Ninety-three percent of the companies lacking a recovery plan are out of business within five years of a major disaster. Despite these claims, few companies plan ways to prevent or mitigate losses. To protect the bottom line, companies need to evaluate potential losses and implement an appropriate availability scheme for their network. A good starting point is to review the availability mechanisms that Windows NT Server supports. So when planning a network, you need to consider availability, backup, and disaster recovery.
Most network administrators implement availability by a mirroring of the primary system.
This redundant system eliminates single points of failure. Fortunately, NT Server comes with support for tape backup, UPS, and redundant systems. Critical Data and Programs Data backup is at the forefront of availability. The backup process copies important information onto magnetic tape or disks. Backing up information is also important because of its changing nature.
