This book was written for a CommVault Administrator, either new or experienced, who wants to have a quick and easy reference to the major features and functionality of the Common Technology Engine. Nearly all interaction with the software is through the CommCell Console Graphical User Interface with its tools, control panel, and management objects. It therefore makes sense that this structure provide the basis for the organization of this book. A reader familiar with the softare, or with access to a CommCell Console should easily be able to find the information they need in this book.
