A backup is an exact copy of your company data file. Every prudent businessperson should ensure that a functioning backup system is in place. If you use a backup process that backs up your entire computer system, your QuickBooks company file is included as part of the entire backup so you don't need to back up that file separately. If you instead back up specific files individually, these steps will demonstrate how to back up just your company's QuickBooks information. Consider backing up frequently and keeping a copy of your backed-up data somewhere off your company premises. For this example, you'll save your backup file to a disk. An online backup procedure is presented later in this chapter.
