About this task

Prevent Client Modification is a system wide setting. When the Prevent Client Modification option is selected, the following requests are denied:
    • Delete Bucket requests
    • Any requests to modify an existing object's data, user-defined metadata, or S3 object tagging
      Note: This setting does not apply to buckets with versioning enabled. Versioning already prevents modifications to object data, user-defined metadata, and object tagging.
  • Swift REST API
    • Delete Container requests
    • Requests to modify any existing object. For example, the following operations are denied: Put Overwrite, Delete, Metadata Update, and so on.
