Make sure you have a system in place to back up your Web site. Even the best Internet service providers have technical problems, so you should keep a backup of your site where you have easy access to it and can get it back online quickly. Update the copy regularly to make sure you have the latest version of your site backed up.

Also keep a backup of your original source files. For example, when you develop images for the Web, you usually start in a program such as Photoshop, creating a high-resolution image that may include layers and other elements. Before the image goes on your Web site, those layers are flattened and the image is compressed or reduced and converted to a GIF or JPEG file. If you ever want to go back and alter that image, you'll want the original source file. Whether you create your own images or hire a professional designer, make sure you develop a system for saving the original text, images, and other content.
