Good backup and recovery strategies are key to the health of any organization. Medium- to very-large-scale systems administrators have to protect large amounts of critical data as well as design backup solutions that are scalable and optimized to meet changing conditions. Pro Data Backup and Recovery will cover some of the more common backup applications, such as Symantec NetBackup/BackupExec, EMC NetWorker, and CommVault, but the main discussion will focus on the implementation of 21st century architectures that allow the backup software to be a “commodity” item....
The data center is home to the computational power, storage, and applications necessary to support an enterprise business. The data center infrastructure is central to the IT architecture, from which all content is sourced or passes through. Proper planning of the data center infrastructure design is critical, and
performance, resiliency, and scalability need to be carefully considered.
The data center is the repository for applications and data critical to the modern enterprise. The
enterprise demands on the data center are increasing, requiring the capacity and flexibility to address a
fluid business environment whilst reducing operational costs. Data center expenses such as power,
cooling, and space have become more of a concern as the data center grows to address business
Blade servers are the latest server platforms that attempt to address these business drivers.
Economic thinking is all about making difficult choices. Critical economic
thinking is all about being aware of how you think about economic issues so
that you can make the best decisions possible. All of us engage in economic
thinking whether it is shopping for ourselves, making business decisions that affect
our fellow workers, or deciding on government policies that affect the entire
nation. Of course such decision making is not done solely from an economic
perspective. Shopping decisions are affected by a variety of cultural influences.
For small, medium, and large businesses, it is critical to provide high availability of data for both
customers and employees. The objective behind disaster recovery and business continuance plans is
accessibility to data anywhere and at any time. Meeting these objectives is all but impossible with a
single data center. The single data center is a single point of failure if a catastrophic event occurs. The
business comes to a standstill until the data center is rebuilt and the applications and data are restored....

Relational databases, the heart of storing and processing data in the enterprise for over
30 years, are no longer the only game in town. The past seven years have seen the birth
—and in some cases the death—of many alternative data stores that are being used in
mission-critical enterprise applications. These new data stores have been designed
specifically to solve data access problems that relational database can’t handle as
An example of a problem that pushes traditional relational databases to the breaking
point is scale.

This book is for developers who design and program devices that use the
Universal Serial Bus (USB) interface. My goal is to introduce you to USB
and to help you get your devices up and communicating as quickly and easily
The USB interface is versatile enough for a wide range of peripheral devices.
Standard peripherals that use USB include mice, keyboards, drives, printers,
and audio/video devices. USB is also suitable for data-acquisition units, control
systems, and other devices with specialized functions, including

This comprehensive, leading-edge book reveals the techniques and strategies to help you keep enterprise data and voice networks in service under critical circumstances. You learn numerous ways to minimize single points of failure through redundancy and backups, and discover how to select the right networking technologies to improve survivability and performance....
THE EAST ASIAN FINANCIAL CRISIS: A CRITICAL EXAMINATION OF FOUR ALTERNATIVE MODELS David Card and Alan
Krueger provided the SAT data used throughout. Cecilia Rouse provided the hard-to-obtain
School District Data Book used in Chapters 1 and 2. Saul Geiser and Roger Studley of the
University of California Office of the President provided the student records that permitted
the research in Chapter 3.

The sub-series Ternary Alloy Systems of the Landolt-Börnstein New Series provides reliable and
comprehensive descriptions of the materials constitution, based on critical intellectual evaluations of all
data available at the time and it critically weights the different findings, also with respect to their
compatibility with today’s edge binary phase diagrams. Selected are ternary systems of importance to
alloy development and systems which gained in the recent years otherwise scientific interest.
Congestion occurs when the number of packets being transmitted through the network approaches the packet handling capacity of the network
Congestion control aims to keep number of packets below level at which performance falls off dramatically
Data network is a network of queues
Generally 80% utilization is critical
Finite queues mean data may be lost

The care of the critically ill has changed
radically during the past 10 years. Technological
advances have improved monitoring,
organ support, and data collection, while small
steps have been made in the development of drug
therapies. Conversely, new challenges (e.g. severe
acute respiratory syndrome [SARS], multiple
antimicrobial resistance, bioterrorism) continue
to arise and public expectations are elevated,
sometimes to an unreasonable level.
Data-intensive applications, challenges, techniques and technologies: A survey on Big Data has been one of the current and future research frontiers. In this year, Gartner listed the Top 10 Strategic Technology Trends For 2013 and Top 10 Critical Tech Trends For The Next Five Years, and Big Data is listed in the both two.
The new version of PHP is out. RC4 was the last step
before the final release—developers have been asked to
commit to the PHP CVS repository only changes that fix
bugs marked as “critical” in the bug tracking system,
and thankfully only lasted a few days.
The PHP developers have also solved a dilemma that
has all but dominated the mailing lists of late—the
naming of the CLI (command-line interface) version of
PHP vs. the CGI executable, which is used when using
PHP as a separate executable to run scripts through a
