You can replicate your object data from the source bucket in one region to the destination bucket in another region by configuring cross-region replication rules. This feature can apply to a range of scenarios including cross-region disaster recovery, industry-specific compliance, data migration and backup, low access latency for customers, and easy data access for clusters from different regions.
After versionning is enabled, newly uploaded objects will generate multiple versions and take up storage space, so these versions of the object will also charge for storage.
For information on how to configure a cross-region replication rule in the COS Console, see Setting Cross-region Replication documentation.
You can configure and manage cross-region replication via REST API as described in the following API documentation:
You can directly call the cross-region replication method in the SDK. For more information, see the SDK documentation for the corresponding programming language below:
