Many computer users “know” we “should” back up, but many never get around to it. Use the built-in Windows backup program (Ntbackup.exe in Windows NT, 2000, and XP) or a third-party backup program and schedule backups to occur automatically. You can also store backed up data on another server or removable drive in a location away from the computer itself, in case of a natural disaster like flood, fire, or tornado. Create mirror images of your disks using popular ghost or clone programs.”]
