### Description{% #description %}

Amazon S3 buckets should have versioning enabled to protect against accidental or malicious deletion and overwriting of objects. Without versioning (`versioning { enabled = false }`), deleted or overwritten files cannot be recovered, potentially leading to permanent data loss or loss of critical information. Enabling versioning (`versioning { enabled = true }`) allows you to preserve, retrieve, and restore every version of every object stored in the bucket, significantly improving data resiliency.

    aws = {
      source = "hashicorp/aws"
