This software has saved my bacon on so many occasions. It is wonderful for "event driven" backup imaging, specifically prior to the installation of new software. It allows you to test the software and, if it does not work as expected or interferes with existing software, you can reformat your disk and restore it to the exact state prior to when you started.
