Media owner policy attribute

Active only for Media Manager type storage units or if the Policy storage attribute is Any Available.

The Media Owner property specifies which media server or server group should own the media on which backup images for this policy are written.

You can specify the following for Media Owner:

Any (default)	Allows NetBackup to choose the media owner. NetBackup chooses a media server or a server group (if one is configured).
None	Specifies that the media server that writes the image to the media owns the media. No media server is specified explicitly, but you want a media server to own the media.
A server group	Specify a server group. A server group allows only those servers in the group to write to the media on which backup images for this policy are written. All server groups that are configured appear in the drop-down list.
