Disaster recovery services are indispensable in the modern age of technology. Many of companies focus on specific aspects of disasters. For example, some put emphasis on hot sites which allow businesses to maintain computer and network operations in the event of an equipment disaster. Others specialize in hard disk recovery which allows businesses to restore and retrieve data from PC’s, servers, and mainframes following a major disaster. Another component of data recovery is the recovery of magnetic tapes. Magnetic tapes act as a storage medium for pictures, sounds, or computer data and may hold vital information from few or many years past.
