Operating Systems: 

    This article cover errors and failures during disk management operations in Acronis Backup, including cloning, conversion and volume deletion/creation issues. It provides possible causes for the errors and how to troubleshoot the issues.

    Before anything else, be aware that these operations can lead to data loss! Before running any operations through disk management, make sure you have acquainted yourself with the basic precautions listed in the following documentation.


    Most problems with disk management operations stem from limitations related to specific disk and file-system formats. Please make sure you have acquainted yourself with the relevant information on these limitations (specific to the operation you want to run):

    Known issues

    Please note that Disk management operations are not available under Windows 8/8.1/10, Windows Server 2012/2012 R2/2016 and that disk management operations under bootable media may work incorrectly if storage spaces are configured on the machine. You can find out more about storage spaces in this article.


    Please note that these operations cannot be run directly from inside a live OS because the disks or volumes will be locked. This means that running an operation from a live OS will require a reboot into a special Acronis bootable environment. Configuring this environment can end in failure due to Windows conflicts (for example, registry access problems). The first step in troubleshooting disk management problems is to perform the same operation under the latest version of Bootable Media. If the machine you are using boots via UEFI, the bootable media also has to be booted in UEFI mode.

    If the operation fails using our bootable media, depending on the system, collect the following information:

    • If the operation hangs, please follow the instructions in this article under the “Linux-based bootable media” section.
    • If the bootable media reboots during the operation, this is a crash. Please follow the instructions in this article.
    • If the operation fails with an error, please follow the procedure below:
      - Run the operation;
      - After it fails, do not reboot the machine!
      - Go to the Logs view, change to Events display and save all to file;
      - Again, without rebooting, go to the Help -> Collect system information menu and save the file.
      - Provide a description of the storage sub-system being used on this machine (type of disks, connection to storage etc.)
