Will an Object Deletion in a Source Bucket Be Synchronized to the Destination Bucket?

  • If your cross-region replication rules are configured on OBS Console, object deletions in the source bucket will not be synchronized to the destination bucket by default.
  • If your cross-region replication rules are configured using the API, the synchronization depends on the setting of the DeleteData parameter.
    • If the value of DeleteData is Enabled, the deletions will be synchronized.
    • If the value of DeleteData is Disabled, the deletions will not be synchronized.

After the cross-region replication rule is enabled, objects that meet the following conditions are copied to the destination bucket:

  • Newly uploaded objects (excluding objects in the Deep Archive or Archive storage class)
  • Updated objects, for example, objects whose content or ACL information is updated
  • Historical objects in a bucket with Synchronize Existing Objects enabled (excluding objects in the Archive or Deep Archive storage class)
