Abstract
A source worker node at a source site fetches a task from a message queue. The task specifies replicating a first object at the source site to a destination site. A request for a connection is issued from the source worker node to the destination site. The request is received by a load balancer at the destination site and assigned to a destination worker node. A connection is established between the source and destination worker nodes. A determination is made that the destination site does not include an object that is the same as the first object. Upon the determination, a deduplication is performed between the source and destination worker nodes of segments into which the first object has been divided. Deduplicated segments of the first object are transmitted from the source worker node to the destination worker node for storage at the destination site.
