Backup and sync never finishes 1 Recommended Answer 74 Replies 352 Upvotes

I recently switched over from the old photo upload desktop app to the new backup and sync app. I have 44,000+ photos already on google drive and now with the new app, no matter how many times I restart it, it always hangs. It makes it up to around 43k files sometimes but then always hangs or restarts. It has literally been backing up since I installed it about 2 weeks ago, non stop, 24x7, no matter how many times I kill it and restart it, log out and back in or uninstall and reinstall. I had another thread on this but someone closed it and now I cannot comment on that one anymore.

Hi Cris,

Welcome to the Google Photos Help Forum.

I do understand the inconvenience as your Backup & Sync is not syncing a few photos. Also, I appreciate you for trying to fix the issue yourself and letting us know the steps you have tried.

As none of the steps helped, I recommend trying the steps below in sequence, this may help in fixing the issue:
  • On your computer, click Backup and Sync.
  • Click More.
  • Select Quit Backup and Sync.
  • Reopen Backup and Sync.
If that doesn't help, please try the below steps as well:
  • Go to Backup and Sync.
  • Click the Backup and Sync icon in your computer’s toolbar.
  • Select View # unsyncable files.
  • Click Retry all.
For more details, please check the Help Center Article on error messages for sync problems.

Hope this helps.

It syncs new files without a problem. It just never stops syncing. I have tried restarting and reinstalling and it still just keeps syncing over and over and over and over. Its literally been syncing constantly for 2 weeks. The CPU on my computer has been spiked for 2 weeks. I never had this problem with the old Google Photo Uploader app.

Yes I have done this multiple times. I have also uninstalled backup and sync from Programs and Features and reinstalled it multiple times. The problem still persists. It has been syncing now for about 4 weeks straight I believe.
