CAUSE

Creation of Acronis backup snapshot consumes more system resource than is available to the backup process.


SOLUTION

Use the following suggestions to free up system resources:

  • If the operating system is Windows 2003 Server, delete /3GB /userva=3030 from boot.ini;
  • In Windows Registry Editor, locate and change the following values (Start-Run -> regedit -> CTRL-F):

    PagedPoolSize to Hex-Value ffffffff (see also Microsoft Knowledge Base Article: Backup program is unsuccessful when you back up a large system volume)
    PoolUsageMaximum to Dez-Value 60

  • Increase the size of the desktop heap from 3072 KB to 4096 KB as described Microsoft Knowledge Base Article 126962:

    Open the following value in Windows Registry Editor:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems -> Windows

    And change the Value data to the following one:

    %SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,4096,512 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16

  • In Windows Server System Performance switch to optimal performance for Background service and System cache.

 

FURTHER INVESTIGATION
If you still encounter issues, please gather the following information and submit to Kaseya support: -
  1. Acronis log of failed backup (go to Backup > Backup Sets > click on 'failed' hyper-link in results column)
  2. Acronis Info tool output from Backup client
  3. details of any changes made after reading the Acronis article
