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.
