PutBucketReplication - Object Storage Service - Alibaba Cloud Documentation Center

Configures data replication rules for a bucket. Object Storage Service (OSS) provides two data replication features: cross-region replication (CRR) and same-region replication (SRR).

Usage notes

You can use data replication features to automatically synchronize operations, such as the create, overwrite, and delete operations, that are performed on objects from a source bucket to a destination bucket. When you use data replication features, take note of the following items:

Data is asynchronously replicated. The time that is required to replicate data from the source bucket to the destination bucket may range from a few minutes to a few hours. The replication time varies based on the data size.
The source bucket and the destination bucket cannot have the same name.
When you use CRR, the source bucket and the destination bucket must be located in different regions. When you use SRR, the source bucket and the destination bucket must be located in the same region.

For more information, see CRR and SRR.

Request parameters

Parameter	Type	Required	Example	Description
ReplicationConfiguration	Container	Yes	N/A	The container that stores data replication configurations. Parent nodes: none Child nodes: Rule
Rule	Container	Yes	N/A	The container that stores data replication rules. Parent nodes: ReplicationConfiguration Child nodes: Destination, HistoricalObjectReplication, and ID
RTC	Container	No	N/A	The container that stores the status of the Replication Time Control (RTC) feature. Parent nodes: Rule Child nodes: Status
Status	String	No	enabled	Specifies whether to enable or disable the RTC feature. The RTC feature can only be used for CRR tasks. Default value: disabled. Valid values: enabled disabled Parent nodes: RTC Child nodes: none Note For more information about the regions supported by the RTC feature, see RTC.
PrefixSet	Container	No	N/A	The container that stores prefixes. You can specify up to 10 prefixes in each data replication rule. Parent nodes: Rule Child nodes: Prefix
Prefix	String	No	source1	The prefix that is used to specify the object that you want to replicate. Only objects whose names contain the specified prefix are replicated to the destination bucket. The value of the Prefix parameter can be up to 1,023 characters in length. If you specify the Prefix parameter in a data replication rule, OSS synchronizes new data and historical data based on the value of the Prefix parameter. Parent nodes: PrefixSet Child nodes: none
Action	String	No	ALL	The operations that can be synchronized to the destination bucket. If you specify the Action parameter in a data replication rule, OSS synchronizes new data and historical data based on the value of the Action parameter. You can set the Action parameter to one or more of the following operation types. Default value: ALL. Valid values: ALL: indicates that the PUT, DELETE, and ABORT operations are synchronized to the destination bucket. PUT: indicates that write operations are synchronized to the destination bucket, including the PutObject, PostObject, AppendObject, CopyObject, PutObjectACL, InitiateMultipartUpload, UploadPart, UploadPartCopy, and CompleteMultipartUpload operations. Parent nodes: Rule Child nodes: none
Destination	Container	Yes	N/A	The container that stores information about the destination bucket. Parent nodes: Rule Child nodes: Bucket and Location
Bucket	String	Yes	destbucket	The destination bucket to which data is replicated. Parent nodes: Destination Child nodes: none
Location	String	Yes	oss-cn-hangzhou	The region in which the destination bucket is located. Parent nodes: Destination Child nodes: none
TransferType	String	Yes	oss_acc	The link that is used to transfer data during data replication. Default value: internal. Valid values: internal: the data transfer type that uses the default data transfer link of OSS. oss_acc: the link in which data transmission is accelerated. You can set the TransferType parameter to oss_acc only when you create CRR rules. Parent nodes: Destination Child nodes: none
HistoricalObjectReplication	String	No	disabled	Specifies whether to replicate historical data from the source bucket to the destination bucket before data replication is enabled. Default value: enabled. Valid values: enabled: indicates that historical data is replicated to the destination bucket. disabled: indicates that historical data is not replicated to the destination bucket. Only data uploaded to the source bucket after data replication is enabled for the source bucket is replicated. Parent nodes: Rule Child nodes: none
SyncRole	String	No	aliyunramrole	The role that you want to authorize OSS to use to replicate data. If you want to use SSE-KMS to encrypt the objects that are replicated to the destination bucket, you must specify this parameter.
SourceSelectionCriteria	Container	No	N/A	The container that specifies other conditions used to filter the source objects that you want to replicate. Filtering conditions can be specified only for source objects encrypted by using SSE-KMS.
SseKmsEncryptedObjects	Container	No	N/A	The container that is used to filter the source objects that are encrypted by using SSE-KMS. This parameter must be specified if the SourceSelectionCriteria parameter is specified in the data replication rule.
Status	String	No	Enabled	Specifies whether to replicate objects that are encrypted by using SSE-KMS. Default value: Disabled. Valid values: Enabled: indicates that objects encrypted by using SSE-KMS are replicated. Disabled: indicates that objects encrypted by using SSE-KMS are not replicated.
EncryptionConfiguration	Container	No	N/A	The encryption configuration for the objects that are replicated to the destination bucket. If the Status parameter is set to Enabled, you must specify this parameter.
ReplicaKmsKeyID	String	No	c4d49f85-ee30-426b-a5ed-95e9139d****	The customer master key (CMK) ID that is used in SSE-KMS. If the Status parameter is set to Enabled, you must specify this parameter.

Error codes

Error code	HTTP status code	Description
InvalidTargetBucket	400 BadRequest	Possible causes: The error message returned because the source bucket and the destination bucket have the same name. The error message returned because the destination bucket does not exist. The error message returned because the source bucket and the destination bucket are owned by different Alibaba Cloud accounts.
InvalidTargetLocation	400 BadRequest	The error message returned because the region of the destination bucket is different from the region specified in the XML body of the request.
BucketReplicationAlreadyExist	400 BadRequest	The error message returned because a data replication rule already exists between the source bucket and the destination bucket. To configure a data replication rule between the source bucket and the destination bucket, delete the existing rule.
BadReplicationLocation	400 BadRequest	The error message returned because the region of the destination bucket is invalid. You can call the GetBucketReplicationLocation operation to query valid regions in which the destination bucket can be located.
