"What are some policy managers for implementing file archiving and where do these policy managers exists?"
Policy managers take your business rules about the information being managed, then implement those rules to move, store and delete information in the enterprise. Trying to find a policy manager can be tricky because they are not necessarily discrete hardware or software products. It's really a feature that is built into numerous solutions. Generally speaking, policy managers will run in software on host servers or on appliances within the network or on storage subsystems.
