For data protection, you may don’t have enough time to create a full disk image day by day, which will waste time and disk space. Set and Forget - The data on disk is modified, updated and added every day. The following criteria can help you evaluate the best hard drive imaging software. When looking for a free disk imaging software, it is important to make an informed decision on which product is right for you. Therefore, system administrators create a disk image with fully prepared applications environment of a well-adjust system to quickly deploy it to each computer by using PXE network boot.

OS Deployment: Large companies often need to buy large numbers of new computers with same or different hardware. Thus, disk imaging is an alternative way to directly clone.
