Hello @KennethL_Cammie
Cloud Backup?
Backup sync failed?
Have you tried calling Norton LiveUpdate + Restart (not Shut down) machine?
Any clue with Security History → Cloud Backup?
Have you tried Repair Norton
Have you tried Reset to Default
Note: Reset to Default resets Cloud Backup
Have you reviewed: Security History → Cloud Backup → Advanced details here … review → # files failed to back up
for example:
Advanced details = click 
for example: 7 files failed to back up
========================================================
~ have you tried calling Norton LiveUpdate + Restart (not Shut down) machine?
~ have you tried Norton 360 → Troubleshooting?
fwiw ~ my boiler plate:
If your Norton is not working as expected and you’ve tried Troubleshooting → Reset to Default &or Repair Norton & clean re-install Norton 360…then…reach out to Norton support here.
Note: Reset to Default resets Cloud Backup
==============================================
Download and run the Norton 360 Remover tool for Windows here
==========================================================
fwiw ~ my Norton 360 Remover tool preference is Remove only…with scour File Explorer for remnants and CCleaner - Registry - Scan for Issues + CCleaner…back up the registry before making changes.

=========================================
fwiw ~ were my machine and I’ve tried Troubleshooting = I’d Remove & Reinstall or clean uninstall → clean install

AI Overview
If Norton cloud backup fails, check for insufficient cloud storage, ensure your Norton software is up to date, verify your backup settings, delete and recreate backup sets, and try running the backup again after a short period. You may also find a red cross (x) icon next to the backup status, which indicates a complete failure and requires further troubleshooting to resolve.
Possible Causes for Norton Cloud Backup Failure
- Insufficient Storage Space:
If you have used all your available cloud storage, new files will not be backed up.
An outdated version of Norton 360 can lead to backup issues.
Incorrect backup settings or an issue with the backup location can cause failures.
A corrupted backup set may prevent future backups from completing successfully.
Troubleshooting Steps
-
Check Backup Status: Look for the status icon next to your backup in the Norton app. A red cross (x) indicates a complete failure.
-
Check Cloud Storage: Verify your current cloud storage usage.
-
Update Norton Software: Make sure you are running the latest version of Norton 360.
-
Review Backup Settings:
-
Go to the Cloud Backup tile in your Norton product.
-
Select Advanced details or the Settings tab to review your backup set and settings.
-
Consider turning off “Back up common file types only” if it is set to on and you have files it is excluding.
- Delete and Recreate Backup Sets:
-
Exclude Problematic Folders: If a specific folder is causing issues, try excluding it from your backup.
-
Run Backup Again: After making changes, try running the backup again.

AI Overview
If Norton Cloud Backup sync fails, you should first check for insufficient online storage, slow internet, or issues with your Norton 360 program. Try restarting your computer and router, then use the Cloud Backup window to review your backup settings and add any files to the backup set, or reset your backup set to default. If these steps don’t work, you may need to exclude the "System Volume Information folder from your backup or use the Norton Remove and Reinstall tool to fix corrupted files.
Check for Basic Issues
- Internet connection:Ensure your internet connection is stable and not unusually slow.
- Storage space:Check if you have enough cloud storage space or if you need to upgrade your Norton plan.
- Norton program:Make sure your Norton 360 program is up-to-date and restart your computer.
Review Backup Settings in Norton 360
- Open Norton 360 and go to the Security dashboard.
- Select the Cloud Backup tile.
- Click Manage or Manage Files next to the backup set you want to update.
- Go to the Files tab and click Add to add any files or folders you want to include in the backup.
- Check the Settings tab for the option to “Back up common file types only” and turn it Off if it’s enabled, as this might be preventing files from syncing.
- Go to Excluded files → Manage and check if you’ve accidentally excluded the files you need to back up.
Troubleshoot the Backup Sync Failure
- Review Security History: Look for the specific backup failure message in your Security History to understand the cause.
- Reset Backup Set: If you see the “Failed to sync backups” message, try deleting the specific backup set that is failing and then create a new one.
- Exclude Specific Folder: If the backup is trying to back up the “System Volume Information” folder, exclude it from your backup.
