Release of CubeBackup 3.1

Following the successful release of CubeBackup version 3.0, we received a great deal of helpful feedback from the CubeBackup community. We have carefully reviewed all of your ideas and suggestions and are proud to announce CubeBackup 3.1.

New features:

  • Team Drive backups can now be disabled.
    Some groups, like schools, may wish to only back up a few teacher or VIP accounts instead of the entire userbase, in order to save disk space. Team Drive backups are now optional.
  •  Automatic update checks return.
    CubeBackup will once again automatically check for new versions. With this feature, you will be notified whenever an update is available on our website.
  • Spam and Trash mail messages are now included in the backup
    CubeBackup 3.0 only backed up those mail messages (and appropriate labels) that were in the “All Mail” folders, omitting “Spam” and “Trash” messages. This has been fixed in the new version.
  •  Faster Gmail backups.
    The Gmail backup algorithm has been improved to be even more efficient.
  • Bug fixes.

We strongly recommend that all clients upgrade to CubeBackup version 3.1, whether they are currently using CubeBackup 2.x or CubeBackup 3.0, in order to benefit from the latest changes.

How to Upgrade CubeBackup from 2.x to 3.0

CubeBackup 3.0 is fully compatible with previous backup sets, so the upgrade process is safe and easy.

However, because of library changes made in the new version, upgrading through the menu in version 2.x will not work. A new install is necessary.

We suggest performing an on-site upgrade on the same computer running CubeBackup 2.x, so that settings and configuration data are automatically carried over to the new version.

To upgrade CubeBackup from 2.x to 3.0:

  1. Quit CubeBackup 2.x.
    Note: Simply closing the CubeBackup window does not quit the app; you need to select “Exit” from the CubeBackup icon in the Windows system tray.
  2. Uninstall CubeBackup 2.X
  3. Download CubeBackup 3.0 from
  4. Install the downloaded package.
  5. Start the new version of CubeBackup.
    • CubeBackup 3.0 will keep the settings used on the earlier version without asking you to configure it again.
    • CubeBackup 3.0 will employ an incremental backup on the data backed up by the old version.
  6. You can alter the parallel backup settings as well as network throttling using “Settings”-> “Options…”->”Throttling”.

If you have any problems with the upgrade, please feel free to contact us at

Release of CubeBackup Version 3.0

Today, we are pleased to announce the release of CubeBackup 3.0!

We know that many of our clients have been eagerly anticipating this new version for their G Suite backup. CubeBackup 3.0 incorporates many changes and improvements, including:

1. Team Drive Support
Ever since Google launched Team Drive in 2017, it has been an integral part of Google Drive, bringing convenience and flexibility to collaborative projects. Team Drive backups are now well supported in CubeBackup 3.0.

2. Much Faster Backup Speeds
Our new parallel backup algorithm dramatically improves backup speeds. Instead of backing up one user account at a time, CubeBackup 3.0 can handle multiple users simultaneously, fully utilizing your internet connection and resulting in backups that are up to ten times faster.

3. Bandwidth Throttling
Of course, faster backups naturally consume more bandwidth. To ensure that CubeBackup 3.0 doesn’t interfere with your other work, we have included throttling controls to set limits and schedule how much of your internet connection may be used at different times of the day.


4. New Gmail Backup Algorithm
The Gmail backup algorithm has been redesigned for faster backups that take up less space.

5. Better User Management
User management is easier than ever, as new employees can now be automatically added to the backup list.

6. Improved Logging
Error logs now contain more information and more accurate messages.

7. New Google APIs adoption
The latest Google APIs are more stable and more efficient.

8. Bug Fixes

2018 CubeBackup RoadMap

2018 will be an exciting and busy year for CubeBackup.

We have been hard at work on version 3.0, which is only a few months away. Many new features and changes have been incorporated into this version, including parallel backups, Team Drive support, and the ability to run CubeBackup as a service. A more complete list of changes has already been posted here.

