Recreate The Shadow Copy | Windows Backup Failure

I am receiving the message "Windows backup failed while trying to read from shadow copy on one of the volumes being backed up  " when back up operation is run. I changed some back up folders and deleted some files on back up drive and think this is related to problem.  I need to know how to recreate the "shadow copy".

Solution:

This could be Volume Shadow Copy service and SPP services are not started.

To restart the Volume Shadow Copy service and SPP services you must be logged on as an administrator to perform these steps:

• Open Administrative Tools by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Administrative Tools.
• Double-click Services. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
• If the SPP service is disabled, double-click it to open the service properties.
• If Volume Shadow Copy service is double-click it to open the service properties
• Click the Startup type list, click Automatic (Delayed Start), and then click Apply.
• Under Service status, click Start.
  

Event logs are special files that record significant events on your computer, such as when a user logs on to the computer or when a program encounters an error. Whenever these types of events occur, Windows records the event in an event log that you can read by using Event Viewer

Event Viewer tracks information in several different logs. Windows Logs include:

A warning is an event that is not necessarily significant, but might indicate a possible future problem. An information event describes the successful operation of a program, driver, or service.

• Security-related events: These events are called audits and are described as successful or failed, depending on the event, such as whether a user trying to log on to Windows was successful.

• Setup events: Computers that are configured as domain controllers will have additional logs displayed here.

• System events: System events are logged by Windows and Windows system services, and are classified as error, warning, or information.
