How Are Job Priority Catagories Linked to Storage Lifecycle Management?

Hello--

We are running Netbackup 7.5.5 and are gathering information to start configuring our current backup policies to include Platinum, Gold, Silver and Bronze job priority classifications.

One of the concerns that was brought up is how are these priority classifications linked/related to storage lifecycle management? We want to avoid any unintended consequences if we configure these priorities.

Thanks,

Stephen
