Cross-bucket replication enables you to replicate objects from a source bucket to a destination bucket. This feature is well suited for use cases such as remote disaster recovery, industry compliance, data migration and backup, access latency reduction, and access to data located in different regions.
Special use cases:
Once versioning is enabled, you can create multiple versions for any new object uploaded. Each of these versions occupies your storage capacity and is billed for storage equally.
You can configure a cross-bucket replication rule in the COS console as instructed in Setting Cross-Bucket Replication.
You can configure and manage cross-bucket replication rules through RESTful APIs as described in the following API documents:
You can directly call the cross-bucket replication method in SDKs. For more information, see the SDK documentation for the corresponding programming language below:
