Storage Network Back-up
Network back-up systems can back up heterogeneous IT environments incorporating several thousands of computers largely automatically. In the classical form, network back-up systems move the data to be backed up via the LAN
Before getting involved in technical details, we will first discuss a few general conditions that should be taken into account in back-up (Section 7.1). Then the back-up, archiving and hierarchical storage management services will be discussed (Section 7.2) and we will show which components are necessary for their implementation (Sections 7.3 and 7.4). This is followed by a summary of the measures discussed up to this point that are available to network back-up systems to increase performance (Section 7.5). Then, on the basis of network back-up, further technical boundaries of server-centric IT architectures will be described (Section 7.6) that are beyond the scope of Section 1.1, and we will explain why these performance bottlenecks can only be overcome to a limited degree within the server-centric IT architecture (Section 7.7). Then we will show how data can be backed up significantly more efficiently with a storage-centric IT architecture (Section 7.8). Building upon this, the protection of file servers (Section 7.9) and databases (Section 7.10) using storage networks and network back-up systems will be discussed. Finally, organizational aspects of data protection will be considered (Section 7.11). The consideration of network back-up concludes the use of storage networks.

|ABOUT THE BOOK:|
|Storage networks will become a basic technology like databases or local area networks. According to market research, 70% of external storage devices will be connected via storage networks in 2003. The authors have hands-on experience of network storage hardware and software, they teach customers about concrete network storage products, they understand the concepts behind storage networks, and show customers how storage networks address their business needs. This book explains how to use storage networks to fix malfunctioning business processes, covering the technologies as well as applications -- a hot topic that will become increasingly important in the coming years.Purchase the book from Wiley Publishing|
