Specifying the short name of the client to protect with Auto Image Replication and BMR
You must specify the short name of the client when you install NetBackup client packages on the computer that you want to protect with Auto Image Replication and Bare Metal Restore (BMR). You must also specify the short name of the client in the backup policy that you created on the primary domain. That policy backs up all of the client's local drives and gathers the client configuration that BMR requires. The DNS of the secondary or the tertiary domain cannot resolve the fully qualified name during a BMR recovery of that client at the disaster recovery site.
