How Do I Lock an S3 Object?

Amazon S3 object lock enables you to store objects using a "Write Once Read Many" (WORM) model. When using object lock you can prevent an object from being deleted or overwritten for a fixed amount of time or indefinitely. For information about object locking using the AWS CLI, AWS SDKs, and the Amazon S3 REST APIs, see Introduction to Amazon S3 Object Lock in the Amazon Simple Storage Service Developer Guide.

Before you lock any objects, you have to enable a bucket to use Amazon S3 object lock. You enable object lock when you create a bucket. Once you enable object lock on a bucket you can lock objects in that bucket. Once you create a bucket with object lock enabled, you can't disable object lock or suspend versioning for the bucket. For information on creating a bucket with object lock enabled, see How Do I Create an S3 Bucket?.
