We are redesigning our backup infrastructure to backup files based on applictaion as opposed to server.One of the challenges is identifying wether netbackup can go accross the network and pull files from multiple systems provided an identifier is supplied and bucket them.We are well aware of the policy,tape pool,as well as multiplexing aspects of this.We are trying to see if this is possible.
 
You can certainly "bucket them" with a keyword but that's only a small part of the solution.  Scheduling your backups will be the real problem - an individual backup policy may only contain a file list that's common to all of the servers in the policy and you can have only one policy type (Standard, Windows, etc.) per policy.   In other words, an application that spans an Oracle database on a Unix cluster with a Windows file cluster is going to be really difficult to back up on an application-consistent basis since you'll need a minimum of 4 NetBackup policies just to do those backups.
 
You also have to decide what to do if one of the policies doesn't run or fails - does the entire application need to be rerun, or just the failed pieces?  That's something we can't answer for you.
 
It's all doable although you may need an external scheduler to help with this because of the limitations of what can go into a single NetBackup policy and the reruns that need to be done if part of the backup set fails.
