Abstract
A method and apparatus for metadata favored replication in an active/active topology. When replicating data objects between multiple storage systems, metadata is sent first while the associated data content is sent at a subsequent time. Metadata is stored and made visible on a target storage system thereby reserving the object path in a namespace to reduce collisions in the namespace. After metadata is transferred to the target storage system, the target system performs collision processing to determine if an object already exists in the namespace prior to receiving the transferred metadata. After collision processing is performed, the winning object is made visible for access on the target storage system regardless of whether the associated data content has been transferred to the target system.
