Bucket policy Bucket policies are used for resource-based authorization and can be directly configured by the bucket owner on the graphical console for access authorization. 2019-01-21 All regions Use bucket policies to authorize other users to access OSS resources
Set or modify the storage class of an object When uploading an object, you can set the storage class of the object to Standard, IA, or Archive. The setting takes effect immediately after the object is uploaded.

You can convert the storage class of an object among Standard, IA, and Archive by performing a CopyObject operation. The time period that is required for the conversion to take effect reduces from days to seconds.
