Which solution allows HP Data Protector to manage low bandwidth data movement between backup hardware devices?

HP StoreOnce Catalyst is a protocol integrated with HP Data Protector that deduplicates backup data at the source before transmission, drastically reducing the volume of data sent across the network. This source-side deduplication makes it the correct solution for efficiently managing data movement between backup hardware devices in low bandwidth or distributed environments.

HP StoreOnce VTL emulation presents a virtual tape library interface to backup software but does not provide source-side deduplication or low bandwidth optimization for data movement.

HP StoreOnce Enterprise Manager is a centralized management and monitoring console for StoreOnce appliances, not a data movement or bandwidth optimization technology.

HP StoreOnce MAS targets provide backup target destinations via media agent servers but do not offer mechanisms for managing or reducing data movement over low bandwidth connections.
