It's too late now now to change this, but with a setup like this it's better to run inital backups manually...

Bacula is smart enough to track job data on different pools. The typical setups I create all use a Full pool and one or more pools for differential and incremental backups. > Please let me know if my understanding is incorrect, and if Incremental and > Differential backups can only be made against a Full that's stored in the > same > pool (in which case, I need to radically change my volume retention). No need for that - I'd even say that one of the main reasons for pools with different retention times is the ability to recycle incremental / differential job volumes sooner than full backup volumes.
