Sometimes issues can be resolved by clearing the local database that ElephantDrive stores on your device to keep track of what data has been uploaded. Instructions on how to do this can be found below:
Click on the ElephantDrive Icon in your System Tray/Menu Bar -> select "Preferences" -> Go to the Advanced tab -> Put a check on the local database check box -> Click "Ok".
This will restart your ElephantDesktop. Once restarted your Backup jobs will re-scan and upload any new/modified data they find.
