Object Storage Service:CreateBucketDataRedundancyTransition

Last Updated:Dec 14, 2023

Creates a redundancy type conversion task for a bucket.

Usage notes

  • Make sure that redundancy type conversion is supported in the region where the bucket is located. This feature is supported in the following regions: China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Hong Kong), Japan (Tokyo), Singapore, Indonesia (Jakarta), and Germany (Frankfurt).

  • The redundancy type of the bucket must be locally redundant storage (LRS). You can only convert the redundancy type of a bucket from LRS to zone-redundant storage (ZRS).

  • The storage class of the bucket must be Standard, Infrequent Access (IA), or Archive. However, the storage class of objects in the bucket can be Cold Archive or Deep Cold Archive. Cold Archive and Deep Cold Archive objects are still stored as LRS after the change. You cannot change the storage redundancy type of a Cold Archive or Deep Cold Archive bucket.

  • To create a redundancy type conversion task for a bucket, you must have the oss:CreateBucketDataRedundancyTransition permission. For more information, see Attach a custom policy to a RAM user.

  • Each region has its own Object Storage Service (OSS) endpoints. For more information about regions and their endpoints, see Regions and endpoints.
