DataRedundancyType String No

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

Valid values:
  • LRS

    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 in case of hardware failures.

  • 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.

Note For more information about the type of disaster recovery, see Overview.
