How to save on backup SW licences!

I would like to share with you one CIO tip that can easily be implemented and you could save some money. Usual situation is that you have backup of file systems, system backups or database backups. By default architecture of backup systems is to put backup agent on each server you want ot backup and then configure it through backup SW application. I don't need to mention that licensing policy is to charge each agent. Each exstension requires new backup licenses. Not looking good isn't it?
Here is the tip. You have two prerequisites:

1. custom made scripts that are coping backup content to backup servers
2. backup server (cluster)

Procedure is to create custom made scripts that upload backup content to backup server, on backup server you put backup SW agent that handle content to tapes or other. There is no need for one server, you can logicaly group servers you like. On illustrations you can see old and new backup setup.
