About auto image replication in NetBackup for OpenStack
The backups that are generated in one NetBackup domain can be replicated to storage in one or more target NetBackup domains. This process is referred to as auto image replication (AIR).
NetBackup for OpenStack 10.5 and later versions support AIR from a Media Server Deduplication Pool (MSDP) in one NetBackup domain to an MSDP in another domain. NetBackup uses storage lifecycle policies (SLP) in the source domain and the target domain to manage AIR operations.
The following diagram explains the architecture of using AIR between OpenStack Cloud A and OpenStack Cloud B. Backup images stored in the NetBackup media server A are replicated to the NetBackup media server B.