At the same time, development of version 4.0 is already well underway. Here are some of the new features to look forward to:
1. Time Machine Backup
All older versions of Google Drive files will be kept, as well as snapshots of the entire Google Drive structure.

2. Backup to Cloud Storage
CubeBackup has always allowed full G Suite backups to local storage, including local disk, NAS or SAN. Version 4.0 will add the ability store your G Suite business data backups on Amazon’s S3 cloud service.

3. Full Platform Coverage
Version 4.0 is being completely rewritten in Go on the service side, along with a new web UI for configuration and operations. This will make CubeBackup platform independent so it can easily be deployed on both Windows, and Linux.

Version 3.x is fully compatible with version 2.x, which means the upgrade should be smooth and incremental backups will still work. However, version 4.0 will not be compatible with earlier versions. A new complete backup will have to be taken.

Version 3.0 should be available in 2 or 3 months.
Expect version 4.0 later this year.

If you have any suggestions for our product, please feel free to contact us at Thank you!

Expected features in CubeBackup version 3.x

We are currently working on the next major update of CubeBackup, Version 3.0. A lot of improvements will be added in the new version.

1. Parallel backup
CubeBackup will allow you to choose how many accounts can be backed up in parallel. This will greatly improve the backup speed for large organizations who have fast Internet connections.

2. Bandwidth throttling
Users can limit the backup speed in office hours, which can prevent CubeBackup consuming too much network bandwidth in the day time.

3. Run as a service
Most users run CubeBackup on server operating systems, like Windows Server 2012. Making CubeBackup running as a service provides users more flexibilities and convenience.

4. Administrator email notification
Daily/weekly backup statistics, error reports, and other notifications will be sent to G Suite Domain administrators via email. Administrators will get the latest information for the backup without checking logs.

5. Team drive support
Team drive is a new feature in Google Drive and is very useful for collaboration. New version of CubeBackup will support team drive backup.

6. Improved log
More information will be added to backup/restore/error logs.

7. Bug fixes
Many bugs will be fixed in the new version.

8. Restoring the whole account
Currently, CubeBackup allows you to restore any files/data for a user when you selected the files and click the “Restore” button. In future versions, Google Apps administrators can restore a whole account with just one click, or even restore all data from one account to another account. This feature might not be available in version 3.0, but should be added to a later release, like version 3.1 or 3.2.

9. Linux version
We got a lot of requests asking for the Linux version. It is still under development and is expected to be released in a few months. The good news is: CubeBackup’s first Linux Version will have all the features as its Windows version.

We are always happy to hear feedbacks from our users, so please feel free to contact us ( if you have any questions.

How to solve the “Authorization failed” problem in the initial configuration

The initial setup of CubeBackup is a little complicated, and some of our users might run into the “Google Apps authorization failed!” error when clicking the “Test” button in the initial configuration of CubeBackup.


If you have carefully followed the instructions at, but still failed to pass the authorization test, please check the followings steps:
NOTE: The following items are listed in descending order of likelihood.

1. In a few cases, G Suite domain-wide authorization needs some time to propagate. So you can just wait for several minutes and then click the Test button again.

2. Are the Admin SDK, Drive API, Calendar API, Contact API and Gmail API enabled in Google API console?   A quick way to confirm: all of the above APIs should be listed in API Manager -> Dashboard -> Enabled APIs.

3. The Client Name in your Google App/GSuit  admin console  -> Security -> Advanced settings -> Manage API Client access should be the created Service Account’s client ID (e.g.:10847638222459), not an email address.


4.  Make sure that  “Enable API access” is checked in Google Apps admin console -> Security -> API reference -> API access. Generally, “Enable API access” is checked by default.

5. If your computer is running a fresh installation of Windows 7 or Windows Server 2008, and you have not installed all of the updates, the problem may be that you are missing hotfix KB2468871 for the .Net Framework 4.0. Download the hotfix here, and install it. You may be required to restart your computer before the update takes effect.

6. Please ensure that  port 443 and  port 993 are not blocked by your firewall/proxy.

7. Try CubeBackup on another computer to see if it works there.
