Which statement is true regarding the unique benefits of the HP StoreOnce Catalyst?

StoreOnce Catalyst does not provide federated deduplication across all HP StoreOnce Backup systems; deduplication domains are maintained per system or replication pair, not globally federated.

HP StoreOnce Catalyst enables deduplication to occur directly on the application server or backup server prior to data transfer, which is called source-side or client-side deduplication. This fundamentally reduces the volume of data traversing the network and accelerates backup and restore jobs by eliminating redundant data before transmission.

This choice describes inline or media-server-side deduplication before transfer to a centralized target, which is a traditional approach and not the unique differentiator that Catalyst provides.

This statement is factually incorrect; rehydration of data does occur when restoring data between HP backup platforms.
