Backing up your hard drive is an important step towards protecting yourself from devastating data loss and file corruption. While some prefer to only backup certain files, others find it simpler to backup the entire contents of a hard drive. By saving an image of your hard drive as an ISO, you can quickly and easily restore your backed up data. There are many programs to help you with this, such as ImgBurn and Nero BackItUp.
Download ImgBurn (see Resources). This free program allows you to create ISOs.
