Chapter 13: Backup and Disaster Recovery

Bad things happen to good computers. And the most dangerous threat to most data? Users.

Most people assume backups are to protect you against disasters, such as fires or the upstairs bathtub overflowing and pouring soapy water into your computer in the office below. But users delete most files by accident. For example, with one twitch of the mouse a user might highlight the wrong file, or a user might think format means to put into data columns when it really means to erase a hard disk.

An insurance company in the United Kingdom did a study in the spring of 2003 and learned that nearly half of all small firms that have disasters, such as a complete system failure or fire, never recover. Nine of ten firms that lose data in a disaster are forced to close within 2 years.

More bad news? Less than half the small businesses studied had any type of contingency plan such as backed up computer systems to help them recover from a disaster. Because you're smart enough to pick up this book, I assume you're in the half who wants to prepare.

Tools to protect data exist in greater numbers, work better, and cost less today than ever. I will show you a dozen different ways to protect and backup data. You can do this automatically, manually, to tape, to CD-ROM, to hard disk, to online service, and even to paper, but please do it.
