DataRedundancyType String No LRS

The disaster recovery type of a bucket. Default value: LRS.

Valid values:
  • 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 mechanism to distribute user data across three zones within the same region. Even if a zone becomes unavailable due to unexpected events such as power outages and fires, the data can still be accessed.
