Imagine working weeks or months on a project and losing everything when the computer file is lost or damaged. Be sure to make backup copies of your computer data, store them securely, and consider storing additional copies at another location. 

Depending on how much data you have, or expect to have, there are several options for backup media, including computer backup tape, external hard drives, ZIP disks and CD-RW. When purchasing a new computer, it is a good idea to get one that has one or more of these backup options included. It is also very important to retain and safeguard the original operating system media for your system.

What to Back Up
It is a good idea to take weekly backup of your important documents. The examples may include following:

· Internet URLs.
In addition to your connection information, chances are that you want to save your Web site shortcuts or URLs. For example, if you're using Internet Explorer, you'll find the URLs in the C:\Documents and Settings\Your Username\Favorites folder. Simply back up the entire Favorites folder to tape or floppy disk.
If you're using another browser or operating system, check with your documentation to find out where and how your URLs are stored. Then, back them up.

· E-mail folders and address books.
If you want to keep your address book and e-mail folders intact, you'll need to back up the corresponding files. For example, if you're using Outlook Express, you'll track down your address book by using Find to search for a file with the extension WAB. You'll then track down your e-mail folders by using Find to search for a folder called Mail. This folder contains all your e-mail folders as well as links to any newsgroups that you subscribe to.
If you're using another e-mail program, check with your documentation to find out where the files containing your e-mail folders and address book are stored. Then, back them up.

· Application information.
If you're using Microsoft Office or some other application suite, you should also backup any templates, macros, or other customized items that you don't want to have to recreate. For example, suppose that you're using Word and you've created a lot of macros that help you to quickly an easily produce your documents. You'll find most of your macros stored in Word's templates. By default, macros are stored in the template. If you've created a custom template for your word processing needs, the template also probably has macros stored in it.
