Hi Ratty69,
I would suggest you to try the steps mentioned below.
Step 1: Disable your anti-virus completely and then try to run the backup
Your virus scanner might be preventing you to run the backup. Disable your antivirus software and see if you can re-run the backup.
**Note:**Running the computer without firewall or the anti-virus software is a potential threat to the computer; make sure to enable the security software after completing the troubleshooting steps and after identifying the issue.
Step 2: To execute a command
a. Click on Start; in the start search type cmd
b. Right click on cmd.exe and “Run as administrator”
c. Type the following command and press Enter.
net localgroup administrators NetworkService /ADD
Now try running the backup and check if you’re able to run the backup.
Step 3: Perform a system restore to the date when the backup was working fine

Additional information:
When you receive this error “Windows Resource protection could not start the repair service”
during system file checker scan, then you need to check the status of the Windows Module Installer Service in Microsoft Services Console. The service should be running and the service type should be set to manual.
Hope this information is helpful and let me know if this worked.
