How can I authenticate access to an S3 bucket using IAM role of my EC2 instance?

When backing up data to Amazon S3 storage, CubeBackup normally requires an IAM user with an access key to authenticate. Hwoever, some organizations may feel unsafe entering access keys directly in third-party applications.

If you are running CubeBackup on an EC2 instance, you may opt to assign an IAM role directly to the instance as a more secure solution with fine-grained security.

Configure S3 authentication during the initial setup

  1. Create an IAM role that grants access to your S3 bucket, and attach it to your EC2 instance. For detailed instructions, please refer to AWS documentation: Using IAM roles to authenticate applications deployed to Amazon EC2.

  2. In Step 2 of the CubeBackup setup wizard, select S3 as the storage type, enter the Data index path and S3 Bucket, but leave the Access key ID and Secret access key fields empty.

  3. Click Next. CubeBackup will perform a storage writing test to verify the permissions before proceeding. If successful, complete the subsequent steps by following the instructions here.
