Explanation

The error 'NoCredentialProviders: no valid providers in chain' is a standard AWS SDK credential resolution failure. The AWS SDK searches for credentials in a defined chain: environment variables, shared credential file (~/.aws/credentials), and then the IAM role attached to the EC2 instance. If no IAM role is attached to the EC2 instance, the entire credential chain is exhausted and this error is thrown. AWS Backint Agent uses the AWS SDK to authenticate with S3 and other AWS services, so without an attached IAM role granting the necessary permissions, it cannot obtain credentials and the backup fails. SSM Agent (A) is unrelated to credential resolution. Non-root binary ownership (C) would cause a permission error, not a credential error. VPC endpoints (D) affect network routing but not credential resolution.
