Hi all!
Does anybody know how AIR transfer images from one to another NBU domain? I mean, which protocol/application transfer data between NBU domains? and if the data transferred is compressed or encripted?
Thanks!!

AIR is really just optimized duplicatio and it happens over IP and between the storage servers (DataDomain / PureDisk). The "magic" with AIR is that after the optimized duplication has taken place, the images are read and imported to the catalog of the target Master. The data is deduplicated so its compressed, I dont think it encrypted in transit but then again with out the deduplication database you won't be able to understand what is being transferred.

To correct the statement:
"The "magic" with AIR is that after the optimized duplication has taken place, the images are read and imported to the catalog of the target Master."
to:
The "maigc" with AIR is that after the optimized duplication has taken place, the meta data that was included with the images is imported into the catalog of the target Master saving time from having to read and import directly from the images themselves.

Whether it is encrypted or not is controlled using OPTDUP_ENCRYPTION. Search this forum for that keyword to read other questions/points/topics surrounding it uses and considerations.
AIR replication uses propriatery application protocols over TCP/IP (not UDP) - i.e. not NFS, not SMB, nor does it used any of the traditional multitude of different application and/or file transfer protocols.
The ports reference guide covers the ports used by AIR:

Advice: If you stumble across this article in your searches, then be careful as it is only talking about optimized duplication within a single domain, and not AIR between two different NetBackup domains:
