Check the system performance and resources

This event indicates that the computer is under heavy I/O load or is low on resources.

To resolve this issue, reduce the system or I/O load and retry the operation, or schedule Volume Shadow Copy Service (VSS) or other operations during the least busy periods for the computer.


To verify that the Volume Shadow Copy Service (VSS) can create a volume shadow copy, perform the following procedure, and then retry the previous VSS operation.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To verify that the VSS service can correctly create a volume shadow copy of the system volume:

  1. Open an elevated Command Prompt window. Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
  2. Type diskshadow, and then press Enter.
  3. Type add volume <Volume>, where Volume is the drive letter for the system volume, and then press Enter.
  4. Type create, and then press Enter.
