Obtaining the Cross-Region Replication Configuration of a Bucket

Functions

This operation obtains the replication configuration information of a specified bucket. To perform this operation, you must have the GetReplicationConfiguration permission.

Authorization Information

To call this API, you must be the bucket owner or have the permission to obtain the cross-region replication configuration of a bucket. You are advised to use IAM or bucket policies for authorization. For details about OBS authorization methods, see Differences Between OBS Permissions Control Methods.

• If you use IAM for authorization, you need to use either role/policy-based authorization or identity policy-based authorization and configure the required permissions:
  • If you use role/policy-based authorization (IAM v3 APIs in the old IAM version), you need to grant the obs:bucket:GetReplicationConfiguration permission. For details, see Creating a Custom IAM Policy.
  • If you use identity policy-based authorization (IAM v5 APIs in the new IAM version), you need to grant the obs:bucket:getReplicationConfiguration permission, as shown in the following table. For details, see Creating a Custom IAM Identity Policy.

• If you use bucket policies for authorization, you need to grant the obs:bucket:GetReplicationConfiguration permission. For details, see Creating a Custom Bucket Policy.
