Windows 7 VSS and SPP problem when ran backup to external hard drive and Volume Shadow Copy Service problem wh

[chinhiunun]

Dear friends,
I encountered a problem that i can not backup my system by using backup and restore function in win7. I had it done before and i have a backup image in my external hard drive. Several days ago the system tried to backup again due to the set backup schedule, but it failed all the time.
Firstly popped up a window saying that: "A shadow copy could not be created. Please check "VSS" and "SPP", application event logs for more information. Details: A Volume Shadow Copy Service component encountered an unexpected error. Check the Application event log for more information. " and offering two options: 1. Try to run backup again, 2. Change backup settings. Because failed for the first one, so i clicked on the second one and another pop up:
"The backup application could not start due to an internal error: A Volume Shadow Copy Service component encountered an unexpected error. Check the Application event log for more information. (0x80042302)."
I searched the internet for solution telling that, like, start Volume Shadow Copy Service in Service, increase the space in disks for system protection, and reboot the computer, etc. I think i tried that all, but the problem is not solved at all.
Also, i tried restoring the system by using restore point, it failed again.
Is there anyone could help? Very appreciated!

It seems like you are facing issues with the Volume Shadow Copy Service (VSS) when trying to backup your system in Windows 7. The error messages you provided indicate that there are problems with creating shadow copies, which are essential for backup and system restore functions to work correctly. Here are a few steps you can take to troubleshoot and potentially resolve the VSS-related errors: 1. Check Volume Shadow Copy Service (VSS) status: - Go to "Services" by typing "services.msc" in the Windows Start menu search bar. - Locate "Volume Shadow Copy" in the list of services and ensure that it is set to "Started" and the startup type is set to "Automatic." 2. Check System Protection settings: - Right-click on "Computer" or "This PC" and select "Properties." - Click on "System Protection" in the left pane. - Ensure that protection is enabled for the drive where Windows is installed. You can adjust the disk space allocated for system protection here as well. 3. Increase disk space for System Protection: - If the allocated disk space for system protection is too low, increase it to ensure that there is enough space for shadow copies. 4. Check Event Viewer for more details: - Open the Event Viewer by typing "eventvwr.msc" in the Start menu search bar. - Check the Application and System logs for any related errors or warnings that might provide more information about the VSS failure. 5. Run System File Checker (SFC): - Open a Command Prompt as an administrator. - Run the command: sfc /scannow to scan and repair system files that may be causing the VSS errors. 6. Restart the Volume Shadow Copy Service: - Sometimes, restarting the VSS service can help resolve issues. You can do this by stopping and starting the service in the Services console. After performing these steps, try running the backup again to see if the issue is resolved. If the problem persists, further troubleshooting may be necessary, such as checking for third-party software conflicts or running additional diagnostics. Feel free to try these steps and let me know if you encounter any difficulties or if you need further assistance!
