Datto Drive: Error - Unable to Sync Journal



This article provides troubleshooting steps to resolve the Datto Drive error message "Unable to sync journal."


This error can be caused by: 

  • Adding a folder without proper user permissions
  • A directory without proper permissions
  • The app not running under the correct permissions


1. Ensure all users have full read/write permissions on the local machine when syncing directories

2. Ensure the Datto Drive app is installed and running under an administrator account, or with sufficient permissions to read/write & execute files.

3. If you have verified that the application and users have the correct permissions, remove and re-add the machine's folder sync connection.

Recreating the connection

1. Right-click the connection and click Remove folder sync connection, as shown in Figure 1.

2. When prompted, click Remove folder sync connection.

3. Re-add the folder connection by clicking Add folder sync connection and specifying the path of the             folder you wish to add.

If the issue persists, remove the .csync _journal directories located in the sync folder by performing the following steps:

1. Open the destination folder on the target machine.

2. From the Windows Explorer View tab, check the Hidden items box.

3. You should see 3 .csync_journal files, as shown in Figure 5. Remove them, and restart the sync.

If the .csync files do not rebuild, investigate a larger permissions issue in your production environment. As an example, a NAS share may have received a firmware update which resets its drive permissions, resulting in this error.

If you have attempted all of the above steps, enable logging, recreate the error, and open a ticket with Datto Technical Support with logs attached for further assistance.
