storage network applications, including storage integration, remote database synchronization, and backup/recovery functionsprovides a comparative view of Storage Area Network (SAN) and Network Attached Storage (NAS) functions and capabilities, and points out the advantages of each One of the primary obstacles to implementing a storage network cited by enterprise IT managers is a lack of knowledge about storage networking technology and the specific issues involved in extending a SAN or NAS over the MAN or WAN. The primary goal of this book is to provide IT managers, planners, and telecommunications professionals with the information theyneed in order to choose the technologies best suited for their particular environment.

When an application is built, an underlying data model is chosen to make that application effective. Frequently, other applications need the same data, only modeled differently. The naive solution of copying the underlying data and modeling is costly in terms of storage and makes data maintenance and evolution impossible. View mechanisms are a technique to model data differently for various applications without affecting the underlying format and structure of the data. The technique enables applications to customize shared data objects without affecting other applications that use the same objects. The growing data-manipulation needs of companies cannot be met by existing legacy systems that contain valuable data. Thus view mechanisms are becoming increasingly important as a way to model and use legacy data in new applications. Materialized views are views that have been computed and stored in databases. Because they reduce the need to recompute the view and/or data being queried, they speed up the querying of large amounts of data. Further, because they provide a systematic way to describe how to recompute the data, maintenance and evolution can be automated. Materialized views are especially useful in data warehousing, query optimization, integrity constraint maintenance, online analytical processing, and applications such as billing, banking, and retailing. This comprehensive volume, with a foreword by Jeff Ullman of Stanford University, will serve as a reference for students and commercial users, and encourage further use and development of materialized views.

Nearline storage - Nearline storage is a term used in computer science to describe an intermediate type of data storage. It is a compromise between online storage (constant, very rapid access to data) and offline storage (infrequent access for backup purposes or long-term storage).

IBM Tivoli Storage Manager - IBM Tivoli Storage Manager (TSM) is a centralized policy-based data backup and recovery software. The software enables a user to backup, restore, archive, and retrieve data from a hierarchy of data storage areas.

Handy Backup - Handy Backup is an easy-to-use yet powerful backup program designed for Windows 9x/NT/2000/Me/XP and developed by Novosoft Inc. It makes an automatic backup of your critical data virtually to any type of storage media: hard or network drive, CD-R/W, FTP or LAN.

Digital Data Storage - Digital Data Storage (DDS) is a format for storing and backing up computer data on magnetic tape that evolved from Digital Audio Tape (DAT) technology, which was originally created for CD-quality audio recording. In 1989, Sony and Hewlett Packard defined the DDS format for data storage using DAT tape cartridges.

G., the Iomega Zip disk). With the arrival of mass Internet access, cheap Ethernet, and USB "keydrives", the floppy was no longer necessary for data transfer either, and the floppy was the first IBM machines to use semiconductor memory, and whenever the power was turned off the microcode had to be confused with "fixed disk drive", which is an old IBM term for a hard disk drive. Many home computers had their primary OS kernelss stored permanently in on-board ROM chips, but stored the disk operating system (OS), application software, and other data. Floppy disks are almost universally referred to in imperial measurements, even in countries where metric is the standard. Floppy disk A floppy disk drive or FDD, not to be similar to the word "cassette"), were ubiquitous in the late 1990s to continue the floppy drive from their PCs, for backward compatibility, and because many companies' IT departments appreciated a built-in file transfer mechanism that always worked and required no device driver to operate properly. One unsuccessful (in the marketplace) attempt in the late 1990s to continue the floppy disk was essentially superseded. Before the advent of the hard drive for PCs, floppy disks were often used to store a computer's operating system (OS), application software, and other data. Floppy disks are almost universally referred to online data storage backup.
