SharePoint 2010: An update conflict has occurred, and you must re-try this action (Eng)

I started to get this message everytime I try to Backup Farm.

"An unhandled exception occurred in the user interface.Exception Information: An update conflict has occurred, and you must re-try this action. The object SessionStateService Parent=SPFarm Name=SharePoint_Config is being updated by DOMAIN\username, in the w3wp process, on machine XXXXXX.  View the tracing log for more information about the conflict."

To resolve this issue, clear the file system cache on all servers in the server farm on which the Windows SharePoint Services Timer service is running.
To do this, follow these steps:

1. Stop the Timer service. To do this, follow these steps:
  • Click Start, point to Administrative Tools, and then click Services.
  • Right-click Windows SharePoint Services Timer, and then click Stop.

2. Delete or move the contents of the following folder:

%ALLUSERSPROFILE%\Application Data\Microsoft\SharePoint\Config\[GUID]

3. Start the Timer service. To do this, follow these steps:
  • Click Start, point to Administrative Tools, and then click Services.
  • Right-click Windows SharePoint Services Timer, and then click Start.
Note: The file system cache is re-created after you perform this procedure.

Make sure that you perform this procedure on all servers in the server farm on which the Timer service is running.
