Basics

16.1. What Does “Backup” Mean?

Put simply, a backup is a copy of your data to ensure that, in case the original data is lost (some reasons are given in FAQ 16.2), you can recover from this loss by using the backup copy of your data. Backup data is generally kept on a different storage medium and at a different location than the original data; this is to ensure that if the original data is corrupted or lost, the cause of that loss does not affect the backup data. The action of creating a backup is called backing up. In relation to Outlook, a backup is essentially a copy of all your Outlook items, such as your e-mails, contacts, tasks, and rules.

Almost all organizations have their own backup policies and procedures to ensure that if there is a loss of data (whether minor or catastrophic), they can recover as much as possible the data that was lost. Backup policies and procedures normally encompass details ranging from the type of storage to use (hard drive, tape, optical), to how often a backup is created, to where the backup is stored, to what exactly is done, and by whom. Now, chances are good that you, as an individual, will not need to have defined complex policies and procedures, but keeping regular backups of your data is common sense. Accidents do happen; at least if you have a backup, your day, week, month, or year won't be completely ruined.
