Configuring Storage Class for a Bucket

Functions

This operation sets or updates the default storage class of a bucket.

To perform this operation, you must have the PutLifecycleConfiguration permission. By default, only the bucket owner can perform this operation. The bucket owner can grant the permission to other users by configuring the bucket policy or user policy.

After the default storage class has been set for a bucket, if the storage class of an object is not specified during uploading, copying, or initialization of multi-part upload, the object storage class is the same as the default storage class of the bucket.

The default storage class of a bucket is Standard.
