How to fix error error-backup-controller in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'services.msc' and press Enter. Scroll down to 'Volume Shadow Copy'. Right-click it and select 'Start' if it's not running. If it's already running, right-click and select 'Restart'. This service is essential for creating backup snapshots. Also ensure 'Windows Backup' service is set to 'Automatic' and started.
2. 2 Open Command Prompt as administrator (Windows key, type 'cmd', right-click, 'Run as administrator'). Type 'vssadmin list writers' and press Enter. This shows all backup components. Look for any with 'Failed' or 'Error' status. If you see errors, note the writer name and then run 'vssadmin list provider' to check the provider status.
3. 3 If the Volume Shadow Copy service fails to start, check its dependencies. In services.msc, double-click 'Volume Shadow Copy', go to the 'Dependencies' tab. Ensure all listed services are running (like 'Remote Procedure Call (RPC)'). Start any that are stopped.
4. 4 Run the System File Checker and DISM tools. In the same Command Prompt, type 'DISM /Online /Cleanup-Image /RestoreHealth' and press Enter. Wait for it to complete (may take 15-20 minutes). Then run 'sfc /scannow'. This repairs system files that might be corrupt and causing the backup controller to fail.
5. 5 If you use third-party backup software, temporarily disable it and try Windows Backup again. If it works, the third-party software is conflicting. Update or reinstall it. Also, check if the backup destination drive is accessible and has enough space.
