What's the worst thing that can happen to your computer? Worse than a hard disk crash, virus infection, spam assault, denial-of-service attack, hacker take-over, fire, flood, or other human, mechanical or natural disaster is a faulty backup when you really need it. If the computer blows up, as long as your data is backed up securely, you can recover. Tape backup is still popular among business users because of its long use and cost-effectiveness per megabyte of data. This is despite the increasing popularity of other backup solutions. Many home and small businesses use recordable CDs and DVDs to back up newly created data. Various types of computer users are now employing an external hard drive, connected to a USB port, to quickly and cost-effectively back up entire hard drives. And those with broadband Internet connections can use Internet backup services to conveniently store selected backup data offsite.
