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

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"

    The System Reserved partition contains the boot files and the BCD on MBR-based disks. By default, Windows creates this partition during the setup. As we've copied the boot files and the BCD to the C:\ drive, the C drive now serves as both the Windows partition and the boot partition.
