Hotfix for CubeBackup

The new version of CubeBackup, version 2.6.8, has just been released. This is a hotfix version to solve the problems caused by recent changes in Google Drive APIs. We strongly suggest all CubeBackup users upgrade to this version as soon as possible.  We are sorry for the inconvenience, but this upgrade is not optional.

What’s the problem in older versions?

A few days ago, Google made several modifications on its Drive APIs and caused some file-downloading operations in CubeBackup to fail. CubeBackup users might see lots of errors in the log files, such as “Failed on backup of Google Document entry: … Error message: One or more errors occurred. A task was canceled.”, or “Object reference not set to an instance of an object”, etc.  As a result, some Google Drive files were not successfully backed up locally. This problem happened randomly and just started a few days ago.

What’ new in CubeBackup 2.6.8?

This version is just an emergency hotfix for recent Google Drive backup problems. There are no new features added to this version. Due to the changes in Google Drive APIs, every CubeBackup users should upgrade to the new version as soon as possible.  We are sorry for all the trouble. However, as a client app completely based on Google APIs, CubeBackup must be adjusted to even minor changes in Google APIs.

Upgrade instructions:

  • To upgrade to the latest version, please select the “Check for updates” menu item in CubeBackup, then click the “Update” button. You need to exit CubeBackup and restart it for the new version to take effect.    NOTE: Simply closing the main window will not exit the application. To quit CubeBackup, please select “Exit CubeBackup” from the system tray in the right-bottom corner of the screen.
  • Or, you can quit and restart CubeBackup. CubeBackup will check for new versions every time it starts.

What if the upgrade failed?

There are possibilities the upgrade may fail and “Upgrade failed. You can try it again later.” message is given. To solve this problem, you can:

  • Download the CubeBackup hotfix file manually and unzip it into the installation directory for CubeBackup, like “C:\Program Files (x86)\CubeBackup“, to replace the old files.
  • Or, download the new version from  and reinstall it. All the application settings, configurations and user selections in old versions will be kept after the new installation, but you will be asked for the license key again to activate CubeBackup.

For some users, their Drive files backups were incomplete due to the errors in the last few days, how do I fix it?

To retry the backup for a specific user, you can open the local backup folder in Windows Explorer, then delete the folder for that user. For example, if the folder named “[email protected]” is deleted, CubeBackup will backup [email protected]‘s data completely from the beginning in the next backup cycle.

If you have any problems with this upgrade, please don’t hesitate to contact us.
