Same-region replication (SRR) allows you to replicate objects across buckets within the same region in an automatic and asynchronous (near real-time) manner. Operations such as the creation, overwriting, and deletion of objects can be synchronized from a source bucket to destination buckets.
Usage notes
- Billing
After SRR is enabled, you are not charged for the traffic that is generated when you use SRR to replicate objects in OSS. Each time an object is synchronized, OSS accumulates the number of requests. However, you are not charged for the requests.
- Replication time
In SRR, data is replicated asynchronously. Depending on the amount of data, it can take a few minutes to several hours to replicate data to the destination bucket.
Limits
- You can configure SRR between two unversioned buckets or two versioned buckets.
- The versioning status of two buckets between which an SRR rule is configured cannot be changed.
- You can manage two buckets between which an SRR rule is configured at the same time. Therefore, the object replicated from the source bucket may overwrite the object that has the same name in the destination bucket.
Enable SRR
Disable SRR
You can click Disable to disable SRR.

After you disable SRR, the replicated data is stored in the destination bucket. However, the incremental data in the source bucket is not synchronized to the destination bucket any more.
