Incremental Backup Error: Cannot update image with Volume ID


I’m trying to set up Incremental Cloning for the first time. I have successfully created the image - which is one an external SSD.

My Bootcamp partition is on the internal Macintosh HD - created using Bootcamp Assistant in the normal way. When I try to select the partition in the Incremental Cloning Config, I get the following error:

"Cannot update image with Volume ID
The associated Windows volume ID could not be updated in the image at /Volumes/Bootcamp BU/Bootcamp.winclone. Please check permissions and try again

What does this mean - and how should I go about fixing it?

The only thing I can think of which is non-standard is that for convenience, I’m using a Parallels VM to use the Bootcamp partition from within MacOS. But I can still boot to the Bootcamp partition directly, if I want to.

The volume ID is saved to the Winclone image itself (which is a “bundle” type package) and this error means it can write inside that “bundle” (which is actually a folder). Try control clicking on the image, select Show Package Contents and a folder will open up. Try creating a new folder in that folder and see if you get a permissions error. If you do, that is why Winclone is failing. it can write to inside the image.


Thanks Tim.

I’ve shown package contents of the winclone image. And I’ve created a new folder inside the package - without any permissions error.

What should my next step be, please?


The other piece of information that is required is the partition ID, which on a GPT disk is called a “mediaUUID”. If you do a "diskutil info " in terminal, it will show the mediaUUID (under Disk/Partition UUID):

It is possible that the disk is formatted as a non-GPT disk and doesn’t have a media UUID.


OK, thanks - this is what I have:

I’m looking at the code right now, and the ways it can fail:

  1. No UUID on disk. You verified that isn’t true.
  2. It can read or write to the productInfo.plist in the image. Do you see a file named productInfo.plist in the image?


Yes productinfo.plist is in the image. Here are the contents:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">
    <string>Windows 10</string>

And I’m able to edit and save changes to the above productinfo.plist (don’t worry I’ve changed it back!)

Any further suggestions, possibilities gratefully received… :slight_smile:

I had a thought. Perhaps it is TCC that is blocking it (the new privacy controls). Try moving the image the root of your home folder (or to /Users/Shared) and see if it works.


That was a good thought, Tim! It worked!

So what should I change to allow it to use my external SSD?

Many thanks for your help.


OK, Progress. Having done the above, if I now change the destination back to the original image on my SSD - with the source partition already set and accepted - I can now run the incremental backup.

However - it runs for several minutes and I then get the following error:

**There was an error updating the image. Verify Windows was shut down cleanly, run CHKDSK and try again.**

I’ve run CHKDSK and made sure that Windows was shut down properly, but I still get the above error.

If you look in the log, does it show any file related errors? You can open the log right in Winclone.


I also use Parallels by getting it to run the version of Windows on Bootcamp. After an initial first image and 3 successful incremental back ups, I’ve also hit a snag with the same error message “There was an error updating the image. Verify Windows was shut down cleanly, run CHKDSK and try again.” I’ve shut down Windows via bootcamp as well as in Parallels. For me, in the log, two error codes come up. The first is “ERROR: Exiting with error code 47” and the second is [ERROR] Can’t open “/Volumes/Backup Plus/filename.winclone/Windows.wim” read-only: No such file or directory”

The issue is that Winclone cannot write to the WIM file on the external drive. Check permissions and try again.
