Configuring a Default WORM Policy for a Bucket
Functions
This operation allows you to configure the default WORM policy and a retention period for a bucket.
With the bucket's default WORM policy, if you do not specify a WORM policy or a retention period when you upload an object to the bucket, the default policy will be automatically applied to the newly uploaded object. An object-level WORM policy requires configuring a specific date, which indicates an object will be protected until that date. For a default bucket-level WORM policy, a retention period is required, and the protection for an object starts when the object is uploaded to the bucket.
To perform this operation, you must have the PutBucketObjectLockConfiguration permission. The bucket owner can perform this operation by default and can grant this permission to others by using a bucket policy or a user policy.
- You can modify or even delete the default WORM policy of a bucket. The change applies only to the objects uploaded after the change, but not to those uploaded before.
- During a multipart upload, the object parts uploaded are not protected before they are assembled. After object parts are assembled, the new object is protected by the default bucket-level WORM policy. You can also configure an object-level WORM policy for the new object.
Other restrictions on the WORM retention configuration:
- The WORM mode can only be COMPLIANCE.
- The retention period can be set to 1 to 36500 days or 1 to 100 years.
