Can't Create System Image Solved

    Can't Create System Image

    I'm using Windows 10 Home on another computer in the house and backing up to a NAS using Windows Backup, and I'm unable to create a system image.

    I'm getting an error about the virtual disk being compressed or encrypted (which it is not) and it stops with a failed backup. I have a 64 GB SSD main drive for booting and a spinner for programs and User files. I'm using about 45 GB on the SSD.

    Is the reason that I can't create the system image because there is not enough space on the boot drive to accommodate it? This is my best guess anyway, but I would appreciate any other theories.

    You cannot create image to save drive you boot from. Even if you could, there is not enough free space to backup 45GB anyway.

    @Gurn Blanston clearly stated they weren't, the backup was to be to a NAS drive. However, the Volume Shadow Copy Service (VSS) is. It is trying to create a shadow copy of the drive in order to create the system image from it.

    Even if you could, there is not enough free space to backup 45GB anyway.
    That would appear to be exactly the problem that VSS is encountering.

    The solution would be to free up some space on the system drive. If you have not already done so, use Disk Clean up and clean up the system files. Make sure you also use Option One, Step 7 'To Delete all but the most recent Restore Point' in this tutorial.

    Turn off hibernation (you can turn it back on again when you're done, if you wish). This will remove the hiberfil.sys file it uses. In an elevated command prompt:

    Configure virtual memory so that there is no page file on the system drive.

    The above may be sufficient to allow VSS to work. I believe the shadow copy is compressed, so you probably don't need a full 50% of the drive free.

    If it still fails after a clean up, post the full error message you get. A screenshot will do...

    Hi Bree. I tried all of the suggestion you made, and I was able to increase the drive space to 24 GB, but it still seems to be not enough. It failed.

    This is the error message that I got:

    I'm still learning my way around in Windows 10, but if this happened to me in Windows 7, I would assume that I don't have enough drive space to make the System Image VHD file.

    And I think that is the case here.

    I'm thinking that I might have to do this with Macrium.

    Googling those error codes the common factor is trying to back up the system image to a NAS....

    Problem was not win 10 but my NAS....
    Normally I just backup files/folders to a networked NAS using Cobian Backup. This is the first time I tried making a system image...


    ...There are work-arounds for this on the web. Essentially, it amounts to adding the line "strict allocate = yes" to the Global section of the NAS' smb.conf file...

    Or try putting the system image on an external USB HDD instead... or you could just use Macrium :)

    As far as I know Windows 10 System Images to a NAS box does not work.
    I discussed it back in October 2016 with the NAS box manufacturer(Synology) and MS. The latter finally came back and said you can't use a NAS box despite being able to specify a suitable location on the NAS box.

    I had similar error boxes as in post #6.

    There have been updates to Windows 10 and the NAS box. I have not tried since. I now use Macrium which does work.

    This used to work under Windows 8.1, I still have 2 Images on the NAS box from June 2016 done just prior to the Windows 10 install, also same date 2 Macrium Images as I used both back then.

    Thanks for the help everyone. I am going to use Macrium to make an image. Maybe I can get it to work. In the meantime, I'm going to mark the thread as solved.

    Thanks again for your efforts. :)
