Response elements

Element Type Description
ReplicationProgress Container The container that stores the progress of CRR tasks.

Parent node: none

Chile node: Rule
Rule Container The container that stores the progress of the CRR task corresponding to each CRR rule.

Parent node: ReplicationConfiguration

Child nodes: ID, Destination, Status, and Progress
ID String The ID of the CRR rule corresponding to the CRR task.

Parent node: Rule

Child node: none
PrefixSet Container The container that stores prefixes. You can specify up to 10 prefixes in each CRR rule.

Parent node: Rule

Child node: Prefix
Prefix String The prefix used to specify the object to replicate. Only objects that match the prefix are replicated to the destination bucket.

Parent node: PrefixSet

Child node: none
Action String The operations that can be synchronized to the destination bucket.
You can set Action to one or more of the following operation types.
  • All: PUT, DELETE, and ABORT operations are synchronized to the destination bucket. This is the default value.
  • PUT: write operations are synchronized to the destination bucket, including PutObject, PostObject, AppendObject, CopyObject, PutObjectACL, InitiateMultipartUpload, UploadPart, UploadPartCopy, and CompleteMultipartUpload.

Parent node: Rule

Child node: none
Destination Container The container that stores the information about the destination bucket.

Parent node: Rule

Child nodes: Bucket and Location
Bucket String The destination bucket to which the data is replicated.

Parent node: Destination

Child node: none
Location String The region in which the destination bucket is located.

Parent node: Destination

Child node: none
TransferType String The link used to transfer data in CRR.

Valid values:

  • internal: the default link.
  • oss_acc: the link in which data transmission is accelerated.
HistoricalObjectReplication String Indicates whether historical data is replicated. Historical data indicates the data stored in the source bucket before CRR is enabled for the source bucket.
Valid values:
  • Enabled: indicates that historical data is replicated to the destination bucket. This is the default value.
  • Disabled: indicates that historical data is not replicated to the destination bucket. Only data uploaded to the source bucket after CRR is enabled for the source bucket is replicated.
Progress Container The container that stores the progress of the CRR task. This element is returned only when the CRR task is in the doing state.

Parent node: Rule

Child nodes: HistoricalObject and NewObject
HistoricalObject String The percentage of the replicated historical data. This element is valid only when HistoricalObjectReplication is set to Enabled.

Parent node: Progress

Child node: none
NewObject String The time used to distinguish new data from historical data. Data that is written to the source bucket before the time is replicated to the destination bucket as new data. The value of this element is in the GMT format.

Example: Thu, 24 Sep 2015 15:39:18 GMT.

Parent node: Progress

Child node: none
