OK, I m scared about a disk crash. The key issue here is to establish a backup program that fits your computer usage, realistic worse case scenarios, and budget. You must imagine the worst possible situation and prepare for it. For example, the most compulsive backup program wouldn t help if the tapes burned in the same fire as your office. Finally, cost is not an issue.
Backup systems are cheap.
Frankly, you can t afford not to backup. Most contemporary home computer systems don t need much of a backup system. The software usually comes on a CD-ROM and can easily be reinstalled. Reinstalling from a CD-ROM is usually easier and more intuitive than using a backup tape. However, you should have selected data on tape or on floppies.
