You can't be over-vigilant re backing up systems and data and this is where imaging software is a vital tool.
Disk Image installed swiftly for me and, following registration, launched a simple screen with options to make a complete image of my entire PC system, an image of one or more drives, an incremental image updating from an earlier image, cloning a drive or performing a restoration of an earlier image onto a new drive. When testing, I found DiskImage worked smoothly and quickly made an image of my 90GB of data in just over an hour and is ready for a restoration should disaster strike.
There are many imaging software packages available eg Acronis True Image but DiskImage is a little different and it goes further because it also offers 'PC Mover Image Assistant', an extra utility that lets you selectively restore programs, files or folders rather than copying an entire disk image onto the destination disk. This means it is possible to do a selective restoration without automatically overwriting data already on the destination drive - and hence losing it. It also means that a restoration can be tested to check that it works before risking deleting an entire operating system. The time when this utility could be most beneficial is when switching to a new computer (using the same or a later operating system) as it allows all data, programs and settings to be easily copied onto the new computer without having to laboriously reinstall software, register programs and set preferences, favourites etc. It does what it says - it moves whatever you select onto a new PC.
It is a very easy to use package for a beginner or more experienced user. Imaging software is an essential investment for anyone wanting to safeguard their system or transfer programs/data/settings to a new machine and at this price, it would be hard to find a product offering better value for money.
