Hi, sorry for delay, I would like to continue in discuss about this issue

https://learn.microsoft.com/en-us/answers/questions/3863521/vss-(volume-shadow-copy-service)-writes-issue?forum=windows-windows_10-other_settings&referrer=answers

Hi, I use Acronis True Image for backuping my PC and now I started to having issue -

"There is not enough space on the volume where the snapshot storage is located"

Acronis support wrote me:

Since you're attempting to create a full PC backup, it requires a significant amount of storage space. It appears you're encountering storage-related issues. I recommend trying a disk-level backup for each individual backup present in your system to see if the issue persists.

Additionally, based on the screenshots and logs you provided, the issue seems to be related to VSS (Volume Shadow Copy Service) writers. As this is a Windows system component, I recommend contacting Microsoft Support to resolve the VSS writer issue. Once resolved, you should be able to proceed with backups successfully.

I am adding screenshot from the Acronis Disk Director.

How can I rise that?


we ended on

you said:

"Please run these commands:

takeown /f "Y:\System Volume Information" /r /d y

icacls "Y:\System Volume Information" /grant *S-1-5-32-544:F /t /c

rd /s /q "Y:\System Volume Information"

Once done, redo the steps listed in that Microsoft article."

so I did, then I went back to this page, as you said in that article and I got stuck on part 11.

"Type whoami and press Enter, and then record the user name. Type the following command and press Enter: icacls . /grant <username you got from whoami>:F /t

Note: Do not put a space between the username and ":F", or the command won't work."

it writes "access denied"

    Ok, I did that command with success.

    So should i now continue by the "Restore permissions" ?

    Or I can share you all the screenshots from that step, if you need

    "Type the following command and press Enter:

    icacls Y:\ /restore %systemdrive%\NTFSp.txt /c /t"

    The access denied errors are not normal. The output indicates that Step 9 in the article was not done from the correct directory. I have no way to verify this because the 'takeown' output wasn't posted.The ACLs are messed up now. To prevent the boot errors due to wrong ACLs, I'd suggest running the following command:

    bcdboot C:\Windows /s C: /f BIOS
    

    If that command runs correctly, open Disk Management and mark the C drive as the active partition.

    (After you have completed the above steps, the System Reserved partition will not be used by the OS. You can skipt that partition in Acronis.)

    Yes, the .ttf files have been deleted. No confirmation message will be shown if the operation was successful.

    příkaz 12

    about the step 12 - this is fine? I expected, it will write, that fonts were deleted or something, but no confirmation or something
