What has changed with Auto Image Replication
To use NetBackup Auto Image Replication (A.I.R.) with secure communications, you must establish trust from both the source and the target primary servers.
When you upgrade both the source and the target primary servers to 8.1 or later, you must update the trust relationship on both primary servers.
Note:
After the upgrade, if the trust is not re-established on both the servers, new storage lifecycle policies (SLP) do not work.
You can configure the trust relationship using the NetBackup web UI or the nbseccmd -setuptrustedmaster command.
For more information on trusted primary servers for Auto Image Replication, refer to the NetBackup Deduplication Guide.
