Request elements

Element Type Required Example Description
StorageClass String No Standard The storage class of the bucket.
Valid values:
  • Standard (default value)
  • IA (Infrequent Access)
  • Archive
  • ColdArchive
DataRedundancyType String No LRS

The disaster recovery type of a bucket.

Valid values:
  • LRS (default value)

    If you specify LRS, OSS stores the copies of each object across different devices within the same zone. This way, OSS ensures data reliability and availability when hardware failures occur.

  • ZRS

    Zone-redundant storage (ZRS) uses the multi-zone(AZ) mechanism to distribute user data across three zones within the same region. Even if one zone becomes unavailable due to failures such as power outages and fires, the data is still accessible.

For more information about the storage classes and disaster recovery types of buckets, see Overview.
