LIVEUPDATE:
The NetBackup 6.5.4 LiveUpdate containers include all the files distributed as part of NetBackup 6.5.4. This allows customers to use LiveUpdate to populate their local LiveUpdate server with all files required to upgrade to 6.5.4. When a LiveUpdate policy is launched to upgrade to 6.5.4, the local host that is targeted for the update determines what set of files is required automatically. LiveUpdate Policies can be scheduled for specific clients to maximize NetBackup deployment.
