How to backup Google Workspace data to Amazon S3.

Amazon AWS S3 cloud storage

Amazon S3 is a very affordable and flexible storage solution. It is probably the most-widely used cloud storage solution due to its high scalability, flexibility, reliability and security.

Compared to on-premise backup options, running CubeBackup on an Amazon EC2 instance and backing up Google Workspace data to an Amazon AWS S3 bucket is simply more stable and resilient, and offers better backup performance.

Google Workspace backup solutions

There are several solutions that can help you backup your Google Workspace data to Amazon S3:

  • Cloud-to-cloud backup solutions, like Spanning
  • Self-hosted backup solutions, like CubeBackup

Some Google Workspace cloud-to-cloud backup solutions act as a middle-man between Google's servers and the cloud storage provider (such as Amazon S3). All of your data is stored in the vendor's own storage with the cloud provider, so the vendor becomes the gatekeeper of your backup data, and all access to your data must be through them.

CubeBackup, on the other hand, leaves you in control of your data. Using Google APIs and Amazon APIs, CubeBackup allows you to back up your Google Workspace data to your own private Amazon S3 bucket directly, without acting as a middle-man. You retain control of the Amazon S3 bucket and all of your data without exposing it to any third parties. This allows you to view the physical files and folders of your backups, so you can copy or migrate the backup data to other storage locations if you wish.

Since CubeBackup leaves control of the Amazon S3 storage in your hands, you will need to create an AWS account on Amazon and apply for an S3 bucket. For more information, please visit

Create S3 bucket and IAM

Setting an Amazon S3 bucket as your backup location must be done just after the CubeBackup installation, during the initial configuration. For detailed information about how to apply for a private S3 bucket and corresponding Amazon IAM account, see detailed instructions in AWS S3 tab.

Once you have created your Amazon IAM account and S3 bucket, during the initial configuration of CubeBackup, you can select Amazon S3 as the backup location, then input the Bucket name, Access key ID, Secret access key values, select a Storage class and click the Next button. In the following steps, you can refer to the Initial Configuration instructions to complete all other settings.
