Google Backup and Sync Account Already in Use?


How to fix the Backup and Sync account already in use?

I tried to sync 2 google drive accounts to backup & sync. I successfully did that and I can see 2 instances of the apps on the system tray. However, after I restarted, the second instance does not appear, my files are not synced, and I can not add it again because it said "account already in use". How can I fix this? Thanks.

Don’t worry, there are two proven ways for you to fix the Backup and Sync account already in use problem while using multiple Google Backup and Sync accounts. Just follow the detailed steps below.

Solution 1. Uninstall and Reinstall Google Backup and Sync

Step 1. Uninstall Google Backup and Sync

Please go to Start > Settings > Apps > Click Backup and Sync from Google, then select Uninstall to uninstall Google Backup and Sync.

Now, you could reinstall Backup and Sync after uninstalling Google Drive desktop app.

Step 2. Reinstall Backup and Sync from Google

1. Please go to Google Drive website to download the latest Google Backup and Sync app. Then double-click the installbackupandsync.exe on your computer to install it.

2. Once the installation is completed, you could log in to your Google Drive accounts and set up the Google Drive sync settings.

3. Then click the Backup and Sync icon on the system tray, and tap the three dots icon > Add New Account to add another Google Drive account.

4. Then set up the sync settings for the second Google Drive account just like the first time you set it up.

Note: Please do not add the same Google Drive account again, or you will get the error message you are already logged in.

Now, you could see the two instances of Backup and Sync on the system tray, which means there are 2 icons for your two Google Drive accounts. And the Google Backup and Sync account already in use problem will be fixed.

Solution 2. End All Google Drive Backup and Sync Instances and Restart

Besides, you have the other proven way to fix the second Google Backup and Sync icon missing problem. Unlike uninstalling and reinstalling, it’s easier to operate for you: End all Google Drive instances and restart Backup and Sync.

1. Right-click on the running icon of Backup and Sync, then tap the three-dots icon and select Quit Backup and Sync from the menu.

2. Then right-click the taskbar, and select Task Manager.

3. Find all instances of googledrivesync.exe (and GOOGLE~1.exe), tap them and click End Task.

End Backup And Sync Task Manager

4. Tap cmd in the Windows search box, and run as administrator, then run the following command:

"c:\program files\google\drive\googledrivesync.exe" /autostart (Replace the Google backup and sync path if necessary)

Auto Start Backup And Sync Cmd

5. After a few minutes later, the Google Drive Backup and Sync open, and all your child accounts will be listed on the system tray one by one.

6. If there only one Google Backup and sync instance appears, run the following command:

"c:\program files\google\drive\googledrivesync.exe" --child_process --profile_id user_ambdASDADAS

Let Backup And Sync Child Account Appear On System Tray


Change the profilie_id user_ambdASDADAS with your child Backup and Sync account default folder. And you can get the folder name at the location:

%localappdata%\google\drive\user_*** (under the  c:\users\user name\appdata\local\google\drive folder, and *** means a random string)

The primary Backup and Sync account default folder called user_drive is located on the same path.
If you have the third Backup and Sync account, you could do the same command with the right default folder to make it appear on the system tray.

After all the instances appear on the system tray, and then it will sync the files again. And the Backup and Sync account already in use error message will be solved easily.
