files on the machine with Acronis Agent this error is reported:

"database disk image is malformed"

1. Stop Acronis Storage Node Service/Managed Machine Service if it is started.

2. Rename the folder:

  • Windows XP/2003: %ALLUSERSPROFILE%\Application Data\Acronis\BackupAndRecovery\ASN\DmlDatabase
  • Windows Vista/2008/7/2012/8/8.1: %ProgramData%\Acronis\BackupAndRecovery\ASN\DmlDatabase


  • Windows XP/2003: %ALLUSERSPROFILE%\Application Data\Acronis\BackupAndRecovery\MMSData\DML
  • Windows Vista/2008/7/2012/8/8.1/10: %ProgramData%\Acronis\BackupAndRecovery\MMSData\DML

3. Start Acronis Storage Node Service\Managed Machine Service.

The issue should be resolved this way. You can delete the old DML database after that.
