Images vs. Backups

We all know that backing up our data is important, especially when upgrading to a new version of Windows. But rather than fiddle around with partitions purely for personal data, or cloud storage, which might be slow to restore your vital files and folders, wouldn’t it be great to be able to simply take a backup of your entire Windows installation?


Such a backup might be configured to include your personal folders, but omit apps and games, or you could opt to create an image of your entire system drive. Naturally, you would need a suitable volume of storage for such a backup.

Images and Disk Upgrade or Replacement

One popular use for disk images is creating a clone of your hard storage (hard disk drive or solid state drive), which might be on its last legs.

After downloading and installing the utility, use the Clone tab to select the drive you wish to make an image of; to clone multiple drives, use the Batch Clone tab.


Select the destination location and assign a filename in the Output image file as box, where you should select the target disk drive – the device purchased to replace the old HDD.

In Advanced Startup Options, select Repair your Computer > System Image Recovery and follow the instructions, ensuring that Windows can find the ISO file.

    I can't believe how many of these articles simply are incorrect in detail.
    I read through them, I follow the steps and they bear no relation at all to Windows 10.
    There is NO file history app on my computer that I can find.
    Please, if you're writing something make sure it's correct so that when we follow all your steps we actually get somewhere instead of just wasting time over and over again.

    Hey, your instructions are incorrect under Restoring the Windows 7 Disk Image
    You state "...You can then use this to boot your PC and select the System Image Recovery option to restore the ISO Disk Image of your Windows installation following a disaster scenario."
    This is wrong info. The image is NOT an ISO image!!! Hello!!!

    Will writing an ISO file to an external drive using DDKI erase the data from this drive?

    A bit curios too as to why this process doesn't create an .ISO file, just folders - as others have mentioned. How do you turn this information into an .ISO?

    I followed the "Creating an ISO Disk Image in Windows 7" instructions above, and it created a backup folder at the target location, but it wasn't an .ISO file, which is what I need.

    Recommending the internal W10 iso imaging thorugh [File history] maybe
    helpful for users not really caring about this spy-OS only.

    I disabled all sneakers including system restore, error reportings
    and removed Cortana which is one of MS personal data snatcher
    clumped in a useful user tool.

    Got a nice and smoothe working W10 now.

    But you can't have one without the other - no internal iso,
    no recovery anymore.

    Trying to create a recovery drive leads to this:

    "We can't create a recovery drive anymore...some files are missing".

    "We can't...", MS arrogance means "We don't want".

    So I'll go walk with Acronis another decade.

      Agreed that the MS recovery tool isn't perfect, but it is your choice to use Acronis. If Redmond don't have the resources to put into building a complete backup solution, then it is an opportunity for others. Let's celebrate that, rather than decrying Microsoft.

    Using Windows to make an image is challenging. Every version of Windows since Vista has had a feature to make system backups. But each version has a different process for creating and restoring the image.

    I recommend using a third party program like Acronis or Macrium. I can make the backup image using an old versions of Acronis using a bootable media such as a CD/DVD or USB device. I can restore the image using any other version of Acronis. I only need to learn how to use one product.

    I use Macrium Reflect (free) for backup purposes and it does basicly the same as described in the article. You should also use it before an upgrade to win 10 or any other major changes to your system.

    This whole ISO image thing seems kind of "clunky" to me :-) I use Acronis True Image and I have ONE big file on my "backup server" of my systems running across the network, using a bootable CD with the Acronis program on it. Some of my systems (I have many) have usage of over 1-200 GB total on the hard disk. That's a LOT of DVD's or ISO image files to keep track of :-) hehe and 200 GB would be at least 8 Blue Ray's... crazy expensive...

    Acronis is a lot simpler :-)

    Making a clone prior to chancing your luck on a Windows 10 update is the most sensible thing anyone can do and I cant stress that enough. Microsoft may have tested the update process on new hardware like HP, Dell or Acer for example, but they have failed abysmally testing it on generic hard ware and their drivers for very capable PC's of circa 2012 or earlier. Even my new TV stick (2015) fails an upgrade from Win 8.1 to Win 10 so they obviously didn't bother to test the process on that.

    Play safe and create a clone then at least you can fall back.
