About secure communications in MSDP for Auto Image Replication
Starting from NetBackup 8.1.2, MSDP supports secure communications in Auto Image Replication (AIR). When you run AIR, MSDP secure communication is set up between two media servers from two NetBackup domains. There must be a common CA and the two media servers must use the same CA to verify the certificate security. The source MSDP server uses the CA of the target NetBackup domain and the certificate that is authorized by the target NetBackup domain. You must manually deploy CA and the certificate at the source side MSDP server before using AIR.
