Back-up is always a headache for system administrators. Increasing amounts of data have to be backed up in ever shorter periods of time. Although modern operating systems come with their own back-up tools, these tools only represent isolated solutions, which are completely inadequate in the face of the increasing number and heterogeneity of systems to be backed up. For example, there may be no option for monitoring centrally whether all back-ups have been successfully completed overnight or there may be a lack of overall management of the back-up media.
Changing preconditions represent an additional hindrance to data protection. There are three main reasons for this:
- As discussed in Chapter 1, installed storage capacity doubles every four to twelve months depending upon the company in question. The data set is thus often growing more quickly than the infrastructure in general (personnel, network capacity). Nevertheless, the ever-increasing quantities of data still have to be backed up.
- Nowadays, business processes have to be adapted to changing requirements all the time. As business processes change, so the IT systems that support them also have to be adapted. As a result, the daily back-up routine must be continuously adapted to the ever-changing IT infrastructure.
- As a result of globalization, the Internet and e-business, more and more data has to be available around the clock: it is no longer feasible to block
- user access to applications and data for hours whilst data is backed up. The time window for back-ups is becoming ever smaller.
Network backup can help us to get to grips with these problems.

|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|
