Disk-level backup to cloud fails with error:
Error code: 1060
Module: 1
LineInfo: 0xB43E776571144DEE
Fields: {"$module":"disk_bundle_vs_1088"}

Message: Internal error: different hash after rebackup


The issue occurs on NTFS partitions and indicates that the partition might have bad sectors. We recommend checking disk integrity with the Check Disk tool. Issue:
chkdsk /f

To resolve the issue:

  1. Open Windows Registry: Start -> search -> type regedit.exe and press Enter.
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\MMS\Configuration\General\Protection\. If the key Protection does not exist, create it.
  3. Create a DWORD named "InternalDeduplication" and set its value to "1".
  4. Restart Acronis Managed Machine Service: Start -> search -> type services.msc and press Enter -> locate Acronis Managed Machine Service and click Restart.

You can also download the file id_enable.zip and do the following:

1. Unzip the archive to any local folder.

2. Launch the ID_enable.bat as the administrator.


  1. Open the /etc/Acronis/MMS.config
  2. Find the line with the <key name="General"> and the key "Protection" under it. Create it if it does not exist.
  3. Set its value to "1":

<key name="Protection">

<value name="InternalDeduplication" type="Tdword">
