This property controls media sharing, as follows:
Enable this property to allow all NetBackup media servers and NDMP hosts in the NetBackup environment to share media for writing. Do not configure server groups for media sharing.
Clear this property to restrict media sharing to specific server groups. Then configure media server groups and backup policies to use media sharing.
Clear this property to disable media sharing. Do not configure media server groups.
The default is that media sharing is disabled. (The property is cleared and no server groups are configured.)
