Error: could not get determine if bucket supports versioning: Access Denied

Challenge

Veeam Kasten for Kubernetes is unable to monitor or refresh the retention period of the data in the S3 bucket and cannot calculate the lock duration based on your retention setting because of this issue.

This will show up as an error message in the notification bar:

error: can't connect to storage: could not get determine if bucket '<bucket-name>' supports versioning: Access Denied

Cause

This error occurs when the IAM role attached to the S3 bucket doesn’t have s3:GetBucketVersioning permissions.

Solution

Review the documentation and ensure that the required permissions for S3 and the additional permissions required for creating and maintaining immutable backups are configured correctly.
