There are three retention periods you need to consider:
— Volume retention
— Job retention
— File retention
I suggest reading up on these in the documentation so that you 
understand what each of them does.  You can then adjust your pools, and 
update all of your volumes, as necessary.

You might want to consider virtual-full jobs as a part of that strategy.

You could fix your retention and then scan the pruned volumes back in 
using bscan.  By the sound of it, that would take a while, but it's doable.

What you need to keep in mind is that an "incrementals forever" strategy 
is also a "Bacula database grows forever" strategy.  That will 
eventually become a problem.
