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.
