What is the name of the feature that allows NetBackup to deduplicate data across multiple domains or sites using optimized duplication?

Auto Image Replication (AIR) is the specific Veritas NetBackup feature designed to replicate backup images from a source NetBackup domain to one or more target domains. It leverages NetBackup's deduplication technology to perform "optimized duplication," which ensures that only unique, deduplicated data segments are sent across the network to the target site. This process significantly reduces bandwidth consumption and replication time, making it ideal for disaster recovery and data distribution across geographically separate sites.

B. Storage Lifecycle Policies (SLP): An SLP is a policy framework that automates the management of a backup image's lifecycle. It can initiate an AIR operation, but it is not the replication technology itself.

C. Cloud Catalyst (CC): Cloud Catalyst is a feature used to deduplicate backup data before it is sent to a cloud storage target. Its primary function is cloud storage optimization, not inter-domain replication.

D. Universal Shares (US): Universal Shares allow a NetBackup appliance to present storage as a standard NFS or CIFS share for protecting unstructured data, which is unrelated to replicating backup images between domains.
