About un-targeted AIR
The Auto Image Replication (AIR) feature of NetBackup (NBU) addresses the site-to-site replication
challenge by allowing storage lifecycle policies to duplicate selected images between NetBackup
Master Domains. The primary purpose of Auto Image Replication is to create off-site copies of
mission critical backups to protect against site loss.
Figure 1 (page 13) provides an overview of how AIR needs to be set up with HP OST v2.1 or
later. It displays some of the prerequisites that need to be satisfied before setting up AIR. Please
see the “AIR Prerequisites” (page 13) for complete information.
NOTE:
• Only un-targeted AIR operations are supported by HP OST v2.1 or later on NBU v7.6.
• Un-targeted AIR operations are not supported with HP OST v3.0 on AIX and HP-UX operating
systems.
