# Cross-region replication

* Cross-region replication is a bucket-level feature that enablesautomatic, asynchronous copying of objects across buckets in different AWS regions. 
* The object replicas in the destination bucket are exact replicas of the objects in the source bucket. 
* They have the same key names and the same metadata. Existing objects of source bucket will not be copied to destination bucket. 
* The source and destination buckets must be versioning- enabled. The source and destination buckets must be in different AWS regions. You can replicate objects from a source bucket to only one destination bucket.
