Data security is now a necessity in small to medium sized businesses for the following reasons:

• Legal requirements
• Taxation responsibilities
• Accounting needs
• Disaster management
• Data Mining
• Privacy

Data security faces a number of modern threats:

• External / internal 'hacking' leading to industrial espionage, invasion of privacy and data theft
• Computer Virus, worms, trojans and browser drive-by infections
• Natural disasters like earthquakes, fire, floods etc
• Power outages
• Equipment and storage system failures

For these and numerous other reasons it makes good sense to have strategies in place to negate or at least minimise data damage or loss.
